[SOLVED] Very poor network connection on new PC

arubin · 09-05-2012, 04:54 PM

My new PC is very slow connecting to the internet. It is plugged in directly through ethernet. Connections on windows on the same PC are very fast. Do I need an updated driver?

I use the same card, but mine is (rev 06) rather than (rev 09). I have no problem with the drivers that I can tell.
I do connect using a static IP. Could this be a DHCP problem?
Just wanted to add I'm running 32 bit slackware-current (I see you're running 64bit)

arubin · 09-05-2012, 06:40 PM

Same problem running DHCP or static. When I boot into Windows it's very fast.

WetDreams · 09-05-2012, 08:12 PM

Hey, I am not sure if this will be of any help, but I had the same problem with internet connections being too slow every time I tried installing slackware on my computers. Try to blacklist ipv6 by adding

Code:

blacklist ipv6

in /etc/modprobe.d/blacklist and reboot.

With ipv6 disabled internet speed is back to normal for me. I am a newbie and I don't understand why this is happening, but it may have to do something with the router model or configuration since it happens on both of my home computers. Also I don't remember having these issues with my old router, it could be a coincidence, I don't know.

damgar · 09-05-2012, 09:31 PM

I have issues sometimes if I don't set a static DNS server. I got around this by setting my DNS server to the local address of my router and it's such a habit that I can't tell you what the problem actually was or if it still exists for me. Before I set the router's address I just used 4.2.2.1 and 8.8.8.8 as the DNS servers which I now have set statically set in my router. YMMV

Setting your own ISP's DNS servers might work better for you, my isp has pretty slow DNS.

arubin · 09-06-2012, 03:09 AM

Damgar I don't think this is a DNS issue. My old PC was fine with the same setup I am using.

I will not be able to work on this for a few days. There might be an updated Realtek driver I can install and I shall look into WetDreams suggestion.

Or perhaps Slackware 14 will have been released and that will work better.

You should do this first as it's the most likely culprit.

Just a guess, but...

You are using the r8169 driver but have a r8168b ethernet card. It may be the case that blacklisting r8169 and installing the r8168 driver from realtek will help. Another solution that might help is manually setting the speed of your ethernet card to 100 instead of 1000 via ethtool. This is a known and very old bug. I also suggest to search this forums or the whole web for r8168 and r8169 driver issues.

edit: An indicator that this is the actual problem would be many "eth0: disconnect/connect", "eth0: autonegotiated.." or similar messages in your log files.
edit2: Yet another indicator would be many lost packages when pinging any other box (e.g. your router)

arubin · 09-06-2012, 08:53 AM

These pages indicate that the r8169 driver might be what is at fault.

The thread http://www.linuxquestions.org/questi...ed-fyi-928824/ contains a solution. Although I would prefer the latest driver which can be found here: http://www.realtek.com.tw/downloads/...&GetDown=false. If I have some spare time, I may even be able to find the SlackBuild I once wrote for this purpose.

Fred-1.2.13 · 09-06-2012, 10:16 AM

Just for a quick test... login as root and launch startx as root. See if things run faster as root.....

Had a machine do this to me once... never did figure out why as it was a junker test box so I didn't pursue it. Was very weird, network (Internet) crawled as a regular user but ran fine as root.

arubin · 09-06-2012, 12:18 PM

Ok. Found a few minute to play with the PC. Followed tc_'s advice in #10 and had a 12 Mbps download. Around what I might expect from my broadband.

Thanks

Glad you got things sorted. Curious as to why my card seems to work fine.
Perhaps I'll be back to this thread when my network starts to suck wind.

Thanks for posting the resolution.
