Can I use my raspberry pi to give my computer WiFi?

[Guest]

My new computer doesn't have wifi but it does have LAN, but I don't want to have an ethernet cable across my room. But I have a spare raspberry pi 3 with wifi, is there a way to connect these two to have wireless internet access?

Yes there is, you need to set up a DCHP server on your Pi. This will let you share the Pi's WiFi via Ethernet.

 

I found a couple tutorials for this, but haven't been able to really get into it as much as I'd like:

This guide is for Xbox 360, but all the technical stuff is done on the Pi. It still works the same way as if your intended sharing device was a PC.

Easiest and most reliable thing to do would be buy a wifi adapter. You can get PCIexpress cards or USB adapters. They're cheap and start at about $10 USD, though I'd recommend one of the ~$20 PCIe cards over the cheaper USB wifi dongles.

I have one in the mail right now but it’s going to take several weeks, so I don’t want to wait that long.

You could try and route the traffic through an ssh tunnel

ssh -D [PROXY_PORT] -f -C -q -N [USER]@[RASPBERRYPI]

and then set up your system / browser to use that as a proxy (localhost:[PROXY_PORT]). It might work and only takes a minute to try.
