Updating the 'Cable Modem Signal Levels' sticky

[Pantsu-san]

As more and more people are moving on to 50Mb service please could some nice person please update the sticky for the newer cable modems/services (perhaps to include all tiers?) as there seems to be a large increase in "are my settings ok?" posts.

Thanks.

If someone would like to creat a post in this thread with the correct/updated information in I am quite happy to update the sticky.
