Following on from my previous post here...
I have now moved house
My sync rate is 1.688 Mbps This is despite being so close to FTTC. I expect the fact the copper lines rub up close to a shed load of trees by a local forest doesnt help much.
Here are my precise stats at the moment...
Searching around for a way out of my broadband woes I discovered that my exchange is enabled for ADSL2+
This was the bt search using my phone number.
Available ProductsDownstream Line Rate(Mbps)Upstream Line Rate(Mbps)Downstream Range(Mbps)Availability Date
|WBC ADSL 2+||Up to 7||--||6 to 12||Available|
|WBC ADSL 2+ Annex M||Up to 7||Up to 1||6 to 12||Available|
|ADSL Max||Up to 4||--||2 to 6.5||Available|
|WBC Fixed Rate||2||--||--||Available|
I think I am on ADSL max given my current modulation. My question is - would asking to be moved to ADSL2+ make any significant difference given the attenuation on my line that is apparent from my stats? Or is it like to be just as bad?
Solved! Go to Solution.
with a 50 attenuation I would expect about 4.6mb connection speed on adslmax and about 4.7mb on adsl2. at present the noise margin is high at 15 either due to line noise or manual resets or both. I would suggest you try and improve your current connection before trying for adsl2 which is far more aggressive on line noise
are you connected to test socket? is quiet line test ok?
infuriatingly I can`t find the master socket. It`s not where it usually is. It`s a bungalow built in the 1970s so I guess the wiring is probably fairly old. What is a quiet line test though?
dial 17070 option 2 should hear nothing and best with corded phone if cordless then dull hum normal
if you can see the incoming bt wires then master should be where line enters your home sometimes can be in attic
Thanks for that tip- heard a quiet constant hum/crackle using a corded phone. I`m guessing that`s not a pass. I`ll have a hunt for the BT lines entering the house tomorrow -not looking forward to a crawl round the attic though. I wonder how much tree interference along the roadside is contributing to noise compared to my internal wiring. I guess sorting out the latter might answer the question. However if the master socket is in the attic I`m not really going to be putting my router up there...
if you can hear noise on your line then you need to rport a phone fault to 151 with no mention of broadband. get noise fixed and that will help your broadband.
I realise if master in attic then you can't leave router there but check for the bellwire as described here
phone 151 - that sounds too easy to be true! Are they really going to send someone out because I report a dull hum on my line? If so, fantastic, but I`m wondering how do they fix that kind of thing? Won`t they just tell me to get better extensions wired up?
thought you said a crackle as well? see if you can find master and remove bellwire from all sockets and see it that helps your connection. need to get noise margin down to the norm of 6db to get a better connection speed
crackle/hum it`s all the same to my untrained ear. I`ll try to root around the attic this weekend, or maybe chop a few hundred tree branches down along the line route to the cabinet!
with a corded phone there should be no noise on the quiet line test - any noise will have a bad effect on your broadband connection and may be reason for high noise margin. has your connection been dropping or have you been manually resetting the router to try and improve your connections. resets are the worst thing for your connection
