Wierd Wifi on Pi400

Having a strange problem on my Pi400

after it sucsesfully authenticates on the Wifi it almost always fails to get a valid IP address & adopts a 169.254.x.x address. I am not using my routers DHCP server but have dnsmasq on another server because I hve equipment that needs additional options. The problem is considerable less if i use the guest network (which does get dhcp from the router) but even that fails to renew correctly & reverts to a 169.254.x.x address. it also fails to reconnect correctly after a reboot needit a number of disconnects

The same SD card works without issue in a Pi4B

I do suspect the Virmin Media stupid humb 3 may be playing some part as connecting to my mobile phane as a hot spot has sofar failed to exhibit these issues.

This may be the final excuse i need to ditch VM wifi but would like to know that what ever i buy will not have the same problem

Bypasses are devices that allow some people to dash from point A to 
point B very fast while other people dash from point B to point A very 
fast.  People living at point C, being a point directly in between, are 
often given to wonder what's so great about point A that so many people 
from point B are so keen to get there and what's so great about point B 
that so many people from point A are so keen to get  
_____there.  They often 
wish that people would just once and for all work out where the hell 
they wanted to be.

If you manually assign an IP addr on the Pi, how reliable is a ping to a wired device on your LAN? much packet loss?

How do you connect to wifi? Have you tried using dhcpcd-ui?

when connected pings are fine

After posting on the raspberrypi.org forum it seems I am not the only one with this problem when using a Virgin Media Superhub 3

It is being investigated by the RPF

Hmm...  Which would do a better job at driving physicists crazy?  Travel 
faster than light, or a floating-point boolean value?

Superhub: Modem mode, you know it makes sense.

indeed now i know it is not just me, it may be the final push

work arround for me at the present is to either use a usb wifi adaptor or connect a lan cable, neither are particularly troublesome
