Jeez, no need for that.
I do understand, it’s just that I don’t see the point in them having to equip the printer with the latest and greatest Wifi tech. Sure it would be nice to have the latest security features and all that but it is what it is.

I literally explained it up thread, so why are you ignoring the explanation?
Why are you ignoring that many other users (not just me) have issues with this?
I even pointed out that they don’t need the “latest and greatest” - using AX (wifi 6) rather than Wifi 7 would have been fine. Not that a single stream wifi 7 cheap is meaningfully more expensive than a single stream wifi 6 chip - and the price increase over a wifi 4 chip is pennies for either.
Do you live in a rural area and have no understanding of how much noise there is on wifi in cities?
Why can’t you accept that “just because you don’t experience the problem doesn’t mean it isn’t a problem”?
Tl;dr the wifi chip in this printer is unacceptable for the price. Do better Bambu.

I have done this and iot made no difference. I have actually tried 2 different dongles that were recommended on the Qidi FB group. I now have my H2D and guess what? it just worked, wifi and all.
I have been using, modifying, and building 3D printers since 2012 (sailfish was the OS back then) and the Qidi reminds me of printers i had before the Prusa mk3 changed the game and just worked.
My Qidi plus 4 will be sold now i have the H2D and i wonlt be buying from Qidi again
I honestly dont mind that its on a 2.4ghz wifi and where I do agree a better one would be much better my main issue is that even on 2.4ghz wifi my A1 gets maybe two bars with the router about 20-25 feet away, I can use other devices in the same area as my printer and get full signal on the 2.4ghz wifi.
That’s true and all but with these things, a large part of the issue is that having such an old chip using such an old Wi-Fi standard introduces things like interference, it’s extremely unreliable and there’s a reason why we moved on from those older protocols… they could greatly improve the reliability and the speed of these units by putting in a more up-to-date Wi-Fi chip! The one that they’re using came out in 2016, and that was a rip off of an old Intel Wi-Fi chip from 2007!!! A few things that come from China are of pretty decent quality, but when it comes to microelectronics, they absolutely suck because they use poor quality copies of old components… Some of these components are actually salvaged from old equipment!
That’s literally 3/4 of the stuff that they sell in the markets in Shenzhen!!!
This makes me think of stories from back in the '70s and '80s when the Soviets were trying to one up Rolls-Royce!
It resulted in terrible quality rip-offs…
They may not need the latest and greatest, but it helps… we aren’t strictly asking for extreme speeds, we’re just asking for better reliability and having the ability to use other Wi-Fi bands would greatly improve it… again, it’s not purely about speed!
Heck, a microwave oven 50 ft away is enough to disrupt the Wi-Fi on these things… It results in a tremendous amount of lost packets, and if it works at all, it takes forever to do anything… you might as well forget about using the live view on the internal camera… I could probably draw the picture faster than the thing could upload the live feed.
It’s pathetic.
Dude just drop it you literally won’t stop while demanding others agree with you. Just move on, nothing you can do about it at this point. Either use the product or MOVE ON and get another product that meets the specs you want. Just do one or the other. This is ignorant you haven’t brought anything other than crying about people not caring about what you care about. Move on, you are using a Chinese product that sends data constantly and you are worried about Wifi secuirity

C’mon dude… everyone is entitled to their opinion… yes, even you!
I have to agree with the “just because it works for you, don’t mean it isn’t a problem for others” sentiment that was expressed in this thread at some point. I live in a rural/residential area, where the WiFi networks of nearest neighours are barely detectable… so have zero issues with RF congestion. However, I can appreciate that in a urban area, that with the 2.4Ghz band basically unusable for some people, that failure to include at minimum a wifi chipset that supports 5.8Ghz WiFi, in a not inexpensive 2025 machine where WiFi is the primary interface, is a major oversight. i.e. the ESP32-C5 (supporting the WiFi 6 standard) entered mass production in April this year (although it was announced in 2022), if they wanted to stay with Espressif.
But hey, if it works fine for you, great. I for one don’t think the H2D only supporting 802.11 a/b/g/n is good enough for a premium machine… and for some users/network environments, is reason enough to avoid it.

H2D does support 5GHz wifi.

You are correct however the OP is not just giving an opinion but being rude and completely disrespectful to anyone that disagrees with them. Point is make a point no one has to agree and move on but being rude and continuing to accuse others of being ignorant and OP as being smart based on this subject is NOT needed. A simple agree to disagree is easy to do, didn’t need to do all what they have done. There are posters even citing forum rules and the argument continues.

Ok, I was thinking to myself “I don’t think I’m crazy” remembering setting mine, under my 5ghz band. But I was excited, and it went so fast.
I was thinking, as I read through this, that maybe I was mistaken…
Indeed… my mistake… I forgot that that 802.11n was the first to support 5Ghz WiFi… had 802.11ac stuck in my head for some reason. It would be nice if it was made clearer in the specs list though, as not everyone knows the WiFi/IEEE standards by heart! 
True… but it also takes two, and “don’t feed the troll” exists for a reason … 
… better to not keep provoking/inflaming the issue 
HD Camera feed…not sending much data! Really?
We have our 3 printers only a few meters away from a wifi AP with one wall in the way and only the printer closet to the AP has an ok connection. Wifi6 is not hard, Ive made some home made ESP32 smarthome sensors with wifi6, surely the Bambu Labs team could have managed!
The printer itself is awesome, but I agree, it’s networking is UTTER RUBBISH!
It’s more likely due to the antenna placement instead of other things. BBL always choose the worst possible place to put that weak antenna. E.g., for X1C and P1S they put the antenna inside the frame and it’s just a very weak pcb antenna.
This is where it is on H2D.
What I’ve noticed in LAN Only mode (as well as Cloud mode) is that the printer WILL NOT CONNECT or MAINTAIN A DHCP IP ADDRESS if it can not get out to the internet. (Which is doesn’t need to do. Heck it doesn’t need to ping the gateway either…) It’s a really odd thing. Specifically, even on LAN Only mode the printer will refuse to keep an IP address if it can’t try get to certain places like e.bambulad.com… but it’s also trying to get to:
…and that list rotates almost continuously every 5 minutes.
I have the printer blocked at the main firewall by IP and MAC. I also have the network configured to prevent the printer from talking to anything on the same network wirelessly. (It can get to other devices on the physical network, just not play with other wireless devices… and given that it’s on an IoT network, well, you don’t want any of those devices to cross contaminate other devices with their almost non-existent firmware/security updates… especially your $3500 H2D.)
I’d be willing to pay really money for a physical network jack for my H2D…
…and for them to fix the either intention attempts to have a printer in “LAN Only” mode stop trying to send out some form of telemetry.

This is crazy! My printer always showed low signal even though I have a WiFi 7 on the same room. Now I understood its connecting to a router that is 2 rooms apart and has legacy network configured.
If they have an old chip which means even a firmware upgrade cannot solve this.
WTF why my PRINTER is trying to connect to random irrelevant websites and companies like Apple and Microsoft. Bambu, you have to explain yourselves.
it’s not trying to send out telemetry. it’s trying to synchronize it’s time

based on the fact that pool.ntp.org is in there, it’s trying to use their time servers to sync it’s time
