Title:
When trying to connect to an AP using an ASUS PCE-N15 wireless card,
the kernel prints "warn_slowpath_common"
Status in “linux” package in Ubuntu:
Invalid
Bug description:
My wlan1 interface relates to a ASUS PCE-N15 card ("RTL8188CE
802.11b/g/n WiFi Adapter", managed by the rtl8192ce kernel module).
I have this /etc/network/interfaces config for this card:
iface wlan1 inet dhcp
wireless-essid $ESSID
wireless-key $WEP-key
When I tried to connect using "sudo ifup -v wlan1", the connection to
the access point was not established.
Using dmesg, I see some warning related to "warn_slowpath_common".
Could not reproduce these messages though ...
