That flash bug is annoying, the Cisco software engineers have a script for 
identifying and fixing some. It doesn’t fix all issues but can at least 
pre-identify and allow you to manually sort before it becomes an issue. I’ve 
only just started playing with it. We’ll see if we have any failures at 
upgrade. We’ve been having a few 2702i’s go down recently while faulty cables 
are replaced.

It’s called wlanpoller, does plenty of other things but since we are doing an 
upgrade shortly I’ve just started with that. You can ask for it from TAC
I got info about this while at Cisco Live Melbourne this year.

Hi Lee,

This is a serious consideration at the moment and would be doing so if we 
weren't hit by a significant flash corruption bug, which would result in a 
number of APs failing due to the software change, requiring thousands (and 
possibly tens of thousands) of contractor dollars to have them replaced since 
we don't run console cables into our APs, due to the reboot.  We'd prefer to 
only do this once more if we can (i.e. to get away from the flash corruption 
bug).

Cheers,
Tristan

Any thoughts of rolling back to older code, rather than living with the issue?

Hi all,

We have two TAC cases, one for the Dell 1535 and the other for the general poor 
connectivity issues.

We rebooted one AP yesterday and the customer tells us that their connectivity 
improved.  In another instance, we rebooted an AP and the situation did not 
improve (in fact, we replaced it - still to no avail).

We have over 1800 of these deployed so the impact is widespread.  All in local 
mode.

I would be very keen to hear if anyone else would be willing to share TAC case 
details for any tickets logged to Cisco for this issue.

Cheers,
Tristan

Ours are also local mode.

Replication could be challenging, we have 27x 702w’s  currently but I’ve only 
come across 1 confirmed repeat offender. Though some of those are in student 
accommodation, so I suspect a few of the complaints there could be related. 
However getting details to troubleshoot are somewhat more challenging there.

Anyone worked with TAC or had a bug outside of what Stephen mentioned? I don’t 
recall seeing those logs when looking at this one. Haven’t been in contact with 
TAC due to low use/impact vs other work.

I see thanks. I do not think I’ll have time but if I can I’ll setup a 702W and 
see if I can repeat.  If I can I’ll try to do an over the air capture.

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