Broadband disconnect with rain
Unlikely as it sounds, I have a persistent disconnection every 2 minutes when there is heavy rain with about 10-15 miles of here. 'Give me sunshine' - and I have a solid connection. Storm clouds gather, off it goes. WIFI or wired. My ISP has been good so far in chasing this but I seek some ideas.
Today BT came out to check. Day - sunny. Line PERFECT. Checked in the house and at the exchange. I assume there is an underground cable somewhere that gets wet - but how do I progress this?
