Acceptable power levels?
 
Having had a stable 20Mb connection for a few years (albeit with a 12dB attenuator attached to my modem), I've just hooked up and activated my Superhub and am having a few stability issues.

Now, I don't know if it's because i've literally just activated it (within the past 30 mins), but it's up and down like a yo-yo at the moment.

Can't seem to find power levels relating to 30Mb peeps, but do levels below seem acceptable?

(Sorry for the dull question - i'm just wondering whether or not I need/should take off the 12dB attenuator, as the 30Mb might benefit from it?!)

Thanks!

Powere levels are the same for all tiers pretty much and those levels are basically perfect :)

Ah that's good then - i'll leave the attenuator on :D

Annoying how i'm constantly dropping offline though :(

Nothing useful in the hub eventlogs either

Actually having a second look at it your SNR levels are a little low especially on the second channel, but there near enough the same as mine and mine works fine
