네트워크 어댑터 - CTRL 이벤트 검색 실패(하드웨어 불안정)

저는 오래된 HP 노트북(HP Pavilion G6 2298SE)에서 Manjaro Linux를 사용하고 있습니다. 이 노트북에는 다음(Ralink) 네트워크 어댑터가 있습니다.

07:00.0 Network controller: Ralink corp. RT5390R 802.11bgn PCIe Wireless Network Adapter

문제는 제가 끊임없이 연결이 끊어진다는 것입니다(하루에 4~5번). 이 경우 NetworkManager는 목록에 무선 연결을 표시하지 않습니다. 연결을 끊은 후 "lspci", "ip" 및 "lshw"는 결과에 네트워크 어댑터를 표시합니다.

연결 해제 후 "lspci" 결과:

[user:pc:~]lspci | grep -i wireless
    07:00.0 Network controller: Ralink corp. RT5390R 802.11bgn PCIe Wireless Network Adapter

연결 해제 후 "ip" 결과:

[user:pc:~]ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: wlo1: <BROADCAST,MULTICAST> mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000
    link/ether 11:22:33:44:55:66 brd 11:22:33:44:55:66
3: eno1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc fq_codel state DOWN mode DEFAULT group default qlen 1000

연결 해제 후 결과는 "lshw"입니다. "비활성화됨"이라고 표시됩니다.

[user:pc:~]lshw -class network

그러나 "ifconfig"는 결과에 네트워크 어댑터를 표시하지 않습니다.

연결을 끊을 때 "journalctl -xe"는 다음 메시지를 표시합니다.

"ip" 명령은 네트워크 어댑터가 "꺼져 있음"을 표시하므로 시작하려고 하면 다음 오류가 발생합니다.

[user:pc:~]sudo ip link set down wlo1 && sudo ip link set up wlo1
    RTNETLINK answers: Device or resource busy

몇 달 전에는 이런 일이 거의 발생하지 않았지만(1주일에 한 번 또는 2주에 한 번) 이제는 문제가 더 자주 발생합니다(하루 4~5회). 이 문제를 해결하려면 랩톱을 다시 시작해야 했고 네트워크 어댑터가 (잠시 동안) 다시 제대로 작동하기 시작했습니다. 따라서 질문은 다음과 같습니다. 내 네트워크 어댑터가 죽어가고 있습니까? 아니면 다른 문제(드라이버, 전원 관리 등)가 있습니까? 이것 좀 도와주실 수 있나요?
