TP-Link TL-WDN4800

Dual-band Wireless-n PCI-E card

This PCI Express card adds 802.11a/b/g/n wi-fi connectivity to any modern desktop PC running Windows. It’s a dual-band adapter, meaning it supports connections on both 2.4GHz and 5GHz frequencies.

Setup is easy, requiring only a spare PCI-E slot. If you’ve ever installed something like a graphics card or network adapter, it’s simple. If you’ve never taken the side off a PC case before it may be a little intimidating, but it’s far from brain surgery. Drivers for XP/Vista/7 are included on a CD in the box, and Windows 8 recognised the adapter without the disc.

The TL-WDN4800 has three adjustable-angle antennas, which will end up poking out the back of your PC. If you can position the adapter in your top PCI-E slot, it helps keep cables from knocking those antennas around. Their orientation does have quite an impact on signal strength, so a bit of fiddling around and testing will net you the best possible speed.

The TL-WDN4800’s theoretical maximum speed is 450Mbit/s. In our lab environment, we were able to get consistent transfer speeds up to 149Mbit/s over 5GHz, and 114Mbit/s over 2.4GHz networks. Your results will vary depending on distance, the router or device you’re connecting to, and the environment your wireless network is set up in.

Connections proved very stable, with no unexpected lag or dropouts.

If you’re living in a rental that you’re not allowed to re-wire for Ethernet, or you simply can’t be bothered laying cable throughout your walls, this little adapter is a must-have addition to your desktop PC.

Malwarebytes shoots the breeze with channel, prospects

Malwarebytes shoots the breeze with channel, prospects

A Kumeu, Auckland, winery was the venue for a Malwarebytes event for partner and prospect MSPs - with some straight shooting on the side. The half-day getaway, which featured an archery competition, lunch and wine-tasting aimed at bringing Malwarebytes' local New Zealand and top and prospective MSP partners together to celebrate recent local successes, and discuss the current state of malware in New Zealand. This was also a unique opportunity for local MSPs to learn about how they can get the most out of Malwarebytes' MSP program and offering, as more Kiwi businesses are targeted by malware.
