TP Archer VR900 broadband temporary dropout

I have an Archer VR900 router which works very well. However I do have one annoying problem.
When making or receiving a landline telephone call the broadband connection temporarily drops out for about up to one minute. It resumes as normal until the call ends when it drops out again for the same amount of time. The original router supplied when I changed suppliers, to SSE/Daisy, worked absolutely fine. I only changed routers as the wireless range on the supplied router was not very good.
I have tried changing filters, checked for software updates, restarted it several times but there is no improvement. While it is not to big a problem it is an issue if any one is on the internet.
I just wondered if anyone has any suggestions.
Thanks in advance.

What you describe is usually the result of incorrect filter set up, or of a minor HR fault on the line. Is there any noise apparent on the line ?

Our main BT Openreach box has separate sockets, one for the router and one for the landline and is only 6 years old in a new build house. I have only fitted a filter to the telephone line.

6 years old is long enough that components might be out of specification, so best to test if this may be the case by removing the interstitial plate and testing the phone/broadband using a microfilter connected into the test socket.

http://www.coolwebhome.co.uk/faceplate/ shows how things should come apart, but be careful as their may be wiring attached to the smaller faceplate.

I have tested as suggested and also connected with a filter through the telephone socket, but still the same issue. My broadband speed remains the same (65+ down / 18 up) whichever connection method I use. Just seems a strange coincidence that this only arose with the change of router. TP no use.

Hi I came across this as I was searching for Daisy!

From your description, it sounds as though yr BT NTE5 master socket has the filter built in, so no additional filter should be used for the low frequency voice socket. You are effectively filtering twice. You can undo the face screws in the BT master socket and remove the incorporated filter, which I believe is just a separate add-on. Then you can try putting a standard filter in and see what happens. 1. removing the additional filter may resolve the problem, and 2, trying a standard filter in the master socket may eliminate an issue with the filter add on box.. Good luck

I have tried the various alternatives as suggested and unfortunately the issue has still not been resolved ;-((.
I don't no where to go now, so will try the original wireless router and see if the issue remains.

Okay, so connected the wireless router sent by SSE but same issue remains
Don't where to go now, so will just have to live with it I guess.

Have you tried a different telephone handset?

Thanks for the suggestion BatBoy. Tried today with single wired handset as existing setup is wireless base station plus 3 handsets.
As soon as I disconnected the existing handset base station the internet was disconnected and then reconnected after about 20 seconds. Waited until internet re-connected and once I had connected the single handset the internet disconnected and only connected again after about 20 seconds , so same as before. Did a trial call with the single handset and issue is just the same, so have reconnected original base station !!
