Network Troubleshooting (Start Here)

A quick checklist for getting online and reaching LAN services.

Most issues are either cable/port, DHCP, or something on your PC. Work through the sections below in order.

First, check Known Issues. If it’s a global outage, you can’t fix it locally.

Basics

  • Ethernet cable plugged in firmly (both ends), link light visible on your NIC
  • VPNs and “network tools” disabled
Warning

Please don’t bring your own network hardware:

  • No personal switches, routers, or Wi-Fi access points
  • No internet sharing from your device
  • No DHCP servers or network scanners

Diagnose connectivity

Open the LAN portal: spawn.ctrl-alt-gg.hu

Portal loads?What it meansNext step

Server red / downGlobal outageTell staff

If everything is broken for many people simultaneously, tell staff first — don’t spend time fixing locally.

Renew your IP address

If the portal doesn’t load after replugging the cable:

Windows:

ipconfig /release
ipconfig /renew

Linux:

sudo dhclient -r && sudo dhclient -v

Make sure your adapter is set to Automatic IP (DHCP) — static IPs will not work on our network.

If your port goes dead after working for a while, you may have connected too many devices. Ask staff to re-enable it.

  1. Check Known Issues first -- if it's listed, we already know.
  2. Post in #support on Discord with this info:
    • Seat number (e.g. Row 4, Seat 12)
    • What's broken, one sentence
    • What you already tried
    • Screenshot or error message
  3. If no reply in 15 minutes, come to the organizer desk.
