HP MFP M140 w suddenly won't stay connected to wifi

[captjaneway4]

Hi there - no problems with this printer for months and now suddenly it will no longer stay connected to wifi. The only way to get it to print is to unplug it, it briefly connects when it comes back on but within a few minutes the signal is off and it is showing the ! mark. Also the factory reset sequence of pressing the wifi symbol and the x simultaneously doesn't work. Is this a mechanical fault? 

I've tried removing the printer altogether and re-adding it, but it won't allow me to do that as I'm an instant ink and instant paper subscriber (aka I'm a good customer pls help me). If I have to do this I will but I'd rather not have to go through cancelling and setting up my instant ink account if I can help it. 

Any advice appreciated.
