I have a question regarding wireless driver behaviour.
The use case is next:
PC (Windows 7 x64, driver: Intel Dual Band Wireless-N 7260) connected to the Wi-Fi router (SSID: s1, channel: 11).
On the other network (SSID: s2, channel: 9) two devices are transmitting data via iperf.
After several minutes link on the PC performs re connections to the network.
How is that possible? Is the problem in driver?
I expected just increasing packet loss ratio and delays without looping linkdown-linkup.
Logs from Wi-Fi PROset attached:
