This network troubleshooting tool can also help to identify routing issues when you have more than one network connectivity. If this repairs the connection, you can narrow down your search by re-enabling the software and going through some of the settings. Check specifically for firewall or traffic blocking settings, try disabling them or lowering the security level. If disabling the software altogether has no effect, continue to the next section. Malware : check for malicious network layer software Windows.
Equally common though these days perhaps more common to friendly firewall software are malicious forms of malware: viruses, or spyware, which either block or re-direct your network traffic. Anything malicious of this nature can be interfering with your network interface and cause all sorts of problems. Contact the Technology Service Desk for help removing malware.
If the machine comes up clean, or the removal of malware did not put the network connection back into a working state, it is possible that the registry still has remaining corruptions due to present or previous malicious software. WinSockFix is an incredibly useful tool that deserves a special mention here because it specifically locates network-related registry entries and attempts to fix them. WinSockFix is available from Softpedia here.
Network Equipment : check local network equipment for problems. The problem can often lie in the switch, router, or modem that your system is connected to. If you have access to this hardware, here are common things to check to ensure that the network equipment is functioning properly. If you are confident that your software configuration is in check and have tried resetting the network equipment, its always possible that the external uplink is having issues.
Try contacting the nearest network administrator if this is a business or commercial setting, or the service provider in a residential setting. Device Drivers : re-install network device drivers Windows. At this point we have ruled out most of the common software issues that you are likely to ever see. Its possible now that either the hardware itself is broken or the driver has been messed up in some manner.
The best way to resolve this is to download the latest official driver from the manufacturer and install it. Hardware : reseat or replace network card hardware. It's always possible that the hardware itself on the network card is faulty. This is especially likely if the problem presents itself seemingly randomly or intermittently.
The first thing to try is simply re-seating the card. This is obviously much easier on a desktop computer than a laptop but the same idea applies to both. This guide will not go into too much depth on the hardware side of things. If you can get access to the card, either by removing the side case of a desktop or the top case of a laptop, try pulling out the card from its slot completely and then plugging it back in firmly.
If there are screws, make sure that they are secured tightly and that the card does not move at all if you wiggle it gently. Still having problems? Contact the Technology Service Desk for assistance.

Question How can I diagnose my internet connectivity problems? Solution Diagnosing a failing Internet connection can be fairly complicated. Web, which will run a virus scan based on the company's database of known viruses and malware. You can also send a download link to the Dr.
Web service , which will scan the download for known malware. Verdict: While it's not a replacement for a dedicated security suite , Dr. Web's online file checker gives you an extra layer of security , allowing you to check files being shared or linked to you before clicking on the download.

Jotti is an online service that allows you to scan a file for viruses and malware. What makes it different is that instead of using just one antivirus scanner , it sends them out to several different antivirus companies and then tells you whether or not any of the companies classified the file infected.
While there is a 25 MB file limit and uploading the file and waiting for it to process might take a bit more time than a single dedicated scanner, Jotti is an interesting way to get second, third, and futher opinions about a particular file.
Got your hands on a new piece of software that your AV says is malware? Check it out with Jotti. As a bonus, anything uploaded to Jotti is shared with the security community so every infected file or false positive you upload helps refine some of the most popular antivirus tools out there.
