Kaiwai Gardiner, The following is my test and it's result:
Parameters: test case: surfing the internet time: 4 hours OS: B81 and B86 driver: iwk1.1 security: open configure mode: nwamd and manual Result: B81 + nwamd: work normally and work normally after OS reboot B81 + manual: work normally and work normally after OS reboot B86 + nwamd: "link down and up" occur and work normally after OS reboot B86 + manual: work normally and work normally after OS reboot Taking account of above results, I think iwk driver is good and the problem is from nwamd. So, could the developer of nwamd please give more explanations about this problem?
