I have both frequency bands for wireless up and running (2.4 and 5 GHz), both on max. 144 MBit neighbor-friendly. A total of four units are connected via WLAN (laptop, XBOX, Surface, mobile phone), some with 2.4 Ghz, with some 5 GHz. I had to start at random crashes of the wireless connection, which could only be remedied by a router reset. The complete Sunday, everything went smoothly, just I had another crash. The latest firmware is on it which has been offered to me right when you initially set (3.0.12). ... I'm curious. The problem with the regular WiFi crash was unfortunately already repeatedly posted here. The latest firmware is but from April this year; because I had already dei hope that the problem is now resolved.
Will report.
Update 02:05:14: Since 3 days it runs without interruption. Have dzu disabled IP_V6, maybe it was because. Anyway, I'm thrilled by the quality Wi-Fi. Here I have almost full 100 Mbit and even at a distance and walls still half. That's what my predecessor router failed by far.
