My ADSL2 line has now been reliable for about a year. Over the last few days, when the connection has dropped, I checked the S/N ratio using Routerstats Lite and can see that the S/N ratio drops from 3db to 0db for a few seconds every 4 minutes. Looking at the graph the period between the drops is very repeatable. After about 30 seconds, the modem recovers and broadband works for the next 3 1/2 minutes. Swapping out the Netgear DG834V4 for a DG834PN makes no difference to the result. The question is:- can anyone think what could cause a spike of interference every 4 or so minutes in a regular pattern? I have seen noisy lines + fluctuating S/N ratios in the past, but never a regular and repeatable sequence of signal drops.
Hi there, I can see that you've basically not been able to use the internet over the past couple of days; <img src="http://community.plus.net/visualradius/generated/image13789150771091.png"/> Are you connected to your test socket and tired an alternative micro-filter?
