Hi there,
I'm having issues with wifi, many logs can be found here
https://gist.github.com/alex88/bdfc6907 ... -more_logs
basically it loops on these logs
Code: Select all
wlan0: Trying to associate with _hidden_mac_ (SSID='wifinetwork' freq=2462 MHz)
wlan0: Associated with _hidden_mac_
wlan0: WPA: Key negotiation completed with _hidden_mac_ [PTK=CCMP GTK=TKIP]
wlan0: CTRL-EVENT-CONNECTED - Connection to _hidden_mac_ completed [id=0 id_str=]
wlan0: CTRL-EVENT-REGDOM-CHANGE init=COUNTRY_IE type=COUNTRY alpha2=US
wlan0: CTRL-EVENT-DISCONNECTED bssid=_hidden_mac_ reason=0 locally_generated=1
wlan0: CTRL-EVENT-REGDOM-CHANGE init=CORE type=WORLD
wlan0: CTRL-EVENT-REGDOM-CHANGE init=USER type=COUNTRY alpha2=US
yesterday I got it working by removing the region setting from wpa supplicant and using `iw reg set WORLD` just to set an unknown region and it was stable for a while, today I've the same issue again.

What WiFi adapter are you running? Are you using one of Mr Engman's drivers for it? Have you disabled power saving mode?

It's a raspberry PI 3, `lsusb` shows just
Code: Select all
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp. SMSC9512/9514 Fast Ethernet Adapter
Bus 001 Device 002: ID 0424:9514 Standard Microsystems Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
I have raspbian minimal image, also it seems a problem with the channel, with a lower channel number the problem doesn't seems to happen all the times as with channel 11.

Try upgrading to Raspbian 2016-11-25. Or bringing your current system up to date with
sudo apt-get update && sudo apt-get -y dist-upgrade && sudo reboot

Then your problem is either broken hardware or too many obstacles (like walls) between your RPi and your WiFi access point.

However for different channels it works perfectly, and the AP is like 30 cm away

Then it's co-channel interference from your neighbours. Pick a non-standard channel (not 1 or 11).

The only wifi networks available are the one of our office and the one of the repeater (which are on the same channel because of the repeater uses the same channel as the main network)

Why? Spread things round the spectrum, the client machines can automagically switch channel to the one that has the best signal. Run something like ISSIDer to take a look at the crowded channels (you will be amazed at the number of WiFi stations that are broadcasting within range).

Because on the repeater there are no options to change the channel while in wisp mode.
And as I told you, there are only 2 wifi. `iwlist scan` in fact shows just 2 cells

Code: Select all
CTRL-EVENT-REGDOM-CHANGE init=COUNTRY_IE type=COUNTRY alpha2=US
