linux-howto

http://ubuntuforums.org – Hello, I have a Dell XPS M1210. Ethernet adapter seems to be Broadcom Corporation BCM4401-B0 100Base-TX (rev 02). When connect an ethernet wire with internet access, there seems to be no response whatsoever (lights on adapter itself not working and no connection established), whereas with same computer on Windows operating system (I used to have windows and switched to Ubuntu) adapter and connection worked fine. Here is output of: ~:$ lspci | grep -i eth Broadcom Corporation BCM4401-B0 100Base-TX (rev 02) ~:$ ifconfig eth0 eth0 Link encap:Ethernet HWaddr 00:18:8b:a4:7d: (Hardware)

Stories similar to [ubuntu] Ethernet Adapter Not Responing

I'm new-ish to Ubuntu.

My motherboard ethernet input has broken so I am now trying to use an USB adapter.

The TRUlink ethernet adapter (USB 2.0 10/100/1000 Ethernet Adapter) that I am trying to use does not seem to be working in Ubuntu 11.04.

The output from "lspci | grep Ethernet" is:

Code: 02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.

Lan adapter Broadcom 57xx 3 years 11 weeks ago

Hi there,

I have not used Linux since university and I finally got fed up with windows, so I installed Opensuse 11.2 on my Dell D430. Changed the wireless adapter to an intel one and everything work, except the Broadcom ethernet 5257 Adapter.

I tried everything with my limited knowledge, using the bnx2 module instad, blacklisting tg3 etc but to no avail... no eth0

I have a small home router running OpenWrt (Kind of embedded Linux for routers). It has five Ethernet ports, one labeled WAN and four labeld LAN 1 to 4.

I did a first time install of Ubuntu 11.10 using Wubi and the ethernet connection on my laptop. (so I know that the ethernet interface is working and connected correctly). I finished the install and booted up Ubuntu. The wireless connection works find, but I am not able to get the wired connection to work.

New to Linux/Ubuntu, I have searched and tried a number of suggested solutions posted here and on other Ubuntu forums. My son received a computer with Xubuntu 9.04 already installed. We first tried a wireless adapter for internet connection, but got no results so I have run a cable directly to the Verizon Router 9100EM, but it connected to google.com and then disconnected.

Ethernet connection problem 13 weeks 4 days ago

Hi,

I have problems with ethernet (eth0 Wired connection) since I installed Raring (for about 4 days). I'm considering raising a bug report related to the kernel, but I thought it might be good idea to consult it there :)

So, the problem is: System boot -> everything ok. After some random time, in scale of minutes to hours, connection becomes totally unresponsive at one moment.

Hi,

obviously, I have just started using Linux. I have installed Ubuntu 10.04 on my Acer 5735z (specs an be found here).

PROBLEM: I manage to get a wireless connection with my pc, but when trying to use an Ethernet cable to connect the result is a slow Internet connection which jump online/offline.

In short: I'd like to be able to telnet to my modem from my PC via my router.

There is a simple home router on 192.168.33.1. It is running OpenWrt.
