We have bought the above so that we can get a connection when visiting an elderly relative who doesn't have broadband. I have changed the default passwords and everything has worked well for months. It connects to the 3 network. Recently we have had a good connection to the modem but the dreaded yellow exclamation mark appears in the wireless icon to say that there is no internet connection. The laptop has a correct IP address via DHCP. Can you remind me of the troubleshooting steps to take please. There is no channel conflict as there are no networks nearby with anything like a strong signal and we have put the modem right next to the laptop. The one thing that does work (sometimes) is the Windows troubleshooter which disables everything and then re-connects. I'd like to find out what the problem is rather than the 'switch off and on again' route.
