Rather than spend all that money on the Billion 7800N router, you should have bought the very reasonably priced BT Business Hub 2Wire 2700HGV router, renowned for hanging onto long lines.

The Billion will be useful when you get FTTH (Fibre To The Home).

Might be worth trying to connect a corded phone into the master socket or better still the TEST socket within the master socket if it's that type, see this link.

Once connected dial 17070 and take option 2 for the quiet line test, listen and if you here any noise you should report it to your phone/calls provider as a "noise" fault ....... do not mention Broadband or your problems with Bb as that will just confuse the issue.

Well, thought I'd give a little update...

There is only one socket in the house, the master socket (brand new), one router, one cordless phone and one corded phone all plugged in there (properly filtered of course).

So I did try this morning to get them to test the line, they said I had to phone back from my mobile since I was calling from the landline, which I did. I was then told that it tested perfectly fine and then he started going on about master sockets, test sockets, filters etc...

Then this afternoon I got fed up and phoned them again, and this time purely by chance I heard the sound of someone elses ringing (again!). Sooo, I told the next guy this, and he said he would test the line, which he then did, with me on hold on the landline he was supposedly testing (???). He comes back and tells me right enough theres a fault on the line, and he is "escalating" this issue to... whoever is next up the ladder.

Also I've had an idea re the electric fence, as there is one where the cable switches from underground to overhead at the bottom of our road. (I think its roughly Exchange - 5.5km underground - 2km overhead - house).

So I've kinda forgiven the Billion for being so useless, but its still going back. Instead I'm going to hunt for a reasonably priced router with an Infinion chipset (seeing as the DM111P V2 is Infineon and managed to sync at almost twice the speed of the Billion under identical circumstances). D Link is back on, syncing similar to the Billion.

At least I'm hoping a partially crossed line would affect the broadband... but it is pretty disapointing that I have this problem less than a week since the BT engineer supposedly sorted it!

Thanks, JF.

Interested to know if you ever got all this sorted out ?

I have a long saga ongoing and you are more than welcome to check the TalkTalk members forum under my user name for background.

Hi similar to our problem on a long line with BT. Router rebooting and the BT IP profiling system forever dropping our speed to 133kbps..

After going on 15 engineer visits I pulled the plug and moved on to BE. Instant improvement of 3 mbps.

Probably going to have problems again with the impending Sky takeover and a decision of to whom my business should go to as I understand Sky have IP profiling like BT!

Sky LLU does not have IP Profiling of the BT kind, only Sky Connect does.
