I'm in Bangor, which is a city dominated by the local university. I'm very close to the exchange and have a pretty much perfect ADSL sync. Over Christmas and new year, I got 7.1Mbit/s download all day, every day - it was great!
However, the students returned at the weekend for this week's exams. I'm now getting around 600kbit/s during the day. After 2am or 3am it will gradually climb back up to 7.1Mbit/s which lasts until 8am.
This is not unique and is the same pattern that I've seen over the whole of the last year that I've lived here.
Plusnet show the BT exchange as oversubscribed:
When this goes green, speeds are okay for a few weeks before dropping back down towards 1-2Mbit/s followed swiftly by sub-1Mbit/s.
My question is whether this is Zen's fault or BTs? Is anyone else here living in Bangor and seeing the same speeds? With Zen, or all ADSL suppliers?
I don't want to leave Zen, having had perfect service from them on another line which I have at an address 60 miles away in Wrexham (which, incidentally, will download at 6.5Mbit/s day in, day out, at peak hours and in the middle of the night). I also don't want to switch and find myself in the same situation!
Could there be any other solution to help with this problem? I believe ADSLMax doesn't have any concept of the lower contention ratios that were available with the old fixed 2Mbit/s ADSL products. Money is not an object if the problem can be decisively fixed.
