      Unhappy Connection keeps dropping out (sorry, another one!)

      Hello again!
      For the past week or so my speeds have been dipping to a couple of 100kbs from the normal 3-4mbs. The past 2 days its been dropping out completely every so often.
      I've tried rebooting which works for a while, i've checked all the wires, replaced the microfilters and even tried the master socket on my phoneline box. nothing seems to have worked.
      Oh and i'm connecting by Ethernet cable not wireless.

      These are my stats:

      the stats posted are for to short a time to get any real info, could you post back tomorrow.

      also above you said about the master socket, but if you have an NTE5 socket(with 2 screw on front) could you take the front off and try the test socket behind ( to help in ruling out your internal wiring)

      Yep no problem

      When i said master socket, i meant the test socket. (sorry i didnt make that clear)

      Re: Connection keeps dropping out (sorry, another one!)

      Well i seem to have fixed the constant drop outs (i unticked the UnPnP box in the router settings) but i still keep getting dips in speed. It was dropping to 100kbps then back up to 3Mbps within a few seconds. Its not so bad if i'm just surfing (just means pages load slower) but its long enough to log me out of MSN or Xfire or kick me out of a game like Warcraft.

      Its starting to baffle me lol!

      the CRC errors are whats causing the slow down, as you are in the test socket there is not alot more you can do (could try a quite line test on the phone to see if you can here any crackling/hissing, info somewhere on forum)
      but looks to me like noise spikes, see if speed is dropping at certain time of the day and see i this is the same time as things are turning on (central heating/microwave / lawnmower / street lights / alien landings )

      also if you use a dect phone, you could try moving this away

      there are a couple of programes that keep a log of the errors (one is mosseywells and one by James67, these may help in pin pointing the times)
