Can Desktop Use Wifi via a Laptop?

PKLee
 Share

This sounds totally unnecessary and rediculous, but here's my situation.

 

I'm about to move into a new apartment, that's what I've been looking for in the past months, except that my network would not be ready until 1 month after I move in. I talked to my new neighbours, they're nice and said that I could use their Wifi for the first month. My laptop and phone have Wifi, but my Desktop doesn't. So instead of having to buy a USB based Wifi stick or a PCIe WLAN card and getting rid of them after one month, I wonder if it is possible to simply hook up a wire between laptop and desktop, connect to Wifi on the laptop so that the desktop would be connected as well. You konw, just like Wifi hotspot on a laptop, but all the way around.

I know routers could do it, but my router comes with the internet, so that's a no.

 

Many thanks

If you already have the LAN cable, might as well try it out and see if it works or not.

I've used a phone to connect the wifi then share the connection with my desktop through usb before. But I don't remember exactly how I did it, I have a iphone and I had to use a jailbreak tether app cause the stock iphone tether doesn't support tethering wifi -> usb.

 

A good search term is "Repeat wifi signal with desktop/phone"

 

A $10 USB Wifi dongle will be something that's nice to have around though even after your done with it

Connect your laptop to wifi, select both your Wifi and LAN adapter in "Network Adapters" right click, "Bridge adapters". Connect ethernet cable from laptop to desktop.

Or you can remove your laptop's wireless card, buy a cheap mini PCIe to PCI Express card and put it in your desktop. But that's a waste of time and effort.

Okay thanks for that, but I'd rather pay for another router than jailbreak my phone...

Thanks for that, I just wonder if I had a solution where I don't have to buy another stuff... buying shitty stuff then getting rid of it is just not my thing.

I don't remember it being this easy... I think you need a special protocal in order to connect two computers without using router... or at least in the old days

I haven't done it in probably 4-5 years, but I remember this being pretty much what I did. Your NIC should auto detect that it needs to be crossed over.

How can you make two points in one sentence? Yes I could and yes I would be wasting my time

I'm just suggesting a way to solve your problem.  But I don't think that it would be the most practical solution.

Yes, What you can do is Connect to your WiFi on the laptop, Connect an Ethernet Cable from your laptop to your PC and within Control Panel\Network and Internet\Network Connections You can select both the WiFi and LAN Network Interface Controller. And select Bridge.

 

One thing that you might find is your Desktop's NIC might not support a straight through connection between two computers, and you will then have to use a Crossover Ethernet cable, or a switch in between the laptop and Desktop.

 

Another thing that you might want to consider is, the laptop will have to be on, If you mean for this to be a permanent solution, then you might aswell just buy a USB dongle or a WiFi Card. You can get a decent AC wireless card for like £30

 

Yes that's exactlly what I had in mind when connecting two computers straight ahead, you need a crossover cable... don't know how it works now.

And no this won't be permanent. I don't mind having to have my laptop open when I'm using desktop, I don't pay for electricity anyway :P
