My modem/router (it acts as both) has an IP of 192.168.0.1
. The subnet mask is 255.255.255.0
. The range of IP addresses used for DHCP is 192.168.0.100
to 192.168.0.200
. To be clear, if I connect with DHCP, I can connect with no issue.
I'm attempting to set up static IPs for some of my machines, and I'm running into a strange issue. If I set a static IP outside of the range used by DHCP (such as 192.168.0.66/24
with gateway 192.168.0.1
), I can't connect. From my Windows 8 PC, it shows up as "limited", and I can't connect to anything (or even ping the router).
If, however, I set a static IP that's inside the range used by DHCP (such as 192.168.0.166/24
with gateway 192.168.0.1
), it will connect with no problems. The subnet mask is not wrong.
This happens whether I use Wi-Fi or Ethernet, and I've looked around in the web interface for my router, and tried temporarily disabling the firewall (no change), and I've power cycled the router and even reset it to factory defaults (again, no change). It is not limited to my Windows PC; every device I have that I can set a static IP on shows the same behavior.
I couldn't find any other settings in the web interface that seemed relevant, and I've never had a situation like this (but, I'll admit I'm kind of a noob when it comes to networking), and I'm out of ideas. For now, I just set the IP to the upper end of the range, and I'm looking into switching out the modem/router, but does anyone have any idea what the problem could be?
