Most of the routers use that combination as default, and that is not optimal.
Please try changing it to pure WPA-PSK with CCMP (AES). No TKIP or the WPA+WPA2 mixed mode. Reboot the router after saving the changes and retry connecting.

If it still fails, please post the outputs of :

Code: Select all

grep [[:alnum:]] /sys/module/ath9k/parameters/*
dmesg | egrep -i 'ath9k|80211|wireless|wifi|switch|network'

the second ping error seems to be clearly firewall related:
ping: yahoo.com: Temporary failure in name resolution
the first error is less clear, but maybe also firewall:
ping: yahoo.com: Temporary failure in name resolution

Plausible, but disabling firewall

Code: Select all

iptables -F
iptables -X
iptables -t nat -F
iptables -t nat -X
iptables -t mangle -F
iptables -t mangle -X
iptables -P INPUT ACCEPT
iptables -P OUTPUT ACCEPT
doesn't help. (Also, it works ok when I switch to the wired connection.)

Re: wicd says wifi connects but no Internet [SOLVED]

It turns out it was indeed iptables. The code above, which supposedly disabled iptables, didn't do the job sufficiently. Revoving the iptables.up.rules file from /etc did, and I've rewritten iptables.up.rules so it's no longer a problem.
