XploRR Posted April 7, 2012 Report Share Posted April 7, 2012 (edited) Latency solved on my Atheros AR5B97 Wifi Adapter on WinXP using my own modded driver. I have been searching for a driver for my Atheros AR5B97 wifi adapter for Windows XP, because I downgraded the Win7 OS on my ACER Aspire 7750 to WinXP. But all the drivers I found (including those on this forum) did not work properly. They did not work or generated latency (checked via DPC latency checker). Because I use my laptop as a DAW (digital audio workstation), I need as low latency as possible, and glitches are not acceptable. So, what I did was experimenting with the settings of the latest official driver I found: 9.2.0.480 for XP. I noticed spikes every 30 seconds in DPC latency checker when my Atheros card was active. When I disabled the card, the spikes were gone, so I knew the spikes were due to the Atheros Wifi Adapter. Then I changed the parameter: Scan Valid Interval: 120 (it was 30 I believe) and I noticed the spikes were every 120 secs or so. So I guess the spikes of latency have something to do with this Scan Interval parameter. I also noticed that in the modded drivers that don't work for the Atheros AR5B97 on WinXP, there is an extra parameter called: Background Scan that you can put to Off. So I thought, if I can have this parameter available in the latest driver, I could try to set this value to Off. So I replaced the inf file and modded it with the code I found in the last know XP modded driver that does not work for this card and added an entry for my AR5B97 card. I named my driver 9.2.0.504 and I replaced the current driver and I saw the value appear in the settings. I changed the value for Background Scan to Off and voila the spikes of latency are completely gone. :) Update: I noticed that the LED of the adapter was not working, so I added code to show the LED (based on the post by Abrasax). In attachment (see next post) I have included my modded driver 9.2.0.504. I have to say: please use at your own risk and I only tested it with the Atheros AR5B97, but it might work with other Atheros Wifi adapters on XP. Don't forget to change the parameters: -Background Scan: off -Roaming Policy: very low -and Scan Valid Interval: 120 (max) Let me know if it works for other cards.

DorinAlex Posted April 14, 2012 Report Share Posted April 14, 2012 hello helpful folks i indeed looked around this thread and unfortunately couldnt find an answer i'm setting up xp on a fujitsu lifebook ah530 it has an AR9285 adapter with PCI\VEN_168C&DEV_002B&SUBSYS_153710CF&REV_01\4&1D521A10&0&00E1 my main aim is to set the laptop up as an access point (as if the laptop was one of those devices you hook up to your broadband) i read on the internet that this is a new thing on new wifi adapters and it said there that atheros ones are apparently leading the way. so i'm really hoping it will be possible... my driver version is 7.7.0.429 from fujitsu's website i really don't know how to move forward since there are many posts with drivers but can't figure out which to use anybody know how to enable the access point emulation on my kind of chip and maybe where to get the drivers for that to work? many thanks for your help, any input really appreciated Quote Link to comment Share on other sites More sharing options...
nukestar Posted April 29, 2012 Report Share Posted April 29, 2012 Anyone with ar5b97 chip will want to read this. I found the solution for LED not working. in the netathr.inf file find the lines HKR,, linkLEDFunc, 0, "35" HKR, , swapDefaultLED, 0x00002, "1" and change the first from 35 to 8 I also added the two lines from the original driver right below the first two HKR, , gpioPinFunc0, 0x00002, "8" HKR, , gpioLedCustom, 0x00002, "3" also under the [atheros.DelReg] section find HKR,,gpioPinFunc0 HKR,,gpioLedCustom and delete them. Save the inf file and then normally install the driver. It's working as stated at the beginning of this thread. When connections are available there is a long blink, and when the adapter is connected it blinks in accordance to network traffic. Also if anyone else is having the issues with LED let me know and i'll see what i can do. I attached the fixed inf if you are too lazy :) Thanx. Work very well :) Quote Link to comment Share on other sites More sharing options...
arqmarcel Posted May 7, 2012 Report Share Posted May 7, 2012 Same problem. No sufficient range using AR9285 in a Z470 Lenovo notebook. Using modified driver 8.x solved the range problem, but, I'm having much packets lost. After enabling all the possible configurations of AR9285, what can I change to solve he packets lost issue?

arqmarcel Posted May 8, 2012 Report Share Posted May 8, 2012 I called to Lenovo support. I explained the sign lost if I move away more than 3 meters from the router. Buddy answered me that Lenovo just serviced ensures up to 3 meters and still made me do a test, ping the system itself, i.e. to have 0 packet loss. If I had spoken q no more connection took 1 m, would say that only guarantee up to 1 metre ... joke ready like we say here! Simply disappointing Lenovo post-sales and support!

gahbmwm5 Posted October 15, 2012 Report Share Posted October 15, 2012 All I did was change some of the strings....no tweeks.....so that I had a newer driver....I typically do not try to tweek any Wireless, or Sound cards as problems always develop.....so you are correct... But most importantly for moi....is that this driver has not disconnected once.....not one time did I have to reset the wireless adaptor...like the driver mentioned above that came pre-installed with this newly purchased laptop.. :hump: Quote Link to comment Share on other sites More sharing options...

Ago Posted November 30, 2012 Report Share Posted November 30, 2012 Guys. I have a desktop PC with TP-Link wireless adapter which uses "Atheros AR922X" drivers. I have 2 problems. 1. My computer often freezes. 2. Sometimes when I turn on the computer the adaptor is not detected and wireless is the only way I have to access a connection. I used your modded drivers and my problems were gone for a while but they came back. I changed my pc components one by one. The only one I didn't change was this Tp-Link adaptor. This are the problems the modded driver solves or not? Should I search for the solution in another place? It happens to somebody else?

hood3311 Posted January 2, 2013 Report Share Posted January 2, 2013 Is the AR 9271 not supported? Â I can't find it in any of the modded drivers I've downloaded.. It goes right from Ar922X to AR9280. Â Does anyone know what I could use or do to get my AR 9271 working with this modded driver? I've tried using some of the closer versions that aren't "9271" and it says "This device cannot start." I've looked everywhere and any help is greatly appreciated :) Quote Link to comment Share on other sites More sharing options...

Canon_Man Posted January 18, 2013 Report Share Posted January 18, 2013 Hello,  Very new to this forum and not overly technical when it relates to drivers for components added to a PC desktop.  I installed a D-Link DWA-552 Extreme wireless adapter in my Gateway 500S work horse about a year ago. Never gave memory usage too much thought until I had a driver issue with my Canon L6000 laser and had to finally reload Windows XP Home yesterday. That was a chore in itself because MS moved everything and updating with SP1, SP2 and SP3 was more grief than I could handle. Done now.  Anyway, I reloaded the driver for the DWA-552 that came with it and noticed some things running that I had not seen before. Proc(s) associated with the wireless manager software I believe. I remember seeing it spike to about 300,000Mb of RAM and decided that wasn't going to be Gen Op Pro for me or the desktop.  Searching for info on drivers that could be loaded without the manager components, I found this site.  I've tried two already:  atheros_v7.6.1.170_v1.21 and atheros_v7.7.0.259_v1.26.  Must be doing something wrong because they do work, but the wireless D-Link will only connect at 54Mb/s. It connected @130 Mb/s with the D-Link driver software before I started monkeying with it.  We're running a Cisco E2500 dual band router. The higher channel is running on channel 48 @ 5.24GHz, and the lower frequency is running on channel 11 @ 2.452GHz (Both bands are set with a channel width of 20MHz to 40MHz)   I did try switching the lower frequency to channel 9 to see if that helped.  Ideas, suggestions?
