Something to try, on the assumption that your Wireless connection is still active, when you next experience a connection problem on either of your windows computers, try the following which will check to determine if you still have a connection established to your router followed by a second check to see if a direct Internet communication is still possible:-
- Press the Windows Logo keyboard key and the "R" key combination together to open a 'Run' box
- Type (or Copy and paste) the following command text
CMD /K ping 192.168.0.1 -t
- A Command Prompt window will open and commence a continuous communication ping to your router, assuming the 600N default gateway address is actually 192.168.0.1 (according to the manual!)
- If the ping is successfully it will display as
Reply from 192.168.0.1: bytes=32 time=2ms TTL=64
Reply from 192.168.0.1: bytes=32 time=1ms TTL=64
(note bytes/time/ttl numbers may differ but 'Reply' indicates success and a "Request timed out." indicates communication failure)
If that was successful, now to check the Internet communication path:
- Close the 'Command Prompt' window opened previously
- Press the Windows Logo keyboard key and the "R" key combination together to open a 'Run' box
- Type (or Copy and paste) the following command text
CMD /K ping 212.58.244.22
- A Command Prompt window will open and commence a continuous communication ping to the bbc.co.uk web site
- If you see a 'Reply' message as before then the connection to the Internet is working. This would then most likely indicate that the downstream Plusnet Domain Name Servers (DNS) are not responding correctly. If so, the DNS settings can be changed on your computer to use a more reliable service e.g OpenDNS or Google DNS
