Im sticking to wireless USB adapter w/ antenna so I can extend the range and choosing USB over PCI WLAN cards so I could place them on the spot where the signal is strong.
Anyways - I'm currently having trouble with my USB WLAN adapter that I bought..
Please suggest some Wireless USB adapter w/antenna(preferring-double antenna) that you have used and is excellent at performance..
currently I'm watching over this http://www.encore-usa.com/us/product/ENUWI-2XN45
Please suggest thanks )
by the way I currently own this Wireless USB adapter and not really happy w/ it's performance in terms of speed event though the signal is fair at 3/5.
