Raspberry Pi 4B - wifi connects but does not send/receive data

[Paul W. Rankin]

Hello,

I've installed OpenBSD 6.9 on my Raspberry Pi 4B and can connect to wifi
networks, but I cannot send/receive any data.

I installed by dd'ing install69.img to SD card, booting from SD card and
installing the root system onto a USB stick. I copied over
bwfm-firmware-20200316.1.2p2.tgz on separate USB and installed the
firmware with fw_update.

The RPi4 now boots fine into multi-user OpenBSD. I can connect to a wifi
network and obtain a DHCP lease. I can see via the router web UI (using
another machine) that the RPi4 is connected with an IP address. However
I cannot sent/receive data, e.g.

$ pkg_add -u
# long wait... nothing...
^Cpkg_add: Caught SIGINT

$ ping example.com
# long wait... nothing...
^C
$ ping 192.168.8.1 # <- router IP
PING 192.168.8.1 (192.168.8.1): 56 data bytes
# long wait... again nothing
^C
--- 192.168.8.1 ping statistics ---
21 packets transmitted, 0 packegs received, 100.0% packet loss


I don't think it's an issue with the router because I've also tried
setting up an ad-hoc network between my Mac and the RPi4. I can join
this network, but attempting to ssh ***@xxx.xxx.xxx.xxx results in the
same apparent lack of sending/receiving any data.

I don't think it is faulty hardware because I've also tried the above
with a urtwn-compatible USB wifi dongle (having installed the firmware)
with the same results. Also the hardware had previously worked with wifi
on an Alpine Linux installation.

Any suggestions of how to troubleshoot this would be very much
appreciated.

Thank you for your help.
