在我的 64 位 Ubuntu 18.04 上,WiFi 无法工作 - 我的 WiFi 网络不可见且无法选择。我得到了以下结果:
$ lspci -vq | grep -i wireless -B 1 -A 5
01:00.0 Network controller: Ralink corp. RT3090 Wireless 802.11n 1T/1R PCIe
Subsystem: Lite-On Communications Inc RT3090 Wireless 802.11n 1T/1R PCIe
Flags: bus master, fast devsel, latency 0, IRQ 17
Memory at fea00000 (32-bit,ran the following command non-prefetchable) [size=64K]
Capabilities: <access denied>
Kernel driver in use: rt2800pci
Kernel modules: rt2800pci
这是缺少驱动程序的情况吗?我的以太网连接工作正常。
编辑:
$ rfkill list all
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
它仍然看不到 WiFi 网络。

正在重启。这是台式机系统,不是笔记本电脑。它距离路由器约五英尺。
断开互联网,重新启动,运行命令,然后重新连接互联网。dmesg | grep -e rt2 -e wlp > info.txt
