Guys, guys,
This is driving me to distraction. My 64Gb PB, running 2.1.0.1753 op system, is refusing to find or keep connection. Even if I have a saved wifi point, I get either minimal or no signal when I try to connect. My laptop, my other half's laptop and her iPad (excuse the language) also have full signal.
I would rather not do a complete system reset unless really necessary so, if there are any ideas out there...
