NETGEAR problems

I have a Netgear c6300. I am thinking of switching to linksys like my buddies if this problem persists.

1. Dosnt let me log into netgear genie. I tried loging in with internet and ethernet, just has an infinite loading screen. When i press any of the tabs on the side it still loads.... The only time it works is when i do the button reset on the back, then it goes back to normal the next day. The usual loading screen

 

2. Sometimes when im in a gaming session on my PC it randomly has NO WIFI. I have to go disconnect and reconnect, sometimes even like more than 3 times. it even says "Connected, Secured" most of the time. In other cases it says "No internet"

 

3. I experiance this  A LOT. 

Im just on youtube and the wifi turns off.... Similar to #2 then I wait like 1 minute it turns back on. This is SO RANDOM. the wifi can go away for as little as 20 seconds to like 3 minutes, and then it can come back too like in 5 minutes sometimes in 30 minutes.

 

I RESETTED A LOT! more than i think i needed too

 

I hope this can be fixed, if not i think i may have to sell it
