If you can’t connect wirelessly to the Internet, this could be a useful checklist:
1) Check task bar Internet icon for connection status, left-
2) Open Network and Sharing Center -
3) Disable firewalls. Try to connect via Ethernet cable.
4) Open router/gateway settings access page to check settings.
5) Use IP diagnostics tool set or contact ISP support.
Internet Connection Fault (Full List)
If you find your Internet connection isn't working:
1) Check your task bar Internet icon. If the sunshine symbol is showing, your PC
is picking up available networks with sufficient signal power but you are not connected.
2) Alternatively, if your router is listed and you seem to have a connection, try another website (e.g. Google, Amazon) to see if it's a problem with the site you're trying to connect to. If still not working...
3) Open Windows "Network and Sharing Center" (Control PanelNetwork and Internet,
4) If your router/home hub doesn't appear in the Windows Network Diagram, go to 5. If it does appear, in theory you're pc and router should be talking to each other, go to 9.
5) If you think they may have somehow changed since you could last connect to the
Internet, check your Wireless Settings (if connecting wirelessly) and Firewall. In
the Network and Sharing Center, click on "Manage Wireless Networks", then double-
6) In the Network and Sharing Center, click on "Change Adapter Settings", right-
7) If the router still doesn't appear, try turning off your firewalls (Control PanelSystem and SecurityWindows FirewallTurn Windows Firewall On/Offunder the Home Network sectionTurn Off Windows Firewall Ok). If you have another firewall, also turn that off. Try to connect again (if can now connect, you will have to change your advanced firewall settings, if not the problem remember to turn them back on again!).
8) If still not working, as a last resort, if you are connecting wirelessly, try connecting to your router using an Ethernet cable (or vice versa). If you can now connect, open your router device access page (see 10), and check that your PC wireless settings (see 5) match the router settings, if they match, try rescanning for a new wireless channel if the option is available in the router WiFi settings.
9) In the Windows Network Diagram, left-
10) Then on the router symbol again, right-
11) If the above doesn't get your connection working. If your PC is talking to your router, it may be a service provider network problem, you can always make some checks using the tools below. Otherwise, best to phone service provider support.
1) Use Adapter Watch / Karens LAN Monitor to get your PC's IP and MAC addresses,
it should also list your router/gateway/home hub IP address. Your router/home gateway/hub
will also be listed as your DNS (Domain Name Server), as the router will then forward
DNS requests to a local ISP (Internet Service Provider) defined DNS somewhere on
their network. DNS: When you enter a website name (URL -
2) Use Ping Easy to ping your router/home gateway using it's IP address. The "sent" row tells you how many ping messages were sent to it, the "received" row says how many responses were received back from this address by your pc, the "lost" row shows how many of the pings received no reply. If all lost, your router is not responding. You can also use Ping Easy to ping any IP address on the internet.
3) Use Ping Plotter to get a list of routes to your usual/major internet sites (e.g. Google, Hotmail, BBC, Amazon etc) while your internet connection is working. Enter the website URL or IP address in the "Address to Trace" box, then click the "Trace" button at the bottom of the window. Ping Plotter should then list the IP addresses of all intermediate routers along the path to the requested site, and their registered DNS names. FileExport to Text File the results and save for future reference. In future, if you can't access the Internet, you can use Ping Plotter or Easy Ping and enter any of the IP addresses you have saved to analyse how the Internet is responding.
