Sorry to post about another tech issue, but I haven't been able to connect to the internet on my PC for the last few days. My router shows up under the available networks at first, but after the initial attempt to connect (and the "Cannot connect to this network" message) it says "No networks found" and won't let me try again. I can get the router to appear again by running the diagnostic tool, but I still can't connect, and the tool concludes that I haven't actually attempted to. Other devices in the house can connect with no problems. Is there anything else I should be trying? Thanks!
Do you connect via LAN or WAN? If LAN, make sure the network card drivers are up to date. If WAN, the wireless adapter drivers.
If they all show as fine then go to Control Panel, Network and Internet, Network Connections (you haven't stated what OS so I'm assuming Win7). In here right click on the relevant LAN connection and select 'Diagnose'. It'll try to automatically find out what's wrong and fix it.
If this doesn't fix it. Go to Start and type 'cmd' into the search box and press enter. In this box type 'ipconfig /all'. It'll show a number of different adapters depending on what you've got hardware-wise. Look for the relevant connection (LAN or WAN) and see what the IPv4 address is. It should be something like 192.168.0.5. If it starts with 169.254.x.x then this has been self-assigned because it can't get an IP address from your default gateway (router). Take a note of the default gateway address (it'll be on the same subnet so something like 192.168.0.1) and try to ping it from the cmd window:
'ping 192.168.0.1'
If you can ping that then you can see the router. If not and all other devices are working, it's possible it's not able to assign it an IP address via DHCP. At this point it may be worth trying to set a static address in the Control Panel.
Go to Control Panel, Network and Sharing Center, then Change adapter settings. Right click on your desired connection, then click on Properties. Select 'Internet Protocol Version 4' and click Properties.
It should have 'Obtain an IP address automatically' selected here. If so, change it to 'Use the following IP address' and choose something on the same subnet as your default gateway. So if your default gateway is 192.168.0.1/24 (Subnet mask: 255.255.255.0) then you can use anything from 192.168.0.2 - 192.168.0.254. I'd pick something like: 192.168.0.50. Obviously change the default gateway and subnet mask to what is listed in your ipconfig.
You can try those settings like that, but if it still doesn't work, perhaps try using Google's DNS servers if you don't mind Gaywood backdooring into your computer and looking at all your photos:
8.8.8.8
8.8.4.4
That'll do for now, I guess. If none of that works then throw your computer in the bin and buy a Mac.
