Can't connect through switch
I have a witch that connects to one of the LAN port on the router and until a few days ago all devices on the switch was able to get a valid IP from the router. Now, none of my devices are able to connect. If I connect directly to the router on the LAN port, it works but as soon as I put the switch in and connect through the switch, I can't get a valid IP. I tested the switch and it's working since I have other routers (ASUS & TP-Link) available for testing. I have reset the router but still has the same problem.
Thanks everyone for the reply. I have finally found the issue that was causing the problem. It seems that the Directv Whole-home connector was causing the problem. I had only been debugging the switch and router since all the symptoms were related to them. Not sure what update was pushed, but the problem resolved itself once I removed that from my LAN on the router. It doesn't make sense on why it would cause a problem.
As for all the suggestions made by everyone, I did try all of them prior to posting even with powering each item in sequence (router, switch, computer).

Did you also remove/restore power to the switch?
Basic switches are dumb Switch itself is gone bad or if it uses wall wart, it could've gone bad.

Sometimes "rebooting" the switch can help. Even a basic switch builds and maintains a switching table as it learns which mac addresses can be reached on each switch ports. They have no user interface controls, but that doesn't mean they are dumb.
I don't think this switch has actually failed though, since it did work when the poster connected it to another router.
