I live in a huge apartment building and have a dlink 2.4 ghz wireless N router. I have a 20/2 connection that is right on the mark at 20/2 when I'm wired to the router. When I'm sitting in the same room as the router but using wifi I've got a 15/2 connection. 20 feet away at the desktop PC in my room I've got a 3/2 connection that drops out ALL THE TIME. I'm assuming it will only get worse as the building next door gets 4G antennas on it. There are nearly 15 wifi networks in range. I downloaded an app to see which wifi channels were being broadcast on, and changed mine to several different channels in an attempt to increase the connection strength to no avail. The best I could get was 5/2 and intermittent cut-outs in wifi. Wiring the network is not possible since the Landlord will now allow this. What is the best bet that I have? Should I try and set up a wireless repeater or a wireless access point somewhere? Would a 5GHZ router solve my issues? Any advice? I don't know a whole lot about networking. Thanks.
