Virgin ADSL (LLU). Netgear DGN2200. Wired connection. History of a poor noise margin on this line.
My line has long-standing intermittent issues with briefly (<1min) losing its DSL connection which I had been wondering might be to do with line noise as I have intermittently heard this on the line too. I also often get a dropped connection when the phone is answered despite both phones having new microfilters. I was going to get BT to sort the line noise and hope it fixed the rest but it's so intermittent I cancelled as I didn't want a £100 charge from them for a call-out if all was well at the time.
Last night whilst running RouterStatsLite I noticed my connection drop at 10 to the hour and 20 past the hour like clockwork. I had earlier in the day downloaded >1.5GB from MSDN.
Today my connection started off OK and I set the PC downloading perhaps 1GB from Microsoft again (I get about 300KB/s). When I got back I saw that after a few hours it had started doing the connection dropping at 10 to and 20 past again! Noise margin has been between 8 and 10 all day.
I can't think of anything in the house that would run like clockwork like this!! I am half wondering whether Virgin are throttling me in some way for downloading a gig or two in the day and the manner of the throttling is in some way to blame.
I'm only here a couple of days a week so it makes doing anything other than brief troubleshooting difficult - esp since not all the PCs in the house could use wireless if I move the router to the test socket and disconnect the phone.
Does anyone have any suggestions as to what may be going on and how you'd proceed? Especially regarding the regularity of connection loss and disconnect on phone use despite new filters.
