      Low upload speeds

      Coulpd anyone please help ive run speed tests on numerous sites and it seems that my upload speeds are qiute low. The download speeds are fine i average between 6000kbps to 8000kbps but my upload speeds are always below 300kbps. Is this a major problem, ive posted some results my line attenuation and noise margin looks fine i think? Any information would be most appreciatied. Thanks, Steve

      Re: Low upload speeds

      With your quite low attenuation you should be seeing a much higher noise margin on Mid. This suggests you have a fairly noisy line. Line noise leads to data errors and corrupt data has to be retransmitted. That means lower throughput.

      If line noise isn't the issue (but you'd benefit from improving your connection in any case) then maybe your PC settings are incorrect. See the second sticky in my signature.

      If neither of those things then run an up to date virus/malware scan as low upload can be an indication of something nasty on your PC using the bandwidth. If you ( or someone else on your LAN) are using Sky Anytime or the BBCi player etc then you'd also see this.

      Re: Low upload speeds

      Thanks saturday i have run this before, but i run it again has you advised and it does not make much different to be honest. I did do a Virusscan on Saturday and everything was fine. I do have a extension cable from BT my master socket to my PC that is 10m long will this have any bearing on the results. Having a low upload speed is this a problem. Thanks, Steve

      Re: Low upload speeds

      Yes, plug in extensions are always bad news.

      It could well be line errors which are causing this small decrease in your upload speed, particularly if the noise is occurring in the frequency range used for the upstream.

      However, to get things in perspective, the protocol used to transmit the data has an overhead of ~20%. So for your upstream sync of 416kbps you'd expect to see an upload speed of ~332kbps. You're getting 278kbps so the shortfall, whilst bad, isn't ridiculously bad.

      Are there any other users on the LAN or any background internet using software on your PC? Also, don't rely on a single virus scan to check. Personally I'd suggest using a free on-line scanner that also looks for rootkits such as f-secure to be sure. Also, something like Ewido or Ad-aware.

      There's probably nothing to worry about but better safe than sorry.

      I may be wrong, but I don't think it matters too much unless you are doing a lot of uploading, such as servicing a website.
