The uni is not at fault here, the dorm is a separate entity that just happens to have a deal to keep some rooms for exchange students like me. The dorm is from iQ Student Accommodation (who told me I could bring a router), and the ISP they use is ASK4 (whose T&C you are seeing).

Switches are also explicitly banned as they allow bypassing the device limit.

While I see where you're coming from, I do need to clarify two things:

• I use VR mainly for two things: Beat Saber, and sometimes C++ game development (my degree). I can't develop on-headset because of the limitations Facebook imposes, so I am stuck with streaming. I am taking my own path through these studies, for example I rewrote all the assignments and engines to CMake and then Linux which has allowed me to learn a whole lot more than if I simply followed the classes. I wish to mess with networking as another extension to my studies, as it's not covered at all and now is the time I have dedicated 100% to learning (vs later in life).
• I didn't really choose this university: I chose to do an exchange program for a semester and this was the one option that matched my interests/degree. And the uni seems awesome so far (we haven't started courses though). The dorm is a separate entity from the uni, but they do have a deal to provide rooms for half a year for exchange students. So this dorm was my best option to avoid a yearlong contract.

Thanks. I do unfortunately need wifi to do wireless VR streaming... I guess I need to find a way to tune it to interfere the least, but this is a whole alien world to me.

y e p, I feel your pain (but I know way less about networking than it seems like you do haha, still haven't made the jump to ipv6 myself)

Woah, that's really cool. I'll contact my uni to ask about it and I guess for now use a phone data hotspot and skip on VR.

Interesting about hiding SSIDs, I never knew why that option existed. I'm here on Erasmus so I don't want to risk too much by knowingly breaking rules... them triangulating it to my room and starting a legal case or something sounds real scary.

Yeah that's the thing... the max devices is one, unless I pay a fee (per device I think). This third party that manages the internet offers a bunch of upsells in the account creation for stuff like more devices.

My Ubuntu server (which has been working for a few years now) recently asked me in a full-screen prompt while updating something about GRUB. There was a list of partitions with just one element, which is the partition that GRUB os on. I was focused on something else so I just hit enter, but now I am really scared to reboot it. Is there any way to pull this back up or to double-check that everything is ok with the machine?

Yep! You can just paste the URL of the blog into your reader (or try https://blog.allpurposem.at/feed/ if that doesn't work).

I set up Arch manually, following the ArchWiki guide. Over time using it though, I must have made some customizations that were incorrect and caused it to break.

I use Bitwarden and, though all the features are very nice (self hosted Vaultwarden), the clients are really bad. The autofill is super inconsistent on Android. The app takes 20s+ to load on my Pixel 3a. You can't trigger a sync from the quick autofill menu, you have to open the full app. The "desktop app" is just an embedded browser. I really want to like it, but it doesn't make it easy.
