目前，我必须断开连接并再次连接才能为我的 Linux 计算机使用互联网。它适用于我的平板电脑。
你知道这可能是什么原因吗？
当我使用互联网超过一分钟左右时，它就不再起作用了。
我是不用电线连接的。

答案1
我以前也遇到过这种情况。似乎有些无线网卡在 *nix 上无法很好地与 802.11n 配合使用。答案（如果这确实是你的问题）如下所述这里例如，完全禁用 802.11n：
echo "options iwlagn 11n_disable=1" | sudo tee /etc/modprobe.d/iwlagn.conf
sudo modprobe -rf iwlagn
sudo modprobe -v iwlagn
要了解您拥有的无线网卡类型：
lspci | grep -i ethernet
