“The fix is to set the ip reserved for your printer.”
Great! But - how do we do this? 
Pretty savvy but I don’t think I’ve seen setting that sound like this for my gateway. It’s a fairly new model.
FWIW I’ve already renamed the 2.4ghz band.
@knightrdr2004 - any help appreciated! See my previous question. Thx
I’ve been having this issue for a year now. It’s honestly unreal that bambu has such a great printer with such terrible software. PLEASE FIX THIS BAMBU, it’s not acceptable. I have no idea exactly what fixes it, but my method that works sometimes is to factory reset the printer, remove the bambu app, go into bluetooth settings on my phone and forget the printer, then go through the whole setup process again. This does not always work, but does more often than not. Unfortunately there is no rhyme or reason as to how long this lasts. Sometimes its until the next time I turn the printer off, sometimes it’s a week. Needless to say, using this printer has become a total chore and ruins what is otherwise a great printer.

Same issue. Lost connection last night and instead of troubleshooting it I figured i’d just disconnect from the internet and reconnect. Big mistake, haven’t had any issues or changes in over a year, and now NOTHING. Just incorrect password, which it isn’t. Be better Bambu, your product is too good to let something like this brick a device.
Same here, my P1S cannot comnect to the wifi since 4 months now, and after months of extremely sloppy customer “service”, and following the logs, for the bambu support team it was a problem with the wifi cable, which they promised to send me a replacemet, but made a mistake and sent me a totally unrelated item. I am so tired of this issue and their shitty response times and low effort solutions that i am focusing now on my new Qidi Q1 Pro, and as it is completeley open, with no risks of intellectual data theft, as it does not require a cloud (anothers person computer) to fuction properly. Yes I can confirm the Q1 is a great machine and, comparable to the P1S with added bonus of a 60C. heated chamber, and an easy to service 350C. inox-tungsten nozzle (optional). So boo bye bambu, it was nice to meet you but i will build my 3d printing farm with your upcoming competitors, not with you. Thank you!
Same problem with me. My printer randomly just stopped connecting, disconnected from wifi wouldn’t connect, factory reset wouldn’t connect. Says wifi password is incorrect (it is). My IP on printer is 00000. Anyone figure it out?
Just had this issue. Some of the responses is correct but leaves out things. Once you split your networks change the name to the 2.4 one.
this video on youtube helped me but the interface is different. Search for ( How To: Xfinity Wi-Fi Splitting Tutorial (Split 2.4GHz - 5GHz) Comcast Fix 2022 
)
you may need to type in the password 3 times but it eventually took it and the printer is back online.
I had same issue. What worked for me was to keep retrying my password. Third time was the charm for me. Hope this helps.
Changing the channel on my router worked for me. Am investigating reseriving the IP address. I can separately set SSIDs for my 2.4 and 5 GHz networks.
