ra0 wireless interface disappeared!

[paradigm_shift]

i installed fglx driver for ATI radeon 9700 video card. this involved recompiling kernel source for 2.6.11.

before eth0 eth1 ra0 detected automatically but now dmesg says it detected eth0 eth1 but ra0 has disappeared! lsmod reveals that agpgart which is video driver is correctly loaded but rt2500 module is not present when i did modinfo. i know that before fglx driver install rt2500 module was loaded now system says it is not present! how do i recover kernel and/or init settings to previous original knoppix?

plz help. :(

i think i can configure rt2500 driver if i can install rt2500 module or recover it or repair its configuration so lsmod detects it there. i don't have internet connection in my laptop so i have to do it without it.

i'm going to try copy rts2500* from / in knoppix live cd into hd installation filesystem. what else do i have to do?

[paradigm_shift]

so i managed to install rts2500-base and rts2500 versions 1.1 i think. is that sufficient to install rts2500 modules upon boot?

solution found!

to install stuff that has to compile to kernel source then install another kernel source and header files using apt-get (or indirectly using kpackage for GUI) and do the job in the other kernel then come back to your knoppix kernel for correct hardware detection. for me, i installed kernel headers 2.6.11-1 whereas knoppix ships with 2.6.11. i also installed kernel image 2.6.11-1 and booted to 2.6.11-1 and successfully installed vendor-supplied video card driver, which required header files (2.6.11 don't have header files as deb package). then i was surprised to find that in 2.6.11 video card was succssfully configured!

another note: i discovered a very good program for configuring rt2500. use apt-get to install RaConfig2500 by installing package called rt2500 and other depended packages (should be automatic if you set up apt-get correctly using net connection as source).

happy knoppixing!
