Cannot get 3D printer to maintain LAN wifi connection when powering up(hit and miss)

[Chock Full o Nuts]

Getting irritating. Recently upgraded to a Creality K1C printer, and at first, found on my network and connected just fine.
Happy with unit, but not the wifi.

Have searched and searched, tried 'solutions',... sometimes connect, most times not.(seems this an issue for many)

Have T-Mobile internet with Google mesh wifi system, so could use the T-mobile or the Google connection, and have.
Both support 2.4 and 5 ghz, and printer states it goes over the 2.4.

No issues if connecting through Creality Cloud to phone or tablet, but local wifi to PC, nada.

Tried DHCP reservations within router, static IP(PC and unit on same connection, and scan or manually add through Creality software-not found), restart both and make connections in different orders, factory reset unit, firewall....

Any ideas on something I may be missing? Can't sort this, it will be going back and exchanged for something else.

We had an issue with ours (I forget which Flashforge it is off the top of my head) and it needed a firmware update?

Once we did that, it has been better about staying connected to wifi.

Maybe something to check?


Sorry can’t be more helpful…still learning

Latest installed from start or shortly after. Some have said they reverted to previous firmware with success, but have had a few weeks and established connection just 2-3 days ago. So not thinking it's that.

As a experiment can you get to your T-mobile router and temporarily turn off your 5 GHz WiFi line?

Have tried to look for such in both 'networks', but no.
Info says TM and Google broadcast both simultaneously and your device will catch the one it is suited to.

I was going to suggest something along this line.

I have devices on my network that use 2.4. Some don't have a problem connecting, but others won't connect at all (not hit or miss) if both 2.4 and 5 are enabled on my router. When that happens, I go into the router settings, disable the 5 ghz, then I can connect the 2.4 device. After that, I'll go back into the router and re-enable 5 ghz and everything works as it should.

But, since the OP says it's hit or miss I don't know if that'll be a good solution to his problem.

Oh, I just thought of another possibility.

When you installed the drivers/software for your new printer, did you completely uninstall the drivers/software for your old printer? If you didn't, you could be running into conflicts.

I too have had so much trouble with 2.4 only devices. I've done the same thing. All cheap WiFi gadgets are always 2.4 only. The OP sounds like it might be a distance/location thing but he's got one of these mesh things which I don't have. I would suggest that he turn off goggle mesh and see how that works but there's a point where the 'cure' is worse than the symptoms and the rest of your network quits working.

I do not know about 3D printers, but I would never use Wi-Fi with my CNC machine.

Going to have to check. Slicer software for old one had wifi capability but never attempted to use wifi after I had TM/Google setup. Was wonky.
Just transferred file through SD card.

Definitely not a signal issue. Strong network through home, full bars PC and printer.

BTW TM router is hard wired to main Google mesh node, so I essentially have 2 totally separate wifi 'spots'. I can connect to either one on any device with good signal/speed.

I would hardwire back to my main, but they didn't give me a freakin jack!

Cheap bastards.

Well, got connected. Restarted network(which had done before-but guess something along the way didn't go right.)

Will see if it holds. Not counting on it. Thanks all.

Same shit, cycle all. On the 'cutting edge'?
Guess you're not getting my data if you can't lock in a reliable wifi connection between 2 local devices. POS is going back.
