I've had dozens of engineers out but they never really do much apart from say 'it's working now' or 'your power levels are all wrong'.
I've been using Ping Plotter to record the speed of pinging www.ntlworld.com I rarely get better than 10%-20% packet loss on sunny days, often much worse. 
Service tends to be fine at night but intermittent during the day. I would move to BT but I have two phone lines, one of which I use to work from home. BT can't guarantee a continous service with me retaining both numbers.
Any suggestions? |
Both Coax and Fibre are affected by temperature and if signal levels are marginal can cause problems with modem having to resync, typically 1 second pauses in my experience. New modems should be better - do you still have a 5 year old Terayon as I do?
Packet loss is somewhat different - in my experience this is observed when network components are over-loaded, the intelligent routers give more priority to real traffic and drop ping requests.
If is real packet loss there is a big problem somewhere - I suggest you PM a mod on this board to see if you can get someone above telephone support to investigate.
