For about a week i will be stuck with wireless internet only and my PC doesnt have a wireless adapter. However, my laptop does have a wireless adapter and can connect to the internet with it just fine, so i was looking to use my laptop as an incredibly overpriced wireless adapter for a week or so. I know it is possible but i cant seem to find any up to date guides on how to do this.

The laptop is running on windows 8 and the PC is running on windows 7, but the only guide i can find doesnt show what to do with windows 8 so any help in getting this working would be much appreciated.
 
Google internet connection sharing. Basically you need to bridge the wireless adapter and the wired connector. if you open Network and sharing centre the click on change adapter settings right click the wireless adapter and click share (it should be there I don't have a machine with a wireless card any more to check). If not select properties and then share. make sure the wired connections are both set to DHCP first as the wireless adapter will take control of how they work.
 
i finally found my way to the right window to change the sharing settings and did everything you said, but when i tried to use the internet on the PC it was complaining about IP addresses being misconfigured. Does that mean they arent set in DHCP mode?
 
I never managed to get it to work any way other than setting up manual IP addresses. It was a few years ago now too so I can't remember exactly how I did it.

Edit: I think I gave my laptop an IP of 192.168.0.1 only, left the DNS blank. Then gave my PC an IP of 192.168.0.2 and used the laptop's IP as the default gateway and DNS

The Wireless adapter needs to be on a different subnet to the wired adapter, so if your laptops wireless connection has an IP of 192.168.0.10 (for example) the wired connection needs to be 192.168.1.1 or it will end up getting confused.

You do not need to set the Gateway or DNS Windows Internet connection sharing wizard should sort all that out automatically.
 
Thank you all very much for the help, but it just flat out isnt working. i've tried everything you are saying and it still complains about either the network not being configured correctly or the DNS server not responding (which i reckon is just because of the network not being configured properly)
 
I've had to do this in the past. I'm a little rusty but I think settings go something like this:

Laptop Wireless IP Settings: Use DHCP as usual. Use IP config to check dns settings
Laptop Wired IP Settings: Use static. Set to same subnet as the other adapter but different IP address. Make sure it is outside the DHCP pool.

PC IP Settings. Give IP address and subnet the same settings as the DHCP gives out. Make the gateway the laptop's Wired IP. DNS needs to match the Laptop Wireless DNS settings.

Example Settings. Try to match these:

Wireless Example through DHCP:
IP: 192.168.1.64
Subnet: 255.255.255.0
Gateway: 192.168.1.1
DNS: 192.168.1.1

Wired Static:
IP: 192.168.1.2
Subnet: 255.255.255.0
Gateway: <Not set>
DNS: (Obtain auto, basically not set)

PC Settings:
IP: 192.168.1.5
Subnet: 255.255.255.0
Gateway: 192.168.1.2
DNS: 192.168.1.1

I hope this is right as it's a long time ago since I last had to do this. Basically you need to route through the wired connection on the laptop to the wireless, meaning IT DOES NOT HAVE TO BE ON A DIFFERENT SUBNET.

I'm slightly unsure about the laptop wired settings. I think that's right above but you MAY need to set the gateway to the same as the wireless adapter, in this instance: 192.168.1.1 and if it still doesn't work, maybe the DNS as well.

Thank you very much for that, i might give it a try later. unfortunately the only wireless signal i can pick up in my room cant connect to the DNS server now, so its pretty much useless for web browsing
 
I may have been making a bit of a boo-boo when i was trying the 'shared' option. is it the wireless adapter that needs to be shared, or is it the wired connection that needs to be shared? originally i was trying to share the wireless because i figured it was what both computers were using, but i realised it is the wired connection that the PC will be using so it might be that one that i have to share. can anyone confirm which i need to do (or is it a bridge that i need)

ps. My dad said that to make a network bridge i need a crossover cable rather than a standard ethernet cable, is that right or did i just explain things badly to him?
 
Your dad is old. All modern tech PCs / Laptops will autosense regardless of the cables.

Be careful here as in some of the above replies there has been mention of bridging the adapters and looking for ICS. They are not the same thing.

IE, if I want my XBOX to have a wired connection (because it's old and doesn't have WiFi) I enable both adapters on my laptop, then highlight them both (CTRL Click each adapter), right click and choose "bridge". That's it, the Xbox will have a connection (assuming you have plugged a LAN cable in from the laptops ethernet to the back of the XBOX). Xbox in my scenario, PC in yours. Set the PC to be DHCP automatically.

ICS is different, subtle, but still different.
 
Then I don't know what to tell you kid. It does here. I had to do this repeatedly for a while when I had no physical connection for the xbox. Wireless connected to router, click both adapters, bridge, turn on xbox, play games....(laptop set to DHCP too)
 
Using the method I typed you don't actually have to set it to share, this is if you use a single cable going in and out, i.e. I used my Dad's computer to share our broadband connection a long time ago (before we got our first router) and all I had to use for that was ICS.

However as a correction, try:

Wireless Example through DHCP:
IP: 192.168.1.64
Subnet: 255.255.255.0
Gateway: 192.168.1.1
DNS: 192.168.1.1

Wired Static:
IP: 192.168.1.2
Subnet: 255.255.255.0
Gateway: 192.168.1.1
DNS: (Obtain auto, basically not set)

PC Settings:
IP: 192.168.1.5
Subnet: 255.255.255.0
Gateway: 192.168.1.2
DNS: 192.168.1.1

Don't know what else to suggest really.
