To improve network card speed, upgrade to an up-to-date adapter, ensure hardware is upgraded to the same level, and check that software like firewalls aren’t limiting speed.
To get the best possible network card speed, you should consider the type of network card you have and how you connect to the network. Your adapter may be an older model, and you may be able to increase the speed simply by upgrading the hardware. It’s also possible that the router you’re using isn’t taking full advantage of your network card or other hardware, so you should be sure you’re upgrading all hardware sufficiently. Since network card speed can also be affected by the software you use, you should also make sure that your speed isn’t limited by a firewall or even other limitations on your computer.
The speed of the network adapter can be affected by a number of factors, many of which may depend on how the adapter is configured on a computer. One of the first things you should consider is the adapter you’re using; make sure you have an up-to-date model. If you’re using a wireless adapter, for example, you should make sure it’s not an old adapter that runs at a slower speed based on older technology. A wired adapter typically uses an Ethernet connection, and you should be sure you’re using an adapter with the highest possible transfer rate.
You should also make sure that the networking hardware you’re using, such as a router, isn’t negatively impacting the speed of your network card. If you have a wired network card that uses 1,000 megabit (Mb) Ethernet, for example, you should make sure your router is also 1,000 Mb and not at a lower speed like 100 Mb. Similarly, if you have a Wireless N network card, it will be backwards compatible with older routers that use Wireless G technology, but such hardware will not take advantage of the network card’s speed improvements in Wireless N protocols. You should be sure all your hardware is properly upgraded to the same level.
Your computer hardware and software can also negatively impact the speed of your network card. If you’re using a firewall, for example, you should make sure the appropriate ports are open or forwarded for the websites or online services you’re using. Your computer hardware can also reduce the effective speed of your network card. Although the actual adapter may be quite fast, if you do not have enough processing power or memory in your computer, the received data may still be displayed slowly, resulting in a slower speed of the network adapter.
