HP c309g cannot find wifi networks

my hp photo smart premium c309g all in one printer disconnected from the network the other day.
all attempts to reconnect it have failed and I'm wondering what the issue could be and how to fix it.

The wifi led is on.

The wifi icon on the printer's touchscreen shows that wifi is enabled (but no signal)

searching for (or manually trying to connect) a network yields nothing. in fact it sits on the "searching for networks" and eventually times out. There are neighbouring wifi networks that would be detected and none are now showing up.

The printer has not moved. The kids have been using the photocopying function so no idea if they've done something?

The printer works fine is all of its functions side from wifi.

i know i could use wifi or powerline adapters etc but this question isn't about that. ultimately i just want to feel confident pulling it apart and seeing if the wifi module is stuffed or its just an aerial unplugged etc.

You can try a factory reset as described in this link:

Unplug the printer from power. Hold down # and 3, 6 or 9 (for different levels of reset). Plug the printer in and keep holding the buttons for 10 seconds longer. Try the "#3" version first.

WiFi signal strength can be affected by lots of things, even if you have not moved anything - or think you haven't. And printers are not as forgiving of dropouts as PCs or phones are. If you put your phone on the printer, how good is the WiFi signal your phone sees? I know you can't really compare 2 devices, but if neither of them sees a decent signal than you will most likely have problems.

Alternatively, try taking the printer to another room. If it sees WiFi there, then again you know the problem is location.

ah yes, I did mean to say that I'd already done the factory reset with no luck but thank you as I also thought that would've sorted it out.

I'll try what you've suggested re the location... i know what they say about assuming something (ass-u-me) LOL.  I have 2 laptops in the same room as the printer that find the wifi networks without issue.  My phone also picks up the signal fine.  Using a Wifi signal app, the signal is -52dB in the room, which according to the app is in the acceptable "green" range.

I'll report back and  thanks again for your help

One thing that comes to mind is the type of security that the wifi uses... e.g. WPA/WPA2 as well as TKIP / CCMP and whether that would affect it?  I'm using WPA encryption with both WPA (TKIP) and WPA2 (CCMP) modes enabled.  Don't want to send you down the garden path on this one but thought it might be worth mentioning.
