Model: Archer MR600

Hardware Version: V5

Firmware Version: 1.1.0 0.9.1 v0001.0 Build 240715 Rel.60489n

Hi Community,

I am using a 4G router (Archer MR600) and am currently unable to upgrade its software. No updates are showing via OTA so far.

Below are my device details:

Firmware Version: 1.1.0 0.9.1 v0001.0 Build 240715 Rel.60489n

Hardware Version: Archer MR600 v5.8 00000001

I would appreciate any help in finding the latest firmware version (beta or stable). If possible, please share a valid download link so I can update my router.

I am encountering the following error during manual upgrade: Error Code: 4503 – The uploaded file was not accepted.

Thank you in advance for your support.

Best regards,

Arun Kumar
