Thread: 11.10 wired network problem

hi, im new forum.

been using ubuntu on various pc's laptops few years. im user rather developer , capable of general maintenance.

problem:
installed ubuntu 11.10 64bit on new asus et2410ints in dual boot win7 64 bit.

install problem option install alongside not provided -after partition work install ok.

problem seems 11.10 unable access full broadband speed , network connection not working or being throttled 11.10 instal. im using wired ethernet connection through netgear powerline adaptors , not using wifi @ all.

used speedtest.net check - win 7 boot gives 14-16mbits/s down , 1.5 - 11.10 boot gives 2.3mbit/s down , 0.02 up. have tried complete reinstall , same occurs.

connection fine laptop running xubuntu 11.10 via wifi.

running software updates hard due connection timing out.

suggestions or pointers getting network connection working appreciated

have seen people request findings of sudo lshw -c network here are:

hi, please show results of:

code:

lspci -nnk | grep -ia2 net

i suspect running these commands 1 @ time fix problem want make sure of ethernet adapter first.

code:

sudo apt-get install --reinstall linux-headers-generic build-essential dkms  wget http://r8168.googlecode.com/files/r8168-8.025.00.tar.bz2  tar xvf r8168-8.025.00.tar.bz2  cd r8168-8.025.00  sudo modprobe -rf r8169  sudo ./autorun.sh  echo 'blacklist r8169' | sudo tee -a /etc/modprobe.d/blacklist.conf  sudo modprobe -v r8168  sudo depmod -a  sudo update-initramfs -u
