GL E750V2 - No Internet

GL E750V2 - No Internet

Developed a 'no internet' issue after it was turned off for a few hours.

I have already wasted several hours trying to rectify the issue:

Reset fw more than once
Tried manually different upgrading fw, including legacy.

I am about to throw this trash in the bin. Easily the most useless device I've purchased in the past 10 years.

UPDATE:
Issue resolved after updating from a "legacy" version of the fw to the oldest available "stable"

Can the sim card dial properly?

Yes. The sim card is fine.

I'd like to know how this happened, considering no settings were changed by me in the time the device was turned off.

Do you have a picture?
Nothing. I don't know what happened

I did not take a picture. It simply had the "No Internet" message under the name of the service provider. I've seen the message before but this time it was there for hours after I restarted the device.

I had already used the 'WAN' setting fix as advised by members of this forum.

There are many reasons why there is no Internet
Can you share the device so I can check it remotely?
