The problem with 802.11n is that with most setups the Data frames going in one direction will be missed. Unfortunately for people who dabble in WiFi sniffing, 802.11n also makes it virtually impossible to do traditional sniffing. 802.11n is a great technology that increases both the speed and the range (and even the security, in a way) of your WiFi. Let's start off with the 802.11n thing first. And to make matters worse today I finally got to use my D-Link DWA-160 dual-band 802.11n USB adapter with AirMagnet WiFi Analyzer so I really wanted to do some sniffing.
The technology is revolutionary and inexpensive and blah, blah, blah, but it's dang near impossible sniff it! Oh, does this tick me off. Or try to get A WNDA3200 on eBay.I am going to have to expand upon this topic in another post somewhere down the road, but 802.11n continues to annoy me. You could of course also gamble and try to get the right hardware version of eg. you want to connect it to a Raspberry Pi Zero. Thus it appears that the only safe bet remaining is to get a TP-Link TL-WN722N, which, however, has an external antenna connected to it, which makes it rather unhandy if eg. Which brings us to the next problem: where do we get one? Many of the devices listed at Wikidevi are not available in Germany and some manufacturers change their chipsets between hardware revisions more often than some people their underwear: Productģ: Some dealers advertise a Netgear WNA1100M which is actually a RealTek-based WNA1000M!
If we look at Wikidevi’s Atheros chipset table, we’ll see that what we’re ideally looking for (IEEE 802.11n, USB) is an adapter based on either the AR7010 or the AR9271 chip. And small meaning it should have an internal antenna. Now say we’re looking for a small USB Wifi adapter, IEEE 802.11n, because there are no IEEE 802.11ac USB drivers in the mainline kernel yet. They have a long tradition of both feature set and decent drivers: the old MadWifi drivers were the first Wifi drivers to actually support virtual interfaces on Linux (yes, MadWifi ha issues of its own with its binary HAL explaining why it never got merged into the kernel). If you have some experience with Wifi adapters and drivers, especially under Linux, you’ll know that in general Atheros chips are what you want. When looking for Wifi adapters, there are reasons why you would not just go ahead and buy whatever your favorite $DEALER has in stock.
