Jak poznám, který bezdrátový adaptér či zařízení je vhodné pro připojení do WiFi sítě VŠB-TUO?
Pokud se rozhodujete pro koupi WiFi karty popř. jiného zařízení, které chcete připojit do bezdrátové sítě VŠB-TUO je vhodné (nikoliv nezbytně nutné), aby toto zařízení podporovalo tzv. CISCO COMPATIBLE EXTENSIONS (CCX). U bezdrátového adaptéru, který podporuje CCX (nejlépe poslední, nejvyšší verzi) a je označen logem "Cisco Compatible" je zaručena kompatibilita s nejnovějšími standardy a inovacemi pro použití v bezdrátové síti vybudované na infrastruktuře zařízení Cisco. Seznam takto certifikovaných zařízení vč. verze CCX lze najít na www.cisco.com, v sekci "Cisco Compatible Extensions Client Devices", na stejné stránce naleznete i odkaz na seznam vlastností - "Versions and Features", které jsou podporovány v různých verzích CCX (WPA, PEAP, LEAP, WMM, QoS, RF Management,  Location...). Pokud zařízení na těchto stránkách nenajdete, neznamená to, že CCX nepodporuje a tuto informaci pravděpodobně naleznete na stránkách výrobce daného zařízení.


Používám PDA nebo WiFi IP telefon, funguje v bezdrátové síti VŠB-TUO roaming?
Bezdrátová síť TUONET plně podporuje roaming klientů. V praxi to např. znamená, že můžete hovořit přes IP telefon a přitom procházet areálem školy bez přerušení hovoru. Podmínkou je samozřejmě dostatečné pokrytí signálem WiFi sítě. Skuktečnost, že bezdrátová síť VŠB-TUO podporuje roaming klientů je podmínka nutná, nikoliv dostačující!! Je dobré si uvědomit, že samotná funkce roamingu je hlavně záležítostí koncového zařízení (toto musí neustále "sledovat" dostupné přítupové body a ve "vhodný" okamžik provést asociaci s novým, infrastruktura zajistí na pozadí předání autentizačních informací, zachování IP adresy, otevřených spojení ap.)


My connection stopped working. What should I do?
There are serveral reasons why connection can stop working:

Check your school e-mail you propably have a message there about blocking reasons. Most often reasons are:

  • Violation of usage rules for network VŠB-TU Ostrava, notification from external organizations about violation of the copyright Act (you have propably shared works under copyright law) your connection is blocked and email asking for an explanation has been sent to your school mailbox.
  • Your computer did some suspicious behavior (virus attack and attack into the network).


Is it possible to use wireless part of TUONET to connect from areas outside University?
No, only university campuses are covered.


Why is not safe to use tuonet-simple network?
Network tuonet-simple is a wireless network. Radio signal which spreads access points freely spreads through space and it is possible to catch it anywhere in reach of access point. Unlike "wire" network it can be monitored practically by anyone with notebook and special program equipment.
Log into the network, thus sending your name and password by the network to the point which will verify access permissions to the network is made through protocolHTTP+SSL  thus by "encrypted" version of protocol HTTP, protocol https://en.wikipedia.org/wiki/HTTPS. Authentization to the network itself is before interception (between your device and point which verifies access permissions to the network) protected. In any case, you should choose for access to the "tuonet-simple" network such a password that YOU DON´T USE FOR ANY OTHER SERVICE. Every other communication in the network (logging into ICQ, chat, sending and receiving emails) is NOT ENCRYPTED  this means it can be monitored and abused by third person. In practice it means that user with notebook and special program equipment in the next room can read your mail you are sending right now, your communication through ICQ you are writting at the moment etc.


After installation connection still doesn´t work
If you were connectiong wireless device to the netwrok TUONET-PEAP according to instructions for Windows Vista nd connection is still not working please update driver of the wireless device and then again check "wireless network configuration" according to used instructions:

In case it doesn´t work either please contact your faculty/department administrator, who can help you with the configuration.

If nothing helpes try to connect to the wireless network TUONET-SIMPLE.
This wireless network is notsafe and using it is appropriate as temporary until you solve problem with connection.


Network manager from manufacturer of the adapter is blocking my connection
In some cases running network managers (installed with network card drivers from the manufacturer) are blocking correct connection into the university WIFI network.

  • Set in the options of the network manager that it will not turn on during computer start, shut it down and restart computer so the change can be shown.
  • After restart connection into WIFI network should be set up and working.


Network manager took the functions from Control panels
Some network functions are unavailable from Control panels and it is the same on other computers without this manager.

Network managers installed with drivers from the manufacturer od the network card often take daisplay and control of this network interface and so display/control is limited/hidden from Control panels.

  • If you do not want to use this network manager, set in the options of the network manager that it will not turn on during computer start, shut it down and restart computer so the change can be shown.
  • If you want to use it, set the parameters through this manager.


I don´t connect to the set network
When browsing network connection is important configured order of network (preferred network) in settings in Control panels or in network manager installed with drivers of the network card. Set chosen network as "preferred" and then set "connect to the network if it is available".
