I currently use my 5G mobile phone hotspot to share internet access to a number of devices.
This is impractical for a number of reasons. One being that some devices are wired-only; another that some devices require a constant (local) network connection, even if there's no internet access; the list goes on ..
I have an old PlusNet Hub One router (A sagecom model that supports OpenWRT), and I'd like to set this up to complement my mobile set-up. My questions is, how should I configure my network? I will still need to use the hotspot as a gateway to the wider internet.
- Should I aim to have a separate subnet for devices on the router, or share the hotspot's subnet?
- Should I use the router as a repeater? (Is this effectively the same question as above?)
- How can I get the router wi-fi to both receive from my devices and send to the mobile (internet) efficiently? Won't this cause congestion?
- If acting as a router, how will I handle the disconnection/re-connection to the mobile hotspot, when I inevitably take my phone with me when I leave the house?
In summary, I'm looking for a high-level overview, rather than specific config-file settings. How would I configure the extra router I have to maximize it's potential? Or does it even make sense to do this?
Thanks in advance!
