I have a spare adsl modem for testing purposes when asked to check out problems for people. I noticed a severe drop in my broadband speed from the normal around 7MB to 1.5MB. On investigation I found that I had left my spare modem plugged into the phone line in my workroom. This was not connected to the power and I would have thought it would have had no effect on my phone line. With it unplugged I was back up to my normal speed. There is still a lot to learn even with my age and years of experience. I have had a pc at home since 1975 and still get caught out now and again. Have a good Bank Holiday all.
anything plugged in and not on a filter will cause problems.
We've all do something simular, I had booting problems messed for hours and finally decide I need to do a repair install from CD. Opened the drive to insert XP CD to find a blank CD in there, this was the cause of booting problem, booted OK with no blank in the drive.
Yep, tried that, no difference so must be old copper wires from there to exchange or a problem along the way at one of junctions. Things do wear out, will await BTOutreach checking of line. At least I now know it's not my internal wiring etc.
