has worked for the last year but now when i try to connect to the internet i am told that i am not connected and please run connectivity check. this i do then asked to check leads switch of router then reconnect, continue with connectivity check. eventually i have the message that i have successfully been reconnected. this now happens everytime i swtch on the computer.
obviously a faulty setting somewhere. any ideas will be very welcome. device manager ok.
Have you tried resetting the router? All routers have a reset button - usually one you can depress with the end of a paperclip or similar object. You have to keep it depressed for up to 30 seconds.
