I’m trying to diagnose a network issue where some of my computers are configuring themselves correctly on start up but fail to configure correctly on wake up.
On start up they grab the default gateway of 192.168.0.4(firewall) but on wake up they grab 192.168.0.1(router).
I’ve tried changing the power settings to turn off fast boot up, and I’ve tried setting my routers to dhcp instead of static, I’ve also tried giving my computers static ip addresses, non of this has resolved to provide me with a stable internet connection and I’m running out of ideas.
If I set a static IP address on the client then revert it back to DHCP it configures itself correctly.
So switches are
Default gateway: 192.168.0.4
Other computers one the network are getting 192.168.0.4 as the default gateway but this computer on startup gets 192.168.0.4 and one wakeup gets 192.168.0.1 As far as I can tell this computer is the only one with this issue.
I have not but I definitly will tomorrow. I was sort of working under the assumption that it was the computer itself because all the other computers arn’t showing this flakey behaviour.
Im planning on swapping out the problem computer tomorrow and seeing if a new computer does the same thing and if it didn’t I was going to commit to the idea of it being an issue with the computer but I’ll rule out a second DHCP server first. If both those don’t show promise, then what else might it be?
This was perfect, it turns out that my firewall was intercepting DHCP requests and causing the issue, I’m just trying to get in touch with the previous IT person to figure out why this DHCP service is still enabled.
