Bug Description
Ubuntu 7.10 with linux-ubuntu-
included driver r8169 gets loaded for device with Realtek RTL8101E chipset which is a Fast Ethernet device.
Problem: Ethernet networking has poor performance (with 100Mbps Full Duplex link transfer rates are only ~15Mbps)
Expected: transfer rates ~100Mbps
Workaround: removing the cited r8169 driver and installing by hand r8101 driver from www.realtek.com.tw then loading it via modprobe enables me to achieve transfer rates of ~ 80Mbps
Possible solutions: include driver r8101 into the modules package, remove r8169 driver, fix r8169 driver
Reference: the same misbehavior ascribed to r8169 driver but concerning Gigabit Devices with chipset RTL8111 has been discussed and fixed in Bug #114171 in launchpad.
Thank you!

I was having a similar problem with my Linksys EG1032v3. Using the r8169 driver, samba cifs transfers were about 14Mbps. After switching to the driver from the Linksys website (eg1032v3), transfers were back to normal at about 325Mbps. I tried testing it with the hardy alpha3 livecd, but I couldn't get it to boot.
