I posted to this discussion some time ago. Since I needed reliable operation, I switched to an actual Cisco WAP product which cost several times as much but has worked flawlessly for months with Windows XP and 7, IPads, IPhones, Androids, etc. Then, as a private investigation, I left the old WAP in place and operating. Occasionally I try to use it.
This is what I think I have learned. The old WAP works fairly well in isolation but fails when it has radio competition. There are at least a dozen WAPs advertising near my site. Late at night or early in the morning, the old WAP seems to work fairly well. During the day, it exhibits many of the failures we have all been observing. My working conclusion is that its radio is so bad that it cannot distinguish between radio signals, receives a continuous stream of garbage from the radio front end, and becomes hopelessly confused.
If so, this is a problem Cisco likely cannot fix with an update. It would require a recall. They have probably sold enough of these WAP910Ns that they cannot afford to, and will not admit to, a design flaw and intiate a recall
The Cisco specs say nothing about working in a congested radio environment so another way to look at it might be that this WAP will work just fine if you use it in the middle of Wyoming and the closest competing WAP is 10 miles away. So take it back, get your money back, buy better product, or move to Wyoming ;-)
