SNR Problems.

My SNR is way too low. I read online it should be at least 12db, and mine is below for upstream and downstream. I cannot play games, it takes about 2 minutes for videos to start streaming. 

 

How can I sort this out?

 

(Yes, i've tried restarting the router. The slow connection also isnt being caused by my wifi at the moment, as I have had command prompt keep pinging my router and all is normal)

Re: SNR Problems.

Where do people find this rubbish that says the SNRM should be at least 12 dB? Possibly on the TP-Link website, but I can't find the exact page right now.

The standard target SNRM is 6 dB, that should be fine for most lines. Even some of the longer lines can work OK at a 3 dB margin.

Edit: Found a page which warns about SNR margins less than 10 dB.
