I have a desktop that is wired to my router, and two laptops that are connected wirelessly. From my desktop I can open documents on either laptop, edit them, and save them without any issues. However, I am having problems when I open a document on laptop A from laptop B. I can edit it, but can't save it back to the other laptop without renaming it.
I've tried going back into the documents folder of each laptop, and setting it to allow all homegroup users to edit and save. That works for a day or two, and then it reverts back to having issues. This is only on the laptops using wireless.
Windows 8 on all computers, and the router is a Netgear WNDR4500.
I've tried running the Homegroup trouble shooter to no avail.
