We're on fibre with the added speed boost, and previous had a nice and stable connection at ~80Mb since upgrading.
A couple of weeks ago, the local area suffered a flash storm during the day (hail, thunder, lightning -- very fun) that lasted about 30 minutes.
During that time, the internet connection dropped completely, and remained erratic for a couple of days afterward.
Since then, the speed has capped at 24Mb.
It's been stable for 14 days so far, so I've tried powering off the router for 30 minutes to see if a resync could be forced. No joy, though.
Could you check if there are any artificial caps on there and lift/switch to fastpath if possible?
Here's the current router readout after reboot:
I'm sorry to hear this.
The line test hasn't detected any faults but the line is in sync at 23.5mb.
Do you have a different router that you can test with? Is the router connected at the test socket?
Just the one router, I'm afraid (TalkTalk HG633).
We don't have a test socket in the property, but on moving the router to the main socket (hallway) the sync speed is the same.
In the first instance, nothing about the setup changed at all. It was 80Mb, there was a storm, now it's 24Mb after the connection stabilised.
If it helps, there were no other effects during the storm itself. We didn't lose electricity or anything like that -- only the internet went down.
