Since the last firmware upgrade a few weeks ago my MR1100 Nighthawk M1 keeps dropping out. It reconnects after 30 seconds but it is very annoying, especially when streaming audio or video. I'm using Firmware Version NTG9X50C_12.06.02.00 on my Lenova laptop using Windows 10. The router is tethered directly to the laptop, not using WiFi. Everything has been fine before the upgrade but it is not fine now! Any suggestions?
