Randomly slow internet

Rich1986 — Mon, 18 Oct 2021 19:52:11 GMT

About 10 days ago approximately, out of the blue my EE suddenly started going incredibly slowly at random intervals. Streaming Netflix, YouTube, video conferencing, online gaming - even just loading webpages - would all suddenly become really slow. Then, a while later it would seem to sort itself out. This has continued ever since.

There's no obvious pattern - it's not that at certain times of the day it's slowing down...or when I'm doing a particular thing with the broadband it slows down. It just seems random - these periods of 'lag' do seem to getting more frequent, and last longer - and conversely the periods of stability seem to be getting less frequent and shorter.

Just a few extra bits of info:

I have checked on the router - there is nobody else 'leeching' - i.e. no neighbours etc are connected to my router and downloading using my bandwidth.
It is not just my PC that experiences this 'lag' - it is every device we have in the house. I have tried my wife's work laptop, my phone, a spare laptop we have, and my desktop PC. All experience the same issues at the same time. All also get the same 'scores' on BTW Performance Tester.
My PC is using an ethernet cable - the rest are wireless.
My router *was* an old style one (from 2015) but has been replaced several days ago with a SmartHub. On setting it up etc I noted that the problem seemed to resolve with no obvious issues that evening - but the following morning the problems resumed again with agonisingly slow internet.
A BT Engineer has been out to my address twice. He has removed all of the sockets in the house except for one which he changed and is now a 'master' socket that has some sort of built-in filter in it. He has also done some work on the exchange and both times he has been here prior to leaving he has run some tests at my property and said we are getting about 40MB/S entering the property and he can't see any issues.
EE have run tests their end over the phone and said (as of today) it appears around 39MB/S is entering the router and they can't see any obvious issues.
I have tried turning the router off and on - repeatedly - oddly, when I do this the issue seems to pretty much vanish - but for only around 10 minutes.
I have ensured nobody is downloading anything, closed all non-essential programs on each computer and tried turning all devices off except for one and trying each device - they all have the same problem - so it's likely not the devices themselves.
Finally - I have never had this issue. It just appeared out of nowhere 10 days ago - nothing has happened - we didn't move home, we didn't spill coffee in the phone socket, we didn't alter any settings on our old/new router - we have no explanation for why this is happening.

Today I ran the BTW Performance tester at random intervals and recorded the results:

As you can see - only around 1257hours was I getting about what I should be getting. The rest of the day any time I ran the test I wasn't getting what I'm meant to be.

I spoke with EE on the phone again today and they are sending a 'Cube' engineer out Thursday morning - in honesty I don't really know what that means.

My wife relies on fast, stable internet for her work - what else can I do in the meantime to fix this? I'm pulling my hair out here.

Welcome to EE's Home Broadband Forum.

If you would like help with your BB speed or connection issues, please would you carry out the following steps for starters, which will enable us to diagnose the problem and advise you further. Do not restart your router to do these tests:

1. Post your full router stats:

For a BrightBox: login and go to Advanced Settings/ System/ DSL Status. Also post 'System Uptime' from top of System Log page.
For a SmartHub: login and go to Advanced Settings/ Technical Log/ Information. Obscure your names & any numbers in the BB Username & also the SSIDs.

Full router stats are key to any speed & connection issues.

2. Try a wired speedtest, using an Ethernet cable supplied with the router, here http://www.thinkbroadband.com/speedtest.html . Click on the "Results Page" button at the bottom of the graph you first see and then copy to here just the "Link to this result:" link that you see below the next main graph.

3. What does BT Wholesale Broadband Availability Checker estimate for your phone number? Post just the whole table and the line above it, blanking out your phone number. If it doesn't recognise your phone number or you don't have one, use the Address Checker, not the Postcode Checker.

Um,, Connection speeds are good but Upstream speedtest extremely slow & downstream TBB speedtest fairly slow.

Locate the hidden test socket that is revealed when you remove the bottom half of the split faceplate (2 screws or press tabs) of your master socket. Only do this if you have a split faceplate. Do you have any extension sockets in the home even if unused? Are there any wires connected to back of faceplate of master socket?

Try the BT Quiet Line Test (QLT), dial 17070 Opt 2, preferably with a corded phone, in the test socket with the router disconnected. If there is any noise, report it to your landline provider as a voice fault (don't mention Broadband). Often sorting out voice faults will fix the Broadband as well.

Reboot the router & plug it into the test socket. Post the full router stats & speedtest when plugged into test socket.

Is the issue any better?
