Apologies for the long post....
Usually I enjoy a sycn rate of between 6.5 and 7.5. The last couple of days I noticed the router rebooted and dropped to 4. Both times I rebooted and it re-synced to 7 and I carried on. This morning my netgear router was in a cycle of negotiating training and disconnecting. Knowing I would have to make a call to BT I plugged in my home hub 2 and changed the micro-filter and plugged into the test socket, sure enough the BT Home hub wouldn't connect and the broadband light kept flashing orange. Phoned BT went through the script and the fault was logged (about 10.15am). At approx 1pm the internet came back on and the sync speed was at 3.5mb. Obviously not the speed I normally get so I rebooted the router at about 1.30pm. The orange flashing light then came back on and I had no service until about 5pm then it went back to a reduced speed of 3.3mb.
I did a check on bt speed check and it said my ip profile was 2.5mb. I have read about this and I understand I need a stable connection for at least 3 days before my speed profile would increase.
My main question is I don't want the fault being cleared with BT unless I know the router will connect after a reboot. Do you think I should reboot it (and risk another four hour outage) Or wait 3 days? Assuming the fault is now fixed, and my line speed will gradually return.
