It’s hard to imagine any router now days that can NOT handle both 2.4 and 5Ghz on a network.
I bet if you ran a “Net Watcher” it would tell you that the IP address for your 3D printer was assigned by your router to another device. That was happening to me. I started a ticket on being able to specify an IP address for the Bambu printer, but they closed it and said it can be done in the router using a MAC Address table. That’s fine if you have access to your router. I don’t as it’s supplied by my ISP and appears to be locked. I got around it by resetting (power off/on) my router and turning on the devises in MY priority of use. That seems to have worked.
Oh yeah, the same thing happened to my Brother Laser printer. Resetting the router then turning on my PC, PC devices then all the rest of the house devices seemed to work again. Also take note that most new TVs and Direct TV devices are terrible at skipping around and grabbing IP addresses. My TV allowed me to set an IP address, so I set it up really high. Like 205 or the like.
I will say this is almost certainly just a faulty unit. I have also ordered a Bambu X1C as my first printer, so am entirely unfamiliar with manually dialing in a printer; and I’ve had none of these issues. I’ve actually not had any issues at all. Not that this makes your situation any better, but more just to suggest that you should keep pushing to try to get this issue resolved and not hold it against all X1Cs because mine has 70 print hours in less than a week and I have only had 1 failed print due to me switching nozzles without updating the settings in BS.
I had issues with BL support so I hear you. But apparently they offered you an advance replacement? OMG I totally would’ve jumped at that (I even begged them for it, and they didn’t give me that choice at the time).
Based on the fact that a year later they’re now offering advance replacements, I have to say I’m impressed at how BL is listening to their customers.
You should never have a combined network name, many IoT devices won’t play nice with that. You won’t notice when it’s a light bulb because it’s not transmitting/receiving lots of data, but when it’s a device that does that, you will definitely learn the hard way why it’s not a good idea to use different bands with the same network name. This is not cellular networking.
The fact that you only noticed that TPU is not printable from the AMS is your own fault, own up to that, including it in your complaint just shows you are clueless as a person. Who spends “$3k” on anything without researching!?
Please sell your X1C and buy that garbage Prusa. You deserve it. And then you’ll learn how awful their support is and maybe you’ll appreciate what BL has made a little bit more.
I have to agree about the AMS though. It’s a badly designed product, with no active heating, no support for many third party filaments, can’t deal with cardboard spools (which is the majority nowadays) without hacks, and unfortunately BL insists on locking down the RFID which is ridiculous for a fully-priced accessory that’s mostly plastic. The Hydra AMS mod proves that the AMS can be 3D printed… those little PCBs and the motor, the little wiring inside it and the bit of firmware just doesn’t justify the £349 I paid for each unit (I have 2 units) to then have locked down RFID (which I knew before purchase, but it makes no sense as BL can’t supply all colors and different filaments existing out there). I have hope that they’ll stop locking down the RFID function and allow users to buy and use their own NFC tags in their own spools, writing the info from Bambu Studio as a custom filament.
So there you go, I agree with one thing you’ve said
