Ubuntu 17.04로 업그레이드한 이후 Wi-Fi 연결이 불안정한 것으로 나타났습니다(2,4Ghz 및 5Ghz 네트워크에서 연결이 무작위로 끊어짐). 업그레이드를 해보았어요iwlwifi 드라이버, 그러나 불행하게도 이것은 도움이 되지 않았습니다.
내 네트워크 카드는 Intel 7265입니다.
Network controller [0280]: Intel Corporation Wireless 7265 [8086:095b] (rev 99)
Subsystem: Intel Corporation Dual Band Wireless-AC 7265 [8086:5210]
Kernel driver in use: iwlwifi
어떤 이유로 Ubuntu가 로드되는 것 같습니다.iwflwifi-7265D-26
modinfo iwlwifi | grep 7265

어떤 펌웨어를 로드해야 합니까? 펌웨어 7265와 펌웨어 의 차이점은 무엇입니까 7265D(2,4/5Ghz인 것 같나요?). Ubuntu가 최신 펌웨어(7265D-29)를 사용하지 않는 이유는 무엇입니까?
감사해요!
추신: BSSID를 2,4Ghz&5Ghz 네트워크로 설정하려고 했지만 문제가 해결되지 않았습니다.
