I have a router model Zyxel and it is not working with ethernet cable to my windows 7 pc. I tried the cable with my laptop and it is working. I went to a pc shop and connected my pc to their internet through their cable and it is working. The wifi of my router is working, it's just that i could not connect it through ethernet in my pc. I also tried changing the cable but it is still the same. In network connections it shows that it is being identified then it is gone then identifying again then gone again and again. Can someone help me please 'coz i haven't used my pc online for 3 days already !
