I have 12 MBit DSL service at home. At some point it was changed to 14 MBit without my knowledge.
Then, two days ago my connection went completely down. The provider moved it to 12 MBit but I still couldn't get a connection. Today it was set to 7 MBit and I now have a connection, but I am trying to find out why it suddenly couldn't handle the capacity.
A technician tested my line at the demarcation point outside and said it could handle 14 MBit, and suggested it was the modem failing. Is this possible for a modem to slowly lose speed over time? Is there any way I can test it at home to confirm this?
I know the usual suggestion is to try it on a friend's line but this is not an option. I would love a sure-fire way of checking the modem to see if it is truly "dying" or it is something on the provider's end.
- It's a 4-5 year old Thomson Speedtouch 516 (ST516). This can handle adls2+ e.g. up to 15mbit. It was provided from my ISP and I confirmed with them it can handle these speeds (and again, it was for 5 months at 12mbit no problems)
- I've tried rebooting, resetting, connecting directly to computer, different jacks, etc
- nothing else on the phone lines in the house
- the stats below seem to have A LOT of errors e.g. FEC erros at 588 million. what does that mean??
