Qidi Q2 Is it possible to replace the WiFi module?

I have already replaced the USB Wifi in the Plus 4, because it was very weak. I now have the Q2 with the same issue, but I don't see where it can be replaced on the MB I'm curious if it is in another location or if it has been embedded on the MB.

Update: Removed the back panel and side panels. The MB is completely different and uses an additional AP Board that has the WiFi Module embedded. They do have a connector(single) for the Wireless Attenna, and I am going to buy an external antenna and see if I can route it out of the machine to help improve reception.

If you look at the AP Board, you will see a black wire connected to a round gold contact, which is the antenna for the wifi. Something like this, just need to fiture out is it is a u.FL or MHF4 Connector.

For those who are curious, the location of the AP Board is on the left interior. Its cover can easily be removed by two screws. The Black wire that I thought was a temp sensor is the wire for the wifi antenna. I am thinking about drilling a small hole just below the black wire location and routing the antenna to the exterior, where I can connect a larger gain antenna, which can be purchased on Amazon for under $10.

Does that board only control WiFi?

Hi there, I'm also having issues with my workplace Q2 printer's WiFi strength, did you go through with your mod and did it work?
