Hey guys. I just moved my desktop upstairs and its to far away from the router to run a cable. I've been using internet connection sharing on my laptop to work as a makeshift wifi adapter but it seems to be acting strangely.
I had already had internet connection sharing enabled on my laptop because I use it to connect my xbox 360 to the network instead of paying 100 dollars for a usb adapter.
Here's what I find strange. My computer is running a fresh install of windows 7. I connect the ethernet cable between my windows 7 box and my laptop running windows xp. It works flawlessly and my win7 box is configured using DHCP.
Later I walk away and take my laptop downstairs w/out powering either machine off. I just unplug the network cable and go downstairs for about an hour. When I come back up the win7 box can't connect to the internet. I ran through the lil diagnostic program and it said the computer couldn't reach the DNS server.
I had to manually go in and edit the IPv4 settings and set a static IP and tell it were to find the DNS server. I had to do something similar w/ my xbox. But in the end I got it working.
I made up and IP address along the lines of 192.168.0.xx
Set the subnet mask to 255.255.255.0
Set the default gateway to the static IP asigned to my ethernet port on my laptop.
Lastly I set my DNS server to the address of my router/modem.
Everything works perfectly but it bothers me that I have to go through this when obviously DHCP should function. Does anyone know why DHCP would randomly stop working like this? I never have this problem when I fire up ubuntu on my PC. Is it a Microsoft networking thing? (hence the reason I have to use the same procedure on my xbox.)
