A direct line to your computer from ADSL? That's not as easy as you think it is.

You would need a ADSL modem card in your computer and also configure static IP addresses and static routing on the machine to use the Internet at all. And to do that all of that you need quite some information from your ISP for the DSL modem configuration that they probably won't give to you so easily. Oh, you would also need to actually configure the Windows firewall properly because there is no firewall other than that directly connected computer (when you get routers from ISPs the router is the firewall - it just uses a light Linux distribution where iptables and netfilter act as the firewall).

Would you want to provide Internet access to more devices through LAN you would need a second network card in your computer that would act as a in/out interface for a switch to connect more devices. In that case you would probably need to setup a DHCP server and create a new IP range/network (this also requires to adjust routing again to provide connectivity to clients in that DHCP IP range/network).

So all of that is absolutely nothing for any normal Internet user. It's more of a enterprise solution. We do such things at work because we need a lot more control over the connection. We have business VDSL Internet connections on various sites and use enterprise DSL modems by Draytek and Ubiquity EdgeRouter Pro/Lite routers for routing and firewalls.


The easiest thing to do in your case would be probably to simply disable WiFi on your router either via a hardware button on the router or by accessing the web panel of the router. That is of course when you're not going to use WiFi at all.

WiFi alternatives are not really existing. The only thing I can think of is actually doing Bluetooth Thethering. That however is probably even worse than using WiFi and a by a whole lot slower. Unfortunately also Bluetooth operates on the same frequencies that WiFi 2.4 GHz is using. That would mean signal distortion and performance issues.

If you need to connect clients via wireless to your Internet connection by the means of the average Internet user with a ISP router and so on... you have no real alternative than using WiFi. Lo and behold! I'm speaking of really usable alternatives. There is no really usable alternative. You can hack something together that would probably be a hell to use, slow and not stable at all. And some solutions might actually be expensive because you need additional new hardware in all devices.


The only thing I can think of that would work and that also is mentioned in @Manal linked article is to buy 4G LTE plans and get these small 4G LTE USB thumb drive modem/routers that you can plug into the computer to use the mobile Internet connection. That again is wireless though but not on the WiFi levels or standards.
