Wireless Performance
NOTES:
• The readings in the Signal Quality columns are actually Signal Strength (in %)
• Testing was done with a NETGEAR HR314 802.11a router and ME102 802.11b Access Point as test partners
The charts above and plots below pretty much tell the story of the WAB501's performance. Let's start by looking at Plot 1 that shows 802.11a tests.
Plot 1: 802.11a performance

11a mode performance was among the best 802.11a-only adapters that I've tested with solid 21-22Mbps throughput with or without WEP enabled in 1X mode. Enabling Turbo mode boosted performance almost 50% to an average 31-32Mbps, with a max throughput of about 37Mbps. As usual, I tested Turbo mode only under Condition 1, because it tends to more negatively affect performance under lower signal conditions. I was pleasantly surprised to be able to complete test runs in both Condition 3 and 4, since some 802.11a-only products aren't able to handle these tests at all.
Figure 2 shows the 501's shocking performance in 802.11b mode!

No, I didn't make a mistake and use the same plot data four times. The 501 is the only 802.11b client adapter that I've ever tested that showed such consistent (and excellent) results under all four test conditions. It just cruised along at almost 5Mbps without missing a beat. Plot 3 shows that you do get about a 4% throughput reduction when you enable WEP in 802.11b mode, however (and shows you 802.11a WEP test results, too). But the consistent throughput performance more than makes up for that small hit, and you shouldn't have any qualms about running with WEP enabled in either mode.

In all, I have to say that I was extremely impressed with the WAB501's performance in both 11a and 11b modes, but especially in 802.11b mode!

I have tried many many wifi adapters…..and I can say one thing for sure…
..I don’t know about you guys, but for me UAWIFI UA3 usb adapter is the BEST.
No other adapter can compare to this baby, it is VERY powerful.
There are few people sell them on ebay, but I got mine directly from mft. website http://www.uawifi.com price is same.
I also know that it is Made in USA, so at least by buying it I am supporting US workers…not Chinese.
Well. Got mine from uawifi.com.
Looks good and the range is good.
stop spamming everywhere.
Ou3ZiE Good point. I hadn’t thought about it quite that way. 🙂
Saw yesterday on my neighbours roof strange device with logo UAWIFI
Made a search on google, and now I know what it is))))
