Flint2 wireless settings

Hello, after upgrade to firmware 4.5.7 on Flint2, wireless has become very unstable. And I cannot reach the wireless section when logged in the router. I keep getting the following error:

“Unknown error occurred. Please check the network environment or reboot the device.”

Any input is greatly appreciated, thank you.

Please do a factory reset to restore all settings and try again.

Depending from which version you upgraded (maybe some beta?) it could be possible that the Wi-Fi settings crashed.

Thank you for the response. I factory reset the router firmware and it appears to be working normal now.
