This is a community dedicated to all types of computer networking (physical/virtual/cloud/etc.)

Computers use common communication protocols over digital interconnections to communicate with each other. These interconnections are made up of telecommunication network technologies based on physically wired, optical, and wireless radio-frequency methods that may be arranged in a variety of network topologies.

Set devices on a different IP class in LAN (discuss.tchncs.de)

As the title alludes, I have two devices that I would like to connect to my LAN (a TC - wired; and a phone - wireless), but I would want them to be connected to a separate subnet, so they wouldn't communicate with the rest of my LAN.

Currently I have those two wirelessly connected via my router through a guest network, which automatically assigns them on a different subnet, but the router (provided by my ISP) is pretty crap, and the wifi networks either drop, or have bandwidth issues quite frequently. Unfortunately, due to the router not being the best, it doesn't allow me to assign IPs for those two devices that are outside the LAN subnet.

I would like to be able to connect the TC via ethernet instead, to guarantee the best connection, and perhaps link the phone with a separate wifi network, or perhaps just use data connection, thus taking it out of the LAN completely.

To achieve this I was thinking of getting a second router (second hand perhaps), flash OpenWRT on it, and use it to connect just those two devices.

Another option I've heard of would be to use a managed switch which allows me to set it up to connect devices on another IP class.

Could anyone let me know what would be the best and affordable option for this purpose?

Thank you in advance!

My bad, I forgot to mention that the ISP provided router does not allow me to assign the devices IPs that are outside the current subnet. Edited the post for clarity. Are you aware of any routers that would allow me to do that? Preferably with OpenWRT support?

I think getting a better router to replace the crap one from my ISP might be a better move.

No need to touch the router. The IP Configuration would be done on each device.

What are you trying to do anyway by having the devices not in your normal network?

I'm not able to set the IP manually on those two devices, I don't have that option. Those two devices are what I use for work, and I would like to keep them separate from the rest of my home network.
