IntroductionIn this article, I will cover 5 things you can do to troubleshoot your Windows Vista networking issues; including automated diagnoses, command line tools, and a strong troubleshooting methodology.Windows Vista is no different than any other operating system in that, sooner or later, you will have networking issues. This could be caused by the OS (Vista in this case), misconfiguration by the user or IT Admin, network issues, or other causes. Thus, it is not a question of if you will need to perform Vista network troubleshooting, it is a question of when will you need to perform Vista network troubleshooting. In this article, I will walk you through my 5 tips that I recommend you use to troubleshoot Windows Vista networking issues. Let us start with the first tip. #1: Use the Bottom Up ApproachI recall reading my first Cisco networking book and learning about the 3 different approaches to network troubleshooting (see my article ).

Have Wifi Connection But No Internet

The 3 approaches to network troubleshooting are the bottom/up, top/down, and divide & conquer models. In the case of Vista Network troubleshooting, my #1 tip is to use the “bottom up approach” to network troubleshooting to attempt to solve your network issue prior to going into real “vista OS” troubleshooting. So what is the “bottom up approach”?If you look at the, you will see that it is a layered model that represents all the different parts which make up a network. The “bottom” layer is usually the physical layer. Think of physical layer as the cabling, NIC interfaces, switches, and electric signals that go across the wire.

If you start your troubleshooting at that bottom layer (the physical layer) and move up the OSI model you will go through the Data-Link layer (usually the Ethernet protocol), the Network Layer (usually the IP Network), Transport Layer (TCP), and all the way up to the Application layer (layer 1).My point is to start your troubleshooting by checking for physical connectivity. Here are some questions to ask yourself:. Is my network cable connected?. Do I have a link light on the NIC?. Does Windows see my NIC and see it as connected?. Does the Ethernet switch have power and show a link light?Whether you have a wired or wireless connection, the questions are the same (or similar).

Take for example this Vista Wireless network connection status:Figure 1: Vista Wireless Connection StatusYou want to look at the “media state”. In this case, the media is wireless but the important thing is that it is enabled.

If you are attempting to connect to a wireless network, make sure that you are actually connected to a network. You can click on Connect to a Network to either connect or disconnect from a wireless or dialup network.On a computer with a physical Ethernet connection, you are going to look for the same thing. Take for example this Windows 2008 Server with an Ethernet NIC:Figure 2: Windows 2008 Media StatOn this server, you can see that the Ethernet media on the wired LAN connection is enabled and you can see that the speed is 10.0 Gbps.If you can verify these things, more on up the OSI model until you find the issue. The old network admin joke about the OSI model is that the non-existent 8th layer of the model is the “end user” and that they are many time the issue.Many of these other things will fall into the category of testing various layers of the OSI model but, as with most networking tools, they apply to the testing of the Network & Transport layers which cover TCP/IP. #2: IP AddressingLet us say that you checked your media state and your link light and you have physical network connectivity. Of course, you can also do an IPCONFIG /ALL to check all your IP settings, like this:Figure 5: Results of IPCONFIG /ALLPerhaps you did not receive these settings because your adaptor is not using DHCP.Even if you do have a valid IP address, default gateway, and DNS Servers, you should ping these to ensure that you can really communicate with them.

#3: Windows Vista Diagnose and RepairFortunately for those who do not want to get into troubleshooting, Vista does offer the automatic Diagnose and Repair of network connections. Us IT Adminstrators can also use this as the “shotgun approach” to solving our problem quicker without getting into trying all sorts of things. To use diagnose and repair, just open the Network and Sharing Center and click on Diagnose and Repair.Figure 6: Diagnose and RepairNote:Vista help also calls diagnose and repair “Network Diagnostics”. This tool will go through and check your network connection to identify problems. It will tell you basically what is wrong in the network connection but if you want more detailed information, you can check the Event Viewer. #4: Network Filtering and DiscoveryAs we move on up the OSI model, we get into TCP layer and application layer filtering. Firewalls are used to filter inbound and outbound network connections.

Firewalls could be local on your Vista computer or they could be out on the network, filtering inbound or outbound connections to/from the Internet. Of course if the firewall is out on our LAN that is beyond the scope of this article.

As for firewalls on your local Vista computer, you can even have more than one but the first one (if you installed a 3rd party firewall). However, the first thing that you want to check is the Windows Vista Firewall that is installed and enabled by default.It is unlikely that the Vista Firewall is blocking all network access. It is more likely that it is blocking just certain inbound or outbound network connections for specific applications.

Set Up Wireless Internet Connection

While it is risky on a public shared network to disable your firewall, one of the first things that I usually do when I get to this point is to just turn off the Vista Firewall to see if your problem is resolved. If it is, you can re-enable the Vista Firewall and then troubleshoot it to determine what port you need to allow your network traffic through.To disable or add exceptions for the Windows Firewall, just click on Windows Firewall inside the Network and Sharing Center.

At this point, you can view its status.Figure 7: Checking the Windows FirewallWe can see that the Windows Firewall is enabled and that means that inbound connections that do not have an exception will be blocked. We can see that we should get a notification when a program is blocked.To try disabling the firewall or creating an exception, click Change Settings and you will see this:Figure 8: Changing Windows Firewall SettingsHere you can turn the firewall Off, view/modify exceptions with the Exceptions tab, or look at advanced features.Besides the Windows Firewall, if you are having trouble accessing computers on your local network, you need to check your Network Discovery settings. To do this, go to Network and Sharing Center and scroll down to the Sharing and Discovery section. Check your settings for things like Network Discovery, File Sharing, and others.Figure 9: Sharing and Discovery #5: Use Common Sense Network TroubleshootingWhile I have offered a number of technical troubleshooting tools, one of the things that more often than not is missed, is just using what I call “common sense” when it comes to troubleshooting network issues. Here are some common sense tips:. Did you or someone else change something that could have caused this new networking issue?. Are you even connected to the network?.

Are you assuming that all network connectivity is lost when really it is just one server or application that is not functioning? (its easy to test for this). Check one thing at a time then move on to the next.

Windows Vista Not Connecting To Internet

Do not change 3 things then see if it works or you will never know what resolved your issue (and you may even create more issues with the multiple changes). And if you change one thing that does not fix your issue, change that thing back to where it was before changing something else.ConclusionYou WILL be troubleshooting Vista Networking issues if you use Vista.

It is not a matter of “if” but a matter of “when”. Being able to troubleshoot Vista networking issues quickly happens because you have a solid troubleshooting methodology (similar to the bottom up approach) and because you have practiced or had issues before. I recommend that you keep these 5 Tips to Troubleshoot Windows Vista Networking Issues handy for the next time you have a Vista networking issue.
