So network was running fine for about a year or so. Network consists of 1 Motorola SB6120 cable modem attached to a D-Link DIR-601 wireless router. All settings were default except for SSID and WPA password. One day I just couldn't access internet anymore. I've narrowed it down to the default gateway that is being given out through DHCP. The default gateway that is being given out is the IP of the modem (192.168.100.1) and not of the Router (192.168.0.1). I can't find any option on Wireless router to be able to force the gateway address when handing out the gateway IP. Theoretically I thought I should be able to put router on same subnet as modem as 192.168.100.2 but that still doesn't work. If I set the IP adresses statically on the PCs and give it the Gateway of the Router everything works fine. I should mention this is for my boss' house and basically I dont want him calling me everytime he has a friend come over and I have to talk em through setting up a Static IP.
And just for an example this is what I get if I use DHCP:
IP Address: 192.168.0.155
Mask: 255.255.255.0
DNS: 192.168.0.1
Default Gateway: 192.168.100.1
And If I want it to work I have to change the default gateway to 192.168.0.1
I've tried updating routers firmware and reset to factory default numerous times. Is it possible for a router DHCP stop working? I've never heard of that. ISP is Comcast and when I talk to them all they can suggest is unplugging everything.......like 500 times.
