Are you using windows zero config nwetwork management for the adapter?

I wasn't aware of any problems with SP3 and XP with wifi adapters. I use Realtek chipset USB adapters and they work fine with SP3 under XP. The Asus wl-167g USB adapters use the Ralink chipset. The Ralink driver should have it's own wifi management program. It's always best to use the one supplied with the adapter, rather than the Windows zero configuration option. Sounds like you have that covered.

How are you measuring how "powerful" these are? Signal strength? Test equipment? Netstumbler? Kismet? >i am using an asus wl-167g usb adaptor. one of the few that works with >windows xp sp3 Most current USB adapters I've tried work with XP SP3. I'm not sure where you obtained the idea that this is the only one that works. Can I presume that you've attempted to use other USB adapters? If so, are the drivers for those adapters still installed on your unspecified model computer? If this is the case, you might consider removing them using the control panel, add-remove, as they are probably fighting each other. You mention elsewhere that your router is a Dlink DI-624. (In the future, it would be helpful if you would disclose what you're doing and what equipment you have to play with). I'm quite familiar with this router, which has it's collection of problem. 1. Is it a DI-624 or DI-624+ ?? 2. Is it a hardware revision A, B, C, D, or E ?? They're all very different hardware. 3. Do you have the latest firmware installed? Check on the Dlink web pile. 4. Why are you using WEP? If it's because the firmware only supports WEP, you have a very old version. I suggest WPA or WPA2 and a more useful alternative. >i am using asus's program for the connection but it makes no >difference which one i use for the speed I'm not familiar with Asus's program. Does it have a name or preferably a URL to see what it does. It's possible that you're measuring the wireless connection rate, instead of the thruput. I can't tell without looking at the program. You might be expecting a bit much from the DI-624. Several of the early models were problematic. I don't think I've ever seen one move data at much over about 15Mbits/sec. Unfortunately, the DI-624 is no longer listed on the benchmark tables at: <http://www.smallnetbuilder.com/index.php?option=com_wireless&Itemid=&chart=29> Please note the WIDE range of measured thruput (which rarely corresponds to advertised claims). Frankly, it's an old router, which might require replacement in order to obtain full speeds. One clue might be to obtain your wireless connection speed. In order to obtain 16Mbits/sec thruput, you will need to have at least a solid and stable 32MBite/sec wireless connection. Your Asus connection utility, Netstumbler, or WirelessMon, or other monitoring utility should show this speed. My guess(tm) is that if you're only getting 5Mbit/sec, your unspecified model computah is probably stuck in 802.11b mode, probably because of excessive interference, or more likely because you're using a USB 1.1 port instead of USB 2.0. If you want to nail down the exact cause, it's often best to diagnose by replacement. The first step is to take your cable modem out of the picture. Find another computer, plug it into one of the LAN ports on the DI-624, and fire up iPerf or preferably Jperf in server mode. Then, run the Jperf on the client computer to obtain thruput number for only the wireless link. <http://openmaniak.com/iperf.php> <http://code.google.com/p/xjperf/> <http://sourceforge.net/projects/iperf/files/> Be sure to run an ethernet to ethernet benchmark, as well as the usual ethernet to wireless benchmark, to make sure that the computers are faster than the wireless link. < -- Jeff Liebermann jeffl(a)cruzio.com 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558
