Unsolved wifi断开连接后有时候无法自动恢复
-
笔记本放家里,开了内网穿透。家里网络wifi路由器白天会重新一次。今天在公司远程,之后永久断开未能恢复。到家后,ubuntu系统显示wifi图标带一个问号。
停用wifi再重新启用,网络恢复。

不是每次都这样,目前发现了第二次,第一次是在家里,这次远程时,导致一个白天不能连上。

可以尝试禁止IPV6,默认使用IPV4.
具体方法在cmdline增加“ipv6.disable=1”:sudo vim /boot/firmware/extlinux/extlinux.conf default Linux coolpi label Linux coolpi kernel /Image initrd /initrd.img fdt /rk3588-cpcm5-notebook-v20.dtb append root=LABEL=writable rw rootfstype=ext4 console=ttyS0,115200n81 quiet splash plymouth.ignore-serial-consoles vt.global_cursor_default=1 irqchip.gicv3_pseudo_nmi=0 net.ifnames=0 ipv6.disable=1
