A1 Won't Connect to Bambu, X1E Does

My A1 is unable to connect to Bambu, yet my X1E does just fine and support has only answered with a generic response in 4 days, despite my daily updates.

If you log out it wont log back in; have to use another phones hot spot and not on Verizon to re-sign in.

I have Comcast business class in the house. Printer is over 575 hours of print time and no network changes. Sometimes after hotspoting on non Verizon, it will show up for a limited time when back on my house WiFi. Oddly, it will let you push a file to it, the screen on the printer will show 100% download, hang for a minute then Bambu Studio will tell you it failed to download and it dissapears off the printer.

I have done the usual troubleshooting like:

  1. Changing wifi APs
  2. Factory resetting
  3. Manual firmware reinstall
  4. Ran though my network settings.
  5. Signing in and out of apps and devices.
  6. Changed SD cards.
  7. Cussed at it.
  8. Time.
  9. Built scripts to ping based off their wiki (global not CN mainland), has some fails: PasteBin of the Ping results. If you could make and run the .bat and post your results; source is available here: PasteBin BambuPing.bat . Post the log in pastebin and link it back for me and possibly others to compare to in future troubleshooting.
  10. Disabled some of my network securities
  11. IP hopped both public and privet ranges.
  12. Different computers
  13. Occasionally some computers can access it in lan mode, but that defeats the purpose.

I am confused as to wye the X1E on the exact same wifi and thought the exact same network works fine all day long but the A1 plays deaf. Support has not been there to support, so I am up for some community ideas to try. Also it appears I can not set a manual IP address in the A1, is this correct?

Should also note; my network is not a standard residential. It is more of an “enterprise” network with several public facing static IPs, some servers, its own public and privet DNS, DHCP, among other things with various automated securities that for obvious reasons you would not disclose on a public form.

It has not had any changes since A1 was purchased and this just happened out of the blue about 4 days ago. Test configs the bypass the securities also had no effect.

The antenna in the A1 seems lack luster, so borrowing the neighbors WiFi to test is likely out of the question. Also the printers are within 10 feet of an AP and it still doesn’t change the issue.

Also my different WiFi bands have distinct names and locks so it wont do that weird multiband hopping some do. I do not yet have access to fiber at the house, but maybe this year they will finish running the stringers so I can be hooked up.
