    1. Most of the time, you can just click the WiFi icon in your taskbar, choose SiliconHill from the list and connect like you do with any other network. Only insted of password, you will be prompted to enter username and password. In the rare case this does not work, follow the instructions below:
  2. Remove old SiliconHill network profile (if exists)
    1. Use shortcut Win+I to open settings.
    2. Go to Network and internet → WiFi, and choose Manage known networks
    3. Choose SiliconHill in the list and click remove.
  3. Create new WiFi profile

    7. Confirm all windows with OK until you are left with this one. Then close it. :
  5. We connect to the network. If we have issues with connecting, we first go back and check the password and enter it again.

Android

Select EAP methot to PEAP, PHASE 2 verification to MSCHAPSv2, fill in username (identity) and password (same as for IS). Anonymous identity stays empty.

As a domain name, usually sh.cvut.cz is fine, but some devices need ldap.sh.cvut.cz.

Before connecting, you have to choose CA certificate. There are 3 options.

Před připojením je ještě nutné vyplnit pole Certifikát CA, existují 3 možnosti:

  • Use system certificates (should work with Android 8.0 and newer. Use ldap.sh.cvut.cz as domain name.
  • Download and install certificate from CA at https://www.identrust.com/node/935. Then the certificate will be shown in this menu under the name you choosed. Use ldap.sh.cvut.cz as domain name.
  • INSECURE OPTION - Do not verify. Although this option is insecure, it's widely used amongst users. To parahprase https://man.fit.cvut.cz/ict/eduroam/: If you do not provide RADIUS server name or disable certificate verification, your login credentials can be spoofed by someone who can then pretend to be you.

Disable MAC randomization

Andoid 10 and Windows 10 often have MAC randomization enabled. However, our network allows only known MAC addresses to connect, so this options needs to be disabled.

Android 10+

Pro zjištění MAC zařízení je potřeba ho připojit k nějaké síti (např. SH_registrace) a následně v nastavení dané sítě vybrat “Použít MAC zařízení”. Následně zobrazovaná MAC je již ta, co je potřeba zaregistrovat v ISu. Nyní lze již zařízení připojit k síti SiliconHill. Je však potřeba randomizaci MAC vypnout i pro tuto síť.

iOS 14+

Pokud se na iPhone / iPadu / jiném iZařízení objeví problém s připojením k síti SiliconHill, je třeba vypnout “Soukromou adresu” / “Private address”, viz screenshot níže.

Pokud se k síti nelze připojit již zezačátku, je třeba provést manuální setup sítě podle základních informací + vypnout “soukromou adresu”, jako v již uložené síti.

Windows 10

Kroky k vypnutí ranodmizace:

  1. První 3 kroky jsou stejné jako pro odebrání profilu WiFi sítě viz navod_na_pripojeni
  2. V rozbalovacím menu Používat náhodné hardwarové adresy pro tuto síť vybereme Vypnuto
