Here in SW Wales we have had to live with being in a slow spot area; however, it seems that it's not just the relative infrastructure weakness that is at fault.
I have been trying to get my ISP to properly address what appears to be a central problem in our area. Since the start of this year our broadband speed has been very poor (0.1-0.3M) with occasional periods of excellence (once I even recorded 2M for a 24-hour period). I've now given up contacting the phone helpline and now email in 'complaints'. I've had two engineers visit the house to test the line, etc. and can find no fault at this end - their line tests indicated that the line should support 2.5M (in one case) and 3.5M (in the second). The third engineer contacted me from the local exchange to inform me that a problem existed at the exchange and that there had been over 800 complaints registered about it. In each case a phone call from BT assured me that action was underway to correct the fault. Each time the connection to the server would be re-started with an initial substantial improvement in bandwidth (usually around 1.5M) but within a week it returns to the usual trickle. Needless to say each one of these 'remedies' takes a couple of weeks.
I've run the BT diagnostic regularly which shows that the IP profile starts at a good level but drops with the bandwidth speed. One of the engineers did mention that the 'noise' level on my line does not follow the normal pattern, but could not suggest a reason.
I'm unsure whether it is a coincidence but most times the start of the reduction in bandwidth seems to be after a weekend.
I've now received a call from BT Vision offering terms for a contract. The rep expressed disbelief that I couldn't get 2M as his records indicated that 2M should be the minimum I get. Checking the thinkbroadband 'map' there are a lot of tests below 0.5M although a number above 3M.
I'd appreciate any advice on the likely cause of this behaviour in my connection, but what I'd really like is advice as to how I proceed now to submit a complaint to Ofcom about BT's apparent reluctance to conduct a proper investigation leading to a permanent solution.
In addition, am I right in thinking that there's no point in trying a different ISP if the root of the problem does lie in the exchange?
I'd appreciate any advice
