Cannot find wireless network anymore after reboot last night
Hope someone can help me relatively soon. I have been having a similar issue.
Last night everything was working perfectly fine. This morning when I booted up BT5, wicd could not locate any wireless networks. I have tried just about everything I can think of.
dmesg does not bring up any issue with my wifi card. I am using a Broadcom Corporation BCM4311
The output of ifconfig is (for wlan0):
Link encap: ethernet HWaddr 00:19:38:24:26:c9
UP BROADCAST MULTICAST MTU:1500 METRIC:1
RX packets:0 erroors:0 dropped:0 overruns:0 frame:0
TX packets:0 erroors:0 dropped:0 overruns:0 frame:0
collisions:0 txqueuelen:1000
RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
The output of iwconfig is:
IEEE 802.11bg ESSIDff/any
Mode:Managed Access Point: Not-Associated Tx-Power=20 dBm
Retry long limit:7 RTS thrff Frament thrff
Encryption keyff
Power Managementff
I have run ifconfig wlan0 up multiple times. I have tried running 'dpkg-reconfigure wicd' and 'update-rc.d wicd defaults' to set it back to defaults.
I am wondering if maybe I have something blacklisted by mistake and it is interfering, yet I am not too familiar with /etc/modprobe.d
wicd-gtk displays no errors that I can see. Anybody have any other tips? It was fine last night....a simple shut down screwed this up..
Do you have other wireless devices that you have used to test your router/access point? If not and if the computer is portable, test it at a location with public wireless.
It's important to isolate the source of the problem before you tear your hair out with software. True, it's unlikely that your router/access point has turned turtle, but, if it has, no amount of software troubleshooting on the computer can fix the problem.
I've had situations where a wireless connection held until it was broken, as by a reboot, and then the device could not reconnect. The problem was solved by rebooting the router. The router kept existing connections, but would not accept new ones.
If you have a laptop, it's possible that there's a button anywhere which enables and disables wifi on the laptop. Pressing this button by accident is one of the most common causes for unexplainable wifi-problems.
I have enabled and disabled wifi multiple times with the on/off button. I know it is on now b/c the card is recognized in iwconfig and dmesg doesnt bring any more error up anymore.
