系統詳細資料：Ubuntu 12.04 LTS，核心為 3.5.0-45-generic，筆記型電腦為 Dell Sputnik 3 XPS 13，無線網路卡為 Intel Wireless 7260(rev 6b)
我在連接校園 CS 無線網路時遇到問題，但在連接任何其他網路時卻遇到問題。我的系統管理員建議使用以下修復程序這裡。我在接受的答案中安裝了向後移植並重新啟動。當我重新啟動時，NetworkManager 未偵測到我的無線卡，且 wlan0 介面未啟動並執行。我立即卸載了向後移植，但問題仍然存在。我嘗試從以下位置為我的系統安裝驅動程式這裡但這也沒有解決問題。我認為恢復出廠設定可以解決問題，但我寧願避免這種情況。

如果有人能幫我解決這個問題那就太好了。筆記型電腦沒有以太網端口，因此我依賴無線工作。
編輯：chili555 幫助我透過聊天完成了這項工作。問題是戴爾強制筆記型電腦透過 DKMS 使用 3.10 版向後移植。我們從 DKMS 中刪除了它，然後安裝了 3.13。請注意，每次安裝新核心時，都需要為新核心重新編譯並重新安裝 3.13。
答案1
為了方便我們排除故障，請返回反向移植檔案並執行以下操作：
cd ~/Desktop/backports-3.11-rc3-1/
make clean
make-defconfig-iwlwifi
make > make.txt
在您的使用者目錄中找到檔案 make.txt 並將其貼到此處，並在您的回覆中向我們提供連結。我懷疑“make”有錯誤，我想看看它。http://paste.ubuntu.com
另外，安裝較新的韌體：
cd /lib/firmware
sudo mv iwlwifi-7260-7.ucode iwlwifi-7260-7.bak
在另一台電腦上取得此文件，然後使用 USB 記憶棒或類似裝置將該文件拖放到桌面上：https://git.kernel.org/cgit/linux/kernel/git/egrumbach/linux-firmware.git/plain/iwlwifi-7260-7.ucode
cd ~/Desktop
sudo cp iwlwifi-7260-7.ucode /lib/firmware
重啟。
你的「品牌」看起來很完美。我建議你安裝它：
cd ~/Desktop/backports-3.11-rc3-1/
sudo make install
sudo modprobe -r iwlmvm
sudo modprobe -r iwlwifi
sudo modprobe iwlwifi
是否創建了無線介面？
iwconfig
檢查資訊性訊息：
dmesg | grep iwl
正確的韌體是：
-rw-r--r-- 1 root root 683236 Jan 17 11:34 iwlwifi-7260-7.ucode
答案2
好的，你的筆記型電腦受 Ubuntu 支援：
如果您可以連接到校園以外的所有其他網絡，那麼我建議問題出在您的校園網絡上，而不是您的筆記型電腦。
我建議您恢復到舊固件，甚至可以進行全新安裝並從那裡進行故障排除。
然後，在開始更改驅動程式之前，您可以使用wireshark對網路條目進行故障排除（雙方都在系統管理員的幫助下）。
另外，您的連線有什麼問題，即您是否獲得了 169 位址或 0.0.0.0 位址，或者它只是拒絕您的網路存取。
注意：接入點供應商也可能造成網路進入問題。
祝你好運
