This page contains information about installing the latest D-Link DWL-G122 driver downloads using the D-Link Driver Update Tool.

D-Link DWL-G122 drivers are tiny programs that enable your USB hardware to communicate with your operating system software. Maintaining updated D-Link DWL-G122 software prevents crashes and maximizes hardware and system performance. Using outdated or corrupt D-Link DWL-G122 drivers can cause system errors, crashes, and cause your computer or hardware to fail. Furthermore, installing the wrong D-Link drivers can make these problems even worse.

Recommendation: If you are inexperienced with updating D-Link device drivers manually, we highly recommend downloading the D-Link DWL-G122 Driver Utility. This tool will download and update the correct D-Link DWL-G122 driver versions automatically, protecting you against installing the wrong DWL-G122 drivers.

For a little more money you can get a WiFi adaptor that does not need drivers.
http://www.netgear.com/products/details/WGE101.php
This device connects via Ethernet and configures via web browser. It costs more, but you can upgrade to Tiger or use this on an OS 9 machine without worrying about drivers.

I have been told by Netgear that the WGE101 wireless bridge is no longer being made. They have another model, the WGE111 that should work.
http://www.netgear.com/products/details/WGE111.php
It is called a Wireless Game Adaptor but will work with a computer and will configure with a web browser.
I'm told by Netgear it also supports WPA encryption, although not WPA with a RADIUS server. I don't see WPA encryption on the web site however.

Has any one found usable driver for this product's older brother, the DWL-122 (802.11b)? The drivers that came with the product as well as the ones directly off D-Link's support site were quite flaky in OSX.

if you go to the Singapore dlink site
http://www.dlink.com.sg/products/support.asp?pid=175#drivers
and there are drivers there.
the ones I have used were v1.4.7 and they worked fine. Install then plug in the card and away you go.
also has an uninstall as well which is nice.

has it been reliable? and which OS are you on?
-Travis

I would like to know which os you are using becaue when you call dlink support they tell you they have yet to prove that it works on anything higher then 10.2. I could get it to work but if my ibook g3 running 10.3.7 tried to go to sleep while connected wirelessly my whole computer freezes. It happened several times to the point I just returned the usb adapter. I was hoping to find something that is a little cheaper thin an airport card but it seems like my only option.

on different web sites of D-Link I only found version 1.3.2 which is unstable.
but on www.macupdate.com (search for wireless) I found version 1.4.7 which works very well until now.
no more sleep problems or lost connection after restart.

The dlink drivers for jaguar actually work in Tiger. I am using them right now. However, my model is a DWL-122. You have to uncheck the port in the networking control panel before you unplug the unit otherwise you get a kernel panic. Have fun...

This is the post I've been looking for. Those kernel panics were a huge pain, but I went into Network Port Configurations and unticked the adaptor, and when I unplugged the adaptor there was no multilingual death screen. Yay!!! Thanks.

I would be interested in more information or sources on the potential damage issue. I personally have not seen this and have run my internal Airport card (802.11b) and my Orininco even sharing my wifi from one to the other with SunShield configuring my Powerbook(TiBook) as a router.
Maybe it is the poor antenna performance of the TiBook that protected me from damage <kidding really on this>.
As for the other comment regarding alternative options, somewhat off topic but I will also make mention of Buffalo's WLI2-TX1-G54 Ethernet converter. I have been pleased with their products and they are very likely to be compatible with Airport/Airport Extreme including base stations and WDS. I use the 802.11g card in my card bus. It is recognized by the system as an airport card and displays in the menubar as such.
I could not figure out how to leave my internal card in and add a network interface for the Buffalo card (did strange things like duplicating both entries and could not separately control). I removed my internal airport card and now have a 'native' 802.11g card without the Extreme and much better signal. I also have the option of adding an external antenna (which I did, similar to the WLE-DA from Buffalo but smaller, easily fits in my pack).
I do need to remove and install the card when packing up but a small price for real wifi capability (even gets signal driving with Macstumbler/iStumbler; have not played with KisMac so far on this card).

