My experience would advise that performance will depend on the actual router it is connected to. Also for some reason on the Cisco/Linksys and Netgear routers that I have done this with seem to only be reliable if using a 3.0 powered drive like a 2.5 inch portable drive. It seems that most of the larger 3.5 external drives will spin down to save energy and that causes the OS in the router to lose connection with the drive controller. Even updating the firmware has not solved that on some Netgear routers. Other users may not have that problem but my recommendation is to only use a smaller 2.5 drive powered by the USB 3.0 only. The best results for storage connected to a router is probably just a flash drive. If you need more than flash drive size you are probably better just buying a network or NAS drive and not using a USB connection drive.

Yes.

yes workks on any wifi network ive tried

This is an internal drive. It doesn't go through a network. The interface is SATA not ethernet or wireless

My computer automatically detects and connects

Go to your disk manager and see if it shows up there may have to initialize the drive and give it a drive letter. And go to yor device manager and see if even showing up in there.
