These are the things you would have to check and set
1 check the wifi security protocol that you are using. eg is it wep, wpa, wpa2? which.
2. from 1 above ensure that you set it correctly/correspondingly/accordingly with the correct password / passpharase (Capitals matter)
3. look at your wifi indicator, what icon / symbol does it show? does it have an ! exclamation mark still? If yes, this means that you ARE connected with the router but have either the wifi security password WRONG or that your OS does not have the right wifi security which is used by the router. Check the other machines that can connect successfully

4. try to set your ipaddress manually. Since your router is 192.168.0.1 then input manually this ip address 192.168.0.3 with the subnetmask of 255.255.255.0

5. try to list out for us here some screen shots of how the problem looks like, this would attract other experts to help you.

Meanwhile do an ipconfig /all and copy it for us here to help you diagnose further.

Good luck

PS in your testing, stick to one adapter which is (not the bufullo one) and as you mentioned there are error messages... copy them here for us to see

In case you dont understand, your computer should be getting automatically assigned (called DHCP) ip address by your wifi.router. It does this only when your computer's tcpip settings show


Note below: Where to check the wifi security protocol of your computer and ensure that you have chosen the right one your router is using *and where your password should be stored
