Hi there,
Currently, the network card issue of the GTR9 395 persists, and its root cause lies in the Ethernet driver.
As of now, there is no new driver available to resolve the disconnection problem of the Intel E610.
The current workarounds are as follows:
Perform a physical power-off and re-plug the power cable.
We suggest you to to use a Wi-Fi connection instead. Or you can buy a USB to ethenet 1GB dongle(About 5 USD) .
A complete resolution to this issue will only be possible once a new driver is released.
