RT2561/RT61 无线无法获取 SSID

我刚刚将我父母的电脑从旧的（9.04）Ubuntu 升级到 11.10。而且...11.10 会自动安装无线适配器的驱动程序，这很好。但电脑无法获取路由器的 SSID。这是一个全新的 Netgear 600 路由器。家里的所有其他电脑都运行正常。将其作为隐藏网络连接到它工作正常。我之前在各种版本的 GNU/Linux 上进行过几次无线设置，在我看来一切都设置正确，但断开连接时似乎看不到路由器。

有什么建议么？

dmesg，如果有用的话……http://pastebin.com/ebpjssCs

答案1

好的，我在网络启动安装后遇到了同样的问题：网络管理器没有列出任何 wifi 接入点

我所做的：清理 /etc/network/interfaces，删除网络管理器小程序中的所有连接条目（有线、wifi......）

最后对网络管理器进行重新配置

sudo dpkg-reconfigure network-manager

答案2

建议：清理网络监控连接条目和 /etc/network/interfaces

删除网络监视器小程序无线窗格中的所有连接条目。

清理你的 /etc/network/interfaces : 仅环回

/etc/网络/接口

auto lo
iface lo inet loopback

然后重新启动网络监视服务
