I have now received and setup my new 'Android 10' Lenovo tablet & transferred all content from the 'Android 8.1' Samsung A6 tablet.
The Lenovo is connecting instantly as are all my Apps, tabbed websites & mail etc.
SPEEDTEST registered downloads of 341 & 342.8 mbps on the Lenovo compared to the Samsung which on first & third attempts 'failed to connect', but on the second attempt had registered 0.03mbps 🤬.
My Android Xiaomi Redmi Note 10 Pro Mobile placed adjacent to the tablet registered 321mbps.
CONCLUSION: The 5 year old Sammy software can't cope with the new HUB 5 WIFI 6 specification so my decision to purchase a new tablet was justified.👍
