Hi dears,
Archer C7 v4,
I decided to go back to 21.02.03. Then, I repeated exactly the same procedure:
removed odhcpdv6only and odhcp6c
installed odhcpd and disable it.
Then added all the same features:
adsl modem in bridged mode
static ip to access to the bridged modem
wireless Wan for WISP mode support
guest wifi for both bands
odhcpd is disabled to get rid of being spammed with error logs regarding ip v6
All configurations are the same as 22.03. However, in 21.02.03, I have no problem if I intentionally power off the router. After turning it on, it successfully assigns dynamic ip to all devices. As mentioned before, version 22.03 does not assign dynamic ip to the devices under the same configurations.
You don't need to disable IPv6, even when your ISP only provides IPv4. Just use the defaults and everything will work.
The ff02::1:2 is a "sollicited node" multicast address used by the IPv6 multicast system which needs link local addresses (non-routable, fe80::/10) to be set up.
WRT1900ACSv2 running OpenWrt 22.03.0-rc6 r19590. Upgraded from rc5 with retained configuration. 5Ghz set to channel 36. WPA2. I continue to have the following:
irqbalance enabled (from '0' to '1' in '/etc/config/irqbalance')
SQM QoS enabled
tx_amsdu disabled. Luci > startup > local startup (nano /etc/rc.local) the following commands:
Hi dear,
thanks for your reply.
When using default setup I was spammed in the log section with some messages like this :. err... network unreachable,
I've forgotten the exact message but searching the forum I had found a topic regarding the same error which was tagged as solved by disabling odhcpd.
let me reproduce the error just now...
Fri Aug 19 23:52:30 2022 daemon.err odhcpd[26218]: Failed to send to ff02::1%lan@br-lan (Permission denied)
I just enabled odhcpd and got the above error in the log section.
I disable IPv6 in devices configuration and all other settings. the same error happens when using default configuration.
Anyway, I am on 21.02.03 now. When I simply disable odhcpd there is no error in the logs. And, the router successfully assigns dynamic ip to all devices. However, in 22.03 rc6 if the router is rebooted under the above-mentioned conditions it does not assign dynamic ip to the devices.
Thanks,
Solved it.
The ADSL (pppoa-wan) interface was the only one not reporting an IPv6 address on the Network/Interfaces page in LUCI.
On the Advanced tab I enabled "Delegate IPv6 prefixes", changed the "IPv6 assignment length" to match the other interfaces; saved-and-applied.
(It added the line "option ip6assign '60'" to the "config interface 'wan'" part of the file /etc/config/network).
I have not had any 'loop-local' errors since.
Regards.
Seems to be working well on my BT hub5 which I'm using on my VDSL connection, not noticed any issues so far.
I've got it to boot reliably without encountering the really annoying BT hub5 boot loop issue by building it from source with most packages and modules built using the 'm' option so that they are omitted from the sysupgrade bin file and installing them using opkg after first boot. I've rebooted the 2 routers its installed on multiple times and they appeared to boot successfully every time, or at least there was no obvious sign of a delay.
@mjs could you please check whether using https://firmware-selector.openwrt.org/ with the minimal set of packages, as opposed to building the image from source, also avoids the boot loop?
Full disclosure: the installation mentioned in my earlier comment (OpenWrt 22.03.0-rc6 sixth release candidate - #50 by patrakov) was also performed using https://firmware-selector.openwrt.org/ using a customized set of packages. However, for me, the boot-loop problem clearly correlates with the physical location of the router and the power supply used. That installation still works (personally tested yesterday), and my friend doesn't complain about anything.
I tried https://firmware-selector.openwrt.org with rc5, or might have been rc4 and it bricked one of my routers (quite probably some mistake I made as I'd not used it before) and I've only just recovered it using serial as I couldn't get a ethernet connection even in recovery mode, so I'm reluctant to try it again!
If it is any help these are the packages I needed to install after flashing my build of rc6 (also includes some changes/extras I use for mesh)
And I believe this was the diff file I created from my non boot-looping .config . Annoyingly, I don't seem to have saved the full config file before subsequent builds with changes which resulted in it boot looping again, I'm guessing possibly because I included some of the previously omitted kmods, or its overall size.

Hi,
I reinstalled 22.03 rc6 on my Archer C7 V4. This time I leaved all IPv6 options untouched. Even WAN6 is unused and untouched. Then I reconfigured all previous features. It is running about an hour. I intentionally powered off the router two times and rebooted it several times because of installing packages. Now, it is able to assign dynamic IPs. However, reading the log file resulted as following:

there is an error reported in the last line from odhcpd. The router is now in WISP mode and is connected to another host router with disabled IPv6. the host router is using a bridged ADSL2 modem.
Installed rc6 on Mikrotik HEXs.
Updating software list in luci fails with " Check your network settings and connectivity."
Using opkg update : same problem.
But in ssh I can ping both ip as well as dns addresses successfully (also diagnostics works fine), so the basics are ok. There must be problem with the software repo ?
tailscale doesn't work since version 22.3.0. Is it necessary to install iptables-mod-chaos to run, is this a good practice? won't it break the firewall?
