[SOLVED] High ping latency and internet delay on wireless

Hi all,

I have been experiencing weird latency issues in my fresh Archlinux installation. I installed it on a Lenovo Thinkpad X220. The core of the issue is that the wireless connection seems to drop for a given amount of time before restarting as usual. This ends up in very high ping times mixed with lower times. Notice that it happens at random times. I was wondering if there are perhaps any recommendations on this. Some information about the setup:

0. The AP where I am connecting is multiband, but this card can only connect to a single 2.4GHz, hence I renamed the 2.4GHz connection.

1.  Running lsmod | grep  iwlwifi:

$ lsmod | grep iwlwifi
iwlwifi               401408  1 iwldvm
cfg80211              913408  3 iwldvm,iwlwifi,mac80211

2. Running lspci -v

Re: [SOLVED] High ping latency and internet delay on wireless

@zod, disabling IPv6 helped somehow as I can browse without much interruption, so far. The docker seemed to not have any influence. That being said, I do not think is fully solved. To give you an idea of how the ping situation looks like: 

64 bytes from lhr26s05-in-f4.1e100.net (216.58.214.4): icmp_seq=180 ttl=117 time=3724 ms
64 bytes from lhr26s05-in-f4.1e100.net (216.58.214.4): icmp_seq=181 ttl=117 time=2712 ms

64 bytes from lhr26s05-in-f4.1e100.net (216.58.214.4): icmp_seq=187 ttl=117 time=75.1 ms
64 bytes from lhr26s05-in-f4.1e100.net (216.58.214.4): icmp_seq=188 ttl=117 time=1225 ms
64 bytes from lhr26s05-in-f4.1e100.net (216.58.214.4): icmp_seq=189 ttl=117 time=205 ms
64 bytes from lhr26s05-in-f4.1e100.net (216.58.214.4): icmp_seq=190 ttl=117 time=150 ms
64 bytes from lhr26s05-in-f4.1e100.net (216.58.214.4): icmp_seq=191 ttl=117 time=113 ms

Moreover, it seems that whenever there's such a jump, all the responses get back almost immediately. I will give it a few more hours and if the IPv6 disabling lets me browse/install updates and packages without any issues I'll mark it as solve and just keep trying to understand why the ping has such weird delays.

Re: [SOLVED] High ping latency and internet delay on wireless

While you are doing that you might install traceroute  and use it to figure out how your network traffic is moving around.


1) Your description makes it sound like the traffic is queuing up somewhere.

2) That docker has an ip address that seems to be from a commercial vpn provider, so take  a look at your routing table.

Edit: never mind about the docker. It seems as that address is default for docker.

Edit1: While i'm thinking about it, you had multiple ipv6 adresses interfaces(?) so you might want to sort that out...if you need ipv6.

1) Your description makes it sound like the traffic is queuing up somewhere.

Thanks! 1) sounds about right. I do not see anything weird on  the traceroute, but perhaps someone more experienced can tell me if they see anything particularly strange:

Regarding the IPv6 I was wondering why there were many interfaces/addresses, it doesn't make sense as I only have a single card and I have not created any additional virtual interfaces that I know of. I do not think that I will be using IPv6 right now, but if I run into a situation where I need to, I will probably take a look at the wiki to configure it properly. If you have any documentation handy feel free to post it in the post.

So far no issues on browsing/package download, so I think I may be closing this issue after 48 hours if I do not experience any issues after restarting the laptop or whatever. Thanks for the help!

Edit: Nevermind that, the issue is not fixed yet, although it seems to be a lot less without IPv6 and it does seem that the packages are getting stuck somewhere: new traceroute:

Re: [SOLVED] High ping latency and internet delay on wireless

Use mtr to ping. some sites/firewall block/drop UDP ping packet.

# pacman -S mtr
$ mtr --tcp IPADD
$ mtr --udp IPADD

Use mtr to isolate if the packat drop is on LAN or on WAN. Do you also have packet drop using ethernet cable direct connect to your router?

Re: [SOLVED] High ping latency and internet delay on wireless

So to summarize new findings:

1. It would seem that the queue hangup occurs at the gateway for TCP packages. I am not too concerned about UDP packages. I guess the question would be then if it's a problem of the router I am using or if it is something in the configuration of the NIC in Archlinux. The mtr: 

Host           Loss%   Snt   Last   Avg  Best  Wrst StDev
 1. _gateway    66.2%   596  8191. 2716.   3.1 9880. 3351.
 2. (waiting for reply)    
 3. (waiting for reply)    
 4. asd-tr0021-  7.2%   596  301.5 1290.  15.8 9891. 2510.
 5. nl-ams14a-r  6.7%   596  196.6 1327.  14.1 9965. 2539.
 6. 74.125.146.  7.1%   596   84.8 1271.  13.4 9998. 2493.
    10ge-1-4.cr1.ams2.baseip.com                         
 7. 108.170.241  7.6%   596   19.5 1258.  14.9 9896. 2452.
    216.239.56.129
    108.170.241.225        
    216.239.51.  6.4%   595   25.0 1342.  15.2 9986. 2549.

2. disabling IPv6 on the networkd config file for the wlan interface did help.

3. There is no packet loss on a wired connection.

If anyone may have an idea on this, that would be highly appreciated

Re: [SOLVED] High ping latency and internet delay on wireless

Yes the problem seems inside LAN. If you can test with ethernet cable direct connect to your router that would be a good idea. better yet, use archiso liveUSB to perform the test.
inside archiso liveUSB

# pacman -Sy
# pacman -S mtr

Re: [SOLVED] High ping latency and internet delay on wireless

And reboot the router, just in case.

Re: [SOLVED] High ping latency and internet delay on wireless

Ok, after doing the liveUSB test and the ethernet cable test no packet loss with mtr. So I am almost convinced is something from the configuration itself. I should probably check the configuration files in the liveUSB to see if there's anything that stands out.

Edit: Seems to be the router. I'll play more with the configurations on both sides. I am keeping this post open for another day.
