Hi, thank you very much for the message.

1.0.0 3.0.0 v60e0.0 Build 250411 Rel.56555n is a customized version specific for the local Malaysian market. The actual hardware is Archer NX200(EU)_V2.2. The official and beta versions are all for standard V2.0. So you already have the latest firmware installed. 

Best regards.

  @David-TP The current firmware came installled on the modem I bought, so I dont know where it originated from. And yes, the error msg popped up when I tried to install any of the v2 firmwares from TP-Link downloads.

Hi, thanks for the update.

Is the router provided by your mobile service provider?

I didn't find this version anywhere else in the database, and think it might be an ISP-customized version.

Would you please leave me a message with the MAC address of this Archer NX200(EU)_v2.0?

Wait for your reply.

Best regards.