The transmitters in WiFi cards are powerful enough to destroy the sensitive receivers if connected directly. There is a very fast electronic switch in the card that connects the antenna to either the transmitter or receiver, depending on what it wants to do, but never both at the same time.
When you put two cards very close together, there's a small chance that enough power could couple from the antenna of one when it's transmitting to damage the receiver in the other. You'd probably have to have the antennas almost touching for this to happen, but there is a chance.

This chance only happens with two wi-fi cards? Or the potencial damage issue can happen between this USB Device and the antenna of my linksys router?
Because I was testing the router and the device all on the same table. If I put this in a distance of more than 50cm it´s safe?
I know, I can put wires to cross all over, but I use the router for my notebook that travels around my house... why not use it for my mini mac and for my other computer and get free of wires?
I have to tables side by side, I was hoping to have the notebook resting beside my desktop and in the other table the mini and the router. Will everything explode if I don´t get more than 50cm of distance between then? :)

Isn't AirPort Express another product, and AirPort Extreme the built-in WiFi card? Or do you mean that we can damage an AirPort basestation by placing our PB too close to it?

I have a g3 500mhz iBook running 10.3.8 and am having no luck with this DLW-G122.
Under system profiler/extensions it says that the RT2500USBWirelessDriver is not loaded.
Any suggestions?
Thanks,
Gareth

Not sure if you figured this out or not, but I was running into the same problem with a bondi rev A iMac running 10.3. I later discovered there are 2 installers I needed to run from Ralintech to get things working. I'm using version 1.09 and it works great (even after sleep).
1.) Download and unzip version 1.09
2) Install the USB driver package first (STA_2500USB)
3) Restart and wait... (for some reason, it takes a good 20 minutes for the resart to complete...)
4) Install the _MACOSX package.
5) Restart and wait again...
6) Attach the DWL-G122 dongle and the wireless utility will open.
7) Open the network preferences and you'll get a pop up telling you about the new network connection. From that point just follow the instructions from D-Link (BTW, I couldn't get their driver to work..)

To the poster that mentioned it, yes I did mean Airport Extreme, not Express, sorry.
The possible damage problem which I mentioned I put in mostly to cover myself, you probably wont see any noticable damage to the performance or operation, but I really cant be doing with people sending me angry emails saying that I killed thier $80 Airport card.
This driver works first time on my G4 ibook 12 running 10.3.8, I have yet to test it on anything older, I should have mentioned this.

And just to say, to all those people suggesting alternatives, these are infact better wireless solutions for your mac, but sometimes, like in my case, you have one of these spare, or you've bought one thinking it will work and it doesnt. In which case theres still hope through this driver.

So, I removed the Airport card completely, plugged in the DWL-G122 installed the ralink driver and nothing. System preferences is not showing the USB Card control panel. Any ideas?

Looks like there might be some magic voodoo or at least specific firmware versions to make the dlink DWL-G122 work with a Mac.
Thus far, using my USB2 native iMac G5 and Mac mini, I can't get the DWL-G122 to get recognized by the Ralink drivers http://www.ralinktech.com/supp-1.htm .
Neither the 1.0.6 or 1.0.7 drivers work. They install a generic WirelessUtilityUSB application which does not recognize the USB adapter.
System Profiler does see the USB adapter and gives the following profile:
Speed: Up to 480 Mb/sec
Product ID: 14084 ($3704)
Bus Power (mA): 500
Vendor ID: 8193
The adapater I got is Model DWL-G122, HW Ver A2, FW Ver 1.01 P/N BWLG122NA.A2.
For now I would recommend users steer clear of the G122 adapter as its compatibility is not certain.

Not sure if you figured this out or not, but I was running into the same problem with a bondi rev A iMac running 10.3. I later discovered there are 2 installers I needed to run from Ralintech to get things working. I'm using version 1.09 and it works great (even after sleep).

The D-Link DWL-G122 A1 or A2 use the Intersil Prism chipset, which is not currently supported. The Ralinktech drivers are for the B version.
ps. MacMall sucks. They list USB wireless dongles as being mac compatable, when they are not.

The kernel dependancies can be fixed by editing:
/System/Library/Extensions/RT2500USBWirelessDriver.kext/Contents/Info.plist
And replacing the strings
<string>1.0.7.0</string>
with
<string>1.0.0d1</string>
This will allow the driver to load.

