Refurbished T-Mobile RT-AC68U Dual-Band Gigabit Router US$48 + $15 to ON

Given how old the router is now and for the final price once you add shipping and exchange I would just try to find a local comparable option instead.

Took a lot of troubleshooting and trying several methods (not reliving it, so I'll be of very limited help unfortunately) from the bay area flashing webpage, but successfully flashed John's ac68u fork.

New 8s in quotes because they stopped making these years ago and it's likely all old refurbished stock.

Code: Select all

nvram get clkfreq
cat /proc/cpuinfo

The first one will show what your CPU clock frequency is set to. The default should be 800,666, unless you overclocked the CPU, or the CFE contains the clkfreq settings. The second command will show your BogoMIPs. If it dropped to 199, you might need to test the OC settings on an older firmware version, and then permanently set the change if the testing is successful.

To do that, you need to run the two commands below.

Code: Select all

nvram set clkfreq=1000,800
nvram commit && reboot

You have the option of setting the clkfreq to 800,666, 1000/800, 1200/800, or 1400/800. The higher you go, the more likely you'll run into stability issues, and reduce the life of the router. 1000/800 is generally a safe setting to OC to. Make sure you test for a bit before you make the change permanent, otherwise you could brick your router.

Run the following commands to make the change permanent:

Code: Select all

nvram set asuscfeclkfreq=1000,800 && nvram set asuscfecommit=1
nvram set clkfreq=1000,800
nvram commit && reboot

I have a TM AC1900 converted to AC68u and running Firmware: DD-WRT v3.0-r44467 std (09/24/20)

Is there an easy way to overclock it since you first posted ? On DD WRT, I can see under administration an option to overclock now but only says 600 / 800
Why? I recently turned on QOS to avoid bufferbloat. Bufferbloat is gone but internet speed drop down from 150mbps to 100mbps and I thought overclocking may help

(S)he should be able to use the same stock commands to overclock (unless the values are not defined in the firmware).
