Santosh, >From your ifconfig, lo is the software loopback device and pan0 is your >bluetooth device You do not have the Ethernet driver installed for your Ethernet controller: Atheros Communications AR8152 v1.1 Fast Ethernet (rev c1) This thread shows how to do it, http://ubuntuforums.org/showthread.php?p=9449490 Give that a try and let us know how it goes
You can also install the driver for your Broadcom Wireless from the menu System -> Administration -> Hardware drivers Satish > -------Original Message------- > From: santosh kumar <[email protected]> > To: twincling <[email protected]> > Subject: [twincling] Problem in network configuration > Sent: 18 Aug '10 23:28 > > Hi All, > I recently bought Dell Inspiron N4010 laptop and installed Ubuntu 10.04-32 > bit. > I'm unable to detect my wired ethernet. > why my ethhernet interfaces are not shown?? > > Please help out > > These are some commands. > > ifconfig -a > lo Link encap:Local Loopback > inet addr:127.0.0.1 Mask:255.0.0.0 > inet6 addr: ::1/128 Scope:Host > UP LOOPBACK RUNNING MTU:16436 Metric:1 > RX packets:76 errors:0 dropped:0 overruns:0 frame:0 > TX packets:76 errors:0 dropped:0 overruns:0 carrier:0 > collisions:0 txqueuelen:0 > RX bytes:5840 (5.8 KB) TX bytes:5840 (5.8 KB) > > pan0 Link encap:Ethernet HWaddr d6:44:c0:87:0c:80 > BROADCAST MULTICAST MTU:1500 Metric:1 > RX packets:0 errors:0 dropped:0 overruns:0 frame:0 > TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 > collisions:0 txqueuelen:0 > RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) > > ################################################ > > 00:00.0 Host bridge: Intel Corporation Core Processor DRAM Controller (rev > 12) > 00:02.0 VGA compatible controller: Intel Corporation Core Processor > Integrated Graphics Controller (rev 12) > 00:16.0 Communication controller: Intel Corporation 5 Series/3400 Series > Chipset HECI Controller (rev 06) > 00:1a.0 USB Controller: Intel Corporation 5 Series/3400 Series Chipset USB2 > Enhanced Host Controller (rev 06) > 00:1b.0 Audio device: Intel Corporation 5 Series/3400 Series Chipset High > Definition Audio (rev 06) > 00:1c.0 PCI bridge: Intel Corporation 5 Series/3400 Series Chipset PCI > Express Root Port 1 (rev 06) > 00:1c.1 PCI bridge: Intel Corporation 5 Series/3400 Series Chipset PCI > Express Root Port 2 (rev 06) > 00:1c.5 PCI bridge: Intel Corporation 5 Series/3400 Series Chipset PCI > Express Root Port 6 (rev 06) > 00:1d.0 USB Controller: Intel Corporation 5 Series/3400 Series Chipset USB2 > Enhanced Host Controller (rev 06) > 00:1e.0 PCI bridge: Intel Corporation 82801 Mobile PCI Bridge (rev a6) > 00:1f.0 ISA bridge: Intel Corporation Mobile 5 Series Chipset LPC > Interface Controller (rev 06) > 00:1f.2 SATA controller: Intel Corporation 5 Series/3400 Series Chipset 6 > port SATA AHCI Controller (rev 06) > 00:1f.3 SMBus: Intel Corporation 5 Series/3400 Series Chipset SMBus > Controller (rev 06) > 00:1f.6 Signal processing controller: Intel Corporation 5 Series/3400 > Series Chipset Thermal Subsystem (rev 06) > 03:00.0 Network controller: Broadcom Corporation Device 4727 (rev 01) > 04:00.0 Ethernet controller: Atheros Communications AR8152 v1.1 Fast > Ethernet (rev c1) > ff:00.0 Host bridge: Intel Corporation Core Processor QuickPath > Architecture Generic Non-core Registers (rev 02) > ff:00.1 Host bridge: Intel Corporation Core Processor QuickPath > Architecture System Address Decoder (rev 02) > ff:02.0 Host bridge: Intel Corporation Core Processor QPI Link 0 (rev 02) > ff:02.1 Host bridge: Intel Corporation Core Processor QPI Physical 0 (rev > 02) > ff:02.2 Host bridge: Intel Corporation Core Processor Reserved (rev 02) > ff:02.3 Host bridge: Intel Corporation Core Processor Reserved (rev 02) > > ####################################################################### #
