May be the building site has installed WIFI with strong signals, can you t ...
Thanks.
Yes, Changed all channels, and failed, sometimes success, but another day will fail.
I've installed Analyzers in PC to see the changes in different view, ALL signal near my home (other home routers) will be up and down and disappear when the site operate, all of them will normal again after 5:30pm (the site close)
I cannot locate the site signal it may not be wifi but their channel interfere with all wifi
I've complained to Wifi but they decided not to open the file after discussed as Wifi is public not under controlled.
May be the building site has installed WIFI with strong signals, can you try to change channel? Actually if you have Android phone, you can install an app called WIFI analyzer (free) to look for channel distribution and try walk back and fro to locate the signal source.
If you can confirm the signal is from the building site, you can complain to OFCA about their signal too strong.
