Slow Broadband Speed (I suspect banded profile!)

Hi,

 

Right here is the story. My broadband speeds have always been ok. (roughly 5-6 Mbps down) I get an email saying there will be work done on my exchange and it might make it faster. The work goes on my router loses connection for about 30 mins then comes back on. Wow! 15Mbps down more than double speeds! Works fine all that night.

 

Next day I can't connect, look at the router and it is in the process of booting up. Check logs it went down again for about 10 mins (I'm using the Netgear N600) Weird, just think it's teething problems but this happens randomly all day and the next and the next. I'm getting annoyed so I switch back to the Homehub3 and this starts dropping connection too. So I change every filter in the house which seems to sort it out. However speeds are now real slow! So I test it using the BT tester, on the master socket with a wired connection (https://dl.dropbox.com/u/2206810/bt_speed.png) Poor speeds and speedtest.net is saying the same. This looks like its now a banded profile.

 

So I left the Homehub in trying to keep a stable conntection for 3 days but it won't the little timer seems to randomly reset even thought the logs say it was last powered up on the 13th. The connection hasn't improved so I turn here for help.

Re: Slow Broadband Speed (I suspect banded profile!)

until your connection time on your hub the banding will not lift and nothing can be reset until a stable connection is seen

I have a stable connection but it never gets to three days. It will reset at about 2 days. This banded profile things is rubbish and it's a ripoff. Restricting a service I'm paying for!

Re: Slow Broadband Speed (I suspect banded profile!)

it happens because your line is unstable have you tried connecting your hub to the test socket and see if it improves then

My test socket is in the hall with nothing to put the router on. Can't leave it on the floor, the 2 kittens will tear the leads to shreds!

Also why doesn't homehub3 record a disconnect in the logs? It's a **bleep** useless router!

Re: Slow Broadband Speed (I suspect banded profile!)

it does show disconnects 

you need to connect to the test socket to remove any possible internal wiring errors also  if an Openreach enginner is needed  and the fault is found on your extensions the visit will be chagable

Re: Slow Broadband Speed (I suspect banded profile!)

Ok well in that case my router must have been up more than three days. Even though that little timer has reset...

 

Here are my logs. The entries before are from April last year. That is when I swapped it over for the Netgear. You can see no disconnect entries at all. The dropdown box is set to all.

 

Do I need to re-start the router to get rid of the speed cap banded profile? Also should I turn off the auto-channel selection? It seems to have selected the exact same channel as my neighbour anyway.

Re: Slow Broadband Speed (I suspect banded profile!)

no restarts are the cause of the banding and why the stable connection is vital the connection time is the only acceptable time is the one from the hub stats yes by all means go to manual channel selection it will not improve the connection stability that is why the connection to the test socket is important as it is a direct connection to the exchange

So its restarts that aren't recorded in the logs then?

Re: Slow Broadband Speed (I suspect banded profile!)

yes they are as PPP disconections you will also sew the reconnect speeds and noise margins in the log
