Hey I just got a DWL-G650, does anyone know if this one has been modded yet?

Has anyone successfully gotten multicast working with the ADM8211 driver? The driver does indeed work for standard TCP and UDP, but I'm having trouble with mcast -- specifically NetAtalk complains about not being able to open a multicast socket on the 8211 device in my system.
Any ideas? I've written to ADMTek and received no response. 6/8/2003

You have two options:
- a) Find decrypt.pm on CPAN (www.cpan.org) (I think it is in package Filter-1.29). If you cannot find it post a message
here and I'll upload or email it to you. You only need this if you are installing package which was compiled for RedHat.
- without problems.
I prefer option (b) since in my case option (a) didn't work even after fixing the module references and kernel calls (the Redhat module is compiled for kernel 2.4.18 so my guess is it won't work even if you install decrypt.pm). 05/24/03 ---
I tried to compile driver ADM8211 in my Mandrake 9,1 (kernel 2,4,21), but you to the following error:
Can't locate Filter/decrypt.pm in @INC (@INC contains: /usr/lib/perl5/5.8.0/i386-linux-thread-multi /usr/lib/perl5/5.8.0 /usr/lib/perl5/site_perl/5.8.0/i386-linux-thread-multi /usr/lib/perl5/site_perl/5.8.0 /usr/lib/perl5/site_perl /usr/lib/perl5/vendor_perl/5.8.0/i386-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.0 /usr/lib/perl5/vendor_perl .) at ./install line 2. BEGIN failed--compilation aborted at ./install line 2.
how to decide this?

ADM 8211 drivers
The official ADMTEK webpage (see below) now has the source drivers for their ADM8211 chip and they compile and work perfectly. They can be found under download and support (the descriptions of the windows and linux drivers are switched around). Actually they do not distribute full sources, because one of the files required to build the module is distributed only as binary. You can find it on their homepage (http://www.admtek.com.tw/download/ADM8211.htm), but one of their techies sent me the tarball via e-mail. Feel free to download from here for the time being: http://156.46.205.41/~lars/ADM8211_src.tar.gz. Should work in Mandrake 9.0 laptop (if have kernel headers/source installed), it is not full open source but its nice to see the step in the right direction from these guys.
Great news on Linux, Michael Wu and Jouni Malinen are working on a full open source linux driver. http://aluminum.sourmilk.net/adm8211/ By the time of writing this it works only on kernel 2.6 (but may be patched for 2.4), and doesn't work with rev20 of the cards. Monitor mode works. Help will be appreciated.
There is a full open source driver for *BSD, called atw, by David Young.
There is a patch for ADMTek linux drivers that may allow the use of monitor mode.
DWL-650
This card comes in two major flavors and lots of minor tasts. The earlier cards use a generic prism 2.5 chipset. The newest ones have sitched to a newcommer ADM8211 chipset.
The DWL-650 comes in many flavors, L1, K1, H, + etc. The variations are both firmware and hardware. You can poke through the driver and find clues.
ADM 8211 chipset
A precompiled linux driver for ADM8211 (new DWL-650 card revision) can be found at http://www.longshine.de/anonymousFTP/adm8211.tar.gz. it is compiled for kernel 2.4.18-3 (redhat 7.3?) but does not include source code for recompiling it. 14 Mar 2003
This card has a Bus of CardBus - is this good or bad?
Card Bus is a 32-bit bus architecture, as opposed to PC-Card or PCMCIA which uses a 16-bit bus. A wider bus (i.e. 32-bit) means the input/output from the computer to the card is faster. This may or may not increase the overall throughput of the card for data transmition. Think ISA::PCMCIA as PCI::CardBus.
I don't know about speed, but this card REQUIRES CardBus; most of your ISA-pcmcia based cards are only 16bit PCMCIA. Some of the PCI based PCMCIA adapter cards do support 32bit cardbus, but it's not ideal.
PCMCIA Type I described the physical dimensions of the first cards, usually SRAM-type cards. They were very slim, about the thickness of two or three credit cards. Type II cards are a bit thicker. They "bulge" in the middle, away from the rails. Type III cards are thicker still: they take up the space of two Type II slots, effectively preventing the use of the second card slot unless a PCMCIA extender of some sort is used.
Ok, HOLD ON A MINUTE!! I've got a DWL-650 working just fine in an old Cyrix 486DLC laptop with a 16-bit pcmcia interface. (As far as I can tell; it's a PD6710 ISA-PCMCIA bridge) The D-Link cards don't have those little golden bands on the connector, so I don't think the DWL-650 is cardbus. In fact, I think it's almost identical to the Netgear MA401, another prism2 reference design based card. And that card states explicitly on its box that it is a 5V, 16-bit, PCMCIA Type II.
There are two different boards under the dwl650 model number. one is cardbus complete with gold band and one isn't! prism2 vs adm8211
jrm7200 @at@ hotmail .dot. com
DLINK indicates that this card is Cardbus. The pics show a gold band.

