Well hopefully he read the instructions from Asus that are clearly stated in the support section and tried the complete process before he did that :-)

Assuming @booji got his problem sorted out as there has been no response from him.

What does the router show as after a power down, power on reboot? A DSL-AC68U or an RT-AC68U?

I have some time tomorrow to look at this, I have a DSL-AC68U that I deliberately changed into an RT-AC68U. I will try to push it back to being a DSL-AC68U.

Just to check a few things first.

1. You are using the restoration version of the firmware with the restoration tool.
2. You have followed the advice on the Asus website which says that once you have recovered you should immediately update again using the normal (not recovery) version of the firmware. No resets in between.

Please confirm you have done this and then I’ll take a further look at it.

Just making sure, I rather stupidly tried to plug an ethernet cable into the DSL port a few days ago, took a few seconds to click.

The DSL I converted to RT is part of an AiMesh filling in a blank spot for some fussy kit, so far it seems to do a pretty good job. When I was testing it out after working out how to convert it, I was using it to connect a few streaming devices by ethernet and it again did a pretty good job.

What I can’t believe is that TP-Link blatantly copy Netgear’s switch kit to the point that they don’t even bother to change the model number by much see GS vs SG series.

Hate to disappoint you but the DSL socket on a DSL-AC68U is an RJ11 not an RJ45 so an ethernet cable won’t fit.

If you’ve run out of LAN ports on the router just use a gigabit switch https://www.amazon.co.uk/TP-LINK-TL-SG1005D-5-Ports-Gigabit-Ethernet/dp/B00ZOOJXEG/ref=sr_1_1/259-2947446-7044839?s=computers&ie=UTF8&qid=1549544771&sr=1-1&refinements=p_4%3ATP-LINK

You’ll lose one port with the connection between the router and the switch but gain 4 or 7 more.

BTW not an endorsement of TP-Link kit, but it’s cheap and works.

This is interesting. If I converted my DSL-AC68U into a RT-AC68U following this method and then wanted to change back , I presume it would just be matter of repeating steps 1 and 2 with the latest DSL firmware from asus.com, without changing any of the nvram settings @six mentions?

I haven’t tried going back yet, I had a job for the RT-AC68U AiMesh node to do and it’s currently still doing it. I will be getting hold of another (real) RT-AC68U soon so will be able to experiment again if you want definitive proof of reversibility steps before trying it.

My prediction is the recovery flashing of DSL firmware will do the job on it’s own but at the very most I expect the only other thing you would need to do is the nvram set asuscfeodmpid=”DSL-AC68U” & nvram set asuscfecommit=1 commands via telnet.

No need to start down the somewhat risky road of hacking the CFE Bootloader.

There is a typo* in the instructions I shared.

nvram set asuscfeodmpid=”RT-AC68U”

nvram set asuscfecommit=1

Will do the trick and will survive the reboot.

* Sadly the router will accept any old nonsense that you decide to set, so you went through the right steps to check the settings but sadly the cpe part created a variable that is completely meaningless to the router. Use the corrected commands and it will work.

Hi Mharv

The Draytek 130 had the latest BT firmware and was correctly set up in Bridge Mode.

IPTV settings were also correct (note that GT-AX11000 does not have an option for IGMP Snooping on wired LAN).

I’ve a long history with Asus routers, most of the suggested settings you will see posted on forums today come the results that I and a few others arrived at after some experimentation years ago.

The DSL-AC68U had issues with handling BT 4K if any of it’s extra features were switched on (Ai Protection etc.) The CPU would get overloaded resulting in the WiFi slowing down to a crawl, particularly on 5GHz. Switching everything apart from the Firewall and DDoS Protection off helped.

In this case the CPU is much more capable, the CPU is not maxing out and the WiFi is not grinding to a halt. What appeared to be happening was that the Multicast transmission was swamping the BT IPTV box, leading to very bad breakup of picture and sound. That Multicast traffic appeared to be doubled when using the Draytek (according to the Traffic Monitor on the router). Using the HG612 the traffic appears to be halved and the problem goes away.

Note this only causes an issue with the BT Sport 4K UHD channel 433, all the other IPTV channels (the HD ones) will work without issues with the Draytek in Bridge Mode.

You are right that this is all very weird.

Have solved the issue after a lot of work and swapping of kit and cables.

An extremely frustrating process full of false hope as the 4K picture settles then degrades again.

Tried every setting under the sun on the router.

Jumped technology with the Powerline setup from 1200Mbps AV2 to 2400Mbps G.hn.

Tried various new Cat 6 and 7 cables to rule out local interference.

Double and triple checked the Draytek settings although tbh there was nothing to change once in bridge mode. Yes it was running latest BT firmware.

Then as a last gasp I swapped out the Draytek for a BT HG612 and hey presto, rock solid picture.

Looking at the traffic monitor somehow the multicast traffic was doubling and also spiking even higher when using the Draytek.

Not sure I have a long enough cable but will have a dig around and see if I’ve got anything suitable lying around.

If there is anything else that Asus need from me please let me know.

OK so fully disabled AiP and rebooted. Sadly no difference.

Tried just about every combination of settings I could think of, still no difference.

Find it really odd that the Traffic Analyser doesn’t show the incoming traffic but the wired LAN shows the outgoing traffic.

If you can get Asus to shed some light on this I will be very grateful.

This is a very new router so I guess it’s entirely possible that it’s one of a number of bugs that will be ironed out in the coming months.

Finally done it. Need to work through the steps before I can share.

AiMesh set up and running nicely.

Yes I caught the dms_friendly_name change, just didn’t change it in the posts yet.

nvram+commit?

OK this is not working at present, trying to find out why the nvram set commands won’t survive the AiMesh enabling reboot.

Yes on 5252.

Nothing else has changed.

Powerline adaptors are TP Link 1200, they work fine.

4K was working fine if AiProtect was turned off on 68.
