Setup TPLink AC1750v5 with DD-WRT

Now the first step is to transform the firmware from TPLink factory version to DD-WRT version.

Your first need to login into your TPLink router.

Look for "System" section where you get firmware upgrades.

Now upload factory-to-ddwrt.bin firmware first. It will take some times and do not do anything until the it is completed. Otherwise, you will brick it.

Once done, you would not need this factory-to-ddwrt.bin firmware anymore.

Once done, you need to do a complete hardware reset (using the pin holds for ~12 seconds). This will change the interface into DD-WRT. It's default location is now: 192.168.1.1.

Re-visit the router login page. You'll be greeted with setting username and password. At this point, set it to something simple and dummy as we will need to update the firmware.

With the DD-WRT ready, it's time to update the firmware.

Now upload the 'tplink_archer-c7-v5.bin' firmware. It will take some times.

Once done, you need to do a complete hardware reset (using the pin holds for ~12 seconds). This will change the interface into DD-WRT. It's default location is now: 192.168.1.1.

Re-visit the router login page. You'll be greeted with setting username and password again. This time, set a proper and secure username and password.

Once done, your DD-WRT TPLink AC1750 is ready.
