Had a problem with my broadband recently,100ks instead of 3mb, and the technical information being bandied are way over my head. In my experience I like to do simple things first. Change Filter and Router with neighbours working unit for comparison.
On talking to my ISP ( TalkTalk ) was asked to do a couple of things, to determine where the problem was (from master socket)
1) change ISP username to bt_test@startup_domain and restart router.
2) open browser and type in
http://www.bt.net/digitaldemo
The webpage did not load showing a bt fault. Which they dealt with.
3) Went to
www.bt.com and loaded line fault check. This showed a line fault near house. Found to be a intermittent connection.
It may pay to change to another provider as, I believe, changes will need to be made at exchange and this could also be cause.
I will not use LLU as I wish to keep line with BT, this is preference only.
Of those you list would use Talktalk, unless you have sky tv.
I use TalkTalkBusiness (nonLLU) can be slow at night sometimes, as with all providers on exchange.
This has good information
