Connection Issues

[RandomlyOnside]

A few weeks ago I started having connection issues with Stadia and they haven't gone away. We made no change to any wifi and we this issue on multiple computers (chrome) and using chromecast wired or wireless. 

Anyone have any suggestions what could have happened. 

Set ups
Chromecast Ultra with Staida Controller
Asus ROG G14 Laptop
Asus RT-AX92U (Wifi 6 Router)

ISP - Access 3 Media
Modem - Cisco DPC3010

We also have a TMobile hotspot that has better luck. So we know it is something with the internet connection, but at 14ms ping and 148mb dl 25mb up i am not sure what we could try? Any ideas?

Edit OP to include ISP and Model as it is almost confirmed it is an ISP/Modem issue. As i have removed all wifi (even tried multiple wifis) and pluged directly into cable modem (Cisco DPC3010) and still having same exact issue.

Have you tried restarting the modem and router by unplugging them both for 30 seconds?

[RandomlyOnside]

Yep! Def done that several times.

Did you have the same issues when you are playing with a ethernet cable connected?

Found a reddit topic about your laptop with WiFi issues.
Some of them reported they fixed it by updating the bios of the device.

Even when wired directly to my modem i have the same issue. 

If I turn on my T-Mobile Hotspot and connect my G14 to that (via Wifi) I can play just fine. It is a very strange ISP issue that I cannot seem to pinpoint. It really sucks because it was working; bought some games that are now useless.

Ahh no way.

Did you try contacting your ISP about this issue? Maybe they can help you out somehow.

@RandomlyOnside one more thing. Did you try to set the DNS to the Google DNS?

I have read some topics before and some seems to be solved by changing your DNS to the Google DNS. (8.8.8.8 & 8.8.4.4)

Thanks again for the help. 

Yep - my router has google dns. (i'll update the original post).

The ISP has no idea & tried to claim it was Staida/Google's issue. While this could be true, at this point it seems unlikely since it was working (for this whole year, and now 4ish weeks ago it stopped) plus our hotspot works. 

Unless I can point to a specific technology issue or something, I am not holding my breath for a resolution from them. I live in a large building and there is little/no incentive to actually help us as our building negotiates terms with Access 3 Media and they only care every few years when it is time to redo contracts.

So a weird update here.... 

It appears to be working when connected to certain VPNs. 

* Global Protect (business) from an HP laptop

* Proxy Master VPN on a Pixel 4 XL 

The originating ISP is still Access 3 Media, which still doesn't work except in those 2 certarios above. 

The HP laptop is a business laptop for testing, so not a viable long term solution. I am still searching for a VPN that works on my Asus ROG G14. So far I have tried ExpressVPN, with no luck. 

I'll keep updating this as I go along hopefully someone else has this issue or hopefully I can help point someone with similar issue in the right direction.

That is rather strange indeed.

Does the ISP or your router try to check the traffic?

Stadia uses UDP: 44700–44899 maybe you can do something with this info like Port triggering/forwarding?
