Hello, I am using virginmedia superhub which is supposed to give me a max of 30mbps. I use it wireless but am often getting fluctuations in speed - sometimes 500kbps upto 20mbps, nothing consistently close over 20mbps or close to 30mbps. I have bought a powerline kit - "develo olan 200 AV Wireless N" which has improved the speed but I still get fluctuations. Is there anything else that can help me overcome this high traffic? e.g. a wireless repeater/range extender.
