Reset Your Broadband Modem and Router Your broadband modem’s connection to the Internet will occasionally become unreliable, and restarting it can fix that. The same trick also occasionally works for the connection between a router and a broadband modem. To reset your broadband modem and router, disconnect their power cables and leave the modem and router off for 30 seconds. Next, reconnect the modem’s power cable to restore its power.
Wait a few moments for the modem to renegotiate its connection to the Internet and establish a solid link; then plug in the router. You should then be good to go. Configure Wireless Security The vast majority of wireless broadband routers available today ship with their wireless security features disabled. This makes it easy for novice users to set up a wireless network in their homes or offices, but it also leaves your network vulnerable to prying eyes.
Although the exact procedure necessary to enable wireless security will vary from router to router, in general the steps required to access the pertinent options will be similar. To prevent unwanted users from accessing your wireless network, be sure to enable some sort of Wi-Fi security. Click on the Wireless tab or Wireless Security tab.
If you have relatively current wireless devices that support the standard, we recommend enabling WPA2 Personal on your home network because it offers stronger encryption that other methods.
Save the settings and reboot the router; at least a basic level of Wi-Fi security should now be in place. Open and Forward Ports Some applications require that certain network ports be opened and forwarded to the correct PC for some of their functions to operate across the Web.
Game servers are a great example: As always, though the exact process necessary to forward ports will vary, the steps required to access the pertinent options within any router will be similar. Check out our guide to port forwarding for more information. For example, if the machine running the application you are troubleshooting has an IP address of Save the settings to enable the rule, then reboot the router to finish the job.
In those cases, the machine can be placed in a network DMZ, or demilitarized zone. Putting a system in a DMZ allows all of its ports to be accessed from the Internet. Let’s assume that your router IP address is indeed Open a Web browser and type Enter the IP address, save the settings, and reboot the router; that system should now be in the DMZ. Those drivers tell the operating system how to use a device and occasionally need to be updated to resolve issues or add new features and capabilities.
Updating network drivers in Windows is usually done in one of three ways: When possible, use the first method: Updating a driver through Windows Update is easy and automatic. Unfortunately, manually installing a driver through Device Manager is a bit more complex. To do so, click on the Start button and type Device Manager in the search field.
Press Enter to open the Device Mananger, find Network Adapters in the list of devices in the system, right-click on your network controller, and select Update Driver Software from the menu. In the new window that opens, click on the Browse my computer for driver software button; then click on the Browse button and navigate to the folder where you placed the newer driver you downloaded.
Click the Next button, and the driver should install automatically. Disable or Add Exclusions to Windows Firewall Windows 7’s built-in firewall constantly asks you to allow or deny an application’s access to your network.
If you’ve mistakenly blocked an application and want to unblock it or the other way around you’ll have to manually change some settings in the Windows Firewall control panel.
Click on your Start button, type Allowed Applications in to the search field, and press Enter. In the resulting window, all of the applications installed on the system that were flagged by Windows Firewall will be listed.
Conversely, if you’d like to allow a program that was previously blocked, find it on the list, and select the appropriate boxes next to the entry. Scan Your Network for Attached Devices With so many connected devices now on the market, there may come a time when you want to scan your entire network to see exactly what devices have obtained IP addresses and are consuming resources. Your router may be able to check the status of connected clients, or you could use a third-party application that will more comprehensively scan an entire range of IP addresses to find and obtain information on the connected devices.
Angry IP Scanner will scan a network and identify all of the IP addresses in use within a given range. Right-clicking on an active device in the list will reveal more details; it will also allow you to ping the IP address and connect through a Web browser or FTP client. Diagnose Internet Connection Issues Finally, one problem that may be beyond your immediate network: Is your Internet connection unstable–and you can’t figure out why?
A couple of utilities built into Windows 7 may help. Ping and tracert traceroute can help you find out if your Internet issues are with your home network or with your ISP–or somewhere in between. The ping tool can be used to continually ping an IP address to check for connectivity problems.
Performing a continuous ping on a known good website we like to use google. Your system will then start continually pinging the Google website. If the connection is stable and reliable, you shouldn’t see any errors, just replies from the IP address with ping times and other data.
If, however, if the connection between your PC and Google is broken for whatever reason, ping will report that there was no response from the server. Tracert is another useful tool that will list the route and measure transit delays of packets across a network. To use Tracert, open a Command Prompt window and type tracert google. This will essentially map out the path from your PC to a Google server, listing the IP addresses of the servers and switches in between.
Usually your packet’s first few hops will start in your home network, then go through your ISP’s network, and then eventually find their way to google.
If the packet doesn’t make it out of your network, the problem is inside your network; if it doesn’t get past your ISP’s network hubs, your ISP probably has a network outage or equipment failure yes, a busted Internet connection isn’t always your fault.
