Im having a strange problem with my wifi. Its very slow when ever my laptop running ubuntu 13.04 is connected to it.
My setup: asus n16 router running asuswrt-merlin fw (have also tried with dd-wrt), wifi is secured with wpa2 personal.
Server is running ubuntu 13.04 and is connected to the router by cable.
When I'm copying a file from the server to my android tablet via wifi im getting speeds between 20 and 40 kb/s when my laptop is connected to the same network. As soon i disconnect the laptop the transfer speed to the tablet goes up to about 3mb/s.
When i reconnect the laptop the speed drops again.
Any ideas why this is happening?
