Guide on unlocking TP-Link Archer MR200 from your carrier

Okay, but it still says it is disconnected what can cause this?

The data sim works no problem when I put it in my tablet.

Please open a separate topic if you have problems connecting.

i have mr200 v1 with latest openwrt installed and unlocked modem. modem firmware version is 1.0.0 Build 17/07/31 09:20:12 Rel.27n OFR

what is the latest version i can use for this modem? i am trying to fix connectivity issues and i hope new firmware will fix it. i have huawei e5577 and it works much better with the same ISP and the same conditions. does it make sense to try another modem firmware or will it be a waste of time?
