Recently I've noticed that the connection to my 3 children and my wife's mobile keeps on dropping.
This seems random and switching their phones off doesn't solve the problem. The only solution is to power down the Hub and then they can reconnect. It happens to all four of them and not at the the same time. They all have android phone from different brands. It's driving me crazy
Do you know if the 2.4GHz and 5GHz frequencies use the same password or not? They should both be distinguishable by the -2g and -5g endings to the network names. If the passwords are the same for both please change one of them and reconnect your devices.
Navigate to 192.168.0.1 via your browser.
Log in using the access info on the base of the Hub (or use your own password if you've already changed it from the default).
Click on Wireless Network Settings.
Change the Passphrase or Security Key for one of the frequencies.
