uTrack-X32 recording suddenly stops!

I only had problems with the TP-Link TL-WR841N, while the second router I tested (TP-Link TL-WR802N) ran smoothly without problems. I tried different cables but it doesn’t depend on that. I’ll try soon connecting to a computer or to different routers to see if it happens again.
Thank you for the assistance, let’s hope to figure it out together 🙂
