Android phones cannot obtain IP address

I recently updated to 21.02 on my Linksys WRT3200ACM ... after some stability fighting it now appears as stable as 19.07 for my use-case. There is however one problem. I cant get any of my Android phones to obtain an IP address. I've tried with a Pixel 5 & Samsung Galaxy 10. They connect, but after connection IP negotiation fails.
I don't have this problem on my very cheap Android-based smart tv or my laptop (linux). Both 2.4 & 5 GHz works fine.
Updating to 21.02.1 did not solve the problem.

Does the problem occur only in IPv4 or IPv6 as well?
Let's have a look at the configs:

Here is what the log generates when Android phones try to connect :

The only visible issue is that OpenWrt doesn't offer any IPv6 due to lack of public prefix.
It would be better to disable the RAs and DHCPv6 if you don't have any IPv6.
Other than that it would provide more insight to capture some packets when the android phones connect
opkg update; opkg install tcpdump; tcpdump -i br-lan -evn ether host xx:xx:xx:xx:xx:xx and use the mac of the phone.

I have upstream IPv4 & 6 .. But I think its a problem with IPv6 and OpenWRT 21.02, based on the log I have - how do I disable it, the internets is full of complicated suggestions ?.

Post along with the tcpdump also this one: ifstatus wan6; ifstatus lan

tcpdump: listening on br-lan, link-type EN10MB (Ethernet), capture size 262144 bytes

You run tcpdump with wrong arguments -xvn instead of -evn and you've run twice ifstatus lan

I ran with -evn .. just copy and pasted the command from your post.
Updated ifstatus lan6

That looks more like -xevn with the HEX and ASCII. And there isn't anything useful there anyway. Did you try connect the phone while tcpdump was running?

Anyway, regarding IPv6, you get the prefix but you have configured not to use it:

Tried turning it on .. no change. Guess I'll revert to 19.07 .... maybe try pfSense in the long run, using my Linksys as a plain AP :smiley:

Thx for trying to help.

UPDATE : Back on 19.07 ... Android phone connects instantly and with zero issues.
