Kobo Arc - WIFI Connection poor

[stevemce]

Hi All,
I have WIFI connection problem with my Kobo Arc,
the WIFI connection was fine for the first few weeks I had the device.
However in the last couple of weeks, I can only get a connection when I am very close to the router, and I mean *very* close < 30cm. Right up against the Router in fact.
The Connection drops when I walk a couple of meters to the other side of the room.

I have tried upgrading to the latest Software, deleting and re-creating the WIFI connection settings. and various re-boots.

Anything recommendations?
I want to try a Reset of some kind - any advice?
I have some games installed - which I don't want to lose. No books installed.

I've read about 'paperclip resets' on the forum and the reset under 'Settings', can I reset without losing my games (or how do I backup first?)

What is my best course of action here?
TIA
Steve
