hi, I am unable to connect to our home WIFI on either mine or my mothers desktop pc. when i open the WIFI settings on either desktop it shows up my neighbours networks but not ours. other devices connect via WIFI and work flawlessly. these desktops work fine when connect via lan cable. have bought and tested multiple different WIFI adapters with no luck. I'm quite handy when it comes to technology but this has me stumped. Cheers.
