hi i joined o2 about 3 months ago since day 1 my connection keeps dropping 6-20 times a day, i must have phoned o2 20 times, i have had 3 new wireless boxes tried using a netgear DG834G router and it still disconnects I have had 5 openreach engineers at my home they have run all possible tests they say my line is fine
my router stats are
Current Training Status : Showtime Current trained adsl mode : G.Dmt Current trained adsl path : Interleaved Downstream Bit Rate : 6784000 bps Downstream Noise Margin : 11.0 dB Downstream Attenuation : 20.0 dB Upstream Bit Rate : 448000 bps Upstream Noise Margin : 16 dB Upstream Attenuation : 39.0 dB
Openreach said they checked everything at the exchange and everything was fine, i have tried monitoring my router with router stats just before my connection drops my RX noise jumps from a steady 8 -11 db to 40+ db then i loose my connection and sync, after a few secs i get my connection back. Openreach fitted a special noise filter before my main BT box it made no difference I have my router plugged in my test socket, tried fitting new adsl filter, tried using different cables openreach think my line is picking up interference from somewhere O2 say there is nothing more they can do if i want another engineer i will have to pay £100+ so Im stuck with this
Sadly, not uncommon, I think you need to look outside of the phone line and the router. For example, I've heard things like microwave ovens, lights, TV/DVD/HiFi all chucking out enough RF to upset this delicate technology, let alone the mobile phones sailing in or past your house. Could even be the neighbours petrol lawnmower.
In the short term, I suspect the only fix is to change your technology - which is probably not what you want to hear. For a test, try grabbing a different router off eBay for 50p and see if that suffers from teh same fate - at least you'll know!
