Hello. I am using the a Plugable USB 2.0 Wireless N 802.11n 150 Mbps Nano WiFi Network Adapter to connect the internet to my PC, which is running Ubuntu 14.04lts. The connection is fine for browsing, however whenever I stream video or audio it stops after about five minutes and is stuck buffering. The router is in the same room, and if connected with the Ethernet cable streaming is not a problem. Do you have any advice?
