[edit] Upgrading DD-WRT

Use the file named tplink_archer-c7-XX.bin (where XX is the version number). Do not use this to go from Stock to DD-WRT. Firmware files can be found here: Where do I download firmware?

Upgrading can usually be done via the dd-wrt web interface. Reset to defaults is recommended if you are upgrading from a very old build (> 6 months). Do not restore a backup from one version to another version of DD-WRT.

[edit] Revert to Factory Firmware

A reversion file to go back to factory firmware is in this thread [2]

[edit] AC Channel allocations

A graph of AC channel allocations is here [3]

A discussion of AC frequencies and setup of them is here [4] The 5Ghz AC radio will work at the default AUTO settings but this may NOT be optimal for your environment and you may not get the highest wifi speed on your clients. Information on this radio is here [5]

[edit] 5GHz Support on v1 (not supported)

Dd-wrt does not support the 5ghz card on the archer c7 hardware version v1.1. For old versions of dd-wrt after installing dd-wrt you must turn off the router and remove the 5ghz card or the router will brick. The 5Ghz radio works fine in hardware version 2 of this router. It is possible to remove the 5Ghz card from an old broken laptop and install it in the hardware version 1 of this device.

[edit] Recovery Information

Most TP-Link routers have a built-in TFTP client looking for a specific file name served by a TFTP server on 192.168.0.66
