My Dell i5 laptop is having the above problem. Any suggestion please. On the task bar it says connected to the internet via my router at full strength but when trying to connect to any website it says not connected to the internet. Tried sites such as eBay, Amazon, Facebook etc. to no avail. I have also re-entered my router password and the same problem persists. What is going on? Then the router would appear to disconnect. Running problem solver recovers the internet connection BUT still won't connect to sites and the problem repeats itself.
