From: Adam Boileau To: <[EMAIL PROTECTED]> Hidey ho all. After bleating about my wireless lan woes a week or so ago on the list, I'm pleased to say that thanks to the help of the list, I have a well functioning wireless lan rig. In case someone else in my positition is reduced to searching list archives, I'll outline how things went. I've got a D-Link DWL-650 11Mbps 802.11b pcmcia wireless lan card an ipaq 3660 running linux (Familiar 0.4), talking to my gateway (Debian 2.2) with an Aironet 4800 pcmcia-in-a-pci-card rig. Firstly, to clarify some issues around the DWL-650; it is a stock prism2 chipset 16 bit pcmcia card, of a fairly standard variety. It's not a wavelan, or cardbus. In stock linux, it doesn't appear to work with the (obsolescent) wvlan_cs driver, but apparently does with the orinoco/hermes driver (the replacement for the wvlan_cs). However the orinoco/hermes drivers don't work on Linux/ARM, due (apparently) to aligned-ness issues. My goal was to have working 802.11b in ad-hoc/IBSS mode to the various wlan clouds in my commuting-life. The only working solution appeard to be the Linux WLAN Project's[1] wlan-ng. The wlan/wlan-ng projects are an implementation of the 802.11b standards for Prism2 based cards. The wlan-ng drivers are the newer 11Mbps ones, whilst the older wlan ones are more mature, but only support 2Mbps. (As as interesting aside, the wlan/wlan-ng drivers support all manner of neat stuff, such as 'access point' functionality, promiscuity, and other neat tricks.) The wlan-ng drivers as yet have only unofficial patches for ad-hoc support, which I obtained from the wlan-ng mailing lists. (The turnover in patches is high, so check the mailing list to see where support is at - it may well be in the stock release now...) I'm runing linux-wlan-ng-0.1.8-pre13 with patches. I set out with familiar 0.4, using the stock 2.4.3-rmk2-np1 kernel. I set up the cross-compiler toolchain, (built a few things to test), and then configured a 2.4.3-rmk2-np1 kernel source tree and pcmcia-cs-3.1.29 tree to build wlan-ng against. The trick to getting wlan-ng to build and work on the ipaq, appears to be some mangling of the pcmcia voltage detection stuff. I read elsewhere on the mailing lists[2] that this is due to the Ipaq doing some auto-voltage-fu, and thusly confusing things that try to set it manually. Whilst not solving the problem, by mangling the code path[3] so it doesn't head off the wrong way, you can get a working build. Next, I discovered that the DLink shipped firmware lacked adequate ad-hoc mode support (apparently the windows drivers do some serious kludging to make it go), and also discovered that the version available from the dlink site was also inadquate. In a leap of faith, I 'upgraded' the card with a smc firmware[4] of the appropriate version, using the windows utility[5]. From there, it was a simple case of configuring /etc/pcmcia/wlan-ng.opts to set SSIDs and the like, insert the card, and bob's your uncle. There's still a few error messages here and there, but nothing that impairs functionality. Now I'm happily listening to streaming mp3, browsing, and battling pine with a stylus :) Adam [1] http://www.linux-wlan.org [2] http://www.handhelds.org/pipermail/ipaq/2001-May/006717.html [3] linux-wlan-ng-0.1.8-pre13/src/prism2/driver/prism2sta.c, line 2936 and friends [4] http://www.smc.com/drivers_downloads/library/S10008C3.zip [5] http://www.smc.com/drivers_downloads/library/WinUpdate_OEM_1.1.zip On Saturday 27 October 2001 10:22, you wrote: > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > On Saturday 27 Oct 2001 5:01 pm, you wrote: > > Hello everyone, > > > > Just wondering if anybody has experience with any 802.11b products under > > Linux?
