I am getting very bad interference on all (4) of out digital telephones when my router is connected to Power.I have tried an old analogue at the first entry but it is the same. If I use the direct BT line it is OK (Take the front off and plug in to the direct line) If I unplug my router from the power the phones are OK. I have Reset the router. changed filters,and even replaced the extension cable to my computer. I had the same problem about 9 months ago, and after trying everything I could think of called in BT. It cost £230 for them to tell me it was not their problem, but about 2 weeks later everything went OK. I am not crying the poor tale but £230 is around half my state pension. Any advice please. Can this be atmospherics? We have very cold frosty/foggy weather at the moment.
I will look at that again in the morning, unfortunately I don't have the correct tool for connecting it, and I am a bit wary of reseating the connection.We are going out this evening so I will look again in the morning, thank you for you imput.
I have no idea why, but suddenly the problem has disappeared. Today is the first day that we haven't had freezing conditions combined with fog. It is below zero at the moment, but clear. I have changed nothing electrical, nor any settings. The only difference I can discern is Fog. Whether this can account for the problem I have no idea.
