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)
So most dorms don't want you using your own routers because a bunch of student routers causes A LOT of inference.
You should probably reach out not to the dorm folks but the university networking folks as they're the ones that will ultimately make the decision on whether or not to turn things off/disconnect you.
A cheap networking switch would probably be okay by them to get some more wired connections in your dorm room (routers aren't really a great way to do that).
As a secondary concern, using a router will cause a double NAT for all your connected devices (universities don't operate in the way ISPs do). That could cause some weird networking shenanigans, particularly for anything peer-to-peer like online games.
That's good advice, however this dorm is not part of my uni (just a partner to provide housing) and the internet provider whose T&C I'm expected to accept and sign up for 1y of are a totally separate legal entity, that has a bunch of upsells for stuff like "connect more than 1 device" (which my router/AP would basically be bypassing, and I think that's what these clauses are about).
About the interference, is it possible to limit it severely while still having a reliable connection just within my room? I only really want to connect:
You can do a few things to reduce interference if the device broadcasting the signal supports it. Unifi APs support these settings. Most routers with WiFi probably do not support transmit power.
Adjust transmit power to lower setting
Higher the frequency, shorter the range (but that frequency may be highly used in the area), so #3 is the better option
Analyze the frequency usage and picking a frequency that is least used
If 2.4Ghz band isn't necessary disable it and only use 5Ghz since it's a higher frequency it again has a lower range.
You could also faraday cage your room so the signal won't leak out, but thats probably more work than its worth.
You may want to update your OP. Not being part of the University, makes a HUGE difference and will affect your options. Typically, when people say "dorms" it's direct University provided housing.
Options in this case:
Just play dumb, nobody expects anyone to actually read TOS.
Setup a router level VPN.
Buy your own hotspot for Internet access. (May be cheaper to just pay for additional devices)
