Subject: bizarre network problem on kernel 6.6.4

Message-ID: <39e47336-79f6-5465-7768-a405e2ee3b0a@ik.me> (raw)
Hello,
I have the most bizarre network problem on my laptop that I have ever
seen, and I don't even know where to start:
This is lenovo T14s Gen 4, using qualcomm driver ath11k_pci
Previously I was using kernel 6.6.1 and wireless network was working fine.
Now I compiled kernel 6.6.4 with identical config, and when I boot it,
wireless network does not work:
- WPA supplicant authenticated and associated successfully
- ifconfig shows interface wlan0 is configured properly and has IP
address 10.1.4.8
- route is configured properly:
default via 10.1.4.1 wlan0 onlink
10.1.4.0/24 wlan0 proto kernel src 10.1.4.8
but I cannot ping even my Gataway: 10.1.4.1
bizarrely, when I start tcpdump on my gateway, I see arp requests coming
from my laptop asking for some strange public ips, such as 208.163.36.0
when I interrupt ping, and start again, then arp asks for other strange IPs.
But in every case, I see only these arp requests, not the pings coming
from my laptop.
But when I ping the other way (from gateway to my laptop), I do see the
incoming pings on my laptop (but no response pings)
Also, with "arp-scan -l" on my laptop, I see other devices on my
wireless subnet:
10.1.4.1 00:0d:b9:53:ea:3c PC Engines GmbH
10.1.4.2 b0:7f:b9:50:5b:21 NETGEAR
any idea what is going on?
