I had my cable go down on Wednesday - it would stay up for half an hour after resetting the cable modem. So - a quick call to their tech support only to be told that it had to be my wireless router - hmm, I began to wish I hadn't blogged that Dilbert cartoon on 12th May! So - I tried another routers and even hooked the ethernet out of the router directly to a couple of computers. Of course when I called back the guy was on his break and I had to start the whole procedure with another person. Anyhow - today I had the tech support visit and the engineer showed me how bad the feed from the cabinet in the street was; -27dBuV - he said he'd normally expect to see -6dBuV! So - at the box end he discovered the port feeding my house was faulty and replaced it - nice signal level at the house. But, when he drove off the ping I was running fell over and the link was down again. I got straight back on the 'phone and this time got a representative who actually knew what he was talking about. When I told him the story and the half hour business he knew exactly what the problem was. A couple of days ago Virgin pushed out a firmware upgrade to the Scientific Atlanta cable modems and it corrupted the data rate sync settings so the buffer in the modem would over-run after n-minutes of use. See these screenshots if you're similarly troubled!

Just think ... if the first person you spoke to had known the real cause of the problem you never would have got that dodgy signal fixed!
