This is ridiculous. My P1102W printer worked flawlessly until a firmware update last year. Now, it does not retain wireless credentials over a reset or sleep, making it useful only as a direct connect USB printer. Countless other posts have described this problem, and the responses always point to the page showing how to configure the wireless credentials (which we have done countless times) or refer to a firmware update which, like this one, DOES NOT FIX THE PROBLEM.
We are not idiots. We know how to configure the printer. We also know that this is a real and serious bug in the P1102W firmware which should be resolved. If it cannot be resolved, then post the original firmware so we can revert our printers back to something that works.
I have been holding off replacing the printer, in the hope that this problem will be resolved, but it looks like I will need to replace it in order to actually have a wireless printing capability. And if so, it certainly will not say HP on it.
