HI, I have three laptops connected directly to an Infinitum ADSL modem, Model HG530, using DHCP. One laptop is connected wirelessly. The other two use Ethernet cables. I also have an external hard drive connected to the modem.
One laptop is just there to run my magic jack. Up to a week ago, that was my good laptop. I had no problems with it ever.
Twice in the last week I've noticed an IP conflict, always on that laptop. I reboot and sometimes it goes away, sometimes not. Today it won't connect to the internet. I've rebooted the laptop, rebooted the modem, and replaced the Ethernet cable. It comes up for a while, then goes out again. I moved the Magicjack over to my good laptop and it's working.
An ipconfig on the laptop that can't connect, which we can call the Acer, shows:
IP address: 192.168.1.102
Subnet Mask: 255.255.255.0
Default gateway: 192.168.1.254
The modem shows a connection light on that laptop's input.
Thanks! I can also get access to the control panel of the modem if you need information from there.
