I just moved into a student dorm for a semester abroad, and beforehand I emailed them asking whether they had ethernet ports to plug my router into (I use it to connect all my devices, and for WiVRn VR streaming). They confirmed that I could, but now that I'm here the wifi login portal is asking me to accept these terms from the ISP, which forbid plugging in a router. There's another clause that forbids "Disruptive Devices" entirely, defined as:

“Disruptive Device” means any device that prevents or interferes with our provision of the 4Wireless to other customers (such as a wireless access point such as wireless routers) or any other device used by you in breach of the Acceptable Use Policy;

So what are my options? I don't think I can use this service without accepting the terms, but also I was told by the student dorm support that I could bring a router, which contradicts this.

EDIT: some additional context:

  • dorm provider is a company separate from my uni (they have an agreement but that's it)
  • ISP (ask4) is totally separate from dorm provider, and have installed a mesh network that requires an account. On account creation, there are many upsells including one for connecting more than one device. The "free" plan only allows me to sign in on a single device, and I can upgrade to two devices for 15 pounds.
  • ethernet requires login too
  • VR streaming requires a high performance wifi 6 network, which is why I bought this router (Archer C6 from tp-link)

Is this a problem with 5G networks? There are more channels and they don't go through walls as well, right?

[–] [email protected] 2 points 2 months ago

Tl;Dr It's complicated.

Do you mean 5Ghz networks (5G is cellular tech, after all)? If so, 5Ghz can travel through walls, but it doesn't travel as far, because there's an inverse relationship between range and channel width. Also, 5Ghz has a shorter wavelength; some of the signal's light will get absorbed by the walls, but not all of it.

Ultimately, you'd still have the same problem: too many radios sharing a limited range of frequencies on a band would interfere with each other if sufficiently close.

It would be akin to having everyone playing different music at full volume on their own personal speaker; you'll inevitably hear the people closest to you. Radios can't "hear" anything outside of their chosen frequency (channel), but if other people nearby are also on that channel, you might catch or lose some unintended packets, triggering a resend event (TCP) or causing stuttering/lag (UDP).

The number of channels available for 5Ghz varies by country, with the EU having the most, iirc. In the US, if you try to force your router to use one of the blacklisted channels, your devices will likely not connect (unless they were directly imported), despite being able to use the 5Ghz spectrum.
