I can not connect to some Wifi on my Asus eee-PC 1015PX netbook.
After some experimentations, I found that it can not connect to channels>11 (I live in France, where channels 12 and 13 are allowed. See https://en.wikipedia.org/wiki/List_of_WLAN_channels#2.4.C2.A0GHz_.28802.11b.2Fg.2Fn.29 ).
It has a Broadcom BCM4313 chipset and runs Ubuntu oneiric 11.10 with all updates. The driver is the open-source one : brcmsmac.
I can connect to Wifis on channels <=11 with no problem.
If I configure my Wifi on channel 13, it is correctly detected on another laptop using iwl3945 driver, and I can connect to it. But it does not appear in the list on the netbook.
If I switch to channel 5 for example, I can connect and use the Wifi.
I tried the workarounds proposed in similar issues :
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/836133
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/288401
None of them worked. I still can not connect. That's why I opened a separate issue.
Here is the detail :
With default config :
iw reg get => US
iwlist wlan0 channel => only the first 11 channels
Wifi on channel 13 not detected
With iw reg set FR :
iw reg get => FR
iwlist wlan0 channel => all 13 channels
Wifi on channel 13 detected, but cannot connect to it (asking the password again and again)
After a reboot, the setting is lost and comes back to the default config
With a file /etc/modprobe.d/regdom "options cfg80211 ieee80211_regdom=FR" and "options lbm_cw_cfg80211 ieee80211_regdom=FR" and a reboot :
iw reg get => 98
iwlist wlan0 channel => only the first 11 channels
Wifi on channel 13 not detected
With the file /etc/modprobe.d/regdom and iw reg set FR :
iw reg get => 00
iwlist wlan0 channel => only the first 11 channels
Wifi on channel 13 not detected
