Main Telephone socket downstairs with Filter plugged in. Splitter attached to filter servicing phones in lounge and kitchen.
Phone extension to Bedroom with Filter attached. Router ONLY attached to Filter.Speed connecting to Internet a poor 3mbps download.
Moving Router downstairs and attaching to filter speed shoots up to 9mbs.
Obviously wish to retain faster speed but if poss would like to keep router in bedroom (away from the kids) without loss of speed. My supplier says there must be a problem with the extension upstairs but this is not the case as I have tried another extension with the same result. Any suggestions please
Many thanks

remove the ring wire from the face plate of the master socket.

you are not clear about the extension and how it is wired. is it wired in to the socket?

The general good advice is:
Avoid using telephone extension cables

A poor quality telephone extension cable can increase interference on your line which will affect your broadband speed.

If you can, you'll be much better off connecting wirelessly or if you have to use cables, get a longer Ethernet cable to bridge the gap between your router and computer.

If you have to use a telephone extension cable use a new, high quality cable and with the shortest possible length. Tangled and coiled cables can cause interference.(From Plusnet)

and



We always recommend that you connect your broadband router directly to your master socket, as the signal will be at its strongest there. Please use the cables supplied, and although you can use an extension lead, it should be avoided if at all possible as it may slow down your connection, or even stop it working altogether.(from TalkTalk)

Hi all
Thanks for the replies so far. Looking outside the house there is a junction box which I assume brings the comms in to my front room as the master socket is located directly behind. A second cable exits the junction box and this is tacked to the external brickwork and feeds into my bedroom upstairs where the second phone socket is.
FLAGPOLE - Not sure what you mean by " the ring wire from the face plate of the master socket"?

Thanks for all responses. Looks like best option is to leave router attached to main socket so will do that for now and try to keep hidden from kids. Might also look at telephone extender where signal goes across internal electric wiring system
