So I have checked my router internet bandwidth usage and with my 6 miners running there is not much traffic... maybe 20-30kbp/s.

My router is upstairs and it connects into an IP over Power adapter which goes into my basement and connects to the matched box in another power outlet. The ethernet connection then goes into a linksys 24 port 10/100 switch which all of my miners connect to.

I continue to see the miners perform under their baseline rated hash rates (8GH/s each). I know that the workers screen averages over 10 rounds but they are always dropping down to 4-5GH/s. When I log into the miners GUI they all say they are running at 8-11GH/s... But the rewards reflect the 4-5GH/s and not what the miner says...

Based on the low bandwidth usage I didnt think that was an issue but wanted to check and see what you all thought... Any ideas why I might be seeing such a difference?

I am using BTC Garden Miners that are rated for 8GH/s...

Thanks in advance.
