Every time someone phones me or someone in my household phones out my internet connection drops and takes what seems like an eternity to reconnect.  I am on the flood plan and use a Linksys Wireless G ADSL modem.

Please can someone tell me if this should be happening because I don't think it should.  And if it's not right how can I go about fixing the problem?  It's driving me insane!

I am new to all this broadband stuff so any advice is appreciated!

Thanks

Has your line been split (either because you have an alarm or you have more than 4 telephone sockets) or have your put filters on all the phones in your home?

I don't have an alarm and I only have 2 telephone sockets.  I have a handheld phone which connects to one of the sockets in the kitchen area and I run the modem from the other socket via a longish wire in the living room area.  My understanding of filters is that I shouldn't need one if I run my phone and modem from seperate sockets.  Correct me if I'm wrong.  Any help is appreciated!  Thanks.

Not necessarily.  If your line has been split, there would be two sockets right next to each other, normally labelled as well.

Put a filter on the handheld phone in the kitchen and see if that fixes your disconnection issues.

Unless you have a master filter/splitter installed *every* device in the house plugged into a phoneline such as an alarm, sky tv, phone, fax or medical alarm requires an ADSL filter to be used. You do not need one of these for the modem.

One of these for the phone will more than likely fix your issue.

As I have stated in the other thread you have running, you must place a filter on every POTS (Plain Old Telephone) device, connected to your line. To clarify, a filter is required to be connected between each POTS device and the line to stop those devices from effectively shorting out the ADSL signal (especially when ringing and being taken off hook) and causeing your DSL connection to drop out. Further to that without the filter those POTS devices by also effect the maximum rate that your ADSL service may achieve (always for the worse). Your ADSL modem connects directly to your line and not via a fitler.

Cliff notes:  Put a ADSL line filter on the socket in your kitchen socket before the handheld phone.

There should be one in the box that came with your ADSL modem or you can get one from a local computer store or Dick Smith for <$20.

Yes you are right....according to the package contents on the modem box it says 'microfilter (UK SKU only)' which I am assuming to mean that there should have been some kind of filter in the box.  But there wasn't any in my box!  I keep everything and all that is in the box now is the receipt.  Pity I bought it in June 08 and I'm only discovering that there is no filter in there now!

Oh well....I'm off out tomorrow to buy one....wish me luck!

Not quite sure what you mean by this. An ADSL filter *is* required and the OP doesn't have one. If you have a phone plugged in without a filter (and don't have a master splitter installed) you will cause issues due to the frequency clash.

Yes and no... I have come across cases where no filters are in place and everythings running fine. Its a rare occurance though.

Yes, very rare.

The days of DIY installs are fairly numbered anyway. The reality is plug in filters don't really meet the ADSL2+ requirements and are unusable for VDSL2+. For regular ADSL isn't not an issue for for good ADSL2+ speeds is not recommended.

The only way to guarantee good ADSL2+ speeds and certainly the only way to ever get VDSL2+ is to install a central master splitter.

A friend of mine had the same problem and after trying a new modem and filters on all phone jacks it turned out to be a broken wire on their line just outside their gate

It can work fine without a filter if the phone is a good quality design (not brand, but design) which has a filter already built in.  This might have been for EMC issues though, to prevent radiated noise, but depending on how it is done can also act as an ADSL filter (which is just a low pass filter, nothing fancy at all).

One issue with plug-in filters is that they are cheaply manufactured and thus fail often, or can be at the wrong frequency and degrading your performance.  It might happen sudden or it might happen over time, so you do not necessarily notice it.

A central splitter (which is also just a filter) is of higher quality using larger components that do not saturate as easily and are manufactured to last longer (being permanently installed).

But if you go with Fusion, then there are no filters at all to worry about ;-).

Thanks to everyone who helped me and posted info on the issue I had with my internet connection dropping when my house phone was used.  It is now a thing of the past since I purchased and installed the filter today.  Problem fixed.  Thanks again!
