I was being stupid and messed with my ip address.so I can't connect to the Internet now but it says status connected and I can connect from my iPod(that I'm on). I tried going to cmd prompt and going to ipconfig /all got my ip address and typed it in along with the subnet mask but when I go to set my ip address it comes up with an error saying the" ip address you have entered for this network adapter is already assigned to another adapted on this computer." Also ipconfig /release and renew come up with an error message saying "operation failed as no adapter is in the state permissible for this operation" What do I do??

You can configure the ip address manually. E.g.: Assuming your routers ip address 192.168.0.1. Assuming the ip address you're trying and fails is 192.168.0.50. Go into the network cards configuration / tcp/ip and set the ip address manually: ip: 192.168.0.51 network mask: 255.255.255.0 dns: 192.168.0.1 (your routers ip address) You may have to change routers ip address for your needs. Please send a reply, if you solved the problem !!!

Sounds more like you played with the nics hardware properties. Seems that nic still exists according to the message. And that message would indicate a static ip assignment which also explains the error when you tried /release. There was nothing for dhcp server to renew with this nic. Are you sure you weren't originally set to "obtain ip address automatically"? Then you would get an ip from a dhcp server. Like you would if you were connecting to a home router.

I am connecting to a home router and I messed with the stuff in my network properties my tcp/ip so idk it's all confussing me

In normal cases, when router is configured correctly, you don't have to configure your computers with static ip addresses. All informations, that are needed to connect to the router and the internet comes automatically from the router. So if there is more that one network card installed to your computer, you have to check the settings of all the network cards. I suggest to set all network cards to optain ip address and DNS server automatically. Then restart your computer an pray :-) Please send a reply, if you solved the problem !!!
