We moved into a house using the netgear R6200 wifi and the laptop will connect to it but our android tablet and samsung cell and LG smart tv wont . authentic password issue
The first thing I would do is log into your Netgear router and reset the wireless access password, then try reconnecting with your devices. You might also want to check that your network isn't limited to wireless N only, unless all of your devices are wireless N (otherwise, wireless G devices won't connect).
If that doesn't work, then you might need to try a factory reset on your router.
Hope this helps.
