View Full Version : [ubuntu] My internet keeps dropping randomly.

January 4th, 2010, 07:42 PM
I'm using Ubuntu 9.04 64 bit on an Asus laptop and the wireless connection disconnects randomly for a while and keeps searching for the signal. When it finds it I have to put in my WEP key again to get it to connect sometimes only once or sometimes 2 or 3 times. This is getting quite annoying. What can I do to stop this?

You could make it connect automatically, doesn't solve the problem but is not as inconvenient at least.

It does connect automatically when I turn on the laptop. The problem is having it staying connected.

Had that happen to me. It was an issue with cordless phones close to the same bandwidth. Try changing the router channels until it gets better. Hope this helps.

I do have cordless phones down and upstairs so that might be it. How do I change the router channels?

Please post the output of

as soon as you are connected. It may be signal strength (or interference as stated earlier). What is the make/manufacturer/model of the router that you are connecting to ? Can you connect to it via a cable (in order to change the channel) ?

What kind of router do you have? If it's a linksys you'll have to log into it and change it in the wireless settings. The RSM wireless band only has three channels that don't overlap, 1, 6, and 11.

I would recommend changing the router to use channel 1 and see if that helps anything. It'll rule out the phone interfering with the signal.

*Knocks on wood* I have not had it disconnect today so far. ^_^ Its Verizon.

Signal (link) quality seems a little poor. How far away is the Verizon router/source ? Are you using the PC in a different room ? If you can do it an external aerial for the wireless may help at either the router or PC end.
Take a look at this (http://www.overstock.com/Electronics/Eforcity-2-pack-Wi-Fi-Wireless-Antenna-Router-Signal-Booster/4486174/product.html?cid=133635).

I'm usually 2 rooms away when downstairs or upstairs in my room when it happens. I tried disconnecting the wireless phones from the receivers and that seemed to help a bit or maybe its just a coincidence. What if I aimed the antennae to the direction I am? Right now IIRC its to the right and i'm always to the left of it.

Got 5 disconnections in a row last night. I looked up wireless signal dropping in Ubuntu 9.04 on google and it seems a pretty good amount of people have this and its a bug. I hope it gets fixed in the next release.
