MIMO technology with stronger signal penetration strength, wider wireless coverage, providing better performance and stability

Easily setup a highly secured wireless link with QSS (Quick Security Setup)

Includes a low profile bracket

Wireless N - Speed & Range

MIMO (multiple input, multiple output antennas) technology, it shows more excellent abilities of mitigating data loss over long distances and through obstacles in a small office or a large apartment, even in a steel-and-concrete building. Above all, you could easily pick up the wireless network during long-distance connection where legacy 11 g products may not.

CCA Technology - Stable Wireless Signals

Clear Channel Assessment (CCA) automatically avoids channel conflicts using its clear channel selection feature and fully realises the advantages of channel binding, greatly enhanced the wireless performance.

WPA / WPA2 Encryptions - Advanced Security

As for the security of WI-FI connection, WEP encryption has been no longer the strongest and safest guards for outside intrusions.

Not only is this faster than normal security setups but more convenient in that you don't need to remember a password.

Works smoothly, but gets rough with windows 10.

Reviewed in the United Kingdom on 30 June 2017

Style Name: Wireless 300 MbpsVerified Purchase

Totally adequate wifi card for windows 7 or earlier, till I installed windows 10 it didn't have any problems, besides causing a bug that jerked the input focus around like a ragdoll if you closed the window which lists networks. When installing windows 10 you should remove the damn thing because otherwise you'll get errors you've never seen in your life. Why 4 stars when it has such glaring defects? Because it's the cheapest 300mbps card that amazon uk has to offer with the free delivery deal. If you want internet for a desktop running windows 7 or earlier this is the absolute best value for money card on the market.

maybe i was unlucky

Reviewed in the United Kingdom on 4 January 2020

Style Name: Wireless 300 MbpsVerified Purchase

maybe i just had bad luck ?
first off, the drivers on the driver disk do not work. Tried both on W7 and W10.
I then got the drivers from the official website and they managed to install, but then stopped working with a corrupted driver.
I did a driver sweep and re-installed, and it worked for a couple days, and then the whole rig wouldn't boot with this in it.
really needing internet, i did a re-install, and dropped this ting in first thing, with the official driver from the vendor website (imagine getting stuff from the itnernet WITHOUT internet - oh that was fun), only to have a catastrophic system crash not 24h after that.

Please know that THE SAME SYSTEM (with a brand enw W10 install, but otherwise the same hardware - same mobo, same RAM, same SSDs is still happily running now that i have a different brand, same price wifi card also here form Amazon. so ...

Windows 10 automatically recognised this card, and installed a driver.
The machine then completely locks up, even the mouse.
If you disable the wifi, the machine will stay running long enough to install a working driver.
Had to manually 'force' an install of the driver from TPLink site for win8 64bit.
This was no easy task.
But, I am expecting a windows update to decide it has a 'better' driver, at some point in the future, and break my machine again.
ps Under linux (ubuntu Mate) it just works perfectly out-of-the-box.
Getting very hard to find any cheap PCI cards that have working drivers under windows 10.

Excellent value - fixed my onboard LAN adapter issues

Reviewed in the United Kingdom on 31 August 2017

Style Name: Wired GigabitVerified Purchase

Bought this resolve issues with the on-board LAN socket (Atheros L1 Gigabit Attansic) on my 9 year old motherboard which was regularly dropping my internet connection with "Default Gateway Not Available" messages and also could not cope with file transfer demands between my new Netgear (Gigabit) router and Synology NAS on Windows 7. As soon as I attempted to transfer any large files to or from my network drive, my whole PC would just freeze and hang, requiring a hard reboot.

I bought this particular TP-link NIC card as I specifically wanted to use one of the available PCI slots on my motherboard as my only other PCI-E slot was taken by another expansion card (USB 3.0 card). It was a breeze to fit. Initially was not picked by the BIOS and the PC failed to POST. However probably my own fault as I tried to boot it without doing a CMOS battery reset and clearing the RTC Ram. After I did those things, the PC booted fine. I disabled the on-board LAN adapter via the BIOS and when Windows 7 started the TP-Link card was already recognised and installed in device manager, I did not need to use the included drivers from the mini-CD.

I am now getting reliable smooth 1Gb transfer speeds my NAS and PC and general internet works as good as ever without constantly being disconnected. So this card is highly recommended.

All in all a great fix to my problem for £7 and has breathed new life into my aging PC.

Inconsistent Performance

Reviewed in the United Kingdom on 17 August 2017

Style Name: Wireless 300 MbpsVerified Purchase

I purchased this because my large desktop PC had a tiny USB wireless button aerial and I thought this high-performing card would be far more stable. (The USB wireless-N occasionally required re-plugging to establish contact, though this was rare.) The opposite turned out to be true - the TP-Link Wireless N card had poor or erratic signal and often lost contact with the router (only some 14m away). The card or its software driver would often 'go to sleep' and not wake up when required, or simply drop the connection when no other factors had altered. In the end, and with some disappointment, I replaced the tiny USB wireless plug-in and instantly achieved more stable connections, so I wouldn't recommend this card especially as the USB solution is also cheaper.

Okay for the money

Reviewed in the United Kingdom on 6 October 2018

Style Name: Wireless 300 MbpsVerified Purchase

Its cheap, but I would compare this to using mobile broadband, it cuts out so often and the signal is weak, in fact from twice the distance my mobile still does a better job getting full WiFi signal whereas this gets one bar and struggles, my WiFi router is in the very next room with thin walls. My PS4 Pro is 2 floors up and 3 rooms across and gets full bars. But it costs next to nothing. So its okay while I rebuild my PC. I need to update my motherboard with an express slot anyway. Maybe its the Win 10 issue, though I've had no errors or driver issues the cutouts are a pain when you want to use the internet for banking etc. It can take 10 mins even just to check my balance.
