    WAN_Connection: ISP's DHCP did not function properly.

    Likely not related, but if anyone here is using Adaptive QoS and having WAN disconnects due to DHCP renewal failing, check out this post. I've been struggling with Adaptive QoS for weeks, and just discovered the Asus Adaptive QoS rules were blocking DHCP traffic. Major problem when my DHCP...

    how to debug an iptable problem?

    Thanks, @dave14305! To close the loop on this thread, dave14305 found the solution to my AC68U dropping WAN every 10 minutes whenever I enabled Adaptive QoS. For some reason Adaptive QoS is dropping the DHCP packets, and since my DHCP lease is only 10 minutes, it was resetting constantly. If...

    "Hiccups" every 10 minutes on Asuswrt-merlin (RT-AC1900P with AC68U firmware)

    @ttorimoto this sounds like exactly the same problem I've been having trying to get FreshJR's Adaptive QoS working on my AC68U on ATT Uverse. @dave14305 helped me find the solution, and my connection no longer drops every 10 minutes and thanks to @FreshJR adaptive QoS is working like a champ...

    [Release] FreshJR Adaptive QOS (Improvements / Custom Rules / and Inner workings)

    You're a genius @dave14305! Couldn't sleep, so did some more digging and learned the formatting of that SRC address is correct, so it's not a corrupt DHCP request. Tried option 1 above, and ASUS and FreshJR Adaptive QoS is working! I see the May 8 03:49:15 custom_script: Running...

    [Release] FreshJR Adaptive QOS (Improvements / Custom Rules / and Inner workings)

    I'm no expert, but that's one weird MAC address in the dropped packets. 08:62:66:97:XX:XX = my AC68U f8:2c:18:4a:XX:XX = 5268ac gateway No idea where the ":08:00" comes from 192.168.1.254 is the IP address I access my gateway admin interface from, presumably DHCP server also 108.228.12.XXX =...

    Thanks for the pointer! Unfortunately, my setup is FTTN not FTTH - so the fiber goes to my neighborhood and then it's VDSL2 to my home so I just have the Pace 5268ac gateway which handles all the DSL, no ONT I can connect directly to. I could try to get my own VDSL gateway that may handle...

    [Release] FreshJR Adaptive QOS (Improvements / Custom Rules / and Inner workings)

    Ah, thanks for the tip. Here's an excerpt after reboot (full log since reboot here). QoS is disabled but QoS apps analysis is still on, and I re-upgraded to 384.17. Tweaked with space between /etc /hosts, and obfuscated my IP and work information. As far as activity, web surfing, Netflix...

    Just did, sorry for the delayed response, crazy days. Also I apologise if I offended you with the new thread. New here, and don't know the protocol (pun intended)... Looking to increase my understanding of ipables so I can contribute more than my ignorance and my gratitude to the investigation

    [Release] FreshJR Adaptive QOS (Improvements / Custom Rules / and Inner workings)

    Hmm, good question. Disabled via "FreshJRQoS -disable" (but didn't reboot due to family on the net but did do "service restart_firewall") and then started Asus Adaptive QoS, and it has the same problem - WAN dropped and reconnected after 10 minutes. So I guess that means it's not a FreshJR...

    Called Sonic, and ATT only allow their own ATT equipment on this plan. Not to say I couldn't buy an aftermarket gateway and plug it in to see what happens... Thanks to dave14305's help it appears to be related to the firewall since renewals happen when QoS is off but fail when it's on. But I...

    how to debug an iptable problem?

    I'm an iptables savage - I know just enough to know how thoroughly I could ruin my network configuration, and could use some help. I've tried to wrap my head around iptables several times over the years, and each time stagger away with a headache. I've run into a problem where my AC68U drops...

    Excellent, thanks! Working through it now. Interestingly, I'm not seeing any traffic through my attempt to open DHCP ports via my own rule. But putting in those dummy custom scripts helped. With FreshJR's QoS on, I get 10 minute resets. With it turned off, I see "custom_script: Running...

    Thanks, Dave! I'll give those a try. I rebooted after creating the additional custom scripts and opening DHCP, but still have the same problem. Cloudflare still blocking my syslog, so representative sample here - https://pastebin.com/kXqgdiZG

    [Release] FreshJR Adaptive QOS (Improvements / Custom Rules / and Inner workings)

    Thanks, I'll give that a try. Further reading makes me wonder if the AC68U firewall might be blocking the DHCP renewals requests, causing the connection reset and QoS reset. I tried iptables -I INPUT -p UDP --dport 68 --sport 67 -j ACCEPT but that didn't seem to do anything. Can anyone...

    Hmm, interesting question. There was a period where AT&T screwed up a firmware update that dropped DMZ+ users' bandwidth by ~40% and people were switching to a different modem. Presumably I could look up that modem and buy one off ebay or Amazon. I've been assuming the DHCP lease expiration...

    "Hiccups" every 10 minutes on Asuswrt-merlin (RT-AC1900P with AC68U firmware)

    I have a similar problem with my AT&T FTTN service and FreshJR adaptive QoS on my AC68U / Pace 5268 (my post) AT&T uses a 10 minute DHCP lease (argh!). For some obscure-to-me reason, the lease expiration is appearing as a loss of WAN and triggering the Adaptive QoS to restart. I'm pulling my...

    Kudos to FreshJR for creating this amazing improvement to Asus' QoS service! I struggled to get this configured correctly, and in the end, ended up reading all 212 pages of this thread to better understand how the script works, and how to configure it. Much of what I learned I absorbed through...
