With both the Netgear and Alfa Adapter, I get roughly 11 MB/s which is way better than what I used to get with my old router. If I go two metres away from the router, I get 8.5 MB/s. About 15 feet away with one wall in between, I get 6 MB/s.
The only 5 GHz capable devices I have right now are two smartphones and I'm barely getting 2 to 3 MB/s on both 2.4 GHz and 5 GHz (using iPerf app with the same commandline arguments as above).
I'll buy a 5 GHz adapter this week and run another test and post results.
If anybody else is willing to run a test with their ddwrt (or stock) running E4200, it'd be great if you could post results along with the build you're using.

wow,
I get 40+ mb/s on most of my router:
here is what I use:
Windows 7 Intel 6300 AGN 5Ghz N to Windows Home Server 2011 1Gbps LAN.
WLAN to LAN - 25MB/s (200Mbps ) MAX is what I see.
LAN to WLAN - 12.7MB/s MAX - seems like something is holding it back and I can't figure it out.
Doesn't matter much as i'm usually not pulling data to the laptop and Xbox and WDTV are connected via LAN so they get all the bandwidth they need but still weird.
2.4Ghz around me is crowded as hell, got about 25-30APs. Still get about 6MB/s though.
I'm curious... I take it by those drivers that you're using Linux? It's rather common for manufacturers to create buggy windows drivers that report the wrong connection speed, but I would expect open source drivers in Linux to report the correct speed. Did both adapters report 60mbps in the OS? Your initial results were ~90mbps of throughput that would require >=130mbps link rate.
Your initial results were straddling the line of performance for 100mbps Ethernet and I don't notice any mention of your nic, is it gigabit or 100mbps?
Is the xmit power the only change in your latest test?
@everyone - keep up the testing, it would be great to have more numbers to cover all the possible combinations of MIMO streams, channel widths, and spectrum to add to the wiki.

Looking for bricks and spare routers to expand my collection. (not interested in G spec models)
Yes, I'm using Linux on both ends. The desktop PC is running Fedora 16 x86_x64 and has a Gigabit port. The laptop on which I'm using the WiFi card, is running CentOS 6 32bit.
The WiFi drivers that I'm using are from the December 2011 build of compat-wireless.
I bought a few more wifi cards so I'll be running more tests the coming days so I'll check the reported speed again. I checked them only once before running the tests. It does seem to be reporting a lower speed than it really is so my guess is that they probably get updated when card is sending/receiving packets.
The transmit power is the only other change in my tests.
Edited to add: When a friend of mine came over to my place and connected his laptop to my WiFi, we got terrible speeds over WiFi with the same distance from the router. He was using 64 bit Windows 7 with its built in WiFi (I think it's a Broadcom one). I don't have a windows machine at the moment but I'll try to get one soon so we can compare the difference in speed.
yeah you need interference mitiagation mode enabled... that will help alot
send this command to the router
wl -i eth1 interference 2
from the administration commands, no reboot or anything necessary.

Do you recommend this for every Broadcom Device or only for the E4200? _________________ Linksys E3200
