Slow Broadband after lightning strike

Hello Everyone,

 

Our BT Master Socket was fried during the recent thunder and lightning storms and after a new socket was fitted our Home Hub 4 is now showing a download speed of around 0.25 Meg - this has remained static for over four days so I have now reset the router and plugged into the test socket but with no improvement, do I still need to wait another 3 days before I can run any further tests ???? Prior to this our older master socket was giving a 12 Meg download, help!

Here is a basic guide to getting help from the community members done by CL Keith Please read through the link posted http://forumhelp.dyndns.info/speed/first_steps.html
once you have posted the information asked for then the community members can help you more

if using a hub 4 locate these lines located in the hub logs
Lines should look like this
19:11:29, 07 Nov. (2290101.460000) DSL noise margin: 7.00 dB upstream, 6.10 dB downstream
19:11:29, 07 Nov. (2290101.390000) DSL line rate: 448 Kbps upstream, 288 Kbps downstream

Re: Slow Broadband after lightning strike

Hi,

 

Sorry for not getting back sooner but have been away from home but thanks for pointing me in the right direction, hope this information helps,

 

I have run a quiet line test from the test socket using an old BT 'Vanguard' corded phone and I couldn't detect any backnoise at all

 

Latest DSL stats from my Home Hub 4

 

14:29:27, 11 Jul.(52631.620000) DSL is up
14:29:26, 11 Jul.(52630.600000) DSL noise margin: 5.90 dB upstream, 21.80 dB downstream
14:29:25, 11 Jul.(52629.680000) DSL line rate: 1129 Kbps upstream, 287 Kbps downstream

 

I found this STAT from the WAN log, prior to the thunder and lightning!

 

12:37:00, 28 Jun.(82641.460000) DSL noise margin: 5.90 dB upstream, 6.00 dB downstream

 

Finally from the BTW performance test

Re: Slow Broadband after lightning strike

Due to the previous disconnections you have ended up in a banded profile.  You now need to maintain connection 24/7 for 3/5 days and banding should release automatically

 

however if you get 3+ days connection time the repost your 2 lines of stats and mods will help get you out of the banding

Re: Slow Broadband after lightning strike

 

Hi everyone, my broadband has improved considerably with a stable connection for over 5 days now and below are the latest stats from the BTW performance test - my question is the download speed was around 12.5 Meg max. before the elements struck so I am still not quite where I should be in terms of speed, will my IP profile update again soon or does something else have to be done, many thanks

Re: Slow Broadband after lightning strike

Your profile is based on your connection speed so to get higher profile you need faster connection speed. Can you post the 2 lines of stats from the router logs - is noise margin still higher than normal 6db

Re: Slow Broadband after lightning strike

Your noise margin is still high so just stay connected and noise margin will continue to reduce in stages down to 6db with corresponding speed increases

Re: Slow Broadband after lightning strike

 

Good news, that's most reassuring, just for future reference if this happens again - is resetting your router several times for a couple of days one of the WORST things to do if your broadband speed is slow when you are reconnected!!!
