I've been having some issues with my broadband ADSL connection which has been persisting for some time. I've tried almost everything I can think of, but I have no idea what is happening.
A year or so ago, I started to have a significant number of disconnections and a reduced ADSL speed (up to six disconnections a day and the speed below 1MBPS, compared to about 4MBPS at it's peak). The speed seemed to rise and fall persistently with no obvious cause. I contacted BT and they came out and changed the telephone box, claiming it was faulty. They also tested my microfilter and found it was defective and I produced another which they claimed was fine. After this, the internet connection speeds and connectivity were vastly improved.
About three or four weeks later, I started to experience the same disconnections and speed drops which progressively became worse. I changed just about everything I could think of, but nothing was working. I then noticed that when I changed the microfilter, the problems seemed to clear up temporarily and then resume their previous pattern. After some tests, I've discovered that the microfilters seem to fail consistently after a few weeks.
I'm at a bit of a loss as to why this is happening, so I wondered if anybody here might have any ideas as to what is going on? I've replaced about six or seven of them now of all different brands and configurations and nothing seems to help. At this stage, I just want the connection to work properly as designed
If anybody could help me, I'd appreciate it
