Router is a "Cox Panasonic" router, just the normal one they give out. I'm gonna have to make some sort of interim network for this to run on, but that's not an issue. Turns out once I replaced it with a MicroSD card set to the proper cluster size, it processes! Web interface froze on me once, but it's printing from a 70mb file right now, and I got it to at least start a 150mb file. Now back to battling my bed adhesion issues. Thank you everyone for your help!

I'm unsure of what the errors say each time it fails on upload. Is there a way to check them? I'll go to upload a file and it'll either load one percent, hang, then display "ERROR" across the loading bar, or it'll load a little bit, then just display "ERROR" on the bar. Sd card 2 is the original. I have more I'll try now that I know the other known good one, is not good due to the cluster size.

EDIT: Tried with 3rd Microsd card, M39 report of:
SD card in slot 0: capacity 7.99Gb, free space 7.95Gb, speed 20.00MBytes/sec, cluster size 64kb
3rd microsd card let me upload a file to 3%, then it gave me the error. Further than i've gotten, but still not far enough.

SD Card M39 report 1:
M39
SD card in slot 0: capacity 1.99Gb, free space 1.94Gb, speed 20.00MBytes/sec, cluster size 4kb

SD Card M39 Report 2:
SD card in slot 0: capacity 3.98Gb, free space 3.89Gb, speed 20.00MBytes/sec, cluster size 64kb

Hey all, I've got a Duet Wifi that is seemingly not able to upload prints over wifi, likes to give errors when uploading .g files over wifi, and most frustratingly, gets stuck on "Processing" after I've selected a print on the MicroSD card. I have never had it upload a file over wifi after a week of tinkering, pre-fw update and post update, over two MicroSD Cards. I am using no adapters on the microsd cards, and the board does have a fan on it to keep things cool.

It's running the 2.03Beta3 firmware, Wifi Server ver. 1.23, and Web Interface Version 1.22.6. I have tested this issue with Chrome and Firefox with no improvement, and I have tried a known good MicroSD card and the original one it came with.

If I could get some pointers on what to test to narrow down my issues, it would be greatly appreciated.
