Does anyone have a solution to the - "Robot Offline" issue

As of a week ago I can no longer connect to my D3 robot, I have tried multiple solutions.

1) Making sure I have a 2.4Ghz connection available

2) Reset the robot completely and started it fresh

3) Connect to the robot using perscribed method of holding right hand side and powering off, then powering on again

4) I can connect to the robot however once connected I can't detect any wifi connections to link the Robot to

5) 10-20 times attempted the same thing, it's the same result regardless.

Any help would be appreciated - I want to set some parameters for the clean zone so it doesn't try and vaccum a table bottom and get stuck every time.

Edit: I followed this process to update the firmware (yes unfortunately it seems the reason that it may lose connectivity / wifi access may be due to outdated firmware. So for those tech savvy and willing give this a go:
