Google Chromecast wird immer getrennt

[vpnBerl]

Hi,
I have a Vodafone Kabel Deutschland connection and recently reduced the speed from 1GBPS to 50MBPS due to contractual terms. After that, I have a connection problem with my Google Chromecast device.

I cannot connect Chromecast to my WLAN showing an error "Check Internet Connection". I have contacted Google as I thought it was a hardware/software problem of Google device and they replaced my device with a new one.

Again I have the same issue. So I contacted Google once again. Then they asked me (via Chat) to connect Chromecast using HotSpot from my Phone-data. The device got connected to the Hotspot and I could play from Youtube, AmazonPrime, Netflix, and work perfectly without any problem. Then Google suggests me to contact my ISP (Vodafone Kabel) and Quoted the following. 

"Chromecast is a type of Plug and Play device which really requires a strong and stable internet connection. It's not like an ordinary smartphone or computer that is able to work even if you have a weak internet connection.

Doing a Hotspot setup is already a workaround to confirm that Chromecast is not the problem as you were able to cast without experiencing the same issue. You may call your ISP and request to switch your router to a different channel. Let them find and switch yours to a channel where few customers are connected in your area.
There might be lot's of customers using the same ISP in your area that's why even if you see a strong signal but the channel is too crowded, it will result a congestion. "

I don't experience any problem with my laptops or smartphones. But my routers restart frequently. My router and Chromecast device is approximately only 10cm distance. So definitely range is not a problem. 

I don't speak good German to explain all the above problems. Can someone help me?

Hello vpnBerl,

which router do you use and which federal state do you live in? We cannot switch WiFi channels for you, that's something you need to change in the modem GUI. Does the Chromecast use the 2.4 or 5 GHz net? Which speed do you reach?

Kind regards,

Claudia

Hi @Claudia , Thanks.

I use Vodafone TG3442DE router and I live in Berlin Spandau. My chromecast uses the 2.4GHz network. 

"that's something you need to change in the modem GUI."

How can I change in the modem GUI ? 

"Which speed do you reach?"

I dont understand, if you meant my Internet speed, then it will be reaching almost 50Mbps (contractual speed) using speedtest.vodafone.de. A todays result is attached as photo.

Hello vpnBerl,

50 MBit/s sounds sufficient, did the Google colleagues specify which speed the device needs? You can change the WiFi channel in the Arris router via this IP 192.168.0.1. Login with the credentials that can be found on the label on the device. Switch to the expert mode and go to WLAN -> Einstellungen and then change the channels manually.

Kind regards

Claudia

@Claudia Thanks. 

Google doesn't mention any speed, but 50mbps seems to be good. 
But I have found that I need to disable AP isolation when I tried to set up  Chromecast. Can you please guide me on how to do that in my Router? (I am not sure if it is already Turned ON)
I have added a screenshot of an error.

Hello vpnBerl,

I'm not sure if the Arris router has an option for AP isolation. You may try and disable the guest WiFi. If both your WiFis (2.4GHz and 5 GHz) have the same SSID it might be that the mobile device is connected with the 5GHz WiFi while the Chromecast can only use the 2.4 GHz WiFi. So please disable the band steering and use a unique SSID for each WiFi. If you want to do a factory reset you won't need any credentials.

Kind regards,

Claudia

Hi @Claudia 

Thanks, But I have already tried all the options and No solution to my issue.

I haven't seen an option exclusively to disable AP isolation. 

I have no Guest Wifi and have unique SSID for 2.4 and 5GHz. Band steering is disabled by default as I am using 2.4 and 5. 

Can you give me a solution?

@Claudia few weeks before a Vodafone technician approached my house without prior appointment and told that our community/building has some problem with cable internet connection and Vodafone is changing it to Optical Fibre and he wanted to check everything and needed a signature.  As suprise visits are not welcomed, I asked him to take an appointment and come again. But till now, I haven't get any post from  Vodafone asking for an appointment. If he is "really" from Vodafone, then that means there are problems that Vodafone already knew about. If not he is fraud, which doesn't bother me.

Hello vpnBerl,

I can check if there is a problem with the signal. Please send me a private message that includes your full address, the customer number and the date of birth of the contractual partner. Reply in this thread after you sent the PM.

Kind regards,

Claudia

@Claudia I sent you PM. Please have a look.
