I have a weird problem of connecting to a wireless network. I am connecting to a network named "C-202" with WPA-Personal. This network shows up in the scan results some time and won't show some time. I can't really figure out a pattern from this. Sometime the network won't show up. It may work after few restarts.
I was using
Wicd initially and thought this was the problem with wicd. Uninstalled wicd and started using
NetworkManager, but the problem persists. Then I tried the scan directly on terminal like
iwlist wlan0 scan
This shows a list of networks available, but not the one I want to connect. I can connect to that network from other computers, but not from this.
Interestingly, when I change the SSID from
C-202-New, it shows up in the list and I can connect. The connection works for few days and the problem starts again. Changing the SSID again will fix it. It looks to me like some cache is messing things up.
$ lspci -v | grep wireless 03:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02) Subsystem: Intel Corporation PRO/Wireless 3945ABG Network Connection Flags: bus master, fast devsel, latency 0, IRQ 44 Memory at d8000000 (32-bit, non-prefetchable) [size=4K] Capabilities: <access denied> Kernel driver in use: iwl3945
I have no clue on how to debug this issue. Can anyone help me to debug and fix this issue? Any help would be appreciated
