It's fine if you are in the same room as the WiFi router or source?
Given how neighbors can put in some 802.11n router and not set it to be neighbor friendly (sorry but I'll let you research that issue) you are left with using the laptop in that room or installing more hardware.
The best solution I use is a powerline bridge and a second router configured as a WAP. The high price on that is just under 200 bucks. But it does solve it.
I can't find much about the settings so try the router/thing defaults and then a simple ALPHAnumeric SSID (do not hide it) and then move to WPA2 AES personal security and see what happens.
If the router has an auto select for the channel, use that.
