Repairing a Malfunctioning WiFi Switch As the vast majority of laptops now are wireless-ready, they come equipped with a wifi switch. This switch controls the computer’s ability to access a wifi network. It does so by either activating or inactivating the wifi card. Very occasionally, laptop owners will experience recurring internet problems (e.g. can’t access the internet if not hooked up to an Ethernet cable) that aren’t resolved via normal internet connection troubleshooting. In these cases, there is a possibility the true problem lies in a defective switch or a defective wifi card. Of course before you begin to suspect the switch, make sure you go through all of the normal connectivity troubleshooting steps. Ensure your firewall isn’t blocking access that your service isn’t out, etc. If after performing all of these checks there still exists a problem, investigate the viability of the switch or wifi card.

There are a couple of different ways to address your dell laptop wifi switch problem. It should be noted, however, that they involve disassembling the laptop. So, if you aren’t proficient with computer repair you may be best suited to have the laptop fixed by a professional. The costs of repairing (for example) a Dell laptop wifi switch may be less than you’d expect. Should you decide to go the home repair route, it will most likely require you to completely take apart the computer. You can order the appropriate switch/button part needed from a computer repair shop and replace it internally. If upon testing, it is found the wifi still doesn’t work, then you might want to investigate the integrity of your wifi card. New cards vary in price; you can expect to pay anywhere from $40 to over $100, depending on the type of card you purchase. The cards are generally not exceedingly difficult to install. Replacing the switch or the card should generally be a solution to a wifi problem that isn’t due to other connectivity issues.
