I saw that your problem was with your Linksys router and not with the WLAN
card. This was for information only ( for others, not just you will read
this newsgroup thread). Please accept my apology for any misunderstanding.

It might be just fine, some have found that the default sound
configuration in /etc/modprobe.conf be a problem however. By adjusting the
sound configuration to what ALSA suggested configuration sometimes fixes
the problem.

The default sound levels are muted by default, see;
http://www.exocore.com/technologies/linux/i810/i810-6.php3
http://www.linuxfromscratch.org/blfs/view/stable/multimedia/alsa-utils.html

Some have found a 'fix' or 'workaround' which is to (as root) modify
/etc/rc/d/rc.local ( ALSA suggest configuration independent) and add
something like (the next two lines below);

# Restore the sound volume levels for ALSA

/bin/aumix-minimal -f /etc/aumixrc -L >/dev/null 2>&1;

Then create the /etc/aumixrc file (sample below);

vol:75:75:P
pcm:75:75:P
speaker:75:75:P
line:75:75:P
mic:75:75:R
cd:75:75:P
igain:75:75:P
line1:75:75:P
phin:75:75:P
video:75:75:P

Adjust the default sound levels (above) to suit your comfort level(s).
