That would be extreme, but still possible especially if one or more are using split pairs.

I have one neighbour who causes me a loss of almost 10 Mbps when their modem is running - fortunately I am still up at 79.999 sync so there is no effect.

It could even be a line fault - but we haven't seen stats so have no idea what the line is synced at and we haven't seen speed tests so can't comment on them either. It appears all we can do is guess without any solid facts.

Split pairs in the tie pairs are fairly common, especially if the DSLAM has been subject to a knock down and resell and hasn't been rebuilt adequately

BT say no to line fault, however in my experience it's never a line fault, its always reaching your property flat out and its always your equipment or dodgy wiring etc.

So the TB line tests look a bit better, however the experience doesn't reflect that, trying to load up this to reply I was facing a black screen and looking for the wind up handle on the side to help speed things up.

What stats from the tests do you need exactly, anything specfic

So, what are your line stats?

Where are the wired speed test results?

If you want help, provide some detailed information for people to comment on.

Indeed, my thinking is more towards wireless interference and using powerline adapters aren't helping either.

I've tried it too with losing the powerline adaptors, i will point out that it was only one at the router to feed I guess and one at the BT you view box.

Is there a way to check for interference or eliminate it, I have head BT routers are garbage but I have seen it perform well wirelessly in the past.

Yes, provide the information we have been asking for. Line stats, speed test links on TBB (direct links to the speedtest), speed tests from various devices, file transfer tests on the internal network, etc. Each of those things has the potential to point us to where any issue may reside but without them we can't help you.

At the end of the test there is a Results Page button, click that and then copy/paste the link into a post on the forum.

No need to retype anything.

Checking for interference

Direct Ethernet test via a LAN port on the home hub (a) with other kit connected (b) with all wireless and power line kit turned off

Can you do some speedtests on ThinkBroadband for both wired and wireless and post them here (direct links to them rather than just the single result)? Are particular times of the day worse than others (ie do you get good results in the morning and worse in the evening)? What speed is your router connected at - does your router stay connected consistently or do you see disconnects)?

Homeplugs can also be prone to interference depending on the environment in the premises so speeds could be variable and ideally you would also do some tests from the home plug as well to see if they are performing properly.

If you have a couple of devices (preferably windows or mac) then you could do some file transfer tests between them which will tell you what your network speeds internally are like.

Wired - https://www.thinkbroadband.com/_assets/speedtest/but...

Then I got a good wired one that was 57/17 followed by a horrendous wired one at 1.4 DL and 3.4 UL...I think but there is referden to TBX and burst etc, all double dutch to me.
