Broadband/router comms query

Heedtheadvice

Been having problems with connection. BB keeps on dropping out/losing sync. BT ISP with home hub 3.

Would someone with appropriate comms knowledge please have a look at the following to see if there is concrete evidence to get the router replaced or if there is a possibility that something else is coming into play! It seems like something is causing the line to disconnect from the router.

Openreach have tested the phone line (voice) from Master socket (router plugged in there) and all tests show good connection, no dropouts and good low noise connection. Openreach BB test equipment connects fine.

BT home hub router drops connection frequently and is often not connected for long periods. ( This happened just before and just after Openreach tests this afternoon) Suspicion is a duff router. Note Filter is built into a relatively new master socket. Engineer was only tasked with testing phone line !!!!

Event log around the time of a disconnection under fault conditions is as follows (newest events first):

13:59:45, 31 Oct. ( 20.270000) Booting firmware 4.7.5.1.83.8.94.1.52 (Type A)

13:52:05, 31 Oct. (33239.030000) Admin login successful by 192.168.1.98 on HTTP

Not sure if this is relevant but there are a lot of 'BLOCK [15]' by Default Policy and others both 'IN' and 'OUT'

Help much appreciated....

The "Block 15" things sound like it's just the router stopping incoming connections, which is completely normal if the router isn't expecting them, people/bots scan for vulnerable ports on connected equipment, routers stop those attempts).

It used reckoned that a new Windows 95 install could be compromised within about 15 minutes of being connected directly to the internet, back before the default Windows firewall setting was "on" and most people connected directly via a modem of some kind rather than modem with router.

"in" and "out" are normal as well, that's network traffic.

Given it's "aiting for underlying connection", I'd guess the issue is with the DSL connection, most likely line noise/signal but I'm no DSL expert (never used it), I think you need to find the line stats from the router, namely the Signal to Noise Ratio (SNR) and I think strength.

I would factory reset your router .
That fails then use your BT members page help / community forum . This can give you a better response from CS.

Thanks both. S/n ratio is fine as is signal level plus other equipment (openreach test unit) uses line fine.

Good suggestion, will contact forum.

Do you have any phone extension sockets?

You can buy the genuine BT master sockets from loads of places and changing the front plate is two screws and pull - anyone including yourself can do it. If you don't have any phone extensions then I'd just bite the bullet and swap out the faceplate at my own cost.

Thanks for your response Tarambor.
However I do not follow your logic and the new Master socket is new so nothing ought to be gained from changing it again?

I assume you're pestering BT. When I had a similar problem they sent me a new later model router & reduced my monthly payments.
