Hi,
I have a K1C which is borderline impossible to use via wifi. The wifi network is fine, I have many other devices that use it with no issue.
The symptoms are that when the device was new it worked reliably, then over time it occasionally fails to get on the wifi network with rebooted and this seems to get more and more common over time until it becomes effectively unusable.
I reported this to Creality support and to their credit they sent me a new mainboard, which I installed in a very stressful operation since the connectors on the mainboard are all delicate and absolutely buried in glue. This seemed to fix it and I thought everything was great, but now a few months later (I don’t use the printer a lot) its showing the same symptoms as the first one.
I power it on - it fails to join the network. I try forgetting the network and re-adding and most the time it claims there’s a password error (there is not). The delay before it claims there’s a password error varies - sometimes it’s pretty instant, other times it can take 30 seconds or more. It then fails to get an IP address via DHCP.
Other times, if it does join the network it will just sit there being very poorly connected. I can leave a ping running and it will drop 10s or hundreds of packets then reply to a couple, etc.
Anyone have any ideas, please? Can I really have got 2 defective mainboards in a row? Seems odd that they start off pretty reliable and get worse.
Thanks
