I can access university WiFi from my dorm but its only 2 bars and keep dropping like every 30minutes and I have to reconnect. If I buy a USB antenna that I saw online will that improve the stability of the network or I will only get a speed boost with the WiFi still tripping? I bought a Tenda range extender but somehow it just cant play nice with the proxy settings (leaving me with a strong signal but no internet access) so I am beginning to think maybe a USB antenna might help.
