Can't connect to one wifi network, keeps asking for password

Question

Here's the relevant syslog stuff: http://pastie.org/9405812

Here's the output from the wireless-info script: http://paste.ubuntu.com/7821949/

My wifi works well in general, I only have problems with this network. The router is a netgear wnr1000v2-vc. It may be possessed.

Things I've tried: Disabling power management, reboot, satanic ritual, rebooting a second time, giving up, deciding not to give up after all, posting on ask ubuntu

Solution

First remove all special characters from the network name.

Now, check the settings in the router. WPA2-AES is preferred; not WPA and WPA2 mixed mode and certainly not TKIP. Second, if your router is capable of N speeds, I have better luck with a channel width of 20 MHz in the 2.4 GHz band instead of automatic 20/40 MHz.

I also have better luck with a fixed channel, either 1, or 11, rather than automatic channel selection. After making these changes, reboot the router.

Next, I recommend that your regulatory domain be set explicitly. Check yours:

sudo iw reg get

If you get 00, that is a one-size-fits-all setting. Find yours here: Country Code Then set it temporarily:

sudo iw reg set IS

Of course, substitute your country code if not Iceland. Set it permanently:

gksudo gedit /etc/default/crda

Use nano or kate or leafpad if you don't have the text editor gedit.

Change the last line to read:

REGDOMAIN=IS

Proofread carefully, save and close the text editor.

Next, I'd set IPv6 to Ignore in Network Manager: IPV6 setting This example is for ethernet, but you want wireless.

I tried, it didn't work.

After deleting that connection. Reboot. And then try connecting to that connection again. I had to reboot last time in order for it to work.
