Coming back to this issue, I just don't like the feeling of defeat. I have tried various live cds, mostly rescue ones because of some silly things I've done, and I can always get wireless to work with ndiswrapper and the sis163u.inf driver. I am now wondering if its got something to do with the speed. My router definitely thinks the laptop is there (with slackware 12.1, kernel 2.6.26.3, and ndiswrapper 1.53 compiled against the aforesaid kernel):

Code:
01.09.2008 13:05:47 WLAN-Station abgemeldet: Rechnername: PC-da6ffe, MAC-Addresse: 00:30:05:DA:6F:FE. (W001)

01.09.2008 12:36:52 DHCP ist aktiv: [09/01/08] [12:36:52] [WLAN] [00-30-05-da-6f-fe] [00:30:05:da:6f:fe] [192.168.1.102] [255.255.255.0] [] [192.168.1.1] [-1]  (H001)
Bottom line is me logging on with dhcpcd wlan0, upper line is me shutting down.

From my desktop I ran nmap:

Code:
[root@localhost us]# nmap -sS -O 192.168.1.102

Starting Nmap 4.53 ( http://insecure.org ) at 2008-09-01 12:56 CEST
All 1714 scanned ports on 192.168.1.102 are filtered
MAC Address: 00:30:05:DA:6F:FE (Fujitsu Siemens Computers)
Too many fingerprints match this host to give specific OS details
Network Distance: 1 hop

OS detection performed. Please report any incorrect results at http://insecure.org/nmap/submit/ .
Nmap done: 1 IP address (1 host up) scanned in 39.786 seconds
[root@localhost us]#
It took a long time (39 seconds), but I think it found it. Could the multiple fingerprints be something to do with me having had a cable plugged into it earlier this morning? - dhcpcd gives me a different ip then, because the mac address is different.

I just wondered if anyone out there has had any ideas since March...

I tried setting the speed like this:
iwconfig wlan0 rate 11MB auto

but iwconfig still reports a speed of 54Mb/sec.

It's just kind of frustrating

That is possible. If the card isn't running at the same speed as the network, they don't communicate. Now with that said, a properly functioning network will negotiate with a card to find a speed they can use to communicate.

Did you get an error from that because I'm not sure the syntax is quite right. Try this:

iwconfig wlan0 rate 11M

I don't think so. If I remember correctly, all nmap is doing here is looking to see what services are being run on the target computer and that shouldn't vary between wired and wireless. I think all this result means is that based on the services nmap found, it can't decide what OS the host is running.

However, one thing to keep in mind is that on some machines having both the wired and wireless interfaces up and functioning at the same time can cause problems. If you bring up the wireless interface, be sure to bring down the wired one.

As for new ideas, I'm afraid not. If all the other information you posted is still true, I'm still stumped. From what you posted before, this should be working just fine.

Tried that and it still didn't work. I couldn't tolerate pclos so I ended up buying a stick - (Edimax 7318Ug with a Ralink RT73 chip set which runs straight out of the box in case anyone's interested) and I'm back with my favourite slackware. But it is a puzzle though, isn't it.


thanks for your help

Thumbs up Success with slackware 13!

I have just installed slackware 13 on a spare partition of my misbehaving laptop. Just for the sake of completeness I went through the motions of installing ndiswrapper and the now familiar steps of setting up my wlan card. And much to my surprise and joy, it worked! Just like that. I feel very relieved and also puzzled, but mostly relieved. Its the huge smp kernel that came with slack. Now I just have to persuade the rest of the family that kde4 is ok, and they really don't want to use those applications that depend on pyqt3.

sighs of relief
