Hi all,
I hoping someone can help me with an issue I've been struggling with regarding the Realtek r8169 driver. It seems that the onboard lan nic is somehow limited on the transmit on eth0 interface to anywhere from 30-90 KB/s. The receive is usually around 10-30 MB/s.
Here's some background that may be useful. I recently upgraded my 10/100 Buffalo 4 port router to a Linksys e3000 10/100/1000 router running tomatousb. I have a mix of windows and ubuntu machines on the network, most of which are wireless. This machine is the my office hooked up to the router by 1 meter cat5 cabling. I have tried many different cables, they all exhibit the same symptom. In the posting below, I have temporarily added a usb wireless g nic to get some decent transmit speed. I have tried the r6169 build (version 6.014) from realtek. The 6.013 wouldn't compile. I have also tried the 64 bit builds of windows 7 and vista inside of ndiswrapper. They failed misably, but the XP 64 bit driver installed and actually gave me an IP address, though it wouldn't actually send any data, pings didn't work, etc.
I've used netio to test network throughput between computers and bmon to realtime track it on the machine.
Sorry for the long post. Thanks for your time and help!

Some say to remove ip6 to increase speed. I used the following to no avail:Code:# ethtool eth0 Settings for eth0: Supported ports: [ TP MII ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Half 1000baseT/Full Supports auto-negotiation: Yes Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Half 1000baseT/Full Advertised pause frame use: No Advertised auto-negotiation: Yes Link partner advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Half 1000baseT/Full Link partner advertised pause frame use: No Link partner advertised auto-negotiation: Yes Speed: 1000Mb/s Duplex: Full Port: MII PHYAD: 0 Transceiver: internal Auto-negotiation: on Supports Wake-on: pumbg Wake-on: d Current message level: 0x00000033 (51) drv probe ifdown ifup Link detected: yes
This is where I'm throughly confused. I've read many posts about the router/nic not properly communicating their capabilities and this is the typical reason for the slowness. Firstly, I'd imagine the slowness would be in both directions, in this case it is only in the transmit side from the nic. Anyways, I try to drop the speed to 100 and duplex to half, since that's all mii-diag says it the nic can do (lshw and ethtool (and Realtek) say it's gigabit capable).Code:# ifconfig eth0 del fe80::250:8dff:fe9a:3c1c/64
So why does "speed 1000 duplex full autoneg on" work, but it really isn't showing that speed?Code:# ethtool -s eth0 speed 100 duplex half autoneg off # mii-diag -v mii-diag.c:v2.11 3/21/2005 Donald Becker (becker@scyld.com) http://www.scyld.com/diag/index.html Using the default interface 'eth0'.

Should I just install another nic?!
Thanks again!
