Hi Stephen,
You bring up a good question, so let me give some background. [Stephen is referring to the fact that many of our newer AP's require at least version 9.5.1 and in some cases 9.6.0)
Back in January we had made the decision to move to 9.5.0 for the factory build (i.e. what we ship).
Unfortunately, and unknown to us at the time, this introduced a problem into the ZD1100 products (something related to the USB subsystem) - and essentially they all had to be RMA'd - there was no practical field fix. This is related to the warnings you now see when downloading ZD1100 updates (9.5 and above). This particular problem only showed up in "factory built" 9.5.0 units.
So we reverted to 9.4 at the factory while we investigated the root cause of the USB issue. We now know the cause, but that took a while to fully characterize even with our best engineers working on it. We did not want to jump to any newer release in the factory until we had that understanding.
We are in the process now of making 9.6.1 the factory build. That will be done on our side fairly soon, but it will take a while for inventory in the distribution channel to reflect that (probably at least a month).
There were a few other challenges thrown in that contributed to the delay in getting the newer code into the factory.
We do sincerely apologize for the extra work this causes everyone. We are definitely looking at all the things we need to change to avoid or mitigate this in the future. For example:
- All AP Install Guides now come with an explicit warning about the minimum software version required
- We developed a method for customers to quickly and easily get access to software downloads via warranty registration
- We've changed our factory QA processes to ensure we won't see a repeat of the 9.5 issue
- We've created KB articles explaining the error messages that appear when using a new AP with downrev software
- We intend that the first maintenance release (aka the .1 version) of each release will generally be used as our factory build in the future.
I hope this helps explain the present situation and what we're doing to fix it. We do appreciate that this hasn't been our best showing in terms of product quality but the whole company is focused on improving that.
-Keith
