I think I solved the a7000 USB 3.0 issue... Thoughts please.

I think I solved the problem with the A7000 that turns off intermittently and also the problem with it only using USB 2.0 speeds. It seems the problem with ALL usb wifi dongles is overheating. I bel...

Windows also seems to disable the 3.0 once you shutdown windows. I had to use task scheduler to basically turn off RunSwUSB and turn it back on when logging into windows. This brings up the 3.0 speeds once again after a shutdown vs. restart.

Spoke to soon. I got a good 5 hrs out of it then it disconnected. I can't reconnect and my windows doesn't recognize any USB 3.0 ports. The port shows a triangle with exclamation point on the 3.0 USB port and it won't let me reconnect unless I restart the system. I'm going to do more digging but 5 hrs is a lot more than I've gotten in the past.

    I solved it: Purchase a powered USB 3.0 hub and connect it to that.

      Thanks Paulie!

       

      After wasting 3 days with this issue (one computer works fine with this adapter, the other one has the issues EVERYONE is complaining about - where you either have to deal with disconnects out of the box OR disable the RunSwUSB which prevents disconnects, but at the expense of consistent / high speeds).

       

      Since the adapter works fine in one of my computers - speeds of 858 Mbps without a hub with no disconnects, whereas it has issues with my other newer computer - disconnects after a while and computer has to be rebooted or adapter has to be removed), I am convinced it is a USB chipset / USB power issue and your hub solution makes sense.

       

      Which hub are you using?

        Do you think it could be down to the Windows drivers for the USB chipset? (Not the drivers for the USB adapter.)

         

        I mention that because the same thing has happened with wifi chips, no USB anywhere in sight.

         

        Windows update rarely picks up driver updates at the motherboard/chipset level. The only way to get those updates seems to be to track down the motherboard maker's site and to see what they have to offer. In some cases it is down to finding the chipset maker. For example, in the case of the wifi problems, it was Intel that had the right drivers. Another regular guilty party is Realtek, which does audio, wifi and bluetooth chips.
