Been over a year now.
I want to be able to work on a project, and print it. At this rate might as well go back to my Ender3D. At least it would just fail on the print
Oh, we all feel your pain, and trust me, you’re far from alone. This issue has been raised over and over, but Bambu’s silence and lack of action make it crystal clear they don’t care. It’s like they handed the network protocol stack to a Junior Varsity team and left the community to figure it out with zero tools for self-diagnosis.
Submit a support ticket, and you’ll get the same canned response: “Send us your logs.” Then? Nothing. No solutions, no follow-up, no accountability.
The real insult here is Bambu’s refusal to give users access to undecrypted logs. This could be the key to solving these connectivity issues ourselves, yet they withhold it. Why? What are they so desperate to hide? Meanwhile, almost every other network device out there offers diagnostic tools, but not Bambu.
And then there’s the elephant in the room: the need for a wired connection. USB, LAN—anything! Their insistence on being Wi-Fi-only is absurd, especially when their solution is so fragile. If they want to act like they’re the “Apple of printers,” they need to deliver something that actually works seamlessly or back it up with Apple-level customer support. Spoiler alert: They do neither.
Now, having shared your frustration, let me offer a couple of workarounds that work for me about 80% of the time:
Yes, both solutions are a pain in the ass, but in the absence of real support from Bambu, these are proven fixes. Oh, and don’t forget: you’ll also need a healthy dose of luck and maybe a small animal sacrifice to the Wi-Fi gods. 
Is that still a go to? valium is cheaper… 
I have an X1C and a netgear mesh router network and no problems at all.
I have a X1E on my work, that one has a LAN connection option but also wireless it worked fine (also in full LAN only mode, so no cloud involved).
What does the network connection test says? Maybe try to put it closer to your router and don’t use repeaters. Also make sure both use the same user acount, the printer can be connected to one user at the same time (I also had in the past the problem that I had accidentally created 2 accounts, one with password and email, and one used with the google login option).
Dumb request, but I am looking fondly at my Ender 3D with its USB port. Is there a direct connection solution to printing to Bambu X1 Carbon?
My Bambu is at home, the Eero mesh router node is right beside it, and my computer is 3 feet from it.
There is nothing strange with my setup, its the most straightforward wifi set up ever
Use a dedicated 2.4GHz Wi-Fi SSID
Ah thanks for this. I am not sure if I can do this, but I might go by a router just to get around these utterly insane issues
don’t use repeaters
As much as I like the Bambu printer when it actually works, doing major construction rearranging my entire house just so I can do 3D prints is sadly not a realistic option
PS. Yesterday after wasting hours trying to get LAN to work, I re-enabled Cloud and it took 45 minutes to send a STL model that is 2 MB in size.
There’s a special board that a guy here is starting manufacture of that has an actual hardware ethernet port. Funding for one more week so should be available “soonish”.

Ok then… the plot thickens. Had you mentioned that at the start, I could have saved you some time—I also have an EERO router.
Put simply, if Bambu Lab is the villain in this Wi-Fi melodrama, playing the role of Saddam Hussein, then EERO is the equivalent of a certain infamous German mustachioed authoritarian from mid-20th century Europe. 
Here’s the problem: the EERO mesh router sucks. There’s no sugarcoating it. It is absolutely the worst of the worst, and this is coming from someone who has used hundreds of Wi-Fi products while working in the industry that builds them over the last 25 years. EERO is the scum of the earth, serving only one purpose: to provide the bare minimum so Amazon can spy on you. I plan on replacing mine soon.
In the meantime, while you look for a better router (which is the only long-term solution to that piece of junk), here’s what you can do:
EERO has a hidden feature for temporarily disabling the 5GHz signal, allowing for a 2.4GHz-only connection. If you didn’t know about this, you’re not alone—Amazon buried it in the firmware and barely mentioned it. Note that this feature may not yet be available if your ISP hasn’t upgraded your version.
If you’ve fallen for the “Mesh router” marketing hype from your ISP and have more than one router active, disabuse yourself of that notion immediately. Mesh routers are buggy, and EERO’s implementation is about as good as Bambu Lab’s grasp of TCP/IP—utterly terrible.
Disconnect any extra Wi-Fi routers. Use only one unless you live in a 5,000-square-foot mansion. Multiple routers often interfere with each other, causing signal issues. Bambu printers have proven they can’t handle this chaos.
Go into the troubleshooting menu on the EERO App on your phone and temporarily disable 5GHz. Follow these steps(Android example):
Once your EERO is the only router broadcasting and set to 2.4GHz only, you should try a new connection from your printer. You may experience a more stable connection. It’s not perfect—far from it—but it’s better than nothing until you can buy a real router from a real company. Not Amazon.
If it’s not already obvious, on my personal “love scale” for tech companies (10 being the best), Bambu scores a 2.5, Apple a 3.1, and EERO a 1.9. 
