Hello everyone!
The current driver found on OpenWRT Master is based on the Realtek release 4.3.14
But there is a more recent version available based on the Realtek release 5.6.4.2
I want to help updating this driver to the latest version as this driver is a off-the-tree driver.
My intention with this is to be able to use a TP-Link T2U Plus WiFi dongle to "upgrade" my router with 802.11ac on the cheap.
The first roadblock is the driver's version: my device is not supported by the driver packaged on OpenWRT.
The second roadblock (for me) is that I am using a TP-Link WDR4900 based on mcp85xx PowerPC archtitecture. The driver (5.6.4.2) has been tested on x86 and ARM, but not on PowerPC. I believe the current driver present on OpenWRT provided by Ben Greear is compatible with MIPS architecture.
Thanks for reading this post. Cheers!