-- wireless @at@ 31338 .dot. com
Dlink claim this needs CardBus to work, but I have it running under Windows 98 in an old Toshiba Satellite 110 under Windows 98. The problem seems to be with Dlink's install files - they assume Cardbus & go all Device Manager/Code-7 if they don't get it. The way out of this is to modify install file netcw10.inf and reinstall. Search Google groups on netcw10.inf & dwl-650 for the detail.
Prism 2.5 chipset
DWL-650 (H/W rev J3) is based on the Intersil Prism 2.5 chipset. Win2k drivers from D-Link are far from perfect (they don't seem to support profiles, a feature I need in order to use my laptop both at home and school) I'm using the reference driver from Intersil, which is newer and has profile support (get it at http://www.intersil.com/design/prism/ss/p2smtrx.asp#-Prod_Driver_Package_Exe). 22 Feb 2003
Also, the Prism 2.5 has the Host Access Point feature, I got it working on linux (w/ PCI-Cardbus bridge bundled with DWL-650 in DWL-500 PCI 802.11b package). It was much cheaper for me to add a wifi card on my linux server/router than buying a separate access point... see http://hostap.epitest.fi for instructions. Etienne, mailto: etienne dot dube at polymtl dot ca
This card (DWL-650) works well in Linux. Hopefully it will be supported in *BSD soon.
Actually mine ALMOST works with OpenBSD 2.9, it has a driver and comes up as wi0 interface, but I haven't been able to connect to it with my Orinoco station. I suspect it is just a brand to brand interopt issue (not the right combination of settings). Stephen Gutknecht
Update: It works in FreeBSD now.
Drivers: linux pcmcia-cs linux wlan windows
I bought a DWL650 planing to mod it as discussed below but it was very diferent inside. The good news is it had a connector already soldered to the card waiting for a pigtail (well almost). Read the details and see the pic's here: http://www.geocities.com/james3pa/DWL650.html 12/23/02
DWL-650+
DWL-650+ is an 802.11b card by Dlink. The + feature allows Dlink products to operate at 22Mbps under the right conditions.
07/01/2005 - Does anyone know how to mod this version? Is it as simple as connecting to that antenna connector on the top-side? Here is a respost of pictures of a DWL-650+ since the previous ones are no longer available. I've got this working on my Toshiba laptop running Knoppix http://www.knopper.net from CD. However Knoppix 3.4 didn't come with the drivers for it so I had to search out the acx-100 (acx100-0.2.0pre8_plus_fixes_6.tar.bz2) project and compile them for myself.
Top-side: There seems to be an antenna connector at the edge of the plastic shell. If I connect to that, do I need to do any soldering changes (perhaps on the built in antenna)? I can't seem to pry off the shell around the antenna part though. Any suggestions? 
Bottom-side:

So is my the DWL 650 my best bet for a card with external antenna capabilities? I saw them at CompUSA this week for $50...the model number in the advertisement is DWL-650+. Any difference? And also, I'll be using whatever I get on win2k most definitely, and probably win98 as well. Is there any disadvantage to mounting a flush-with-the-card antenna jack, as opposed to one that hangs out of the card? Also, what about using the 650 as an AP? Anything to worry about there? Thanks!
-Matt
Note: I am pretty sure I've read the 650+ uses a non-prism chipset and it might not be fully compatible with 802.11b. I think they use some non-standard tricks to bump the throughput up to 22mbps. NicholasHart
11/10/2002 - I am getting a bunch of the DWL-650+ cards with the new TI ACX100 chipset. I am assuming totally different board design. Has anyone taken one apart yet to check for a possible external antenna connect? OmegaF
Historic info on DWL-650+
Here is a picture of 650+. Please let us know whether it can be modified.
Thanks! But, please remove the front of the card, which is easy at this point, and post a picture. The rest of the card just comes apart but removing the little metal "braids" on the sides. Look in the sides, the alternating metal is a small strip that just comes off each side, then the rest of the card comes apart very easy. We need to see the TOP of the card, your showing us the BOTTOM. -OF
Thanks for the instruction. It looks like there is already a antenna connector on board.
Here is some more info on these cards and using an external antenna:

Hope you find it useful. Will
Here's a mirror of the site at Guerrilla Net http://www.guerrilla.net/reference/80211_mod/dwl-650_ext_antenna/index.html
Q. Will's site seems to be still down, does anybody have a copy of the DWL 650 external antenna mod? Karl 29/8/2002
I modified one of these cards, and found that you don't need to take the whole thing apart to get to the soldering points. Here are directions:
- Turn the card upside down.
- gently pry up at the seam of the gray plastic with your fingernails. Pull from the very tip of the card (farthest from the pcmcia connector), and pull the bottom piece of plastic up. The 4 plastic pins holding the bottom piece of plastic to the top piece will come loose. Don't try to pull it loose from the card yet, though.
- You can now peer in to the cavity and see where you're going to have to solder.
- Now, with small, pretty sharp flathead jewler's screwdriver, you can pry the bottom metal casing up just enough to release one edge of the bottom plastic piece. It has 2 small tabs which hold it in. Once you can wiggle one of the small plastic tabs loose, the whole bottom piece will slide out.
- be careful not to deform any of the metal pieces with the screwdriver, because you won't be able to get it flat again. Be patient, and don't force it. It will come loose.
- once you have the bottom plastic piece off, you'll have full access to the important side of the circuit board, without having to fully remove the metal case, or pulling any glue loose.

