Just purchased a Ender 3 V3 Plus and I am having some wifi issues. I am getting an insanely crappy connection. I have the printer right next to my access point and it is the only thing on the access point. I have updated my firmware and still having issues. I also can not view my nebula camera. 3d printer keeps dropping connection constantly.
I have heard that some people have issues when their router is running 5ghz bands. Try disabling that band and running on 2.4ghz to see if it stabilizes.
If that’s the case that’s disappointing. I will have to give it a shot. Thank you for the information. I’ll reply back after with results.
This did not fix the issue sadly.
Your problems may be antenna related. If not done already, open the bottom plate and check so that the antenna cable/connector is properly connected to the main board. Refer to main board drawing in the manual. The connector on the main board is placed next to the filament run out connector. The antenna cable is quite long and the antenna is placed under the front plastic housing where the Y-rods are attached.

Thank you, I ordered a new wifi router and have not had any issues since.
Hi everyone,
I’ve been struggling with my Ender-3 V3 KE and its Wi-Fi connection. It behaves strangely:
It can see all my neighbor’s networks (TV, refrigerator, etc.), but it can’t find my own Wi-Fi.
I run both 2.4 GHz and 5 GHz, but of course the printer should only use 2.4 GHz.
At one point, it even detected my phone hotspot last night, but now it doesn’t.
I tried everything: changing encryption (with/without password), resetting the modem, different SSIDs, etc.
After digging into my router settings and reading community advice, here’s what finally made it work:
My working config:
Band: 2.4 GHz (B+G+N)
Channel Width: 20 MHz
Channel Number: Manual → 6 (instead of Auto)
Regdomain: US (instead of Russian/Auto)
Security: WPA2-PSK (AES only) (no WPA3, no TKIP)
SSID: short + si
mple (letters/numbers only)
