I was just curious, are these 702w APs in flex connect mode?

The user moves down the hall to a 3602i and no worries, moves back to the 702w and it’s a problem. Other devices including her iPhone is fine. Strangely it seems to occur randomly (days or weeks apart), and always the same device. Rebooting the AP will resolve it, or just time! But waiting for resolution could be hours.

Our latest issue, that seems to again only impact the 702w involves a couple of MacBook Air users, running either Sierra or High Sierra. A debug shows that on occasion when trying to connect to a.1x network they make it as far as the DHCP required state and then never request an IP. They hit the timeout, the WLC deletes the client and the dance begins again.

Ever since moving from 8.3.112.7 to 8.3.135.2. What we see: * Devices with the Killer NIC 1535 authenticate but can't pass traffic. * Apple devices will connect, pass traffic for a while, then go dead. We believe we may have seen this on a 1532 series AP as well. Debugs don't seem to give us much. 3702i, 3802i appear to be unaffected.

We have a student on campus who intermittently cannot connect to our 802.1x Student WLAN when trying to connect to a Cisco 702w access point installed nearby. They can connect to our open Guest WLAN. I should say that they are fail to connect to Student more times than they succeed when in their Student Residence. On campus they are able to connect to Student. I recently brought them down to my office to have them try and connect to a 702w that I had set up specially for the purpose of this test. *Client Details:* · Acer Aspire F5-571T Laptop · NIC: Qualcomm Atheros QCA9377 · Driver Version 12.0.0.309 · O/S: Windows 10 Home Client has Symantec Anti-virus installed Windows updates and driver versions were all validated. During testing I noticed that the client completes the AUTH phase and enters RUN state. At this point it frequently seems to stall and doesn’t make it into the DHCP Socket Task portion of the client/WLC/DHCP exchange. The only thing that the testing proved to me is that the client doesn’t like Cisco 702w APs, as I saw the same results in my office as I saw from them in Student Residence. Of note is that the problem seems to become particular pronounce when they roam from Guest to Student or vice versa. Disabling the Symantec firewall seemed to improve, but not fully resolve the issue. I should also point out that due to the unique way that our Residence townhomes were constructed wall mount APs are our only option. So this one has me beat!
