14.04 wifi断开原因 2

Ubuntu 14.04 HW：rt2860（我确定是我的 eeepc 1000he）但从 ubuntu 看到是 rt2890

lspci：

01:00.0 Network controller: Ralink corp. RT2790 Wireless 802.11n 1T/2R PCIe

模块：rt28000pci

这是一个 wep 连接，它只连接了几分钟，然后因为原因 2 而断开连接，这里只是来自 dmesg 的几行。

在开放网络上，它运行起来没有问题，我会尽快检查 WPA。有什么想法吗？

请一次运行以下命令，并复制和粘贴以确保准确性：

echo "options rt2800pci nohwcrypt=1" | sudo tee /etc/modprobe.d/rt2800pci.conf
sudo modprobe -rfv rt2800pci
sudo modprobe -v rt2800pci

此命令将加密从硬件更改为软件，并且在许多情况下可以解决您遇到的问题。

Wep 不是很安全，并且 ubuntu 将比任何其他设置更好地连接到 wpa2 (AES) (CCMP)，而不是混合模式或特别是 (TKIP)。
