Hi,

I'm on the VM 50mb broadband, and although I get full 50mb on speed test the web browsing seems a little laggy.

Could it be anything to do with my upstream power levels being too low? Also, my SH2 co-ax cable has a (forward) 20dB attenuator as my property is very close to the cabinet and the tech used one of the higher taps.
