I am using wireless connection on broadband and have just bought a new telephone. The reception is really bad and can't use internet when phone is plugged in. ON checking phone instructions it seems that I need to buy a microfilter to help with the reception problem. My problem is that when I asked in a store about microfilter it seems that I have to plug the pc and telephoen into the filter but I have a wireless connection - I switch on the pc at top of house and phone at bottom. So if I buy a microfilter can I just plug the telephone into it and will it make a difference to the reception.

You need one on the plug point the router (broadband box) is plugged into - and probably on others as well. Did your router not come with any - most of them do?

So I need one on the broadband box and the phone line - So I need to buy two microfilters? Sorry I have not a clue. My old phone worked perfectly and can't understand why the new one is so rubbish

Yes one for the broadband box and one for each phone. Not for the PC if the PC connects wirelessly to the broadband box.

probably, yes - but check the broadbad box first as it may already have one on.

Have you added an extra phone, or replaced one? If you have added a more complicated one (IYSWIM) it could explain it - try unplugging all other 'phones and see if that makes any difference.

You need a micro filter plugged into any phone point which is in use - router, main phone, extensions etc.

You only need a filter on devices which use the regular phone service ie telephones, fax machines, answering machines etc. You don't need a filter on your router.

In your case, you need to buy one filter for your new phone.

OK thanks for all your great help. I went into Commet and explained to them what I needed and they did not know what A MICRO FILTER WAS. Does anyone know where I buy them and how much I'm likely to pay.

Our router is plugged into the microfilter (it has 2 sockets so you can plug the ohone line in too)

flowertop, online might be easiest - google microfilters - or try eg PC World if you need one right now smile

You can get them off ebay - I just took a quick look and you can get them for about £2 each. Just look for an ADSL microfilter and loads will come up. I think the BT website also has them if you'd feel happier there, but no doubt more expensive...

You do need a filter on your modem aswell. The whole point in the filter is that it filters things out which will interfere with your service - prevents high frequency noise interfering with your telephone and prevents the telephone equipment from interfering with the modem.

Hence you need one plugged into any telephone point which is in use.

Ebay is probably the cheapest place to get them from!

Sorry, that should have said you do need a filter on your router aswell

You do not need a filter on your router/modem. grin

TequilaMockinBird - the microfilter is a low-pass filter which stops the dsl signal passing through to the phone (making a noise) and ensures that the phone presents a high impedance load to the line. On those two-way filters, the output for the router is just a convenience feature as most people will want to plug a phone and a router into the same wall socket. There is no filtering between the wall-socket and the dsl output of the microfilter.

Larger supermarkets often have them. I've seen them in Tesco and Asda.
