I have an update.
Good news: WiFi works
Bad news: Can no longer connect via ethernet...
I found an old router(D-Link) and connected it up and wifi came up, but I didnt know the password for the router page or for the wifi, but that didnt matter because I am not going to use this D-Link router.
Therefore, I went to exchange my router for a new one (still netgear, but different model N600). Connected it all up, wifi works but somehow my computer isn't connected to the network. Sometimes it manages to connect and shows it as a unidentified network. I tried going on 192.168.0.1 from there, but my browser says unable to connect. Sometimes it goes off and no network is identified and a red cross is shown on the network symbol. I tried ethernet through my laptop, but same result as computer
Determined to get internet up for the day, I decided to set the router up using my smartphone. Now I have Wifi over all my devices except my computer
What do you think? Problem with my computer?
