无线上网慢

无线上网非常慢，网址即便ping通也需要很长时间，iceweasel几乎没反应。请问怎么解决这个问题？

yangdawei.hit 写了： 03:00.0 Network controller: Broadcom Corporation BCM4313 802.11bgn Wireless Network Adapter (rev 01)
没额外安装驱动的话，估计现有驱动为 brcm80211(brcmsmac)，支持不佳：
参考 https://wireless.wiki.kernel.org/en/use ... /brcm80211
wireless.wiki.kernel.org 写了：Please note: at least BCM4313 is not fully supported. Some models appears to work (users reported success), but some don't, and there's no indication that this is going to change. For example: http://marc.info/?t=138817851800006&r=1&w=2
而另一个开源驱动 b43 根本不支持此卡

安装 broadcom-sta-dkms 这个包，换用私有驱动 'wl' 试试。

现在是 wl 驱动了么，lshw -C network 看一下

不像是DNS问题了，ping 114 60多毫秒，ping 你的网关试试。ping 192.168.0.1

sudo route -nv
代碼:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
0.0.0.0 192.168.0.1 0.0.0.0 UG 600 0 0 wlan0
169.254.0.0 0.0.0.0 255.255.0.0 U 1000 0 0 wlan0
192.168.0.0 0.0.0.0 255.255.255.0 U 600 0 0 wlan0
1. 有兩個 route
2. 把這個
169.254.0.0 0.0.0.0 255.255.0.0 U 1000 0 0 wlan0
移除 見 3.
2-1. 但是 重開機 可能還在 可能原因 你的 網卡設定有問題

3. 移除 169.254.0.0 route 方法
3-1. 從 終端機
sudo route del -net 169.254.0.0 netmask 255.255.0.0 wlan0
3-1-1. 再一次 檢查
route -n
看看 169.254.0.0 路由 是否不見了
3-1-2. 看看 无线上网 有沒有快一點

3-2. 如果 你希望一開機就自動執行 把 169.254.0.0 路由 刪除
gksudo gedit /etc/rc.local
把
sudo route del -net 169.254.0.0 netmask 255.255.0.0 wlan0
放在
exit 0
前面即可
3-2-1. 如果是 systemd 上述方法 也許需要修正 請再貼文
