Intel Dual Band Wireless-N 7260 linkdown-linkup in case of interferation

Hello,

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:

Driver Intel Dual Band Wireless-N 7260 17.15.0.5 - log1.txt

Driver Intel Dual Band Wireless-N 7260 18.21.0.2 - log2.txt

Thanks in advance,

Viacheslav.
