I've not had any problems. Have you tried reseting your network settings? Just watch out tho if you do you will lose all saved network passwords and Bluetooth connections plus other connection settings.....
The issue can be caused by the Wi-Fi access point.
Try resetting your router if possible, then go to Settings > Connections > Wi-Fi > Tap the Wi-Fi network in the list > Forget. Now tap the Wi-Fi in the list of available devices > Enter correct details.
If that won't help, please report the issue via the Members application so that our developers can analyze it
