Recently my apartment moved from having individual modems (with our own router/wifi network) to this Spectrum Community Solutions building wide network. Everyone can connect to the network anywhere, it's not apartment specific although there does seem to be a router in every apartment for connection (this router also doesn't have ethernet ports which is a gripe of mine).

Everyone connects to the same network (same SSID), and same wifi password. However, each resident then has to enter their own username and 4 digit pin (seems too short to me) to access the internet. Their website here claims

All data is encrypted, credentials are protected, connections are private and guests can’t access the private-resident network without your permission. Devices on your private resident network will be able to communicate with each other, but no other resident user will be able to “see” your devices.

Now I'm no security expert, but if two people happen to be connected to the same router can't someone still easily implement a scan/man in the middle attack on the other computer? Even if the data is encrypted, I don't see how they could prevent a scan of the connected devices by a malicious individual.

As a bonus question, their brochure says not to connect my own Access point but I just tried connecting a router to their big switch box they installed in my closet. Internet worked although i still had to sign into their login page with my 4 digit pin. Do they have a remote way of knowing if I am using an additional port on their switch?

  • You'll have to ask if this is using "WPA2 Enterprise" or not. – forest May 11 at 1:45
  • After a brief google search of WPA2 Enterprise, it looks like WPA2 enterprise involves the additional step of individual username/pwd to access internet. Since Spectrum's network does require this, does that mean it's Enterprise? – exiledwolf May 11 at 1:56
  • Most likely it's not enterprise then. Are you using a VPN supplied by them? If you aren't using that either, then I can't imagine how the connection is protected from someone who knows the Wi-Fi password and is in range, assuming it's using standard WPA2 Personal. – forest May 11 at 1:58
  • No no vpn, although i could get my own I suppose. Sounds like the solution is either vpn, connect my own router to their switch and hope they don't notice, or...move out. – exiledwolf May 11 at 2:03
  • Looks like it. I'm refraining from answering because I don't know the details about your specific apartment's setup, but from what you've said, it does seem very much like you'd need a VPN to protect from other users on the network who know the Wi-Fi password. – forest May 11 at 2:04
