Good levels mean a good experience. ;)
Interesting article. My levels seem to be nicely within the stated ranges. 8)
I found it helpful as well. Within ranges. However, I have a splitter on my Cable Modem that I COULD remove as I no longer have Cable TV, but I can't remove it because Comcast put a locking collar on it that you need a special $5 tool to remove. That would give me a bit more kick.
Pretty cool. Never been able to log into my modem before finding the address on the linked page. Thanks!
I didn't check what the signal level was, but I installed a signal booster and it changed my packet loss from a few % to 0 (using pingtest.net)
