Last night, in fact very early morning, about 30 minutes after I'd shut down my PC I noticed that my router's LED was flashing indicating it had disconnected and was reconnecting. I fell asleep before that happened. 🙂
All looked OK next time I checked, 9am but I received a 'silent' "No Number" telephone landline call at 11.20am. What I noticed immediately was that the line was very crackly. I've not had that sort of problem for a long time.
Booted up my PC and checked the BB speed and from my now usual 50+Mbs it was back down to poor pre-FTTC download speeds ie. below 2Mbs! My upload speed was also down in speed from a typical 17+Mbs to 14Mbs. That disparity between the download and upload speeds indicated it was most likely an external fault of some some sort.
Anyway I rechecked with two different speed testing sites and both confirmed the speed drops.
After running TT's diagnostic and line fault 'fixing' tool it, eventually, reported the fault had been repaired. So I tested the speed again and indeed it is back up to the lower end of the expected range 45Mbs/14Mbs. I guess in time once the line is 'stable' after whatever this problem was/is it will get back up to the previous 50+Mbs/17Mbs level.
However, when I checked my landline and I could still hear crackling on the line as though there was an open connection.
Needless to say I have not added too or changed any of my telephony or other connected devices for, literally, years so this concerns me. It is or must have been an external problem and why I am reporting this here now in case the problem isn't 100% fixed and reappears in the next 48hrs.
If there is no repeat of the problem I'll re-post to mark this issue as resolved. Fingers crossed because I really need to be able to use the internet without any problems tomorrow.
