After many hours of searching for a solution to my problem, I gave up. Already translators what's going on.
I have a Cavion 7.1 quad tablet with Android 4.4.2, firmware v2.0, which I want to connect to the sagecom fast 2704 router with the internet from orange. The problem is that, although he sees the network, after entering the password, which is 200% correct - it only informs about saving the network and either it stays that way or falls into the loop of getting the IP address / authentication. The tablet connects to other wifi networks without any problems. And as for the home network, for the rest of the devices, whether it's wireless or cable - no problems. I have already tried: - connect via WPS with a push-button and with a PIN - change the type of network authentication (most of the time it stops detecting the network) - add MAC filtering / disable it completely - change broadcasting channels - set a static connection when connecting to the network - reset the router / tablet
The router sees the tablet and gives it an IP address I read somewhere that the router and the tablet can have different bit encryption, which is why there are problems, but I have no idea where to change it in android.
