Troubleshooting sometimes can be such an agony, but there are guidelines that we have to follow in order to resolve some issues. Although it can be tedious at times to troubleshoot, you’ll be surprised that other things can be resolved quickly and some will take a little while and you need to be very patient. I have compiled some quick, easy and basic troubleshooting tips that might save you some time going through a very long process of fiddling with settings from your broadband devices (modem/router) and computers.
If you are having an intermittent internet disconnection on all of your wired and wireless devices please see the following suggestions:
A simple Power Cycle will often correct the problem to refresh the network electronic devices and reinitialize their configuration and also help to recover from a hang or crash state.
Run the Network Troubleshooter tool from your Windows 7 computer.
Run the Diagnose and Repair tool from your Windows Vista computer.
Disable/Re-enable the network adapter from Device Manager.
Update the network adapter’s driver from Device Manager
If you are having an intermittent internet disconnection on all of your wireless devices please see the following suggestions:
Interference can cause wireless disconnection issues, this is due to having electronics and small appliances nearby. Neighbors that are using the same wireless channel similar to yours may also cause some conflicts.
Changing the Wireless Channel to 1, 6 or 11 might help. This will require an access to your router setting so you must have your router’s logon credentials.
Before changing the wireless channel, you may install and run Xirrus Wi-Fi Inspector to see the opposing wireless channels.
Any third wireless utility software may conflict with the Windows native wireless utility called WLAN AutoConfig, you must only use one to avoid wireless disconnection issue.
Security or Firewall Software such as Norton, McAfee, Webroot etc. might be intervening, disabling it my help. If it didn’t correct the issue, remove the software by using the proper method of uninstalling it – some do have a removal tool that you may download online, reinstall the software back if the issue has been resolved.
In some circumstances updating the router’s firmware to the latest often resolves this issue if all your wired and wireless network devices are acting up.
If you have a Workgroup or HomeGroup setup in your home network and all or some computers are having intermittent issue accessing the shared files/folders, your Security or Firewall Software might be intervening. Allowing ports or files/printer sharing in the safe zone or disabling the firewall feature might help.
