Frequently Asked Questions

How can I use the dormitory's Wi-Fi network, "kollegium"?

In the building K0-1-2-3 and 4 you can use the "kollegium" Wi-Fi network. Your login credentials are identical to your szewlan/eduroam username/password. In Széchenyi University, your username is your_neptun_code@net.sze.hu and the initial password is your birth date (only 8 digits: YYYYMMDD) and your Education ID (11 digits, you can check it in Neptun, on the My data/Personal information page).

So if your Neptun code is ABCDEF and you were born in 1990.12.23 and your Education ID is 12345678901, your username is abcdef@net.sze.hu and your password is 1990122312345678901. If you had an eduroam username in your sending institution, you can also use that username/password on the kollegium, eduroam and szewlan WiFi networks.
Required setting: security protocol WPA2 (EAP method: PEAP, Phase 2 authentication: MSCHAPv2, CA certificate: do not validate)
On Windows systems you can set the desired parameters automatically by running a setup tool wich can be found in the downloads section in this site (Wi-Fi profil - kollegium). The script requires administrator privileges.

There is also a setup tool, which can help set up your computer: https://cat.eduroam.org/?idp=651

You can change your eduroam password here: https://acs.sze.hu/secure/login.htm
In this site, you can also check your credentials validity. If you try to log on, the following messages could appear:
  • Error: Login Failed. Your username is exists in the system, but the password that you provided was wrong.
  • Error: Login Failed: Invalid User Your username is not exists in the system. The user generation is a manual process, so it is normal during the first few weeks of the semester.
If you forgot you password or if you would like to inquire about the non-exists user, you can do this at the site help.sze.hu

What is NAT? Can I use it?

Network Address Translation is a way of sharing your internet connection to other devices. In the dormitory, any kind of sharing (hotspot, for example) is strictly forbidden and leads to the immediate ban of the source IP address for at least 1,5 hour.
If you would use new devices, you should register them under registered devices and IP addresses.

If your IP address is got banned, and you stopped the sharing or whatever caused the NAT, you should let us know about it in the error reporting area. The unblocking of the addresses is a manual process.

I had a problem while I was try to login or register to the user.sze.hu site...

You can use the eduID centralized directory identifier in many sites on the University. This system is not managed by us!

How can I find my device's MAC address?

Windows 2000/XP/7:
Start menu, Run: cmd.exe type in ipconfig /all
Here you need to look at the lines starting with Physical Address. There may be more than one line. If you are connected to a network via UTP cable you should choose one under Ethernet adapter Local Area Connection, or if you use Wi-Fi, then the one following Wireless LAN adapter Wireless Network Connection.

Windows 8/10:
This process is similar to the previous version of Windows, but the command line can be started on the desktop by right-clicking the Start menu icon.

Linux distribution:
Terminal: ifconfig
Here, lines with HWaddr contains the relevant data.

OS X:
Terminal: networksetup -listallhardwareports
The MAC address is displayed in the line starting with Ethernet Address.

Can I use my own hotspot or WiFi router?

We do not recommend the use of TP-Link routers with the factory default software, because they tend to overload the network, which lead to the blocking of the room's wall socket without any warning.
If you would like to use any TP-Link router, you have to change it's firmware to OpenWrt or DD-WRT.
Before you change your devices firmware, you should be aware of the following:
  • Product support of OpenWrt or DD-WRT firmwares (you can check it on the links before).
  • The replacement of the firmware is risky, in case of a failure the device may become unusable and may result in loss of warranty (NetClub assumes no liability for any of the cases above).

Központi kollégium és Multifunkciós épület:

The use of a router is only possible with the Wi-Fi radio turned off! Erre az interferencia és a csatornák túltelítettségének elkerülése érdekében van szükség. A többi beállítás megegyezik az alább foglaltakkal. If you would like to use WiFi please check the following article: How can I use the dormitory's Wi-Fi network, "kollegium"?.

Külső és Famulus kollégium:

Ha megfelelő firmware van az eszközön, az alábbiakra kell ügyelni:
  • A WAN portra ne csatlakoztass semmit. Ezeket az eszközöket is olyan módon kell használni, mint a switch-eket, azaz úgy megfelelő az összekötés, ha a fali aljzatot is a LAN portok valamelyikére csatlakoztatod. Ha a WAN portra kötöd a fali aljzatot, akkor a router nemcsak elrejti a kollégium hálózata elől a gépedet, de mellette még NAT-ol is, ami letiltást von maga után.
  • Állíts be megfelelően bonyolult jelszót.
  • Ha van ilyen beállítás, akkor a routert DHCP kliens, vagy Access Point üzemmódra kell állítani.
  • Ha van WiFi rajta, akkor állíts be titkosítást, illetve az SSID a szoba száma legyen (pl.:Ky/xxx, Sxxx/y).
  • Mielőtt csatlakoztatnád a fali hálózati aljzatra, kapcsold ki rajta a DHCP szervert és ha van olyan menüpont, akkor a NAT-ot is.
    Figyelem! Egyes routerek már kezelik az IPv6-ot is. Ha találsz beállítást rá, érdemes kikapcsolni, illetve mindenképp kapcsold ki az IPv6-ra vonatkozó DHCP szervert. DD-WRT és OpenWrt esetén ügyelni kell az IPv6-ra, de előfordulhat gyári szoftveren is.
A helytelen beállítások a szobai végpont figyelmeztetés nélküli, automatikus letiltását eredményezik! Ennek tudatában javasoljuk, hogy használjatok switch-et a megosztásra, mert ennél az eszköznél nem jelentkezhet semmilyen probléma sem, és még olcsóbban (2-3000 Ft) hozzá is lehet jutni a boltokban.

Fontos: Mi csak a hálózati végpontig szolgáltatunk. Tehát ha nem tudod beállítani a routert, akkor vagy ne használj ilyen eszközt, vagy keress olyat, aki ért hozzá. A NetClub-nak nem feladata a hallgatók privát eszközeinek a karbantartása/beállítása.
