3 out of 5 eggsWorked like a charm for 5/6 months.

Pros: 2.4 and 5ghz connections, very durable, sleek look.

Cons: Connection drops every 5 seconds. I've had the adapter for a good 5/6 months, there used to be no problems at all. I have a netgear router aswell so I connect via the WPS function, and the connection still drops (which is should not).

Other Thoughts: Unless you have a spare $60 laying around, not worth the investment.

5 out of 5 eggsSmooth connection

Pros: Works well for online games such as World of Warcraft, League, Runescape, etc.

I'm able to do high rated arenas + raids in WoW without lagging or disrupted connections

Easy to install + high quality

Cons: Cord is a bit long

Can't run multiple internet connections at once (via computer + adapter).. you have to disable one to run the other.

Other Thoughts: Worth the price... much better than having to replace my laptop's internal adapter.

1 out of 5 eggsBSODs

Pros: None

Cons: Causes BSODs
So called drivers included with Win7
Manually stripped drivers from win7, installed Netgear driver, still causes BSODs.
The machine runs perfectly with all other WLAN adapters I have installed on it, and no wlan adapters at all.
If you run Win7 with Gigabyte z68 mobo you definitely don't want to waste your money on this device. I won't even bother trying it on any of our other production machines

2 out of 5 eggsProblems with Z87 motherboards

Pros: Good 2.4 & 5.0 performance. Includes stand. WPS button on adapter. Sleek appearance.

Cons: Causes problems on motherboards with Z87 chipsets. Netgear seriously lags with driver updates. Large profile takes up adjacent USB ports.

Other Thoughts: I had no problems with this for over a year on a motherboard with an X58 chipset. I upgraded to a Z87 and suddenly there are weird USB problems. Process of elimination proved that this adapter was the problem. Have tried everything possible to resolve it, and even went as far as reinstalling Windows 7. I've tried the generic MediaTek/RAlink drivers (Netgear's official ones are crippled and seriously behind) and that doesn't solve it either.

Contacted Netgear support and was basically told to pound sand. Shame, because it's actually a good adapter other than this bizarre incompatibility.

5 out of 5 eggsEasy to install - works like a champ!

Pros: Installation was a breeze. Now getting faster speeds and longer range (along with other network options what were out of reach of my other wireless).

Cons: none so far

Other Thoughts: I wanted to keep my Toshiba laptop internal WiFi (not to delete drivers) but wanted fater speeds and a longer range at times that I would have heavier WiFi needs. Was looking for a USB device that was not bulky. I initially tried a ASUS USB-AC56 however had blue screen of death (Win 8.1) every time I plugged the device in due to conflict with the Toshiba drivers (even though the Toshiba drivers were disabled). The Netgear WNDA4100 installed like a breeze and works like a champ even with the Toshiba WiFi drivers active! This is just what the doctor ordered!

1 out of 5 eggsWorst Wireless adapter I've Ever had

Pros: It works great for the first 1st month

Cons: It stops working sometimes as in connection drops, I cant play any games with it because the connection is terrible. After a good 2-3 months I can barely load web pages and I know it is not my computer because the second i go to Ethernet connection everything runs perfect. Not worth $60.

Manufacturer Response:

4 out of 5 eggsWorks very well with Windows 8 x64

Pros: - Fast
- Windows 8 compatible
- Easy setup

Cons: - Large: if you're using a laptop, expect to lose at least 1 adjacent port due to the adapter blocking it

Other Thoughts: This review is mostly a response to others that claim the adapter doesn't work with Windows 8. Apparently shortly after the OS was released, no drivers existed. However, Netgear published Windows 8 drivers in Q2 2013, and now lists Windows 8 support on their website.

*HOWEVER* because there's no telling which drivers the card you buy shipped with, it's a good idea to set it up as follows:
1) *Before* connecting the adapter, download and install Windows 8 driver directly from Netgear support
2) Connect the adapter when prompted. It will work perfectly from then on out

The only drawback of the adapter is that it's very much on the bigger side of things.

5 out of 5 eggs

Pros: really solid net card been using it for over a year and its lasted longer then then routers I've bough in in time. reliable and decent speed great for browsing and streaming and most gaming

Cons: little slow for some online gaming like lol

Other Thoughts: really for an everyday use net card I don't really see why you would get anything else its just worked flawlessly for me since the day I got it and the only reason I'm upgrading is just higher performance for gaming

1 out of 5 eggsREFURB IS NOT SO GOOD

Pros: Nice sleek design.

Cons: Took forever to be recognized and install drivers. Maybe I should have purchased new instead of REFURB. I downloaded the latest drivers from Netgear website and finally got it installed but it has intermittent drops and that's probably the reason it was returned. Called netgear support, could not understand the person on the phone. I have owned many Netgear products in the past and have had no issues whatsoever. There has to be a reason why this unit was refurbished. I won't buy refurb in the future.

Manufacturer Response:

Hey Wilsondr,

We apologize for your frustrations with the WNDA4100 refurb. If you need additonal assistance we recommend using our forums-- there are is plenty of active users and personell available there to help!
