I bought this printer about 3-4 months ago. We have 3 wireless laptops hooked up to this printer. All 3 have worked great till about a week ago. Now, only 1 laptop works well on it, but now ,the other 2 will not even say that they have found the printer. I have deleted the softwear 2 times now and reinstalled it on both laptops, unplugged the printer, pulled the power box that attaches to the power cord out, but nothing seems to rehook up those two laptops, the 1 laptop is still working great? Also, when I hook up a USB cord from the not working laptops to the printer, it says that their is not a wireless router installed on this printer...even though the 1 laptop is still wirelessly hooked up to this printer and working just fine???
