Hello Derek,
I have noticed that on our HiPath deployment both aggregate MPDUs and ADDBA support are disabled by default... We are in the process of converting our RoamAbout wireless network to HiPath and we have noticed there are lots of sub menus we still need to investigate and see if there are knobs and buttons that we should tune to get better performance, but at this point we have only really focused our testing on Airtime Fairness... so I was wondering if you could let me know what led you to enable both of these? Thanks Andrew ________________________________ From: [email protected] [mailto:[email protected]] Sent: viernes, 02 de septiembre de 2011 15:19 To: Enterasys Customer Mailing List Subject: RE: [enterasys] Enterasys HiPath and Intel Clients Working with GTAC, they were able to isolate the two features causing certain Intel adapters grief in my test environment -- A-MPDU and ADDBA. Since disabling those features on the AP radios, my Intel 1000BGN testbox hasn't had any trouble sending/receiving traffic. To answer your specific question, the vast majority of complaints have come from users with HP systems running Windows 7 SP1 64-bit. We've seen a few Vista SP2 32-bit and various Dell/Asus Windows 7 SP2 32-bit systems in the mix as well. Two systems ran Atheros or RealTek and both users reported that a driver update fixed their issues. All others have had Intel adapters of some kind, with the majority equipped with Intel 1000BGN. There's a significant Mac presence in these particular buildings, and we've heard nothing but good things so far. However if memory serves, Apple wifi hardware is either Atheros or Broadcom-based depending on the device. My gut says this is an Intel-HiPath bug, something to do with the behavior of the Intel driver itself.

Can this be reproduced on *nix, Mac, others? Could this be a drivers issue on the OS, could this be a firmware issue on the H/W? 5c Jolyon Ansuz Senior Network and Communications Administrator Communications Infrastructure Information Technology University of New England Armidale NSW 2351 P: +61 2 6773 3568 From: [email protected] [mailto:[email protected] <mailto:[email protected]> ] Sent: Thursday, September 01, 2011 6:31 PM To: Enterasys Customer Mailing List Subject: [enterasys] Enterasys HiPath and Intel Clients Is anyone out there having any trouble with Intel WLAN adapters and HiPath? Specifically, we've had ~100 student laptops come in with Intel 1000BGN adapters - latest drivers - that remain connected to the network, but stop receiving traffic from our 3610 APs. Disconnect/reconnect and things are fine for a short while, then stop working again. Some clients stop receiving traffic immediately after obtaining an IP address. Open SSID, WPA2, it doesn't matter. I've also had trouble with random versions of the Intel 5100 adapter. 5300/62xx/63xx only seem to experience occasional packet loss but otherwise no major problems. Atheros/Broadcom adapters exhibit none of these issues. I'm currently working with support, but it's pretty slow going so I thought I'd ping to see if others are having the same issues. Running firmware 7.41.05.0003 here. Cheers!
