Hi @bhall ,
If there was a fault on your line then it could possibly take a few days for your speeds to improve once the fault is fixed. OpenReach should 'reset' your line after repairing a fault, which should immediately get your speeds back to normal, but if they didn't do that it may take a few days for the speed to increase again. Leaving the router switched on 24/7 is the best thing to do to help your speeds improve.
However, if there is still an issue with your connection the the staff on this forum will be able to help.
For one of the TalkTalk OCE's on this forum to be able to look into this you will need to update your community profile to include your name, landline telephone number & alternative contact number. This will allow them to identify you, and they will then be able to check your connection.
Don't post any personal details in this thread, just add them to your community profile.
The TalkTalk staff on this forum probably won't be around now until Monday, so it is unlikely they will respond to this thread until early next week.
I've completed a line test which hasn't detected any faults.
Please can you connect the router at the test socket and then power down the router for 30 minutes so DLM can start monitoring the connection in this set up?
