Re: Some devices randomly losing their IPv4 address

So if your router gets the response in first, the the client gets a message about no free addresses. If your dhcp server system wins, then the client gets the IP address. I can't see an easy to way to solve this other than the workaround you tried.

That was my first thought.

A couple of other workarounds did come to mind :

1) If the OP can find a suitable switch with the right speed interfaces and which also has DHCP filtering (a.k.a. rogue DHCP server protection) then that could filter the ISPs router responses.

2) Rather than trying to build a single router that does 1.<whatever> gig - would it work to segregate the network (it’s was suggested that this was wanted anyway) so that a number of 1G capable routers connected the different segments ?
