I've been having terrible problems with my modem/router combination (made by Linksys and was purchased about 1 and a half years ago). It appears that lately every day the wifi part will go down, and I need to unplug and plug the modem back in to get the wifi back.  Everything that is hardwired seems to work just fine.  I'm looking at switching routers. I will keep the modem/router combination for use as a modem, but I want a separate router.  I'm looking right now at the Archer c7 and the Archer A9, and would like your thoughts. 

I have the following equipment that hooks to the internet.

5 Smart phones

2 Roku's

2 Laptop computers (one is hard wired)

1 Xbox One

Would either of these routers work for my needs or would you guys suggest a different one? 

I see that the C7 says you can connect up to 50 devices, but the A9 which is Mu-MIMO says it works great for 3 devices.  Funny thing is the C7 is cheaper.  Am I reading that informaiton wrong? 

What are your thoughts on what will work for my situation?
