We're waiting to see it that's the case for us, too. For about 5 years we had broadband connection that would vanish with the appearance of crackly telephone signals whenever it rained heavily, snow melted, or heavy fog lay on the land and water got in the lines. So basically any time between October and April we could never guarantee being able to access the internet at all. Then of course you have the 3 days post-wetness where you get sub-dialup speed internet until the dynamic exchange realises the line works again.
Every time we reported it as a fault, initially BT would say that as we pay them to use the line for telephony, they aren't obliged to fix problems that knock out broadband. When we got Orange to send someone out eventually, the BT Openreach engineer said he found a fault outside, managed to switch three or four neighbours' telephone lines at the pole by reconnecting wires wrong, and when he got back to his workplace he reported it was a fault with our home equipment and charged us money which took a few months fighting for BT to admit they should never have charged us.
Eventually, both Orange and BT said that they were not contractually obliged to fix the problem because Orange aren't responsible for physical faults with the line and BT aren't responsible for our broadband connection quality. However, both said that if we consolidated our services with either of them, then the one we picked would fix the problem for us. So we consolidated telephone and broadband.
With Plusnet.
We took the opportunity to upgrade to the recently connected fibreoptic broadband, and since then we've not had issues. We're hoping it's because the fault lies in the copper between the box and the exchange (which we now bypass) and not because it's been too dry to get bad.
However if it does get bad again, BT Openreach won't have a leg to stand on. It's their fibreoptic modem we have to use now, and it's all their property from the modem all the way down to the exchange. If it can't sync, it's *definitely* their equipment at fault.
