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)
Yeah, the interference argument is fair, but I think this is also the ISP (totally separate third party) trying to protect the paid plans they sell for connecting more than one device...
It's definitely 90% of the reason
So it's a network operated by a third party? That's interesting. The handful of universities I've been to maintain their own.
Where I went to school, originally the dorms were on the university network but a year in they offloaded us onto regular, commercial ISPs. The change was great for us since the university network was very strict on stuff like torrents (using DPI any torrent, even legal, got you disconnected for 24h)
My university had student apartments, each had their own router. No weird rules since it wasn't the university's network at all, it belonged to whoever lived in the apartment. Full router access, connect whatever, put it in bridge mode and connect your own if you want.
If there's enough space between them, it would be less of an issue. If it was in a multifamily high rise with hundreds of units, I would expect it to cause issues.
Is this a problem with 5G networks? There are more channels and they don't go through walls as well, right?
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.
In that case, just set up a router level VPN. The university probably doesn't give a shit. Which is why the help desk IT kid said it's fine, probably.
It's the 3rd party ISP just being greedy. The ISP may not even care as long as you're not running an insane amount of traffic through it. Often this type of stuff is added to TOSs to allow them the option, if you're being a bad actor.
