I would suggest setting up a separate thread as it's not related to this topic, maybe raise it in another forum all together.   Having said, I tested it with USB3 memory stick and it works fine with no special configuration. Perhaps it's compatibility with your external device (eg. maybe the router can't supply enough power). I suggest trying with memory stick to check it's not your USB port that is broken.     ...

@mpsmart87 you can use steps 11 and 12 in @techie_one 's procedure. Note that in that procedure, port 4 is used so if you are using port 1 like I did, you have to use robocfg vlan 2 ports "1t 5t".   If you haven't used putty before and using windows, it is a free download. Just google it.   To test that you have set up the script correctly, reboot the router after you have it all working and that it will reconnect.   ... View more

Further experimentation, there is no need to configure it as dual WAN. It seems the router automatically use port 1 as the WAN port. ... View more

I was able to make this work after a bit of trial and error ... hence I am not sure if all steps are relevant   Apologies, I don't have the luxury of creating step by step instruction but hopefully the links will help.   Be warned, it's  all over the internet that your router will not longer be supported after this process and also potentially  brick your router   1) Flashed the firmware using RT-AC68U merlin firmware. (https://uktechhub.com/forums/topic/rmerlin-asuswrt-merlin-firmware-and-the-asus-dsl-ac68u-pppoe/ ) . ADSL feature will be gone, don't know what else, but there are a lot of Merlin features that I'd rather have.   DSL-AC68U will look like the below after successful flash     2) Set-up router to use Dual LAN  - I've set-up Port 1 as primary - WAN - secondary - Set-up in fail-over mode   3) Populate WAN details (user name password) as per the TPG supplied router. For some reasons, my password is not my account password but I copied what was in the TPG supplied router   4) The "not so" tricky part is to configure VLAN 2. I used a script for this - https://github.com/RMerl/asuswrt-merlin.ng/wiki/User-scripts - https://superuser.com/questions/1384906/how-do-i-persist-vlan-settings-on-my-asus-rt-ac68-router - use the services-start script, add the following code #!/bin/sh touch /tmp/000vlanconfigured robocfg vlan 2 ports "1t 5t" 5) In the router UI, goto LAN->IPTV and set - Select ISP Profile -> Manual Setting - Internet VID=2, PRIO=0   6) The bits that I don't understand (further experimentation needed, time permitting). - Since I have configured it to use Dual WAN, I was expecting that port 1 will connect to the internet (I plugged  my uplink to port 1). However, in the router, port 1  will not connect, then after x retries it will fail-over to the WAN, and then the WAN  will connect.   Hope I have not missed anything :)   ... View more
