Connection Droped Considerably

[gafferz]

When i first joined o2 i was told that i could get around 7meg (i didnt think that that was possible) and when i first connected i got around 3.5meg which i was happy with but resently the connection speed has dropped below 0.5meg! and i was wondering why this has happened

Line stats from the router plugged into test socket

Thanks for any advice

You have severe line noise - if that's in your test socket and you've tried different filters (they can fail) then the problem is probably in your BT line. The reason I mention filters is that your upstream attenuation is way too high compared to your downstream and this can indicate a filtering problem. Your noise margin is a little high but that could just be the router/exchange equipment struggling to make a connection.

Call Sky and ask them to investigate. They'll call out a BT engineer if they agree that a line fault looks likely.

BTW, your attenuation will only support ~3meg though it could be the line fault (if there is one) has increased the attenuation a few db.

thanks for the advice im going to ring o2 and see if they'll send a engineer out to sort out my line

. . . . . . once you've double checked your filters?

[gafferz]

checked the filters and no change in connection

if a bt engineer is called to my home would i have to pay a call out charge

Just checking - is that noise margin and the sync speed staying the same?

Only if the problem turns out to be in your home wiring - but if those results are from your test socket (the one hidden inside your master socket) with nothing else plugged in that pretty much points to the BT line being the problem. However, if your sync stayed the same but the noise margin went up significantly then that would indicate something local.

checked and no variation from test socket to filtered so rang up o2 and they put me on a 24 hour test will post what they say when i get a phone call back from them

p.s thanks saturday for the advice

[gafferz]

o2 are checking all their equipment before they ring bt so i have a new router arraving on friday and they will be more tests through the weekend and then if no change they are going to contact bt and get them to come and have a look at the phone line

That makes sense - a faulty router is definitely a possibility though not the most likely from the symptoms you describe.

stats have increased even tho i have not changed the router

new stats
