Wireless AP problems

I've just setup FreeBSD 8.1 as a Wireless AP with ipfw, dnsmasq and squid.

Everything works fine for a while but after two hours or less it becomes slow and the connections are lost.

I don't know what to do [cmd=]netstat -i[/cmd] shows a lot of errors:

fxp0 is the Internet connection, configured with DHCP, ral0/wlan0 is a Linksys card in hostap mode, the clients can connect get an ip and browse the web.

I don't know if I did something wrong or I am missing something in the firewall for now is set to "OPEN" in rc.conf

Or maybe is the wlan0 config, in short I don't have any idea on how to fix this.
 
If it works for over 2 hours before having any issues, I doubt it's related to configuration. It would help a lot if you can narrow this issue down as much as possible. For example, does that issue also occur if there is only one client, without any encryption, connected? Does it happen after exactly 2 hours, or is it kinda random or connected to how much traffic is going on?
 
Check the wireless card's manufacturer's website/forums for possible problems with your card, especially if the problem occurs after 2 hours consistently -- which means it could be a firmware issue.
