Title: ADSL FILTERS
Post by The_Trician on Jan 7^th, 2011, 6:29pm

ADSL Filters - are they all pretty much the same in terms of quality etc?

My local TV shop has them at £10 each, which I thought was a bit too expensive when I've seen them available online for £0.64 each.

For the last 7 weeks or so I have been getting intermittent internet connection and the router keeps on dropping the connection (SOLOWISE SR-130)

I have remade off the phone socket connections but this has made no difference.

I have to pick up the telephone handset, dial a digit and then put it down, then reset the router and it will work for 5 minutes or so before dropping the connection again.

I have tried to do the BT line test on their website but it won't work for me.
I'm loathe to call the bastards out because of a potential £100 call-out fee which is charged if the fault is not on their side of the line.

Filters do fail, even the expensive ones. Worth trying a swap.

However, have you tried the router directly to the master socker with all the extension wiring disconnected?

No I haven't tried that - Do you mean just plug the router directly in, with no connection to the filter or pc and see if it synch's with the line?

Or do you mean just omit the filter?
I can't do this because the router cable has a non-UK type plug with is incompatible with the BT skt.

I've tried using it with all the telephones unplugged but this made no difference.

You should try it direct to line. No extension wiring connected.

You can connect the router via a filter, but try a couple.

A router does not need a filter, it is the phones that do. A router will work without, but using a filter will make it easier to connect.

Do you have a modern NTE5a master socked where you remove the lower half to isolate the customer wiring?

What he said - try router in master socket.

If that works best layout is to plug one ADSL filter into the master socket. Plug the router into the network port on the filter. Plug any phone extension (s) into phone socket on the filter.

I don't know the Solwise but google says the line status page is accessed as follows..

There is a page within the router GUI that displays the line stats. Click the link below.
http://192.168.7.1
Click on WAN, then choose DSL and finally DSL Param

Should give you info on the line quality (S/N ratio, Attenuation etc.) Explanation of what the numbers all mean here..

Also forum here might help..

Could be faulty router. I think that model is quite old? Was your adsl speed increased 7 weeks ago? What might have changed in the house 7 weeks ago? New washing machine? Sky box? Heating on?

Well,
After much faffing about with cabling, swapping microfilters/phones etc, I finally called BT out and they found the fault 33 metres away from the house on a pole which had become overgrown with trees. Squirrels had had a good munching session at the line where it entered the box on the pole.
New line run this morning and all is now ok!

You do actually need to be wary of not using filters. The BT servers do a quality check on the data being sent to your router and if they are getting a lot of errors then the server will automatically reduce your line speed to try and compensate and gain a more stable connection. If you have something like a sky box connected to your phone line these can cause these types of errors that will reduce your line speed (happened to me).

Probably best just to slap a load of filters on there, saves loads of hassle.

I reckon it's best to simplify the layout so only one filter is needed and that's either plugged into in the master socket or built into it. That way you avoid running the high frequency ADSL signals all around the house.

The following will work but I reckon it's a mistake to do this in a house.. as you rarely have a nice neat line of extension sockets as shown!

Completely agree, one filter, one ADSL position.
