Can't get wifi working, Orinoco on IBM T22 laptop


Can't get wifi working, Orinoco on IBM T22 laptop

I have a classic Orinoco gold card (rebranded 2Wire) and an old T22. The card works fine under Knoppix livecd, but i've not been able to get it running under Ubuntu 5.04 (Hoary). (Haven't upgraded to Breezy bc i can't risk downtime right now -- I'm nowhere near linux expert.)

I can see the drivers in lsmod:

Code:
orinoco_cs              8968  1
orinoco                38284  1 orinoco_cs
hermes                  7936  2 orinoco_cs,orinoco
pcmcia                 21380  5 orinoco_cs
pcmcia_core            53568  3 orinoco_cs,pcmcia,yenta_socket
And dmsg doesn't appear to have any wifi errors:

Code:
eth1: Station identity 001f:0001:0008:002a
eth1: Looks like a Lucent/Agere firmware version 8.42
eth1: Ad-hoc demo mode supported
eth1: IEEE standard IBSS ad-hoc mode supported
eth1: WEP supported, 104-bit key
eth1: MAC address 00:02:2D:B6:0C:59
eth1: Station name "HERMES I"
eth1: ready

Here's my ifconfig (eth0 is my wired connection):

OK, that looks fine. You're associated with the AP and getting a good signal.

Instead of running the ifup script, try dhclient or pump (not sure which on Ubuntu) to pull an IP address.

Yes, great! dhclient works ... well, sort of. I have connectivity for a while, but then it seems to stop working. Mhrrr. I'm sitting right next to an airport base station... Can you give me any sense of the big picture here? Where should dhclient be getting called ... I don't really have a clue about how to debug this...

The command ifup isn't really a command, it's a script. Open it up to see what commands it's calling. Not sure how Debian distros save network parameters or where the ifup script is invoked, though. Sorry.

Odd that it stops working. Check /var/log/messages to see if there's any clue of what's happening. Are there a lot of other wireless LANs in near you? Maybe you're too close to the AP (seriously). I've seen folks report that if they are right next to the AP, things don't work. Not likely, but a thought.

Well, a step closer anyway... is there some way to watch what's actually going on in terms of network traffic?

There's just one network right here, and i'm not physically on top of it... Btw, on ubuntu ifup is a binary -- according to the man, it's a wrapper for low level routines such as ifconfig and route.

Thanks for your help...

OK, I learned something new. I've not fooled much with Debian. My assumptions about ifup came from SuSE and RH.

I should stick to answering questions about Slackware, I guess.

I suppose you could run Ethereal to see what's happening in terms of data packets, but that seems like using a hammer to swat flies. Maybe someone can suggest a better tool.
