connect : wifi / cable ?

首先聲明, 我係唔識嘅:-

由乜 version 昇去乜版
wifi 得唔得
貼 ifconfig 上嚟睇吓
試吓 sudo ifconfig eth0 up, 再 ifconfig
睇吓有冇嘢唔同咗

    ubuntu 14 auto update files...don't know what it had updated...

作者: eieio    時間: 2016-5-13 22:13

maybe it's time to reinstall the OS since I have been using ubuntu 14 for 1 year.
any light weight linux comparable to the functions and ease of use to ubuntu?
or just install ubuntu 16?

update冇左network好大幾會係 network card個 udev id轉左， 一係 udev id再detect過， 一係去/dev找返轉左做eth?  再set過ip , gateway之類

ubuntu 已經係好 user friendly,
好在有第二部機上到網,
1. 冇重要 data、冇心機、冇時間, 重裝。
2. 上網摷, 從錯誤中學習 ...
e.g. google keywords
ubuntu 14 upgrade no network

in archlinux, i will "ip addr" to see if my card is present and has a ip address, you can do the same thing with "ifconfig" maybe.
if the card is not present, that is a driver problem.
if the card is present but no ip address, try "dhcpcd enp3s0", that is what i do in arch, some network manager does not do their job.
if the card is present and has a ip address but no internet, still network manager problem.

    重裝吧

我都中咗，好奇怪，ubuntu顯示一切正常，ifconfig 有Rx Tx增加, arp 收到其他機MAC, 但Tx 實際冇發出去。
google 一輪都無解。
暫時發現有workaround: 重載網卡驅動。例如intel 網卡：

sudo modprobe e1000e -r
sudo modprobe e1000e

好彩我主要用WIFI.

我都試左幾次
不過結果都係service network-manager restart
一招KO

之後出的update，已解決了這問題。
最終都冇從裝，咩都冇做過。

上唔到網, 點 update

---

作者: control1    時間: 2016-5-29 09:06

用 sudo dhclient eth0 可暫時上到網，但下次boot機又上唔到。

作者: KinChungE    時間: 2016-5-29 16:22

我clean install ubuntu 16.04都上唔到網
之後發覺/etc/resolv.conf入面冇dhcp既dns server
手動加翻就得

我部SP4有時開完機後WIFI會灰左
要restart network-manager先得