My G122 h/w ver. is B1, f/w ver. is 1.00.
Hardware detail in system profile are:
802.11g W:
Version: 0.01
Bus Power (mA): 500
Speed: Up to 480 Mb/sec
Manufacturer: ANI
Product ID: 0x3c00
Vendor ID: 0x2001
It neither work with driver ver. 1.0.7 nor 1.0.6.
After modified the info.plist of them, still didn't work either.
Brand new Mac mini 1.25G with pure Tiger.
I don't know what wrong is with the G122.
Please kinkdly help me if you guys know what's wrong with it.
Or sent me the driver which dose work in your case.
I'll appreciate.

I experience the same problem. I also noted that the profiler can see the dongle without any driver installed. If the Ralink driver is installed the profiler fails to pick the dongle up.

nooooooooooooooooooooooooooo
I bought a DWL-G122/RE specifically because of this thread.
I should have read all the comments! The hardware is A2 and neither the Ralink drivers nor the singapore Dlink drivers work.
Has anyone had any luck making the A1 or A2 work on a mac?

According to RALINKtech forums (see here: http://61.222.76.235/phpbb2/viewforum.php?f=3& ), there are a number of other USB dongle devices that work, so long as the guts of the dongle are truly the RA2500USB.
Here's the list from RALINK: http://ralink.rapla.net/
Among the other things worthy to note, RALINK has GPL'd the driver set for Linux...
I think there is a successful relationship for mac airport alternatives and tiger/panther/jaguar users in the far future with that kind of thinking by RALINK...
The fix listed above about changing the driver name in the .plist is on the fora there, too... apparently, the developer merely forgot to update one key... (see here: http://61.222.76.235/phpbb2/viewtopic.php?t=558&postdays=0&postorder=asc&start=15 )
AND THERE's MORE!
I've seen the Linksys 802.11g USB dongles at my local Sam's club for a song... some of them are compatible...
Belkin USB Dongle F5D7050 v2000
Linksys USB Dongles WUSB54G v4, WUSB54GP v4
CNet CWD-854
See full list here: http://ralink.rapla.net/
The important thing to note is that you MUST get a version of those model numbers that includes the RA2500USB chipset or the drivers will obviously not work... (I think that's why some folks are having trouble here).
My local Best Buy has DWL-G122 ver. A1 on the shelf.
Radio Shack has ver. A2...
I lucked out and K-Mart nearby had a clearance DWL-G122 v. B1 (the RALINK 2500 one) for $19.00... take off the $10 mail in rebate D-Link is offering, and my clamshell iBook is wireless..
:-D
N.B.: There is still an issue of the dongle needing the reinsert after system sleep for pre-tiger versions... but there's ways to script a reconnection automatically.
For a $9 wireless airport alternative, with GPL'd drivers (think Kismac), I don't think you can shake a stick at this deal.

I don't believe KisMac supports the DWL-G122 yet. It only supports the DWL-122... Please correct me if I'm wrong as I'd love to get it working...

If I go to the Ralink RT2500 chipset page at http://ralink.rapla.net/ and search ebay for any of the models found in the USB column, I should be able to use anything that matches on my Mac. Correct?

Any other gotchas? Would all of these still work on Mac OS 10.4.5?

I have an IMac G4 running 10.2.8 and just purchased the D-Link DWL-G122 usb adapter (hw ver B1, fw ver 2.02). I have no Airport card installed on this machine. I downloaded the most recent drivers for the 2500 chipset (1.0.7.0 I believe), and installed them. Restarted the mac, plugged in the device and everything seemed to be working correctly. The new network connection for the adapter displayed in the control panel, and the Wireless Utility program launched when I plugged in the adapter.
I was able to see both of my access points in the wireless utility. One is an airport (graphite) and the other is a recent Linksys model. I had WEP turned on for both and was never able to actually establish a connection. I turned off WEP on the Airport station and when it restarted, the DWL-G122 was able to connect to it.
Unfortunately, I moved some items on the desk and the adapter got unplugged. After a kernal panic and a restart, I was able to see both base stations in the utility again, but have not been able to establish a connection to either. I've tried uninstalling/reinstalling the drivers/utility multiple times, but no success. I can see bases listed in the site survey, but can't connect (I've tried turning them off so only one is on at a time too). The USB adapter isn't broken, because if I plug it into my Dell laptop it works fine and can connect to either base.
Okay, for the actual question.. Am I missing something obvious to get a connection? Is it possible the kernal panic messed up something that uninstalling/reinstalling the drivers/utlity won't correct, and if so, what do I need to look into?
For anyone that has gotten a DWL-G122 to work, what steps did you take?
Additionally, assuming I can get this working again (without WEP activated on my access points), is there a trick to getting the connection to work with WEP?

