Bigfoot’s Killer-N 1102 Wireless Networking vs. the World
by Jarred Walton on August 10, 2011 10:38 AM ESTNetgear 2.4GHz Obstructed Performance
Our next test is the same router as before, only now we’ve moved the laptops to the opposite side of the house. For this test, the router is still upstairs, but the laptops are about 50 feet away (direct line) with several walls and a floor in between. As you might expect, performance is lower on every laptop in every test, though some controllers hold up better than others.
The Bigfoot 1102 leads in most of the tests, with the Realtek and Atheros generally claiming second and third. Once again, the ASUS K53E performs better than the Clevo sample unit in this test—much better in fact—despite both using the same Intel Advanced-N 6230 chipset. Also note that all of the cards do quite a bit better at receiving data than at transmitting (see the NTttcp charts), which makes sense as most laptops don’t put a ton of power into their transmit radios. It’s interesting that in our obstructed tests, the Intel 6230 (in the K53E) and 6300 along with the Atheros AR9287 all manage higher transmit rates than the BF 1102 with NTttcp, though that advantage doesn’t translate over to Netperf.
The Bigfoot 1102 still maintains a decisive lead in the latency tests, with the Realtek 8188CE nipping at its heels. Oddly enough, latency is actually lower on a couple of the cards (the K53E with Intel 6230 specifically), but that’s probably in part because the connection rate is no longer as high. Most of the laptops connected at less than 130Mbps, with a lot of variance in the speed as the cards frequently renegotiate their connections. Bigfoot also continues to dominate the copy time for lots of small files, again illustrating that their “secret low latency sauce” helps in areas other than gaming. The single stream Realtek chipset comes in second in that test, and it has the second lowest latency of the tested controllers.
The takeaway here is that even the best network cards won’t perform all that well without a clear signal. If you have a large house or office and you want to provide good coverage, setting up multiple access points would be necessary to obtain optimal performance for every room. We’ll look at how far the laptops can get from the router before experiencing connection problems later, but in most houses the Bigfoot 1102 should get a good signal.

Jarred, if you asked me about a year ago... I never thought I'd recommend a Netgear product. My past encounters with their networking devices has been less than stellar. Even with that, I decided to take the plunge, and I purchased a WNDR3700 a few months back. It has treated me rather well so far and that's on stock firmware. It is DD-WRT compatible; so if you prefer their firmware, you're good to flash.Compared to the Airport Extreme, it is a bit weaker on the wireless front as it only supports MIMO 2x2, but its newer sibling, the WNDR4000, supports MIMO 3x3.
The one feature I'd definitely argue for though is simultaneous dual-band. I don't think most people have homes with only 5Ghz devices. So with just a dual-band router, you'd be limited to 2.4Ghz anyway.

Any idea why the (default parameter) netperf tcp transmit results are so horrible across the board? I just ran netperf on my Advanced-N 6200 notebook and got 190Mbit/s to my Cisco E3000 router, basically the same value as with iperf and netcat and every other benchmark.Rick83 - Wednesday, August 10, 2011 - link
It would be fairly interesting to see the difference between the Killer NIC, server NICs, laptop NICs and desktop NIC's from different vendors (and in different implementations).As I run only a SSD in my desktop, and have my user profile residing on a NAS (Intel i5 powered NAS, though, not limited by the available cycles and RAM) on a RAID 5, with reasonable linear throughput, network performance is quite important for me, as it accelerates such tasks as generating thumbnails of files, listing large directories, local decompression (that's probably the worst offender, and with large archives I do this on the NAS directly) and many tasks that access my user profile that may be latency or throughput limited.
For this reason I recently specifically got a mainboard with Intel network adapter, hoping for enhanced performance, but only realizing, that I'd have to hack the .inf to get driver support under my OS.
On the NAS, I am currently using the RTL 8111D chips, one connected to the switch and the other to the modem. If using a decent chip increases my samba/nfs performance, I'd put down the 50 euros for the intel pro chip in a blink.
Also you could test supported cable length, jumbo frame support, documentation (with some cards the maximum MTU is not properly documented, and it takes ages of non-fragmented pinging to discover the correct MTU) and performance of teaming and fail-over mechanisms.
Also, 5Ghz was something that I tried in my parent's home, but we couldn't even connect a machine that was one ceiling and wall away, at less than 10 meters distance. Might have been just a spectacularly bad router (Linksys 320N) or maybe 5GHz is really just for line-of-sight applications.

Jarred,I think it would be nice to run tests of multiple wireless network interference like the kind observed in apartment/townhouse/condo situations. This is a big problem that no one seems to ever test/talk about.

True that. I live in a condo building in uptown Charlotte, NC and every unit has a wireless router of one kind or another. To make matters worse, the elevators seem to interfere somehow -- along with every wireless phone and microwave, the acres of glass and the steel structure. To top it off, there's an office building right next door which has many wireless systems on its own.ckryan - Wednesday, August 10, 2011 - link
Sometimes it seems like someone has cast some manner of evil voodoo on WiFi as a whole.I bought a Killer 2100 NIC because I thought it was a good idea -- and it was on sale. It is better than Intel's on-board Ethernet (and better still than Realtek) if only just barely. In reality, I just liked the idea of dedicated hardware for my networking needs. It really did make a difference, and really is some good stuff, but probably not worth the substantial premium over garden variety PCIe NICs (for most people). I'm glad I bought it... but only because it was on sale.
The Killer product line is in the position of having a product family which does perform mostly as advertised, but becomes a tough sell when you already have onboard ethernet or wifi. It has to be difficult to sell a consumer NIC that costs as much as a 80GB SSD or mid range video card. For $65 or $70 it's great. At $140, not so much. As such, I'm glad to see them trying to put their hardware inside other hardware, like networking cordon bleu. Shoving their "NPU" onto the PCBs of video and sound cards, motherboards, and laptops is a good idea and if nothing else add a little variety to the mix. It would easily be worth an extra $25 -$35 premium for a motherboard in any price range to get their NIC over the bog standard Realtek. It can't possibly cost more than the NF200 or Hydra chips on mid and high end mainboards and is surely worth an extra $20 on top of a laptop as well. Whether they can sell this particular device sans lappy at a reasonable price or even at all remains to be seen.

I'm on a wireless card and want to test my latency. Where can I find this GaNE tool?Flunk - Wednesday, August 10, 2011 - link
This result really surprised me, I was expecting results like their wired products (no difference). My guess is that the biggest factor is the support for more channels but the performance really does seem markably better. I'm gearing up to by a new Alienware laptop near the end of the year and I may very well check the box for a Killer-N upgrade.StormyParis - Wednesday, August 10, 2011 - link
Isn't there a wide gap between what tech sites review, and what users use ? I know it's part of the purview of a tech site to go for the 0.001%-of-users, bleeding-edge stuff, but... has anyone ever seen a review of mainstream Wifi adapters/laptop anywhere ? As one of the 99.999%, I'd be interested !JarredWalton - Wednesday, August 10, 2011 - link
Bigfoot offered, so I thought, "Hey, this could be fun." Well, it wasn't. WiFi testing is a real pain in the butt I've decided. Still, it would be good to look at some other products. We might come back to the subject in the near future; I'm going to see about soliciting a bunch of different WiFi adapters and see what turns up. Obviously, I have at least the 6230 and 6300 from Intel. I want to add the Killer 1103, some Broadcom stuff, etc. Really, I'd want to focus on just dual-band cards, though -- anything that can't do 5GHz becomes less interesting after playing with the Linksys E4200.
