So im deployment and we have hardwire internet in my room. wanting to use all other devices eg. iphone and what not i bought a router to plug the hardwire in to and run the wifi off the router for all devices. its made by TP-LINK the model is TL-WR940N. it worked great for a while but then kept giving me DNS server is not responding but i could plug the hard cable in my computer and the internet would work fine? so i reset the router and set it all up again like before. Now i cant get it to run wifi off it anymore it recognizes and connect through wifi but no internet and its telling me i need to plud the hardwire in to my internet but my computer is recognizing it and saying i have internet access, but no internet i mean its not even thinking if there is internet. i have re-set up the router twice and still same thing? im lost on what to do? i run a lot things off my iphone and with no wifi i cant keep in contact with people let alone my wife through certain apps to text or things.. any help would be very grateful thanks?
