Ich habe seit Monaten Probleme über mein lokales WIFI einen beamer mit chrome cast anzusteuern. Das hat drei Jahre lang geklappt, bis vor ein paar Monaten.
Setup: Swisscom router mit GSM booster. Internes Ethernet an Netgear Switch. Ethernet an iMAC OS 10.3.6 Dann über Wifi Hotspot an chrome cast (und ja, eingestellt auf 2.4GHz).
Der ganze setup klappt wenn ich über mein iPhone/iPad am Telefonnetz streame. Funktioniert aber nicht wenn Datenverbindung über Internet Router geht. Chromecast support macht dafür eine Spezifische Router Einstellung verantwortlich: eine Einstellung "AP isolation" oder "guest mode" or"client mode" muss AUSGESCHALTET sein, sonst funktioniert das Ganze nicht. Ich kann aber in den Router Einstellungen, die mir als Nutzer zur Verfügung stehen einen solchen "Schalter" nicht identifizieren.
Google support Anweisung:
Keep in mind that resetting or making changes to your router settings may have unintended consequences. If you need help or have questions or concerns, contact your router manufacturer or internet service provider (ISP).
- Check if your router or wireless network uses AP isolation mode (also known as "guest mode" or "client mode") or an authentication page (also known as a "captive portal"). If enabled, these settings can prevent your Chromecast device from properly connecting to your mobile device or computer. Be sure to disable these features prior to setup.
- Be sure that Multicast, UPnP, and IGMP are enabled on your router.
- If your router is running DNS software, be sure to enable the following public Google DNS IP addresses: 8.8.8.8 & 8.8.4.4
Here's some additional information to keep in mind as you troubleshoot the issue:
Chromecast (1st generation) is only compatible with 2.4 GHz Wi-Fi 802.11 b/g/n Wi-Fi networks, so it won't list 5 GHz networks when setting up the device. Please make sure the Chromecast is using the 2.4 GHz band. Other Chromecast versions are compatible with both 2.4 GHz WiFi 802.11 b/g/n WiFi networks and 5 GHz networks, so you will see both when setting up the device. If you have a dual band router, you must disable AP isolation. Other devices such as your laptop/computer can use the 5 GHz band; the 5 GHz band will maximize performance when using the Cast extension to cast a tab.
If you're having trouble connecting to a 5GHz connection on a router that is running DD-WRT firmware, please change the wireless mode setting to "mixed" and then try setting your Chromecast again
Hidden networks: If your network is hidden (i.e. does not broadcast its name/SSID), you'll need to manually input the network name and password. To do this, go to the network selection drop-down list, select "Other," and manually input the name and password.
MAC address filtering: If your router has MAC address filtering enabled, you'll need to add the MAC address of your Chromecast to the list of filtered devices.
During setup, from the "Connect to Wi-Fi" screen, please tap the 3 dots
located in the top right corner.
Tap Show MAC Address.
Security: Chromecast supports WEP, WPA, and WPA2 wireless security protocols. These protocols prevent uninvited guests from connecting to your wireless network, and encrypt your private data as it is being transmitted over the airwaves.
After you've adjusted your router settings in accordance to the information listed above, please try setting up your Chromecast device again. If you have any further questions, please reply to this email directly.
