leeAngry, please edit your post.
When pasting code, please use [ code ] tags https://bbs.archlinux.org/help.php#bbcode

like this

It makes the code more readable and more convenient to scroll through.

crap sorry about that

The traceroute looks reasonable. Except -- That first hop goes to 192.168.1.10 I usually expect a gateway to be at *.*.*.1. It does not have to be, but it often is.
Then, hops 2 and 3 are going to 172. and 10. addresses. Those are still private networks.

So, three private networks before you reach the internet at wegsch01.mywave.at (85.193.128.129).

Can you tell us more about the network? Example: Are you cascading a router with a DSL modem?
What is that first hop?
Are you, by chance, running inside a VM and the first hop is to the host?
How are you setting your IP address? (Static or Dynamic) Any chance multiple machines are using the same address?
Are you using the wireless, or the wired network?
Are they both talking to the same router at the same time?
What is the output of ip addr

I have been experiencing similar issues (not nearly as bad) with my card (Atheros ar5007eg) and I saw this post: https://bbs.archlinux.org/viewtopic.php?id=120684
I checked it out and it did not help me (not sure if it a specific issue to that card) but it may be worth a shot.

i'm on a wireless router... not sure of much info on the router because i'm in a hotel in austria. i've just been noticing more and more frequently lately and would like to get to the end of it.

Can you try using mtr instead of traceroute? You'll have to install mtr, and then use something like 'mtr -rc4 www.google.com', it will tell you where packets are getting lost (I don't know how to see with traceroute where packets are getting lost, if it is possible with traceroute).

No packet loss there, 4 packets were sent and 4 packets were received for each hop.

Is this your network or are you still at the hotel? It might help (or not) to have more details about the first 3 hops which look a bit suspicious, like ewaller pointed out before. All the rest looks ok.

leeAngry · 2011-09-03 18:23:11

yeah funny thing was.. i was down the hall in the lobby durring that connection.. everything seemed fine so i guess it was the configuration of the router possibly? kind of sucks cuz i wasnt able to get to the bottom of it.. i'm at an extended layover in france and i have 0% packet loss... sorry fellas.. kind of feel like this was a waisted thread.. glad i know of mtr now tho ! thansk anyway everyone for the help.