I got one of these on sale at Fry's for $70, and it blinked really pretty after install, but when I restarted the drivers kept crashing my Win2K laptop on bootup (both the ones on the CD and a reinstall with the latest from their website), so I am returning it. Just thought you should know there may be Win2K issues. What a bummer. - Jason (Portland)
I had issues with the drivers for Win2K on the CD but the ones on the website worked just fine. Did you try using a different laptop with Win2k? Are you sure the wireless card wan't defective? Are you sure that your PC-Card slots are working fine? Are you sure your AP is working fine? Just for the record I'm using a Toshiba Satelite Pro 4280 with Win2K -TomO'Hern
I just purchased the 650+ and similarly had problems with the install. If go the Install new hardware route in win2k, it looks like it installs the XP drivers, leading to it crashing on startup. You have to remove the card and bad drivers and go to the CD to do the install. I think I actually went to the w2k directory to install it, but running setup.exe from the cd seems to get by this problem.. Bruce [Laguna Niguel - USA]
I purchased similar card in France under reference DRC-650 sold under the "Neteasy by Dlink" brand. I actually don't know the difference between DRC/DWL models... anyway, they work well with Linux and orinoco_cs driver or the prism2 (HostAp mode for Access Point emulation) on Linux 2.4.17. - Olivier Berger (Puteaux - France)
Boy, I'm glad I got the orinoco_cs driver working in 2.4.9-21 on RedHat 7.2. The wvlan_cs driver would take about 5 minutes to get a lock on the AP and then 15 to 20 minutes later it would bomb out. The orinoco_cs driver had one caveat on my system. I had to add this to /etc/modules.conf:
- options orinoco_cs ignore_cis_vcc=1
Someone mentioned on a list that they "even added this option and it still didn't work." Well, I added it just to see why orinoco_cs wasn't working for me and Voila! the entire network was connected and ready to go albeit this stuff in /var/log/messages:

Hey, I just picked this card up From MicroCenter in Kansas, $64 with a $25 mail-in. Works Excellent under FreeBSD 4.6 with bsd-airtools. You do have to do a little symlink in the kernel source to make it work, but you don't need the kernel patches anymore. It just works (you have to symlink bat/common.h to the wavelan_ieee.h driver in /usr/src/sys first). I have no problems with any of the prism2 specific programs in bsd-airtools including the prism2 options for dstumbler. So far, this is the BEST Wardriving setup I've used. I'm looking forward to adding the antenna connector and picking up a nice omni to mount on top of my car! ax0n
This is another one external antenna mod for DWL-650 http://www.seattlewireless.net/index.cgi/DWL650ExternalAntennaMod

Just bought an antenna kit from hdcom.com this works great you just cut of the connector from the pigtail HD provides in their HD19669 and solder it to the board.Then when you need the antenna you just screw the cable onto the end of the pigtail. I cut my pigtail down so it only sticks out a 1/4 inch from the card. Here is the direct link for the HD product.http://www.hdcom.com/bundles.html#HD19669. Ben
Returning at the pcmcia/cardbus issue, started above: I looked into the install file "netcw10.inf", but was unable to modify the cardbus instructions into pcmcia instructions. Did anyone else had more luck? Sven Hello .
I had success modifiying "netcw10.inf" so I could use the DWL-650 with my ancient Toshiba 410CS running win98se. To do this I installed the older 1.32 drivers from the DLink site and after installation, went to control panel>system and unistalled the card. I then found the file netcw10.inf in windows\inf and inserted the additional code after [PRISM_PCMCIA.reg]. I obtained the additional code from the post referred to earlier in this page. I inserted the card and it reinstalled and the led on the card started flashing. After this WLAN expert and Aerosol worked fine. Cheers, Glenn.
It seems as if a current DWL650+ has a built-in antenna connector. What kind of connector is this and where can i get it? any idea?
Here are some photos:
top bottom board with connector board with connector
[11/19/03 EDIT - PaulR] Yes, I have finally confirmed after posting pics and askign questions for months - that is an U.FL connector, and is ready to be hacked. All you need is a U.FL pigtail/connector and a very small hole in the top of the antenna plastic, and you have an external antenna. The U.FL specs even say that it will re-direct the circuit, so it isolates the board traces when the connector is pushed into it.
Be aware, though, U.FL connectors were designed for QC testing of the cards, thus might not be up to many insertions/removals?? Don't know yet, but I can't find a discussion of it anywhere.. so I dunno..
Can you give me any tips on disassembling the DWL-650+. I am also interested in adding an external antenna if anyone knows how.
Tnanks

Just bought a DWL-650 rev. P? I did an antenna mod for it and made up a webpage. Check it out!
-- NoBlunts
This is my external antenna mod for DWL-G630 rev B1

some HELP?
Some images from my dwl 650 rev P, dont understand how that antenna works, and neither how to mod it and put an external antenna.
Any ideas? thx
