Hi

I upgraded to Archer MR400(EU)_V3_20190730

• Can I upgrade to V4.2?

• Also the system time returns to default date 2016 after rebooting, it doesn’t save time. any idea what is the problem.

• We have a problem with one router doesn’t detect the sim anymore? We sent the router to the shop maintenance.

What is the solution?.

• Why suddenly the router turns into 3G although we have configured the router to use 4G only.

• Everyday the routers doesn’t detect the sim, we have to reboot it to work

Thanks
