keep losing connection and speeds half

Stratoc1 — Sat, 13 Sep 2025 13:09:49 GMT

Hi, my speed dropped from 64 mg to under 30 Wednesday, disconnected router for 30 minutes, re connected it all was fine. I then ran a line test on Talktalk website and got a text saying please contact us, as connection was fine I didn't. Last night I got a text saying Openreach have found a problem with your line and ETA for fix is tonight. Followed by one saying it was fixed.

Next morning I noticed the wifi was missing from my phone and red light flashing on router, it reconnected at about 57 meg so I assumed that was okay.

Was fine all day, been working this morning and lost connection again, reconnected at just under 30 again? Any ideas?

I ran another test and it says they have identified a fault and there is a chat now button that doesn't do anything?

Thanks

Please can you elaborate by answering these few questions:-

1. What make/model of router do you have (if this is a TalkTalk router, these details will be on a label on the rear or underside of it)?
2. What package are you on? If Fibre 65, is this Full Fibre or FTTC & copper wires to the property?
3. If you have any wired connections, are they affected in the same way as wireless ones?

Hi Keith

Sorry, I'm on Fibre 65 FTTC. and I have a TT router FAST5364 3.00. on SG4K100208.

My PC is wired, laptop phone and firestick on 5gz.

I have been using the filter for over ten years so will hunt down a new one when I get home, Router is only a few months old.

Is the varying speed test via the PC or all devices? If you log in to the router when the speed is low, what speeds are shown in the top left of the initial dashboard of the router's UI?

it's on all devices , a quick reboot of the router returned it today, so lost connection, reconnected straight away at 28 meg, I rebooted the router and it was doubled and been ok since, for a bout an hour

If it goes slow again, please log into the router & chack the speed there.

It was the router I'm quoting from. /Will do, it's actually been stable since, but was from last night until about lunchtime today.

Thanks for your time, I'll keep you updated.

Hi there

I put a new microfilter on after posting on here and it's been fine since. Not really sure if that's related or coincidence. Three times in the last week it just lost connection went through the reconnecting straight away but was literally half speed on the router log in, speed test and even the Talktalk service page which had a red ! on speed, all three times a manual off on with the router put it back to normal speed.

I can work out when it happened because on the router log in the system up time is greater than the connection time.

Today system up is 1day 20 hours and 24 minutes, exactly the same as connection time so all looks good.

Hopefully one of those things.

Thanks both for your help

Often switching the microfilter can be enough to resolve an issue.

Please let us know if you continue to have problems with your service.

well, it wasn't the filter, had a few lost connections since last connection is 8 hours V 3 days system up. would really be helpful if system logs worked

Re: keep losing connection and speeds half

KeithFrench — Wed, 17 Sep 2025 10:24:38 GMT

Yes, I agree @Stratoc1 about the system log. I highlighted this to TalkTalk immediately I found this out with V208 and, like you, I am waiting for the next firmware version.

I can't remember if the line has been tested for intermittent faults? @nambuso-TT can you advise on this issue?
