On the Samsung branch of the US Reddit forum, users are actively discussing wireless networking issues when using Wi-Fi 6 (802.11ax). For some phone users, the standard message “Connected, no Internet access” is displayed.
Actually, the problem is not new, it has been observed on some phones almost out of the box. Moreover, there is no dependency: for example, in the case of two Galaxy S23 Ultras purchased at the same time, only one of them has a problem.
Users note that it is observed on various routers and Wi-Fi 6 networks, both at home and at work or elsewhere. So it’s about phones.
