Thread: Nework problems between Ubuntu 10.04 64 bits and Huawey HG520
this first post, , not fluent in english, sorry in advance possible mistake.
fist describe context, problem, , include detailed system information. have been looking problem in net, without results.
context:
have changed pc 32 bit architecture 64 bits. have installed windows 7 , ubuntu 10.04. in previous pc had installed ubuntu 10.04 , windows xp (without these problems). pc connected, via cable, huawey hg520 gateway.
problem:
internet connection unestable: times lost , recovered. problem lies between ethernet card , router, cannot reach router in such cases (ping 192.168.1.1 gives "host unreachable", , tcpdump gives arp request "who has 192.168.1.1"). have not issue hen windows 7, , had not problem ubuntu 10.04 when architecture 32 bits. have tried set network configuration manually, same result: inestable conection internet.
have tried ubuntu 11.10, simmilar (even worse) results.

finally found answer myself in http://ubuntuforums.org/archive/inde...t-1436667.html.
answer hidden in long debate, copy here solution:
problem due incorrect driver loading 2.6.32-22-generic-pae kernel (may apply other kernels also).
how rectified issue.
1. check model number of ethernet controller:
$ lspci | grep realtek
02:00.0 ethernet controller: realtek semiconductor co., ltd. rtl8111/8168b pci express gigabit ethernet controller (rev 03)
2. check driver kernel loading:
$ lsmod | grep r816*
r8169 91629 0
can see have r8169 driver r8168 chipset cause of our issues.
3. download 8168 linux drivers realtek website: http://www.realtek.com.tw/downloads/, choosing proper card (in case, pci express).
4. cd download directory , extract:
$ tar -xvf r8168-8.027.00.tar.bz2 (or ever driver downloaded
5. run script superuser autocompile driver:
$ cd r8168-8.027.00
$ sudo ./autorun.sh
6. [optional] test driver
$ sudo rmmod r8169
$ sudo modprobe r8168
$ sudo /etc/init.d/networking restart
network should , running new driver. make change permanent.
7. blacklist r8169.
$ sudo gedit /etc/modprobe.d/blacklist.conf
append following lines:
# blacklist realtek rtl8111/8169 gigabit driver
blacklist r8169
save , quit.
8. update driver cache.
$ update-initramfs -u
reboot , see if correct driver has loaded:
$ lsmod | grep r816*
r8168 91629 0
, should hunky-dory.
