Hi guys. I have a weird problem. Have been using wifi on my Linux Mint 14 laptop for a long time and had no problems. Two nights ago all of a sudden it is not picking up my Vodafone B2000 router anymore. It is picking up the neighbours Dlink however. The router is working fine as my phone still picks my router. I have tried changing the SSID and the key to see if that does the trick not it did not help. I also booted from a live CD but on their it still does the same thing.

Do you guys have any advice?
 
Maybe change the router from 2.4 to 5ghz?

Or 802.11G to 802.11N which the the card doesn't support?

Changed to Channel 13 maybe Which sometimes doesn't work with some cards.

Ok....will give that a go. Not sure how exactly but sure I can find it in the router setup page. Just weird that it was working fine the one day, and the next boom....nothing. I have not changed anything on the laptop or router side.

Here is my settings. What should I change? Just the channel as 802.11 seems to be on multimode already? What channel must I use? Seems it is currently on 13
 
Your current channel is 13. That's your problem.

Switch your country so that it doesn't include 13.

Or manually set it to 1, 6 or 11. If you can find out what channel your neighbor is on with a wifi scan tool you can even set it to any of the above furthest away from his.

Since your auto is 13 I suspect he is probably on 1 or 6 so best to start with 11.

While you are there set your transmit power to 100% and improve your wireless signal.

Also set your Wireless Encryption to AES only if you have the option instead of TKIP and AES.

You can make the security WPA2 only as well if you like. The less overhead the better.

YAY!!!! It worked!!!! Posting this from laptop. Thank you so much! I wonder how it changed to channel 13 as I certainly did not do it. Does it maybe change between channels automatically seeing that it was on "auto" I think?

Anyway.....thank you again. I am so relieved now. Thought my wifi card in laptop was bombing out or something. Gosh, so relieved now! Thank you thank you thank you.
 
Yeah auto jumps around on each reboot.

And because your country is Romania it has Channels 12 and 13 which isn't officially supported in SA.

Well....thank you again. I was about to reload my laptop. Thank goodness I had the good sense to ask here first. Should not change now again cause I set it manually I assume.

Thanks again
 
Sometimes with routers, just restarting them sorts out this issue. I often have it when I have some devices that are connected and others that wont. Restarting the router sorts this out.

That's not solving the problem, just ignoring it.

Setting the channel manually solves it permanently. No reboot required.
