Hello,

My wifi router which is connected via an ethernet cable to our downstairs modem provided by Ziggo will stop working after about 1 hour or so.

Whenever I try to reset my router, the router will work correctly without any issues for about 2 days, however, after that period of time, the router can do 2 things:
- It can turn off, no lamps will be turned on and I have to start the router 
- It will provide no connection whatsoever, not via a wired correction nor a wireless connection.

What will work, is restarting the router then after the error occurred, the router will now work for about 1 hour and then the error will occur again and so forth. 

My router is set up as an access point because I want to have a good connection upstairs on the 3rd floor.

The modem downstairs will work correctly even though there is an error on the C2300 router.

What I've tried:
 

- Turning off DHCP (no result whatsoever)
- Turning off 5ghz
- Setting the router as a router operation mode instead of an access point
- Checking the Ethernet cable (it provides stable internet)
- Checking the power cable (it provides stable power)

What I have just noticed is that in the title of the control panel of my wifi router, it says AC2300 MU-MIMO instead of my C2300 router.
