Use Raspberry PI as Wifi adapter for PC

[mdrabble]

I have a temporarily have a PC at home which is nowhere near the router and no Wifi adpter for this PC.

 

Don't intend to purchase a WIFI adapter for PC as I'm only using the PC whilst working from home etc and then it will be going back to work.

 

I have a Pi3 - and I was wondering could I setup the PI in such a way that I could connect the Pi and PC together via an Ethernet cable and enable to PC to use the Wifi connection on the PI so the PC has network access?

 

Hope that all makes sense...... busy multi-tasking and it isnt one of my strong points!!!

 

Cheers

The word you want is Bridge, although there seem to be a lot of variants with the Pi acting more like a router.

Is the pi using a built in wireless nic? Otherwise take it out of the pi?

It's a single board device, you can't.

Yep that is exactly what I’m after.

Well it works - but as the PI 3 is a n adapter it slow and I’m luck to get 4mb speeds - so decided to order an cheap ac adapter from amazon.

 

Might look at this more in the future with a PI 4 as then has an ac adapter and will enable me to network some kit where I cannot run cat 6 cables.

Raspberry Pi ethernet isn't fast as it runs over usb.

 

Just install ethernet cables everywhere, worth it in the long run

I don’t think that’s the case with the Pi 4.

You're right, "Using the PCI Express bus provided by the new BCM2711 means that not only do we now have USB 3.0 capability, but the Gigabit Ethernet than was previous provided via the USB bus and the LAN7515 chip—which had a maximum throughput limited to around 300Mbps—is now provided using the Broadcom BCM54213PE on a separate bus to the USB traffic."

In which case run a) iperf to check network speeds, and b) htop to monitor cpu usage

I have a PI 4 8GB and I will say that even the most basic one would be in my opinion a waste of the hardware! you can get cheap (and ok nasty) wi fi adapters for less than the cost of the most basic PI and you do not have to home brew / spend life fixing a home brew to do what you want (this coming from a guy schooled in the art of Heath Robinson!).

I’ve ordered a WiFi adapter for desktop which solved drive immediate issues.

 

Was thinking of PI as a bridge to network upstairs office as it isn’t practical to run cables from downstairs.

 

Could move my qnap Plex server from downstairs as wife is always complaining about it - upstairs would be out of sight and out of mind :-)

"why are there wires everywhere, can't you just watch what's on normal tv?"?

 

I found a painted over cable trunk in my house today, now to replace the 7 cables for the security system with something useful like ethernet

You could probably get a Pi 4, 8GB to act as both a network bridge and Plex server if you wanted - add a USB 3 harddrive and you should have a decent amount of storage. More of a project to learn as you go along rather than the simplest solution available, but might redude the number / size of devices you have floating around the place.
