Is it possible to connect a PC bypassing the router?

Question

linux

The point is that I want to connect a WiFi router (TP-LINK TL-WR740N) in parallel to the "Main PC". Is such an approach possible?
I want the direct connection to the "main" to remain in order to be independent of the operation of the router and not cut the speed if something happens. But at the same time, let the "home server" be connected to it (I think to put Linux on the server).
Is this approach realistic and will it not cause complaints from the provider or other devices?
And can I easily connect from the "main" to the "home"?
Here is an approximate connection diagram:
Maybe at the same time and tell me how to implement it better?
ZY: I think to install DD-WRT firmware on the router. Does it make sense?

Answer 1

Complicated scheme. But it is realizable by buying two ip-addresses from the provider. One is broadcast to the main PC, the second to the router.
In this case, the speed will still be shared between the devices, since they are all on the same tariff and share a single channel.
In my opinion, it is easier to implement the usual scheme, where the wire from the provider is inserted into the router, and all other devices are already connected to the router.

Answer 2

You can simply connect the Main PC to the Wi-Fi Router with a patch cord, the 740 model honestly gives up to 100Mbps via cable. But in the future, if you install a Home server, the speed will still be shared.

Answer 3

Such a thing will only work with 2 IPs and that's it

Answer 4

It depends on which provider and router.
On a normal router and a normal provider - a matter of two minutes.
