Windows 10: Ethernet/Wifi doesn't connect to internet on my Dell G15 5530.

I'm facing serious internet connectivity issues and I don't know what to do. I myself being a tech head and able to solve others problems, can't able to solve my own problem.I'm currently staying in my college hostel, where the college provides only Ethernet, no Wi-Fi. Initially, everything worked fine. Whenever I plugged the Ethernet cable directly into my laptop, it connected to the internet automatically without any issues.Since I needed Wi-Fi for other devices, I recently bought a router. We have two Ethernet wall ports here one is now connected to the router, and the other directly to my

WIFI Works, Ethernet won't

Fart

Brandon,

I don't know what I mean. YES ON WIF i can connect to the internet, but you cannot connect to anthing plugged into the same WIFI ROUTER with CAT5 Cable ethernet. My MacBook Pro has WIFI and ehternet, ethernet wont work, but wifi will. My Dell does not have wifi, and I cannot connect to the network or internet at all. As I mentioned, I changed the WIFI Router about a week ago, problem solved, for 3-4 days, now ethernet to the new router does not work again.

 

WIFI Works, Ethernet won't

OK but why?

NOT YELLING, JUST EMPHASIZING

Please note, I installed the new Lynksis, it worked just fine for 3-4 days on both my MACBOOK PRO when in ethernet connect and the Dell, then the ethernet just quit working for both my MacBook Pro and Dell desktop. It did work, then just quit for no apparent reason. WIFi for iPhone, iPad, Andriod Phone, and when I set to wifi for my MacBook pro all work fine.

Detailed history: I first noticed that on my Desktop dell that is CAT5 ethernet connected to the WIFI ROuter, that it stopped, no internet access. I began to trouble shoot, and turned off my WIFI on my MAcbook and it wouldnt work either, plugged into same router but different cat5 cable. At that time, all WIFI devices still worked. I figured that it must be the ethernet side of the WIFI router, so I replaced the router with brand new one. the Lynksys N900 listed in original thread. Ethernet and everything worked just fine for 3-4 days. But then ethernet quit, but wifi still works.

Whatever the problem, it affects both my MacBook Pro and Dell with WIN 7. I'm guessing it is NOT a computer problem, if it is it is affecting both my Mac and Dell, separate cat 5 cables to same wifi router

To remixedcat, I don't know for sure how to check IP settings, see above post, no damage apparent to anything.