All three are tech bullies that refuse to listen to their customers. The only saving grace for Apple? At least their stuff works.
And I bet you thought you were getting a great deal when your ISP offered you that “EERO Bundle,” didn’t you? 
My second EERO router has been unplugged and collecting dust since about a month after I started my service two years ago, even though my ISP has upgraded my hardware twice since then. I live in a big house and my EERO Router is at the opposite end in the basement and is far more stable as a solitary compliance than it ever was when operating as a mesh.
After the first of the year, I’m defecting to a real network appliance maker and ditching EERO altogether. Read between the lines: I’m throwing away a completely free product and willingly spending money to buy my own hardware because EERO is just that bad. 
What an amazing reply, thanks !!
I guess I’ll have to disagree with you on the Eero? Absolutely nothing else that uses WIFI has had a problem with them. I’m talking electronics bought at electronic stores, appliances, weird bizarre electronic maker boards I’ve gotten from Alibaba, electronics that are barely in alpha stage used for R&D testing
Literally only Bambu has an issue with them, assuming that is the problem. And occasionally it will work fine, but then some random update will kill the connectivity.
I am not going to set my Eero to 2.4 Ghz for a test, destroying the connection to the utter myriad of other devices in our place, just to do a test. I will though try to find an old router kicking around to see if that makes Bambu printer happy
You might consider yourself fortunate, but many of EERO’s weaknesses stem from the same architectural flaws as those found in Bambu Labs. These issues may not be obvious if your device stays connected reliably, but the real test is what’s “under the hood.” Bambu struggles because it lacks core fundamentals—basic TCP/IP functions like setting a static IP, accessing log files, or even SSH support. EERO shares these same deficiencies and similarly forces users into a restrictive phone app for management. This isn’t about simplicity; it’s about user surveillance, which aligns perfectly with Amazon’s motivations for acquiring EERO.
Unlike every other network router I’ve encountered, EERO stubbornly refuses to provide a web or SSH management interface. This stonewalling has drawn consistent criticism, much like Bambu Labs’ refusal to address its shortcomings.
The real trouble starts when things go wrong. Pair a misbehaving printer with a misbehaving router that denies users meaningful management tools, and you’ve got a recipe for frustration. EERO’s shortcomings become painfully apparent when integrating numerous devices over time. In my work, I frequently connect new Wi-Fi devices to the EERO hub and have seen firsthand how poorly it handles troubleshooting. Unsurprisingly, the IT community has been vocal in its criticism.
And just like Bambu, EERO effectively gives its customers the middle finger. Some of my former colleagues now working with ISPs that use EERO as their primary appliance have shared similar frustrations. By the way, if you didn’t purchase your EERO device outright, it’s likely leased to your ISP. You’re ISP doesn’t actually own it, Amazon does. So, what’s in it for Amazon to provide “free” hardware? The answer is simple: Alexa and the surveillance services embedded within the router. These systems report back to Amazon on web browsing habits and IP resources such as streaming and what appliance are hooked up to your network—practices outlawed in other countries. Unethical? Absolutely. Illegal? Not in the U.S., apparently.
So if you have an rather unique IOT device that is uncommon such as let’s say a hypothetical toaster that fries eggs at the same time and you get a mysteries coupon pack in the mail with offers that seem to know everything about you, you can thank Alexa and EERO for reporting that information back to the mothership. And everyone though George Orwell was fiction.
Which mesh router do you recommend then? This doesn’t absolve Bambu, I am just asking what is a Good Citizen mesh router company
We need a mesh router with multiple nodes due to how our place is laid out
I honestly haven’t decided which router I’m going with, but I definitely won’t be choosing a mesh router. That technology just doesn’t suit my needs. I have a large house, but 2.4 GHz works fine for me as it provides good distance. The only spot where 5 GHz might be helpful is near my office, which is close enough to the basement where the router currently resides.
By the way, one of the problems with so-called “artsy” routers like the EERO is their attempt to disguise the technology as a sleek appliance for display. I call bullshit—it’s a tool, not a piece of furniture. I don’t care about aesthetics; give me functional, adjustable antennas that I can position for better coverage.
I should also admit that, back in the day when I worked for a company that made digital signage Wi-Fi appliances, I learned the value of directional antennas. While I no longer have a meter to measure precise signal strength and direction, there are still excellent free utilities for Android that allow for basic RF site surveys. You might want to check out YouTube for tips.
In my experience, I’ve yet to see a residential property that can’t be covered by a single access point. If you need more than one, it’s worth investigating what’s going wrong. Remember, standard 802.11AC has a 100-meter line-of-sight range. That’s nearly twice the length of the average home. So if one places the router in a central location, there really isn’t any justifications for a second access point, that is unless you have concrete or metal lined walls but for standard wood construction in the US, 100meters is more than enough.
I’ve been fighting this for a couple weeks now. The 2.4GHz trick you showed above doesn’t work for me. I still have to get my printer off the network and re-add it every time. It is aggravating.
