To compliment your high speed wireless modem router, TP-LINK have launched the Archer T4U, a wireless Dual Band USB adapter that supports both 5 and 2.4Ghz bands plus high speed USB 3.0 connectivity for additional performance.

I had several USB wifi-dongles before in my pc, but none of them delivered the speed what should be the maximum. I tested all of them on speedtest.net but every time the result was around just half of the speed of our connection ( we have 75mbit net, results were around 30-35mbit).

I bought this after my son took a fifty foot network cable and ran it through the house from his computer to my office. This unit was super easy to setup. In less than five minutes I was running speed tests to our Wireless AC router and was getting 128 mbps, which as it happens is what my wired PC...

This is a great AC-class adapter, but the very nature of AC limits its usefulness. If you are in the room with your router, then you will enjoy a very fast connection. As you move further away and put walls between the adapter and the router, the connection speed quickly falls.

Nice appearance if somewhat large; Glossy black finish; Fast AC adapter connects at up to 867 Mbps on the 5 Ghz band; Has USB version 3 connector and included USB3 extension cable; USB v3 is the current standard and should be the default version on all quality networking equipment going forward.

Large adapter could potentially block access to a neighboring USB port on a laptop; it does include an extension cable which could help in this circumstance. The glossy black finish isn't a big deal to me either way but it is a magnet for fingerprints and dust.

The set up of this adapter was very easy. The best thing about set up is the usb cord that is included. This allowed for easier placement and not worrying about having an object sticking out of your usb drive and possible getting damaged.

Installation of the adapter was easy and it works well. We do not have an AC router, so we could not test the higher speeds, but we got full performance through our B/G router. It seems like it will hold up over time. Overall a great product!

Very good for the price,it is a huge upgrade over my old wireless adaptor. Not necessarily my first choice though if i had another chance to buy a wireless adaptor.

-Fast; -5G; -Affordable; -Strong connection

-Sometimes randomly disconnects

The adapter does not automatically link to my WIFI, I have to link it to the network each time before use. Once it links, it is fast.

I wanted to wirelessly connect a Windows Vista pc to router but device does not support Vista. Would not work in compatibility mode either! Ended up buying a Netgear similar device which works with Vista. It pays to research products thoroughly before purchase.

Simple plug and play device.A little on the big side size wise.
