Everything seems to be working fine. I've been uploading files for days now. Then it just stopped uploading files. It still connects via web, and responds to my commands. But now I have to manually place gcode files on the SD card, but then I can print via web interface. I've reset my router, my printer, and my PC. I ran an M122 and found no abnormalities. Any ideas?

Update: It just successfully uploaded one small file. It's a signal issue. Strange that I had no problems, and then bam!