I'm surfing using 10.2.8 now. This tip worked wonders! I'm connecting to a DLink DI-624 wireless router and the only problem I haven't been able to solve is that I need to set the wireless router to broadcast the SSID. WEP and WPA-PSK works fine, though.
I got the odd kernel panic too, but I found they don't happen if you plug in and unplug the usb adapter when you're logged in. It's not detected if you boot with it plugged in and if you shutdown/restart with it plugged in then you're risking a kernel panic.
The only other thing is that I need to do a little 'coaxing' to get a DHCPOFFER. I've even had to go so far as to manually set the IP address but after I do that once I can switch back to full DHCP and it will connect automatically across reboots until I try to connect to a different wireless network.

Got mine working!
osx 10.3.x
dwl-g122
rev B1 fw: 2.02
Drv1.0.7.0

Was there a trick to it? What steps did you go through?
Thanks!

Install the proper driver as mentioned above.
reboot
install usb device
wifi util will pop up (good sign)
launch network tool and it will show the detection of the new network device.
apply
then configure things as needed....

I couldnt get mine to work, but it picks up the network etc.. but wont connect. I have the G122 B1 version but a F/W 1.00 you mentioned yours were a 2.02 im not sure if the F/W would make a difference..
Are you able to give a more descriptive detail how you got yours to connect to network? thanks.

I just got the DWL G122 - model B1 - F/W 1.00
I am trying to use this on the Imac 400, using the Radlink drivers (tried both 1.6 & 1.7) my os x was able to pick the wireless USB & the wireless network however i cannot connect.. (im a little confused with putting details under os x network settings or even try and fiddle around with the radlink wireless utility, it just wont connect - nor any lights are showing up on the usb G122) can somebody give me some advice how to connect to the wireless network?
Powrslave - you mentioned you got yours working, are you sure your F/W is 2.02?? that might be the problem as mine's at F/W 1.00 - does anyone know whereabouts where i can get the latest firmwire?
I got the G122 working nicely on the PC so i know its not faulty.
Any tips/advice would be appreciated!!!!

This is the best tip ever! It works great - even gets better link percentage than on windows with d-link software.

I bet a bunch of people are buying this thing off Amazon after it was plugged on kk.org's 'cool tools' and being, like, 'hwa?'
Before I found this thread I wrote D-Link asking why there wasn't any Mac software in my box.
They wrote back and said that it was not a Mac-compatible product. When I get home I will definitely try the Rad driver's mentioned above and pray . . . but, yeah, don't expect any help from the actual D-Link company.

i just bought the d-link dwl-g122. i downloaded the ralink driver(http://www.ralinktech.com/supp-1.htm) dated 2005/11/29 DRV 1.2.00 for OS 10.4.x
I am running a flat panel G4 with OSX 1.4.3
it works fine !

Hi!
I just bought mine too:
dwl-g122
rev B1 fw: 2.03
Drv 1.2.0.0
Running on OSX 10.4.x
I was able to get it working with my linksys WRT54GS without having WEP enable. After I have WEP enable the utility says that is connected but I´m not able to surf on internet anymore.
Does anyone have any idea how can I fix it?
In the box of my DWL-G122 I have a stamp 'MacOS compatible' and it comes with a driver from D-LINK. Has anyone tried to use this driver?

Bought mine yesterday. It works, as long as WEP is not enabled. After much research, I found that WPA personal worked, with a 13-character password (you set all this stuff in your AirPort Admin Utility). Every report I found concerning this version of the Driver with this specific dongle and WEP enabled was the same: it didn't work. You can connect to the base station, but no Internet!
Without any WEP (which is totally unsecure), it worked... and now, with WPA, it does too, and I'm so glad! I think I'm gonna write a simple walkthrough of all the steps, from beginning to end.

