Ubuntu: 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:1

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.


Solution:2

Try delete that wifi connection from the Network Connections list (wifi icon).

Then restart wireless with sudo service network-manager restart


Solution:3

add this option in kernel drivers settings

echo options iwlwifi 11n_disable=1 | tee -a /etc/modprobe.d/iwlwifi.conf  

Then restart the system this must fix wifi problem.
