Suggest that you get a laptop that has a Wi-Fi card in it that supports 802.11a; run something like inssider from metageek and look to see what channels are in use and what channels are free or little used.
Metageek also sell USB spectrum analysers that use an SMA connector so that you can connect to your external antenna and sniff to see what other signals are present. These are very cheap and useful for troubleshooting Wi-Fi spectrum issues with non Wi-Fi signal sources.
