Symptoms

Network connectivity interruptions may be experienced when moving between access points with the same SSID while connected with a Realtek 8852BE wireless card. After roaming between access points, the computer may remain connected to the network but experience limited or no external network connectivity. The issue may occur when roaming between access points with the same wireless network name, resulting in the network connection becoming unavailable. Also, all SSID names may disappear from the wireless network scan list. The issue may also occur after unlocking the laptop. The wireless icon still shows connected but there is no Internet connection. If this issue is experienced, confirm that the signal strength remains strong while moving between access points to ensure that this article applies.
