A looooog time ago I used to come to this forum all the time but since having cable I only read the news headlines.
I know there are some very technically cleaver people here so would be grateful of some help. I am trying to help a friend who is complaining of low speeds. They had their modem connected in a converted loft which I moved down to the master socket and installed an i-plate. With my limited DSL knowledge I confidently said “You should see at least some small increase in speed over the next two weeks” - Well, I was wrong
Looking at the modem they are getting the following values:
Values displayed as down / up
Data rate(Kbps): 1152Kb / 288Kb
Noise Margin: 9 / 19
Output power(dBm): 123 / 182
Attenuation(dB): 54 / 31
When I enter those values in various online calculators I see suggested speeds of up to 4 Mbps. Now I can guess not every line would get the suggested speeds but 1152k is way out.
The really frustrating thing is they are connected to the Sevington exchange near Ashford, Kent that has no current plans for fibre. 300 meters down the road is a fibre cabinet coming from the Ashford exchange so houses around are getting fibre but they can't because they are connected to a different exchange.
Even if they could get an extra megabyte it would make a difference to them and I thought the i-plate might help with that. I am probably missing something obvious here or perhaps the levels are so bad they are lucky to get 1152k. Any suggestions or advice would be gratefully received.
