WIFI crashes after one minute of use

Good day all,

I own a GL-E750V2C6 router and I found that once the router boots wifi is shown but after 1-2 minutes it crashes and can not connect to it.

When I try to upload the new firmware wifi crashes and does not allow me to do nothing.

I have tried to upload the firmware via Uboot connecting the router via ethernet to a switch and the laptop via ethernet to the same switch but there is no communication between the two of them even having the right network configuration.

At this time I got a brick that I can not use. Any ideas?

Can’t the PC access the E750V2 directly through the lan port?
If yes, export logs

Good day all,

I have been finally able to update the firmware to latest version. It seems you must use ethernet adapter provided and not a generic usb one.
