Hello everyone,

I own two TP-Link Archer MR600 routers.

Yesterday, I installed the new firmware on both routers, and immediately, they stopped connecting to 4G+ consistently. Before the update, they were working perfectly. Now, the 4G+ light turns on and off at long intervals, whereas before, it was always on.

This significantly impacts the efficiency of the connection, causing noticeable speed fluctuations.

I tried downgrading the firmware to the previous version, but it won’t allow me to perform this operation.

I was hoping to get some information about this issue and to know if anyone else has experienced the same problem.
Thanks!
