I used OpenWrt at home before and am now living away at college. I wanted to use a Chromecast on the college internet Eduroam, but of course it is not able to connect to enterprise WPA. Thus, I was thinking about creating a routed client for just the Chromecast to live on in my room.
Here's the dilemma and things I have thought about:
The university recently just stopped allowing ethernet ports to be activated, so anything I do would have to be masqueraded and use a wireless connection as my WAN.
Servicenet allows me to register MAC addresses and connect them to it and use them. It filters out streaming devices like Chromecasts, so it wouldn't work anyways.
However, if I were to use a RPi 4b, I can add that to the MAC address filter and use Servicenet which is has no WPA authentication in general. I'd then probably just buy a USB WiFi dongle so I can output the network I could then connect to, using onboard RPi WiFi as WAN
Would this be a viable alternative, or should I consider buying a router?
If I were to buy a router for the room, which should I buy in order to still use a routed client connection where I cannot use any ethernet at all. This is the most important part is that I cannot use any ethernet.
Routed client is rather unlikely to be an option, as I don't see IT adding a static route for you - meaning you'd end up with masquerading anyways.
Don't buy a RPi for its wireless capabilities (neither onboard, nor USB), more traditional wireless routers are much stronger in this regard (and cheaper), especially the tri-radio options might come in handy (e.g. map-ac2200).
Just a clarification, you still think it would be possible to have this setup in general if I had no static route and had masquerading?
Do you think tri-radio is the way to go in this case then? Know any semi-cheap options? The ones I was thinking of that I could get semi-used and for cheaper would all be Broadcom chips so other suggestions would be appreciated!
While you can surely find a technical solution to work around this, please make sure that you're still complying with the terms of service of your university. There is probably a good reason for filtering streaming devices.
