Hello,
Recently, we have been having problems with the DHCP server in our router. Randomly, devices started to get 169.* IP addresses. I poked around in the router, and saw that it might be because the DHCP only assigned 192.168.0.10 - 192.168.0.20. Changing the second number to 192.168.0.100 seemed to fix it for a while, but now we're having the same problem again. Any ideas?