Mr Vx

Fry's Electronics has the DLink DWL-G122 Revision B with Firmware v2.02 for $49 and then you get a $15 mail in rebate so the DLink only ends up costing $34.
Those who buy a Dual Core/Quad Core G5 and didn't custom order their Mac wire Airport should get the DLink instead. Even though you can see the Airport slot in the Dual Core system there are no rails to support it and the Antenna wire doesn't fit the Airport Extreme card. I'm really blown away that Apple made the Airport Extreme a customization option only (like the Bluetooth) for the Dual/Quad Core G5 systems. You can order just the Dual/Quad core specific Airport Kit from SmallDog.com for $99 but they warn you a technician should install it. Buying the DLink is a much better, cheaper, and safer alternative.
Good luck and I hope this is helpful information for everyone who bought a Dual/Quad system thinking you could add the Airport later!

Hi just in case
I just got a new D-Link QWL G122 Version B1 the one that will work with Macs
I have an old G4 450 mghz, running OS 10.4 Tiger. The driver that work is the driver for OS 10.3 1.0.7.0
Itried ll the other drivers for 10.4 none worked until I used the one for OS X.03.
Hope this help

yes the 10.3 drivers worked for me as well

I got a G3 ibook very cheapily at the end of Apple's PowerPc era. I realized though, that buying an airport card would kill the concept of getting a computer so cheaply. So I bought the DWL G122 off of ebay.
It took me awhile to figure this out, but to install it you have to be in the ROOT account.
Turn on root account access, and run the install program from root. Reboot and the computer should find it just fine.
after this is done, log back in and JUST THE ROOT ACCOUNT OFF IMMEDIATELY. running in root is like driving a car with the engine hood open!!!
Also sorry for the paranioa but i am not responsible for whatever happens to your computer in root.
Nicky
P.S.------i'll come back with a more detail version of how to do this later.

This is a reply to cornuto's post of 27 Feb-
I have a d-link DWL-G120 USB dongle that I am trying to get to work on an old Clamshell running 10.3.9. I downloaded the Prism driver you mentioned (from binaervarianz.de), but had absolutely no luck getting it up and running. I also tried the old drivers (1.4.7) for the DWL-122 with no luck (tried both stock settings and changing the device in plist.pref, apparently this driver is for the PrismII chipset). The DWL-G120 is supposed to have the Prism54 chipset, but there is no interface that I can figure out to use with the driver from binaervarianz.de like there is with the old 1.4.7 driver (it drops a setup into system prefs that makes configuration really easy). If there is any advice or direction that you could offer, I'd be eternally grateful. The dongle is a DWL-G120 H/W Ver: B1, as I recall the device ID was 5181 in system profiler. Thanks!

I haven't read all of your post (it's late at night), but I think the following should clarify:
- There can be different chipsets in D-Link DWL-G122 USB and D-Link DWL-G120 USB.
- DWL-G120 USB: usually Prism2 chipset.
- DWL-G122 USB: usually RT2500 chipset (from ralinktech).
- The problem: There are different versions of these two cards around, so you cannot tell by the model name alone which chipset you have. Read the other posts above to find more details on this.
I hope this helps.

anyone know how the dwl-g122 or dwl-122 work on a macbook? Thanx

StiG ...nyc

I don't know if anyone ever got this working, but I took the following steps to get this working under Leopard 10.5.1
1. You need to to be able to get onto the router access page from another PC / Mac on your network or know a free IP address in the range DHCP is giving out the dongle might use.
2. Install drivers.
3. Reboot.
4. Plugin dongle
5. Open Prefs pane, select network and enter key as usual.
6. The dongle connects, but you don't have internet yet.
7. Log into the router from another machine and see if you can find the IP address of the dongle. If not, just entering a valid IP address from the DHCP range might work.
8. open Network prefs and the new Ehternet port the drivers created.
9. Tell it you connect using DHCP with manual IP addy
10. Enter IP addy from step 7.
11. Bish bosh, after a few seconds you are connected.
12. You can now switch to DHCP only.
13. IP address is given out to the dongle and you're up and running.
14. Go back to the Dlink Prefs Pane and save the profile so it connects on each reboot.
