802.11 a/b/g wireless LAN on RedHat-SL

[serleon]

Hi,
i've got an ACER 5630 and a Scientific Linux (RedHat 5 kernel) running on it.
Is there any possibility of making the wireless internet work?
Thanks

[valemon]

please post the output of "lspci -v" and "iwconfig" commands.

[serleon]

Thanks for the answer...

both of them are: commands not found

what to do...

[valemon]

run as root, enter su, your password and then type the commands

[serleon]

nop... i did first as root, then as su.. nothing..
Weard, that is a classical Linux command

[valemon]

Well, iwconfig is part of the wireless tools for linux. But lspci should work... try getting root privileges by typing su -

[serleon]

Got it...

lspci -v

iwconfig

lo no wireless extensions.

eth0 no wireless extensions.

sit0 no wireless extensions.

Your are using the intel 3945abg adapter, it should be easy to get it working. Take a look here for firmware and instructions. Maybe with an other distro it would work out of the box. Post back if any problems occur

[serleon]

many problems arose... new kernel and stuff... working fine now
thanks a lot valemon!

[valemon]

Glad to hear this. Have a good time with wireless internet
