I have had the AV600s for a while now, but recently (as in the past few months) the download speed has been dropping off whil my upload speed has dropped a little but remained the same for the most part.

Both on the WiFi and wired connections to the extender are barely getting above 3Mbps down, while the upload is consistantly around 15Mbps. Connection to the router directly, both wired and wireless get around 60Mbps down.

The Utility app shows that, the speed between the PA4010 and the WPA4220 is over 200Mbps and my ethernet port is working at 100Mbps. I have tried it in mutliple rooms, pluged next to the PA4010, as well as 4 different ethernet cables, reset the entire system twice, updated the Utility on my PC and the firmware on each device, and the results remain the same.

Ive done everything i can think of and all the troubleshooting i can but cant find a solution. Am I missing something or is it a problem with my houses elecrtical system, and if it is a problem with my houses elecrtical system, why is the upload speed 5 times faster than the download speed?
