Wireless Card For Laptop

Where to get a wireless card for laptop and what is the best choice for your laptop?

There are many kinds of wireless cards. All new laptops have already built-in WiFi cards. If your build-in WiFi card is not good enough – the connection is too slow or range is too low or some other reason, there are many of wireless cards with affordable prices on the market.

Wireless cards for laptop can be:

1) WiFi cards or wireless cards working on 802.11 standards (802.11a, 802.11b, 802.11g, and

2) Cellular or mobile networks.

With WiFi cards you are connecting to the wireless access points or WiFi routers in the public hot spot or in your home wireless network on your own wireless router.

The advantage of Cellular wireless cards is that you can use them as long as you are within a range of cellular or mobile network operator, but the problem is the speed which is usually much lower with them comparing to WiFi cards.

Wifi Working On Speed Of 1 Gigabit - IEEE 802.11ac

There is a plan with new WiFi standard called 802.11ac which will enable much higher speed in wireless networks. When we talk about the speeds in wireless network they are usually hypothetical, because it is always stated maximum speed. The real speeds depend on the many factors like range and interference. 

The latest WiFi technology which are we using is 802.11n and it has maximum speeds between 150 Mbps and 600 Mbps – depending on the number of antennas that access point or wireless router is using. The 802.11ac will have much greater speed from 433 Mbps to 1.3 Gbps. So there is a first WiFi signal working with gigabit speeds.

There is also a new feature which enables more reliable coverage in indoor places and it offers lower power consumption for clients, because with greater speeds you transfer data in less time. The difference is also in frequency on which it is working.

The new frequency band is 5GHz and this means that all devices will need to make the shift to this new frequency band. And this incompatibility with the old wireless standards which are working on the 2.4 GHz frequency spectrum is the greatest disadvantage of this new technology.

Linksys wireless router

The Linksys wireless router is one of the most reliable wireless routers on the marker. It is widely used because it is very easy to set them up, they are very user friendly and compatible with other systems. 

Cisco is the most trusted brand in networking, so the Linksys wireless routers as the part of the Cisco portfolio are the top quality wireless routers. Linksys has launched the E series Linksys routers. They all come with Cisco connect software – which you can use to manage very easy the settings on the device. You could also enter in the web user interface and configure wireless settings manually by yourself.

There are complains from some customer that they cannot access the Linksys management admin panel after a failed firmware update. So be very careful, if you are doing the firmware upgrade. Only use tested and proofed firmwares which are supported by your device.

It is good to have a hardware stateful firewall, but usually for home and small office users, the Linksys router and firewall in one box is all you need.

You have ability to set up different priorities for different kind of traffic that pass through the router. You can give higher priority to your mails than to your http traffic. This function is called quality of service or QoS.

My advice is that the first thing you change on the Linksys router is a username and password. There are many routers which are running and they still have default username and password. It is very easy to log in to these devices and to abuse them.

Also set configuration view to manual in order to see or change the SSID of your wireless network. After that click on the wireless security menu option, set the security mode and on passphrase on the key entry type the password which will be active on your network. This password is case sensitive.
