?FAQ’s on Best PCIe WiFi Cards

Below are a couple of queries on the Best PCIe WiFi Cards that everyone is expecting to answer and I did include the same for my readers.

(Q) Are PCIe WiFi cards better than USB?

You would want to know that both USB and PCI-e wireless adapters are suitable. They come with features that are helpful for you. But, when you use a USB, the strength of the signal and the quicker transmission is slower. 

Not to mention, there is no WiFi connection through the USB connectivity possible. That leaves you with the PCI-e wireless adapter. It not only comes with better reception for your internet requirement, but you can also work even in remote areas too. 

(Q) When using the Ethernet, should the WiFi be turned off? 

When you plan to use the Ethernet on your PC or laptop, then you can turn off the WiFi. There are several reasons. The first one being, the WiFi will drain your battery. When you are based in a remote region, then battery life is crucial for survival. 

When you plan on connecting to the Ethernet, you may want to disable the WiFi. You can make the process automated to avoid breaking your head in the setup process. This can be done in the settings of your laptop. 

(Q) Which is faster: WiFi or Ethernet?

Though WiFi is quick, those of you working on the PC or laptop for a few years, will know it. The Ethernet is faster than the WiFi. However, you can also increase the speed of the Ethernet wired connection that you are using currently in your location. 

You can do that by using a Cat6 cable by more than 10 Gb/s. As you know, the connection is wired, and hence they are quicker. But the kind of cable wire you use can have a significant impact on the speed and locality where you are residing. 

(Q) Are USB WiFi adapters useful and worthy?

Yes, USB WiFi adapters are useful and worthy because they get the job done. However, the USB wireless adapters do not come with any external antennae; the power is lesser. But, many users have felt that the speeds using the USB wireless adapters are good. 

Other factors that depend on the speed include the location of the user and the wireless adapter that is used for the PC or laptop. If you are residing in a remote area, then you might not get high speeds. 

(Q) How to upgrade your WiFi card?

Upgrading your WiFi card need not be a tedious process at all. Those of you with basic knowledge in operating a PC or laptop will know how to do it. Today’s laptops come manufactured with features that adapt to WiFi communication. 

Though the laptop does not come with the latest technology, it can be upgraded with the latest features you want. Not to mention, you can also install the WiFi wireless adapter or use the Express card slot.
