Hi, not sure if network thread or slackware.

Sometimes Toshiba M55-S1001 laptop loses connection to WAP. Not sure how to get it back without rebooting.

Networking is all there just can't communicate with WAP.

Slackware 13.1.0/2.6.33.5 and up to date.

I have same setup on A21m ThinkPad and it doesn't lose WAP when Toshiba does.

Is there a way to re-establish WAP connection without rebooting?

Can provide additional info as necessary.

thanks

Try this
and yes, additional info would be useful, if you want to fix/find out what causes it.

In addition to the above, you can also specify your interface like this:
I've only had disconnection problems with gui network managers (e.g. wicd, NetworkManager) and you can reconnect using those programs too.

You also might be able to get away with "dhcpcd" assuming everything is setup as desired.

Forgot to say, the networking on the toshiba which loses the WAP can run for weeks/months without losing connection to the WAP.

I've used the following for couple years in /etc/rc.d/rc.local on both the thinkpad, laptop without any problem, and the
toshiba which has WAP disconnect problem.

/usr/sbin/wpa_supplicant -B -c/etc/wpa_supplicant.conf -iath0
sleep 5
/sbin/ifconfig ath0 up 192.168.0.199
/sbin/route add default gw 192.168.0.1
/sbin/iwconfig ath0 rate 54M

As I said before when toshiba loses the WAP the thinkpad does not.

I've tried to restart doing
/sbin/route del default gw 192.168.0.1
/sbin/ifconfig ath0 down
killall wpa_supplicant

then all the rc.local lines above, when I can't get connected and restart wireless, ifconfig shows ath0 has ip and mac address, iwconfig does not show connection to WAP.

What kind of other additional information would be helpful?

Next time Toshiba laptop loses connection to wireless access point I'm going to turn off the wireless access point then turn it back on, then restart the wireless on the laptop to see what happens.

Will post back whenever that happens.
