    Cake settings for only upload speed

    Setting the CAKE bandwidth to 0Mbit/s for download will effectively disable it for download. Setting 5Mbit/s for upload will handle your upload-related bufferbloat, but your download-related bufferbloat will not be addressed. To deal with your varying download link capacity, you would need to...

    FlexQoS FlexQoS 1.3.2 - Flexible QoS Enhancement Script for Adaptive QoS

    Ah, I see. Given all the complaints about CAKE topping out circa 400-500 Mbit/s on OpenWrt, I am curious - can FlexQoS go higher? @timko so then for your case perhaps CAKE on wan is worthwhile considering. If you don't use a VPN, then I believe you don't need to do anything other than switch it...

    FlexQoS FlexQoS 1.3.2 - Flexible QoS Enhancement Script for Adaptive QoS

    @dave14305 what prevents this? Does/can FlexQoS work with ifb's so all the set parameters relate to the chosen interface, be it br0, br1 or a custom hybrid ifb?

    WAN was exceptionally disconnected

    If these issues are related to the same problem I had, namely absence of timely udhcpc release/renew on NO-CARRIER events, then this script may fix the problem: https://github.com/lynxthecat/maintain-wan-lease

    Problem: udhcpc does not deconfig upon WAN cable disconnect

    If you have a spare sim you could hot swap it on the B818-263. I think this might force the same event. Otherwise for me it happened exactly every 48 hours. I would deactivate script and test personally. You only want the script if it is needed. Then again, if you are pushed for time and don't...

    Problem: udhcpc does not deconfig upon WAN cable disconnect

    Have you tested post reboot by manually unplugging cable and plugging in again? And checking syslog to see the entries? By the way, it is these lines in the B818-263 log that result in 'eth0' going down and back up (at which point we need the release/renew to get new WAN IP): 2022-03-02...

    Problem: udhcpc does not deconfig upon WAN cable disconnect

    Thanks @dave14305 I amended the readme. https://github.com/lynxthecat/maintain-wan-lease The scripts I had saved from my Asus Router that were auto generated by ATM (IIRC) seem to include a mixture of sh / bash shebangs. Should all the scripts use: #!/bin/sh I will amend that too. Done...

    Problem: udhcpc does not deconfig upon WAN cable disconnect

    Update: uploaded script onto my GitHub for resolving this issue. Confirmed to work by myself and at least @optimalo: https://github.com/lynxthecat/maintain-wan-lease/blob/main/README.md

    RT-AX88U "ISP's DHCP does not function properly" but manual udhcpc call works

    Glad to hear it. Another user just messaged me to confirm the same. Here is the script on GitHub: https://github.com/lynxthecat/maintain-wan-lease/blob/main/README.md Yes I agree, Asus should implement something along these lines because the default behaviour is broken. Please keep me posted...

    New to networking - does my router support CAKE?

    Thanks for the mention and link to my GitHub repository. The shell script in my main branch is nice and simple and generally works. I imagine it could be made to work in Merlin without much trouble? With some guidance from @moeller0 of OpenWrt (also one of the CAKE contributors, and in any case...

    Asuswrt-Merlin and Nordvpn

    Was this with the RT-AX86u? If so, I'd have expected that number to be a bit higher given WireGuard performance on devices with weaker processors on OpenWrt giving around 300 Mbit/s. Is there something like irqbalance to improve performance? On OpenWrt this gives a huge performance boost for...

    Asuswrt-Merlin and Nordvpn

    What rates do you gents see with NordVPN? I only have LTE so can't test it.

    Mysterious loss of connectivity

    @RMerlin I wonder if the following 'maintain-wan-lease' script should be included and enabled by default in your releases to overcome problem that disconnect does not trigger release / renew: #!/bin/bash renew_wan_lease=0 ip monitor link dev eth0 | while read event; do logger...

    Need to replace my AC68-U - what router is recommended for Merlin's excellent firmware these days?

    I think the RT-AX86u would be best for you. I found the 5Ghz on the RT-AX86U to be extremely fast and reliable. I saw speeds of around 60Mbytes/s between client and router. I think the hardware is nice but it annoys me that udhcpc kill commands are not sent on wan disconnect. So that resulted...

    Simplest QoS option

    Looks really nice to me. I wish I had such a connection. Instead I have an LTE connection that swings between 30 and 70 Mbit/s. That, and VPN, makes getting CAKE to work well rather a challenge. Fortunately with custom scripts dynamic bandwidth / VPN is manageable.

    Simplest QoS option

    +1 for CAKE And please post test results: https://www.waveform.com/tools/bufferbloat

    Router not getting internet back after WAN drop

    @RMerlin appropriate udhcpc kill commands need to be sent on eth0 down but they are not at present. Issue can be easily reproduced. Unplug cable and see!

    Separate out WAN/LAN <> router ingress/egress on br0

    I wrote a script to apply CAKE in the context of VPN PBR in OpenWrt. CAKE can consume identifiers enabling WireGuard upload flows to be differentiated following encryption. For download an IFB is created and the flows from the wan and WireGuard interfaces combined there...

    Separate out WAN/LAN <> router ingress/egress on br0

    Thanks. You initially put me on the right track for my Merlin RT-AX86u router with your 'br0'/'tun11' suggestion, for which I am very grateful. During my experimentation with OpenWrt I made further progress with the help of some of the experts there, but unfortunately still never managed to...

    Separate out WAN/LAN <> router ingress/egress on br0

    How would I go about separating LAN <> router ingress/egress and WAN (VPN/bypassed) <> router ingress/egress (all presently on br0)? I believe that one way is to create a veth pair - device veth0 and peer veth1, then add veth1 to br0, and then shift inbound WAN or tunX traffic to veth0 using ip...
