Trouble connecting to Fios router

I am having problems connecting to the Verizon fios router in my house. The first time I connected to it fine after entering the password. My computer went to hibernate during the night and when I turned it back on, it just can't connect to the network. It sees it and even connects to it for a few seconds, but then it just keeps trying to look for another network.

I restarted the router, and it worked fine again. But when it turned off and I tried to use it again later, the same problem came up. I tried troubleshooting but nothing seems to help. Does anybody know a way to remedy this?

PS: The router (which is one of the best models they have) is used by everyone else in the house (8 people and their devices). Is it possible that theres just too much load on the router? If so, can I connect another router to the Fios one and create a usable network off of that? Sorry for all the questions and thanks.

 

You can either double NAT, although I'm not a big fan of that. Or you can also turn the FiOS router into a bridge. I have done it before on my ActionTec. Although I heard Westell is better. That said, I still not believe those router can deliver high performance and high traffic. I have seen the ActionTec slow down to a crawl on a very heavy load of traffic even if it's just a lowest tier 25/5M. If your internet come in as an ethernet then you can just replace the router, there n need for that FiOS router to be there at all. I'm in the process of looking for a new router also, but no one has answered me and give a good recommendation yet.
