So I've always been troubled by crappy WLAN's in my hotel rooms and everywhere else I go. I always seem to end up with maximal signal quality around 35, and it seems like most my devices need 40 to function properly. Not any more.
Using the following stuff, I seem to get decent access all the way down to network signal strengths in the 20's; I have yet to determine the exact lower bound. But certainly throughput increases with better quality.
I configure the dlink router to function as a repeater, which means I can sign on to the hotel network from my iPhone/laptop as if it were the normal network. The only difference being that it works ;)
You can basically use any wireless access point that supports repeaters and just buy the external antennas. I seem to be getting more punch towards the hotel AP by using the directional antenna vs the unidirectional one. So I point the directional antenna at the hallway and use the big unidirectional antenna to provide access within the hotel room.
Please note that komplett.no
are quite expensive wrt the directional antenna, I bought mine for about 2/3 the price elsewhere. As can be seen from the picture, the unidirectional antenna is quite large ;)http://www.komplett.no/k/ki.aspx?sku=623085http://www.komplett.no/k/ki.aspx?sku=357863http://www.komplett.no/k/ki.aspx?sku=578308
