Hi.I think the power will loss after you use 10m USB cable on MR3020.So MR3020 can't supply enough power for the modem and it will show modem unplugged.It would be better to put MR3020 in a place...

I have a M5350 hardware version:V1.The total data will reset to 0 automatically after usings about 4GB. I consulted TP-LINK and they told me M5350V1 is 32 bit traffic counters.It max support 4GB data...

Once I want my WiFi of M7350 always on.So I go to manage page and I found in Advanced--Wireless option.I can set WiFi auto disable time to 0 and WiFi will not auto off. Hope this can help you!

You can try to delete the default 8/35 Bridge item.Then enable UPnP.Maybe it can help.

Hey,Guy!You use wired or wireless connection?You can try wired connection and run speedtest.Then check the result.:)
