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)

Because that router will be broadcasting DHCP signals and offering IPs, conflicting with the authorized DHCP servers on the network. This wiki article will probably explain it better. I’m not so good with the words an such.

A consumer router only operates DHCP on the LAN side. Presumably one would plug the WAN side into the university network, making this a non-issue.

Some of my other replies address that. Worked in IT on a college campus, and every class will have at least a few clueless users who just plug the cables into the LAN ports.

Makes sense. Would that not be trivially mitigated by just blocking dhcp responses from unapproved servers on the switch though?

I don’t know much about networking but that page seems to be about someone else setting up a dhcp server without the knowledge of the administrators or the users. In op’s case the concerns about mitm attacks don’t apply and the other concerns sound like problems that could arise in cases of misconfiguration or if the users aren’t aware they’re connected to a different network. I also couldn’t see anything about it affecting the main network’s performance

I mean, it’s all right there in the first two paragraphs. Keep in mind that by DHCP server we aren’t talking about something specifically set up by people with malicious intent. A home router is a DHCP server when not configured for pass through. Students who don’t know how routers actually work (we can’t all be IT nerds, lol) plug them into their dorm Ethernet jack, and now you’ve got an unauthorized device offering IP addresses that conflict with the authorized DHCP servers, which can quickly start causing issues with any new devices trying to connect to the network, and existing devices as their DHCP leases expire. Also keep in mind that we’re talking about a college network that will likely have local network resources for students like shared drives that would not be accessible to anyone connecting through the rogue device. Your IT department will quickly start getting complaints about the network that are caused by an access point you have no control over.

I see, I thought routers knew not to do dhcp on the Wan port
