Problem installing FlexQoS on Asus RT-68U

[swizzleD]

Greetings!

I'm getting an error when installing FlexQoS an Asus RT-68U wireless router running firmware version 3.0.0.4.386_51722 and could use some assistance. I have three of these devices running AiMesh. Here's what's happening.

1. Executing the following command successfully places flexqos.sh in /jffs/addons/flexqos directory, (confirmed)

/usr/sbin/curl "https://raw.githubusercontent.com/dave14305/FlexQoS/master/flexqos.sh" -o /jffs/addons/flexqos/flexqos.sh --create-dirs

2. Executing...

chmod +x /jffs/addons/flexqos/flexqos.sh

presumably sets flexqos.sh to executable.

3. This is where the process fails. Executing...

sh /jffs/addons/flexqos/flexqos.sh -install

returns the following error: line 23: can't open '/usr/sbin/helper.sh' I can confirm that helper.sh does not exist.

I've located helper.sh at https://raw.githubusercontent.com/RMerl/asuswrt-merlin.ng/master/release/src/router/others/helper.sh. Can someone confirm that this is the right file? If not, could you point me to the correct one?

Presuming that I get past this hurdle, there's one other matter. Since I'm running AiMesh do I need to install FlexQoS on each router individually or is FlexQoS propagated from the gateway device?

Many thanks!

You’re running stock firmware. It’s only supported on Merlin firmware.

After you fix the firmware issue - AiMesh nodes are Access Points (wired) or Repeaters (wireless). No routing there. QoS is a Router feature.

Thanks for the speedy response @dave1405 and @Tech9. I really appreciate it!

I was under the impression -- wrongly, as it turns out -- that FlexQoS would remove or minimize the problems of dropping/delaying of active VoIP sessions during AP handoffs within the AiMesh. Since that's not the case, can you recommend any other remedies for that problem?

…can you recommend any other remedies for that problem?

Sorry, no. I am not familiar with that problem since I don’t use AiMesh.

My only suggestion is to stay in one place while you’re on the phone.

This issue is unrelated. QoS options you see in GUI are on the WAN side, not on your LAN side. For better roaming you need better Wi-Fi equipment with 802.11k/v/r support and compatible clients. Your router is 12 years old model and End-of-Life. Wireless uplink (or what Asus calls Backhaul) mesh system is making it worse. Band Steering (or what Asus calls Smart Connect*) is making it worse. Seamless transition is only in advertisements. You have some chance with Cisco/Aruba cluster of APs or lower priced Ubiquiti/Omada with both BSS Transition and Fast Roaming enabled and to modern Wi-Fi 6/7 clients only. You still can't get faster than 2 seconds transition and it may break VoIP, so not guaranteed.
