We have been experiencing slower speeds and some occasional disconnects with our Home Hub 5 for a little while. This seemed to get worse towards the end of last week - at one point I was disconnected three times during the course of an hour while trying to talk on a Google Hangout. As a result, over the weekend I tried some of the methods suggested to fix connection issues, which included restarting and resetting the router. By Sunday, I figured out that this was probably a bad idea as I learned that repeated disconnects like this can simply result in the connection being placed on a banded profile.
The speedtest results from the speedtest.btwholesale.com tester certainly indicated that the connection was being artificially limited, with an IP Profile of 0.25 Mbps and upload speeds actually slightly higher than download speeds. From reading around it seemed that the only way to get taken off banded profiles was to let the connection stabilise and that it would automatically improve over 3-5 days.
Unfortunately, the disconnections didn't stop and the hub has disconnected at random points at least twice during the course of the week. It managed over three full days of connection between Tuesday night and last night, but when I checked this morning it had again disconnected itself during the night. Not only do I not know why this is still happening, I also assume that this is preventing the banded profile from being lifted.
The line in the event log that shows up explaining the disconnection is "", which from reading around here seems to be a result of BT trying to make configuration changes to the hub.
I have also since tried the line noise test by plugging a phone directly into the master socket, and couldn't really hear anything between the messages. The noise margin seems on the low side from what I can work out but I'm no expert with these. Similarly, I have run the speed test again and while the IP Profile has changed very slightly to 0.31 Mbps, that's still obviously giving me incredibly slow speeds, and the tester doesn't seem to think there is anything wrong.
Can anyone tell me if these results and router stats indicate a specific issue that needs to be fixed? I believe I have tried everything I can do here to diagnose and/or fix problems and none of them seems to have worked. If it was simply a case of leaving the connection until the banded profile was lifted, I'm not sure how that's going to happen if the router disconnects of its own accord every two or three days.

Solved! Go to Solution.
So I've waited a month and while the speed has increased very incrementally, the IP profile on the line is still just at 1.15MB and clearly hasn't made it back to full speed, making many things unusable. Is it going to get any better than this or are we stuck at this speed now it's been a month?
We are now also getting constant messages on the event log suggesting a TCP reset attack starting like this: " OUT: BLOCK  Packet invalid in connection (tcp reset attack is suspected"and then followed by "IN: BLOCK  Packet invalid in connection (Invalid tcp flags for current tcp state: TCP". I've seen posts saying this is just the firewall doing its job but is it really normal for that to be happening every time any traffic passes through the router?
@DariusA We'll be happy to look into this further if you send over your details on the 'click here to contact the mods' link in my forum profile. You can find the link by clicking on my username.
The block TCP blocked packet messages are normal and nothing to worry about as you've seen it's the firewall blocking unauthorised access to your Hub.
I can't see that link appearing anywhere on your profile - I've searched the page several times now and only the regular BT contact pages are appearing, nothing about contacting the moderators. Is there something I'm doing wrong?
Hi @DariusA Sorry about that. I have enabled the link for you under my profile. You will see a click here to contact the mods hyperlink just below my Avatar.
Ps you will not see the link on the mobile view setting.
