My connection is reasonable/bad on stadia with Chrome. I have a 300+ mb/s connection at home, so thats very strange. The graphics on RDR2 are also blurry, because of the connection I think. I hope you guys have a solution, I tried everything on the support page, for Stadia on Chrome.
WLAN? IaI had some problems at the beginning, especially with the stability and the quality. what disturbs massively is Bluetooth. I removed and deactivated everything that has to do with Bluetooth. I use a weak Chromebook without a LAN connection. Now I have a LAN to USB C adapter. since then there have been no difficulties. It's going great. Maybe that will also help with your devices.
