Here are a few FREE tools that I use on a regular basis to fix my computers and home network.
Toolwiz Care is a one click solution that will keep your computer running in top shape and repair many problems automatically.
Windows Doctor us another free tool we use to keep our computers running at their best.
Slim Cleaner is a great program for fixing registry problems and getting rid of junk files on your PC.
Advanced System Care (free version) is a great program for general PC maintenance.
MZ 7 Optimizer is a tweaking tool to get the best performance from windows 7.
RefreshPC is a great program that will reset your computer back to all the default settings used when Windows was first installed. Many networking and other computer problems are caused by changes to windows default services and registry settings. Your software programs will not be changed in any way.
When I have a problem with my computer I run the first four programs listed above in the order in which I have listed them. To solve networking issues you will need to run these programs on each computer on the network. Following this procedure will fix 95% of all windows 7 settings related problems and issues.
This should give all the computers on your network a comprehensive tune up and repair.
After running these programs test to see if your networking problem has been fixed.
If your networking problems still persist try running the Homegroup trouble shooter and Network Trouble shooter from the “troubleshoot problems” option in the “Network and Sharing Centre” control panel.
If your networking problems have not been resolved try temporarily disabling the firewall and see if this fixes the issue. If it does, you need to reset your windows 7 firewall to it’s default values via the firewall section in windows 7 control panel.
If networking problems still persist make sure the following services are running on your Windows 7 computer to use the Homegroup networking feature.
• DNS Client
• Function Discovery Provider Host
• Function Discovery Resource Publication
• Peer Networking Grouping
• HomeGroup Provider
• HomeGroup Listener
• SSDP Discovery
• UPnP Device Host
You can turn on the services by clicking on Start and typing in “services” and then clicking on Services.
In the Services dialog, double-click on the service and make sure the Startup type is set to Automatic and click Start to turn on the service.
Router Supports IPv6
This is pretty much not an issue anymore, but just for the sake of covering all bases, you need to make sure that your router can support IPv6 protocol. If not, Windows 7 cannot communicate with the other computers using HomeGroup. Any relatively new router will support it, so unless you have a really old router, you should be ok.
Run Network troubleshooter
This is to ensure if the connection failure is due to low network signal or no signal.
Using the Network troubleshooter in Windows 7
Try updating your network card driver to what is compatible with Windows 7 so that there is no conflict.
