I'm living in a university hostel and trying to connect my desktop PC through the Ethernet jack in my room because it doesn't have built-in Wi‑Fi. Windows reports "Unidentified Network" and "No Internet." Running ipconfig /renew times out while the computer assigns itself a 169.254.xx.xx address with no default gateway. Campus Wi‑Fi works on my phone, but it blocks Steam and Riot Games traffic, and using Cloudflare WARP over Wi‑Fi results in too much latency for gaming. Could a software setting or network trick activate the wired connection, or does the port need to be enabled by campus IT? If wired access isn't available, what is the best way to get a lower-latency connection through the campus Wi‑Fi?

Contact IT and describe the symptoms without guessing at the cause: mention that the wired adapter gets a 169.254 address, DHCP renewal times out, and no default gateway is assigned. They may need to activate the jack, allow-list the computer, or provide a specific authentication or configuration procedure. Don’t try to scan the campus network or set a random static IP, since that can violate policy and still won’t provide a usable route.
If the university blocks game traffic at its firewall, switching from Wi‑Fi to a campus Ethernet jack probably won’t bypass that restriction. Wired and wireless networks may use different policies, but only IT can confirm. For gaming over Wi‑Fi, use the official network configuration, connect on the 5 GHz or 6 GHz band when available, stay near an access point, and avoid WARP or other VPNs unless the latency is acceptable. A personal router or hotspot may also be prohibited or have its own data and latency limits.
A 169.254 address is an automatic fallback address. It means your PC has detected a local Ethernet connection but did not receive an address, gateway, or other settings from DHCP. The port may be disabled, assigned to the wrong network, or require your device’s MAC address to be registered. Those are administrative issues, so campus IT needs to check the wall jack and switch configuration.
