Wpasupplicant disconnects because of inactivity (reason = 4):

#define WLAN_REASON_DISASSOC_DUE_TO_INACTIVITY 4

This can be a number of things, including a kernel issue. Do you have access to the wireless access point? Can you control it, or can you see what happens on its side, in the logs, when you get disconnected?

[Adrian Suarez (asuarez985)]

Yes, I do have access, control and viewing capabilities. Attached is the log.

Another thing I wanted to point out is that this issue did not occur with 12.04 amd64. Problem started after a fresh install of 12.10 amd64.

I've had the same issue since installing Kubuntu 12.10. I've had no issues with the 12.04 release or the 3.2.0 kernel. I've tried everything from removing power saving features, installing various compat-3.X drivers, and kernel 3.6.2. I get the same error messages WPA Supplicant reason 4.

[robbie (roberto-tomas-cuentas)]

Im also having this problem, and have disabled ipv6 and forced a static route and removed isc-dhcp-client.

[Tim Griffiths (bullwinklescousin)]

I've turned off mixed WPA & WPA2 on my router which seems to have helped. Not a true fix, but works for me as long as I can't remember what device I turned it on for compatibility. I'm perusing the WPA_Supplicant source, but it's like looking for a needle in a warehouse full of haystacks.

[Adrian Suarez (asuarez985)]

Please click on This bug affects you if it does. That way the janitor will change the status to confirmed. Thanks.

Having the same issue on Asus EeePc 1001P, Ubuntu 12.10 32-bit. Will try to change WPA mode to WPA2-only on router.

[Pavlo Shchelokovskyy (pshchelo)]

After trying many different things as switching between WPA-only, WPA2-only, WPA-WPA2-mixed, disabling UPnP and WPS, and downgrading to Ubuntu 12.04 I still had this problem. Then I tried another router - and everything works fine now, with WPA-mixed mode and Ubuntu 12.10, so luckily for me this problem is solved. If it helps anyone, the problematic router was Belkin Basic Wireless Router F7D1301 v1 and the working one is Sitecom WL-160.

This issue is not linked to any Router Model or for that matter any settings like WPA/WPA2 or IPV6 or any other router / Ubuntu kernel version, I connect to 15 diffrent WiFi routers from time to time and have faced this issue with my hardware and there is no solution that I have come across.

I like Ubuntu and the only thing that has worked for me is downgrading to the version where my hardware is compatiable.
