I just bought a

TP-Link Archer D7 AC1750 Wireless Dual Band Gigabit ADSL2+ Modem Router

And i am having a lot of troubles which is really pissing me off. First off, there are 2 wifi's and i connect to one for about 30 minutes but then the internet just suddenly stops working and i have to connect to the other one and if that internet isnt working i have to connect back to the original wifi. Also my ethernet cable internet connection doesnt work anymore which also annoys me. Any solutions?
