Ah, my bad. I read 2610 and thought 3610 which is what we're running. A good example of why I shouldn't types emails before the first cup of coffee takes effect. :)

This is happening on our a b/g’s. Thanks, Reese From: [email protected] [mailto:[email protected]] Sent: Monday, June 04, 2012 7:53 AM To: Enterasys Customer Mailing List Subject: RE: [enterasys] Dell disconnect from Hipath AP 2610 If you haven't already tried, it might be worth disabling ADDBA temporarily to see if that 'fixes' the issue. ADDBA is disabled on our network due to an Intel-related bug with the 5100/5300/6200/6300 series chipsets. After a certain amount of traffic is transferred, these Intel clients stop receiving traffic from the AP, yet still remain associated. I was told Intel confirmed the issue in their drivers and is working on fix. At any rate, we're running v8.11.02 here w/ADDBA disabled and haven't yet received complaints from Broadcom users. At least, none that have been forwarded my way. :) Derek Johnson | Data Communications Coordinator FORT HAYS STATE UNIVERSITY 415 Lyman Dr. TH 101, Hays, KS 67601 (785) 628 - 5688 | [email protected] From: "Borel, Reese" <[email protected]> To: "Enterasys Customer Mailing List" <[email protected]>, Date: 06/02/2012 10:08 AM Subject: RE: [enterasys] Dell disconnect from Hipath AP 2610 8.11.01. We haven't installed and configured our second HiPath controller at this time (still in the box). We see this problem with only one controller in the loop. Now that you mention it.... I don't remember this being an issue before the upgrade to 8. You may want to wait.

This is our environment as well, and we are not seeing the problems but are still running 7.41 we are planning on moving to newer firmware soon, but this may have us wait it out a bit more. I can say we saw something very similar to this some time ago, and it turned out to be a configuration accident that occurred where we accidentally set an interface on two controllers to the same IP. The controllers did not complain, and the clients periodically switched from one controller to the other (depending on who answered an ARP request first). When they switched it resulted in a disconnect. Reconnecting would re-establish with one controller or the other and be OK. we basically figured it out by looking at the arp tables of a connected laptop and a disconnected one (they didn't have the same entry). ------------------------------ James Shuttlesworth Network Technologies Manager Ursinus College Information Technology [email protected] -----Original Message----- From: Borel, Reese [mailto:[email protected]] Sent: Saturday, June 02, 2012 9:19 AM To: Enterasys Customer Mailing List Subject: RE: [enterasys] Dell disconnect from Hipath AP 2610 Jeff, We have the same problem. Our Dell's (broadcom as well as intel cards) won't stay connected. Ours drops way more than 1-2 times an hour. They seem to disconnect less when using a SSID with PSK instead of RADIUS auth. Plz try it and let me know if you get the same results. This is really a problem for us since Dell laptops are the corporate standard and there is no problems for users when they go to other locations using other vendor wireless. We are using all 2620's. i don't think the problem is in the AP. We have had the RADIUS team look at logs when these drop. There are no 'disconnect' instructions being sent from the RADIUS server. We have a GTAC case open on the issue and were told it was going to be fixed in the last release of firmware. We upgraded and are still seeing the problem. I'll keep you updated on our case.

We are running AP3610's and at one school seem to be experiencing an occasional disconnect from the wireless network. A user can be in an area of great signal strength and can lose the connection 1 or 2 times per hour. A quick disconnect and reconnect establishes the connection again and all is fine. The Dell laptops are using Broadcom wireless cards.
