I have a Thinkpad T23 with builtin WLAN adapter.
lspci: 0000:02:02.0 Network controller: Intersil Corporation Prism 2.5 Wavelan chipset (rev 01)
I'm running Ubuntu 5.10 (kernel 2.6.12-10-386) which autodetects the card and loads the modules hermes, orinoco and orinoco_pci.
Basically this setup works, but after a while (5-60 min) it gets unstable. That means, it looses the connection.
This happens even with perfect signal and it happens in different networks.
Today I booted Gentoo a 2006.0 live-CD to see if it also happens with another distro. Same behaviour there (kernel 2.6.15)
I wonder about this because Prism 2.5 seems to be well supported in Linux of what I've read.
Of what I understood it should be possible to use other drivers.
I can't figure out how to do this. I tried to unload the 3 modules mentioned above and to load the module hostap_pci, but nothing happend. Which alternative drivers exist and how do I load them?
Also I've read that the firmware version has big influence. How can I find out which version I have / how to update it?
Thanks for every advice!
EDIT:
this is what dmesg outputs when the problems begin:
