When buying a network card, consider speed, interface capability, and overall quality. Match what you already have, and do research on the capabilities of your device and the options available in the market. Connection speed, interface type, and production quality are important factors. Some network cards require cables, so consider the type of cable needed.
There can be many things to consider when buying a network card, but some of the most important things are speed, interface capability, and overall quality, which often have to do with the manufacturer. Cards, also sometimes called network interface cards or simply NICs, allow a computer or server to access and stay connected to a wireless Internet host. In the early days of wireless connectivity, choosing a card was often a very important and generally expensive undertaking that required at least some understanding of the hardware involved. Technology has advanced over the years, but the prevailing concept is basically the same; the biggest difference today is that almost all computers and servers come with cards already installed, usually internally and completely hidden. Therefore, one of the most important considerations in buying wireless cards today is to match what you already have, at least in terms of capabilities and technical specifications. From there, you can choose to upgrade with an eye to speed, security, or ease of access.
Match what you already have
The first thing you should normally consider when buying a network interface card is the type of card your system, be it a laptop, desktop or game console, is already running on. The vast majority of new technologies come with pre-installed network cards. Understanding what you have is key to finding a replacement that works and matches your previous capabilities.
Accessing your card can sometimes be tricky. The user manual will normally state the specifics of the existing card and will usually also provide instructions on how to access it for service or replacement. Talking to a service technician or salesperson can also give you an idea of the appropriate parameters for your particular machine, and many shops will even swap out the physical card for free with the purchase of the card.
Older machines typically don’t have cards pre-installed, meaning you’ll need to purchase one and install it yourself in order to connect. Your specifications are still important, however, as not all cards are suitable for all devices. We recommend that you do some research on the capabilities of your device and the options available in the market. Ideally, you’ll find a card that’s neither too fast nor too slow for your computer’s capabilities, and is compatible with the server you plan to use most frequently. A little research and investigation can make choosing a lot easier, and again, card sellers are often great resources when trying to answer specific questions.
Speed considerations
Connection speed is one of the most important considerations for most consumers. An 802.11g card, which is usually considered the wireless standard, is often preferred because it provides speeds of up to 54 Mbps. An 802.11b adapter is another type of wireless NIC that is becoming less common because it is slower than its 802.11g counterpart . It provides speeds of around 11 Mbps and is therefore more affordable; it may also work better on older machines with slower operating systems generally. An 802.11n is even faster than the g version, giving you even faster download and upload speeds.
Understanding of interfaces
The basic interface of the card is another important consideration. The most common network card interfaces are a PCI, ISA, or PCMCIA card. The type you choose depends largely on your computer and its interface.
A PCI card is inserted into the computer’s PCI slot and runs at high speed. This is usually recommended for the average PC user, but can be more expensive than other options. An ISA card plugs into a computer’s motherboard and is less expensive than a PCI card, but it’s also typically less reliable. PCMCIA cards are used in laptops. They’re placed in a matching slot in your laptop, usually near the power and utility docks.
Production considerations
The overall quality of the board is also usually important, and in most cases this can be at least broadly limited in terms of manufacturing. For novice computer users in particular, choosing a manufacturer that provides technical support with their product can prove beneficial. Some manufacturers provide telephone support for installing the card. You may also want to choose a card that comes with a guarantee in case of failure or damage.
Possible need for cables
In most cases, wireless cards require no cabling or installation other than popping the card into the expected clot. Some network cards, however, are wired with a cable. If this is the case, you’ll need to consider the type of cable you’ll need. Since the card does not typically come with the corresponding cable, you will need to consider connecting your card. For a card that has an RJ-45 connection, for example, you’d use an Ethernet cable. If your card has a BNC connector, use a coaxial cable. These problems are more common with older models or in machines designed primarily for wired Internet access.
