I recently replaced my tablet from iPad4 to Samsung Galaxy 4 and phone from Samsung Duos to the latest BLU. Both upgraded automatically to Lollipop. In the same network I have a powerful desktop, an HP laptop, both running Windows 7 Ultimate, both connected via 10BaseT cables. I also have a Panasonic Rough Box with Windows 7 Ultimate connected wireless. The printer, also connected wireless is HP 6830. My replaced devices had no problem connecting, and the replacements worked fine while running Android 4.4. I probably screwed up some setting in Lollipop, but I'm utterly frustrated. HELP!!!
