My Wifi connection to my university wifi, which is a PEAP/WPA2/mschapv2 network with no offered certificate, drops constantly. It has a weird pattern where earlier in the day it drops fairly rarely(~every 30 minutes), but as the time spent on the device increases, it drops more and more until times when drops occur every 2-3 minutes, and eventually it becomes basically impossible to connect, at which point I try turning Networking off/on, which sometimes works, or deleting and recreating the saved network, which often works, but both of these fixes still just give me a few more minutes. Rebooting tends to "reset" the issue back to a point where it doesn't drop as often, but again it decays with time.
I'm currently on Elementary (Ubuntu 12.04), but I've run sudo apt-get upgrade and dist-upgrade, so I imagine that everything is up to date. Additionally, I experienced the exact same problem a few weeks ago on 13.04.
Fixes I've already tried:
(1) Setting IPv6 connection to "ignore" in the network manager dialog box. Doesn't seem to do anything.
(2) Setting system-ca-cert=false in /etc/NetworkManager/system-connections. The line seems to always be removed and I've never seen system-ca-cert=true in there.
Here's my systems-connection file for reference:
[ipv6] method=ignore [connection] id=ssid_name uuid=xxx-xxx-xxx type=802-11-wireless timestamp=1382910760 [802-11-wireless-security] key-mgmt=wpa-eap [802-11-wireless] ssid=ssid_name mode=infrastructure mac-address=00:23:15:AE:F4:F0 security=802-11-wireless-security [802-1x] eap=peap; identity=username phase2-auth=mschapv2 password=mypassword [ipv4] method=auto
and here's some info about my wireless card:
description: Wireless interface product: Centrino Advanced-N + WiMAX 6250 [Kilmer Peak] vendor: Intel Corporation physical id: 0 bus info: pci@0000:02:00.0 logical name: wlan0 version: 5f serial: 00:23:15:ae:f4:f0 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=iwlwifi driverversion=3.2.0-54-generic firmware=18.104.22.168 build 33926 ip=10.164.93.55 latency=0 link=yes multicast=yes wireless=IEEE 802.11abgn
Any way I could fix this? It's killing me and basically making using ubuntu impossible at my university after being a dedicated user for 6 years.
