globalti a few things to check..
Try all this at the NTE test socket first.
1. using a WIRED phone, listen for noise, crackling or a buzz?
2. any problems with overhearing other people?
3. When people call in, do you have any ‘ring tripping’? (rings once or twice then stops but when you pick up someone is there?)
4. Does the ADSL synch drop when the phone rings?
If you answer yes to any of these, you have a possible line fault – call your CP and get an engineer to check. remember to describe what you are experiencing to him/ her.
If all seems clear synch up your router at the NTE test socket.. get onto the admin page and write down what speed you are synched at, plus make a note of any erroring that might be occurring.
refresh (F5) that page a few times, if the errors are counting up at a vast rate, you may have a line problem that can’t be detected by ear.
If all seems OK there, now check you internal stuff..
Is the wiring in your house likely to be affected by damp? Cold walls, wires or sockets by windows etc.
For internal wiring..
Re-attach the NTE frontplate (i.e connect your extensions)
Leave the router unplugged for the time being.
1.Do the same checks as above from each of the sockets., is there any noise now that the internal wiring is connected back up on the NTE?
2. try and synch up your router, (with no other phones plugged in anywhere) do the same admin page checks as before.. any difference?
3. Try synching up with different filters, you have several right? Any difference?
Post here your results please.
ps. Flaperon, how do you describe an engineer please?
