adding a 2.4ghz network with WPA security worked for me. unbelievable that a printer now cant use wpa2. fix this ASAP
So I have my P1S on 2.4GHz and my PC is on 5GHz (different SSID) and they talk fine, I am LAN only (set up was a pain, nothing, name-no-ip, then name & IP). I do have a reserved IP associated to the MAC of my printer and I am WPA2-personnal only… So far my printer has never lost wi-fi even after router power rolls. I don’t use Handy and my printer has never had a QR scanned or been used anyway but LAN only and I power it off when not in use.
I had the same issue. I have Google Nest WiFi and what worked for me instantly was I went into my router through the Google Home app and setup a DHCP reservation using the MAC address of the printer and assigning an IP address that isn’t already used on my network. You can get this my tapping the top of the wifi screen on the printer. Before you choose an IP address I would recommend looking at the device list on your router or trying to ping the IP address you want to assign to make sure its not in use to avoid an IP address conflict.
I had a wifi problem with my Bambu Lab A1 device. When I shared the internet from my phone and computer, it was connecting without any problems. The security protocol in the modem settings was set to WPA-PSK. I changed it to WPA2-PSK and the problem was solved and now it connects without any problems.
Agreed !
I also get intermittant connection on my Bambu X1C. Cant point a reason for it!
I made a separate thread, but I also wanted to reply here for people following this thread. I’ve found some router settings that have solved my P1S connection problem.
On my TP-Link router, I’ve disabled MU-MIMO and set the channel width to 20/40 MHz. Now, when I turn on the printer, it connects to wifi immediately. Here are my full settings:
In this screenshot, I had disabled 802.11ax, but I’ve re-enabled it since, and it works fine.
EDIT: I’ve had a support ticket open with Bambu almost since I bought my printer. Two weeks ago, they sent me a new AP board for my P1S. Since installing it, I have had no connection issues. The version number printed on the new board was higher than the one I removed. I’m not sure if that’s the reason it’s improved, or if the old one was just faulty.
I’ve returned my router’s settings to the more desired settings. (MU-MIMO enabled, 20 MHz channel width.)
i can point a reason to it. the wifi antenna is bad, and the wifi technology is ancient
rig an external antenna with good gain
don’t ever allow 40Mhz channels on 2.4Ghz, MU-MIMO isn’t the cause of the problem (it’s enabled on my APs fine).
I think you mean MU-MIMO isn’t the cause of your problem. Disabling it solved mine.
the only way that would work is if your AP’s firmware had a bug and it didn’t implement MU-MIMO correctly (or failback to OFDMA for non-MIMO devices like a wireless-n device)
I don’t really care why it works. I’m satisfied that it does work.
i do care why it works, but that’s because it’s my area of expertise.
advising other users to turn that off who don’t have the same model of AP as you can destroy their network performance for no reason.
