WI-Fi random disconnected from AP [SOLVED]

Post by GotuX »

Hi, I have a problem whit wifi, this is randomly disconnected from AP, same issues with the internal INTEL 3945 and with usb dongle RTL8192CU.
This is the dmesg output when disconnected:

Code: Select all

[ 1942.216098] ieee80211 phy0: wlan0: No probe response from AP 10:0d:7f:3c:74:92 after 500ms, disconnecting.
[ 1942.399870] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready
[ 1945.702913] wlan0: authenticate with 10:0d:7f:3c:74:92
[ 1945.704638] wlan0: send auth to 10:0d:7f:3c:74:92 (try 1/3)
[ 1945.706505] wlan0: authenticated
[ 1945.707074] wlan0: associate with 10:0d:7f:3c:74:92 (try 1/3)
[ 1945.709733] wlan0: RX AssocResp from 10:0d:7f:3c:74:92 (capab=0x11 status=0 aid=8)
[ 1945.710950] wlan0: associated
[ 1945.710993] IPv6: ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready

then I need to power cycle the wifi to restore connection.
On FreeBSD and Win10 there's no issues.
Any idea?
How I can investigate?
Thanks

If it doesn't work, you might want to change to wicd. Even thought the changes initially appear to work over time NetworkManager proved to be unstable on my home network. I finally just gave up and switch to wicd.

So...
I solved the problem but only mixing both suggestions.
Setting dhclient as default service, the network is stable but sometimes at the startup the wifi is unavaible in NetworkManager applet...sincerly i've not investigated anymore.
So i've installed Wicd and the connection is stable and the configuration was simple.
Thanks a lot for the tips and for express support.
Stefano.
