Hi guys, I have windows 8 pro version 64 bit in my Dell, Inspiron N4050 model.. and I never needed any driver to install before... for some time, my laptop r windows is showng strange behaviour... it didnt pick wifi signals from the next room and it does some time pick weak signal from 2, 3 rooms away (weak signal of other wifi) while strong signals of nearer wifi didnt show up.. and I keep my laptop running for 2, 3 hours and then my laptop pics wifi signals from the next room... can any one care ro explain y such odd behaviour??
