Dear all,

I have one problem with one AV500 powerline adapter. My internet connection is 200/20mbit and I have powerline from the router to my bedroom. I know that the devices that I have only have 100mbit on the Ethernet port, so I know that I will never get the 200mbit speed.

But that is not the problem! I have the powerline setup working, but in my bedroom if I connect a ethernet cable to my AV500, I can get 85-90mbit speed which is good and it's more or less the expected. The problem is when I access the AV500 with wi-fi...

Even with my laptop right next to the AV500 device, the maximum speed that I get it's around 45-50mbit. I am using wireless channel 11 in 40Mhz band and N norm... I have already changed the wireless channels and the band to 20Mhz but the problem remains... I cannot get more speed than the 45-50mbit accessing the AV500 via wi-fi.

I really do not know what is wrong because if I just plug an Ethernet cable to the AV500, I get the 85-90mbit...

Does someone have a clue on this?

Thank you
