Line Speed help!


[link to this post]
 
Hello everyone first off let me introduce my self my name is Allon from Northampton and this is my first post, I am hoping someone can help me?

Right about 20months ago I left talk talk broadband for virgin when I left I was getting 16-16 half Meg consistently. I have now moved back to BT lines through sky broadband and have been with them since November from the off set I have only been getting 13mb sometimes less I checked the connection speed the router itself tells me my speed is 16 odd but actual speed is only 13 odd did test both wireless and hard wired so I then changed the master socket to a MK3 added almost half Meg so some result also changed the RJ11 for a cat6 cable still no better so I thought it was something to do with the [censored] (apologies for swearing) router sky give you so went back to my trusted Netgear DGND3700 I used previously on talktalk after finally working out how to get login details from the sky router that is a pain in the bottom to! Got it all working today and still only getting about 13mb but router still says connection is about 15 half I have checked most setting on router as well so I am now stuck!

So am I missing a setting somewhere or is it just sky's rubbish please help I have run out of ideas?

Thanks in advance
Allon

Maximum throughput on ADSL2+ is about 0.84 x connection speed. So a 16% loss. Nearly all that is TCP/IP overheads.

84% of 16Mbps is 13,440kbps. Your loss of speed looks to be due to a lower connection speed than when with TalkTalk.

Can you see your attenuation and noise margins in the router stats?

Routers usually give Connection speed (sync), Attenuation and Noise Margin (SNR or SNRM) all in the same place. We could do with all three, both down and up.
