| Install if: | Avoid if: | |----------------|----------------| | Your WR850N v3 disconnects daily on Indian ISPs | You have a newer router or plan to upgrade soon | | You understand TFTP recovery (brick risk) | You need >100 Mbps or 5 GHz Wi-Fi | | You cannot replace the router right now | You want official, easily downloadable firmware |
Final verdict: The “India fixed 2021” firmware is a legitimate stability patch for a legacy router. It solves major ISP compatibility issues in India but does not modernize the hardware. Given that TP-Link has stopped supporting this model, consider this a temporary fix – not a permanent solution.
