Hi
I'm sorry but please, why do you keep thinking it is noise causing issue
If I understand your posts correctly (apologies if I have not sorry), but you posted that your devices lose connection to your router (ergo also internet due to loss of Lan connection) on both wifi and hardwired
Noise would not do this
In terms of neighbouring wifi, there are laws for restricting wifi power output
I think but have not looked on mwstats, that all your router reboots have caused DLM to intervene so best advice is leave alone or DLM might take more drastic actions such as banding your line
You said you have ordered a new router, so wait and see how that performs first, but given you have had a DLM action, when your ready to install new router, power off old router and do not connect to broadband for at least 30 minutes on the new router
Many thanks
John
