ubuntu上網(wǎng)配置(ADSL,路由,無線New)

1、裝完ubuntu估計(jì)首要的就是能上網(wǎng)了，因?yàn)楹芏嘬浖陌惭b通過：sudo apt-get install來完成，而這個(gè)是需要在網(wǎng)上下載軟件包的。不管怎么說，ubuntu的各種配置總是很麻煩，但這種麻煩也是由于我們不熟悉，就像windows一樣，其實(shí)配置起來也不簡單，熟能生巧嘛，嗯，我們進(jìn)入正題，這篇文章是我在ubuntu下剛剛用路由器上網(wǎng)之后就寫下的首先說一下adsl上網(wǎng)方式，很簡單，就一個(gè)命令：sudo pppoeconf也就是pppoe（以太網(wǎng)的點(diǎn)對點(diǎn)協(xié)議）的配置，前面是sudo，大家都很熟悉了，就是提升當(dāng)前用戶權(quán)限，如果你是普通用戶就用這個(gè)來完成根用戶級(jí)的操作。打完這個(gè)命令，之后就會(huì)出現(xiàn)

2、圖形化的界面，直接輸入用戶名和密碼，就應(yīng)該可以了。有一點(diǎn)注意的就是在輸入用戶名時(shí)，那個(gè)框不明顯，開始寫了一個(gè)好像是name，你需要把它刪除了才輸入，而不是直接在后面輸入，我犯過這個(gè)錯(cuò)誤。然后是經(jīng)常用到的路由器上網(wǎng)，這里指的是有線路由。網(wǎng)上有人說不需要配置，只要連上網(wǎng)線就能上了，這句話呢，一半對一半不對，為什么這么說呢，因?yàn)槿绻阋婚_始裝完ubuntu就直接用路由上網(wǎng)，并且路由已經(jīng)撥號(hào)成功，那么是很簡單的就能直接上網(wǎng)了，那為什么網(wǎng)上仍然有人說路由器上不了網(wǎng)呢，原因是像我一樣，先開始用的是ADSL的方式，后來再用路由器，網(wǎng)絡(luò)環(huán)境變了，這時(shí)系統(tǒng)的網(wǎng)絡(luò)配置文件需要更改了。ubuntu本身有一個(gè)網(wǎng)絡(luò)配置

3、的應(yīng)用程序network-manager，我是覺得不好用，于是卸載了：sudo apt-get remove network-manager -purge當(dāng)然你不想卸也沒關(guān)系，下面就如何配置，ubuntu的網(wǎng)絡(luò)環(huán)境配置是在文件：/etc/network/interface中，用：sudo gedit /etc/network/interface打開就可以看到很多配置信息，開始有：auto loauto eth0，。如果你是路由器上網(wǎng)，那就只需要把這個(gè)文件中的信息改成如下內(nèi)容即可：auto loauto eth0iface lo inet loopbackiface eth0 inet dhcp

4、其他內(nèi)容全部刪除，這里就是相當(dāng)于windows下的一個(gè)本地連接建立，注意的一點(diǎn)是這里以太網(wǎng)地址是dhcp方式獲得的，也就是路由器給你動(dòng)態(tài)分配的，如果你是靜態(tài)地址，也就是說你在這個(gè)局域網(wǎng)內(nèi)總是某個(gè)IP,如192.168.0.1，那么你可以如下配置：iface eth0 inet staticaddress 192.168.0.1netmask 255.255.255.0gateway 192.168.1.1（以上三行請根據(jù)實(shí)際更改）你可以在windows下在命令提示符中輸入ipconfig /all來獲得以上信息，這個(gè)命令會(huì)給出網(wǎng)絡(luò)的情況，如是否支持dhcp，好像有個(gè)項(xiàng)是DHCP ENABLED

5、,如果是yes，說明支持，那么你就用第一種配置，如果是no,那就用第二種，下面有如你的ip（沒有dhcp就是靜態(tài)ip），子網(wǎng)掩碼，網(wǎng)關(guān)等，請根據(jù)你的網(wǎng)絡(luò)實(shí)際情況配置。關(guān)于無線，一直沒有自己解決，網(wǎng)上的辦法無外乎以下兩種，一種通過ndiswrapper掛載windows的無線驅(qū)動(dòng)，另一種是直接去下載linux無線驅(qū)動(dòng)安裝，兩種方法我都試過，不知道是我哪里疏忽了還是怎么的，無線一直無法啟用。偶然之間，在ubuntu的論壇上看到某君如是說：在系統(tǒng)系統(tǒng)管理硬件驅(qū)動(dòng)里直接可以下載并激活無線驅(qū)動(dòng)，哈。難道網(wǎng)上這么多高人都傻了？這么簡單的問題被整得這么復(fù)雜。我試了一下，重啟之后，輸入iwconfig可以看到
