Re: 无法联接无线网
红色部分设置错误,应该是Managed,也就是说你根本没有真正连接成功,在设置无线网卡时应该选¨架构¨而不是Ad-Hoc:只要你是连接无线路由器之类的设备。。。wlan0 IEEE 802.11bgn ESSID:"jjy"

连接成功以后iwconfig的输出应该是这个样子的--看到和你的不同之处了吗:

Re: 无法联接无线网
我是在用你发过来的机器上的配置信息说话,原因、解决方法也给你了,先试试行不?--至少不会对你的机器有任何损害。。。aq9807xin 写了:可是右上角的图标显示是联接上了
给你看一下我把自己无线配置中的¨架构¨改成¨Ad-Hoc¨以后的iwconfig的输出,和你现在的情况几乎完全是一样的,这能说明问题了吧:

Re: 无法联接无线网
1. 鼠标左键点一下右上角那个网络连接的图标,出来一个下拉菜单,选最后一项¨编辑连接¨。aq9807xin 写了:实在对不起,我不明白您的意思,我不知道是怎么修改架构的。。。
2. 然后会出现一个窗口,在¨WiiFi¨下有你现在的无线连接,先鼠标选中这个连接,再按边上的¨编辑¨按钮。如果wifi下还没有东西,就选¨添加¨-->¨Wifi¨-->¨新建¨;
3. 在下面这个画面中点开Ad-Hoc边上的下拉箭头,选中¨架构¨; 4. 再选择¨保存¨
5. 去连你的wifi吧。。。
-看到你写的什么VPN了,设置wifi和VPN半毛钱关系都没有,严格按照我给你的步骤一步步做,一定可以成功的。。。

Re: 无法联接无线网
没问题,新手哪怕碰到小问题也是大麻烦。这样,你按照我的方式每做一步截个图(系统有一个缺省的截图工具)。看看你和我的步骤有什么不同:aq9807xin 写了:对不起,还是不行,我是按你说的做的,可是改完后,用iwconfig得到的信息还是一样的
第一步:点击桌面右上角的网络连接图标,出现下拉菜单: 第二步:选择上图中的¨新建连接¨
第三步:选择这个窗口中的¨添加¨ 第四步:选择¨WiFi¨ 第五步:选择¨新建¨ 第六步:输入你的网络名字和SSID,按照你的无线路由器上的配置来设,可以设成一样的 第七步:点开¨Wifi安全性¨,然后按照你的无线路由器上的设置输入相应的加密方式以及密码。然后¨保存¨ 第八步:设置好wifi后直接在配置窗口还看不到,要把第三步中看到的窗口先关掉,再按前面第一、二步重新打开,就能看到新添加的wifi连接了: 最后,再次点卡右上角网络图标,在搜索到的无线网络中选择你自己配置好的那个,就可以连接上了。--如果你的无线网络是隐藏的,要选择¨连接到隐藏的wifi网络,会提示你选择的。。。

Re: 无法联接无线网
先点左边栏最上面那个像个转动的风扇一样的ubuntu的图标: 然后在出现的这个画面中,在那行可以输入文字的地方输入screen,下面就会出现一个¨截图¨的程序,点击它,就可以截图了。 你可以先按照我前面给你的那个完整的步骤操作一遍,如果有任何一步对不上了,就截个图说明一下。。。aq9807xin 写了:大虾,我搞的半天,不知道怎么截屏。。。
