There are several wifi sniffer tools that can run on a windows laptop, I have Acrylic Wi-Fi Free installed on this system and it lets me see how many access points are using each channel. There are several other similar programs. I often see 20+ 2.4 GHz wifi networks in my area, most are weak signals, but my router on Channel-11 is sharing bandwidth with a few neighbors and MePo over wifi does not work very well at my location. I tried a TP-Link power line Ethernet, it works better than wifi but I ended up running a Cat5 ethernet cable. A real wire works much better for me.
