I am pleased to let you know that the thread SNR Margin and Line Attenuation - What do they mean? ranks top in Google search for the keywords "SNR Margin" or "Line Attenuation" plus the two phrases together.

Similarly, here are a few top ranking threads:

Setup of UT-300R2 with Linksys WRT54G
How to set TCP/IP setting
Setup of UT-300R2 with Netgear WGR614v7
Solution for multiple machines connecting to same BB connection - TOP RANKED

If you note that I used very generic keywords for serach - those that any average person would use.

I have searched only my own articles as of now. But I am sure that there are plenty others that also that are ranked top in the SEO rankings.

p/s. I am not trying to brag
