This isn't the exact same model as my wireless network card, but it is by the same manufacturer and has the same set of features. Mine is the WN350GD model.
To start with, the most common reason why you want one of these wireless network cards, is to get rid of all those ethernet cables you have trailing from your PC to your router, correct? Well obviously this can take care of that problem.
I'm going to go a bit technical now, but I'll try and explain everything i say so everyone can understand.
This wireless network card can transmit data at a speed of around 7 Megabytes per second (54MBPS) Remember a byte is 8 bits, so 54MBPS (MegaBITS per second) is = to around 7 MegaBYTES per second, i don't know why everyone uses Megabits instead of bytes in the world of wireless networking, but I'm sure they have a good reason for messing with our minds. Very few internet service providers (that's people like BT, Virgin, Talk Talk or whatever they call themselves now) supply speeds greater than 40MBPS, so this card shouldn't affect your internet download speeds.
The only differences between using this wireless network card and an ethernet cable, is that wireless network cards are affected by their environment, such as going through walls may lower the signal strength, and thus lower the speed at which it can transmit. Also ethernet cables usually transmit at a speed of 100MBPS, sometimes 1000MBPS (or a Gigabit per second). This would only affect you if you wanted to transfer large amounts of files across from one PC to another on the network. (We're talking several Gibabytes of information to make it worth talking about)
I hope i explained that well enough to everyone! The basic gist of it is, this card is fast enough to work in most homes without any noticeable slowdown compared to using a cable.
Security wise. Now security is a thing we're all concerned about nowadays, with all this technology, it's all too easy to lose your security. This wireless network card however, supports all the latest security encryption, such as WEP, WPA and WPA2. These are basically passwords for your network, you set up the password in your router, and then when you want to connect your PC to the router (through which you connect to the internet) you enter the password. We will go through that now.
This product should come with a little mini-disc and a set of instructions, read the instructions and follow them. I don't believe the instructions tell you how to connect to your wireless router, so I'll cover that for them.
TP-LINK wireless client utility should have installed itself on your system if you followed the instructions correctly. If you have it in the list of programs in your Start Menu, boot it up now.
Navigate to the 'Profile Management' tab. Click on the 'Scan' button. Select your wireless network from the list, hopefully its there. Type in a profile name, just something that will tell you what network you are on. Now navigate to the 'Security' tab. On your router setup, you should have selected a security encryption and password, select the correct encryption type and enter your password in the box supplied. Thats it, your done, the next tab should already be setup the way most people would have it, so just click the OK button, and if all goes well, you should connec to your network and, hopefully, have internet access.
That mini-disc i mentioned earlier has the drivers for most TP-LINK wireless network cards, and the wireless client utility is also compatible with all of them.
I have had intermittent problems with my card, were the signal drops to 1/4 strength and then picks up to 3/4 or 4/4 a couple of seconds later, not sure why, but i believe it is to do with the positioning my computer, also the motherboard isn't in perfect condition, so it's possible my PCI slot is damaged. I have 2 PC's with these cards in, and 1 works perfectly, and rarely drops below full signal strength. This is definitely a card to buy if your on a budget. They tend to sell at around £5-7.
Having just picked up this new adapter I 'm happy to say that it has so far exceeded my expectations. I live in the Uk in a Victorian flat, our walls are very very thick. My previous Belkinb card I had for about a year. I had numerous problems with it over the time it was instaled and eventually got so frustrated that I drilled a hole through the wall and ran a wire through instead. The entire experience was rather frustrating.
This card was the only one available in my local pc repair shop and cost a nice £19.99.
It was a doddle to install into the pc and the disc worked without any issues.
So far over the past 3 days I have had no disconnects at all, on the Belking I was getting a few every hour. I am so far very impressed with the adaptor and highly recommend it as a good investment
