My model is Lenovo Tab 4 8 Plus 4G/3G Voice, Aurora Black8" FHD, Snapdragon, Octa-Core; Up to 2.0 GHz, 3GB, (TB-8704X). CommunicationsWi-Fi 802.11 a/b/g/n/ac, dual-band, WiFi Direct, hotspot, Bluetooth 4.2.
The tablet connects to my WiFi, and internet will work for a few minutes, but shortly thereafter the internet will stop working.Disconnecting and reconnecting will get internet working again, but after a few minutes the same thing happens. I try with several different 5ghz networks(free and with password) but nothing.
