very slow wifi Intel Wireless-N 1000
very slow wifi Intel Wireless-N 1000
I've noticed that my wifi connection is significantly slower than my wired connection. Obviously wired is always faster, but when I boot in to windoze or use Mac, the difference between wired and wifi is negligible. I'm running Debian 8 testing on a Lenovo X201 with Intel Corporation Centrino Wireless-N 1000 [Condor Peak] network card. Could somebody please advise on how to resolve the problem?

Re: very slow wifi Intel Wireless-N 1000
Great, thanks for the lead, but none of that seems to have helped. My wired speed is still around 5-6 times faster than wifi....My wired connection is getting around 44 Mbps, whilst the wifi is managing only around 11 (at best, but sometimes it's down to ~6Mbps). Under windoze, however, wifi is moving at around 30 Mbps.Head_on_a_Stick wrote:http://forums.debian.net/viewtopic.php?f=16&t=121696

Re: very slow wifi Intel Wireless-N 1000
It would be helpful if you could explicitly list all the things you have tried.
For example, is the card's power management enabled?
For example, is the card's power management enabled?

Yes, of course, have tried:Head_on_a_Stick wrote:It would be helpful if you could explicitly list all the things you have tried.

options iwlwifi 11n_disable=8 # enable antenna aggregation
options iwlwifi swcrypto=1 # enable software encryption - helps performance on some intel cards
I also tried putting

ifconfig wlan0 power off
Finally, I did

Re: very slow wifi Intel Wireless-N 1000
First, the command should be "iwconfig wlan0 power off", not "ifconfig....." (I just noticed that error and mentioned it in the referred thread).xedni wrote:I also tried puttingin /etc/pm/power.d/wireless, although I'm not sure how to make it executable, as suggested by v&n.Code: Select all
ifconfig wlan0 power off
Second, files are made executable with 'chmod +x <filename>' command. For example -
Code: Select all
sudo chmod +x /etc/pm/power.d/wireless
Thirdly, the power management already appears to be 'off' in iwconfig output. So the above may not be needed. We shall need to see more settings to verify where the culprit may be. Can you run a script and post its report file please? That should give us most of the required info in one go. The script and the method to download/run it is mentioned here : http://forums.debian.net/viewtopic.php?p=579154#p579154
PS: Just as a statutory warning, you should never run unknown scripts. Run them only if you know what exactly they are going to do. The one mentioned above just collects wireless related info and puts it in a report file (wireless-info.txt) while filtering out all the sensitive info (wifi password, MAC IDs etc.). Personally I trust it, but the statutory warning still stands.

Re: very slow wifi Intel Wireless-N 1000
Quoting the parts that look significant to me -
1. The "11n_disable" parameter is still set to "0" which is obvious because it is default and nowhere else any other mode is forced. So I suggest you create a conf file to force mode '8' -
Reboot and see if your connection is good now (check connection speed in 'iwconfig').
2. Your laptop is not using the 'iwlmvm' driver (is using 'iwldvm' instead), so the 'iwlmvm.conf' file is needless (not causing any harm, but is needless). I suggest you delete it to eliminate unnecessary confusion/complexity -
3. I keep seeing those "..invalid WMM params" warnings in dmesg and usually they don't seem to cause any troubles. But sometimes I believe they can. So check your router's settings for QoS/WMM, and try changing the status of the WMM feature if the router's interface provides the option to enable/disable it. Usually turning it off helps, but some users have reported they need it to get optimal performance.
If these don't seem to help, please run the script again (with root privileges), after making above changes, and post back its fresh report. Running it with root privileges is recommended here since the script was originally created for Ubuntu, while some of its presumed 'basic' commands need root privilege in Debian.
Oh, and make sure you run it with ONLY wireless connected. Preferably no ethernet connection in picture. Of course no need to run if any of the suggestions proposed above fix the issue.
Now suggestions for now, try one at a time, moving forward (without reverting the previous change) as and if required -xedni wrote:Code: Select all

Re: very slow wifi Intel Wireless-N 1000
I' ve set it to mode 8 and deleted iwlmvm.conf, although my router doesn't seem to have an option to set QoS/WMM. Unfortunately I haven't noticed any changes in the connection speed

Re: very slow wifi Intel Wireless-N 1000
EDIT: First off, please edit your post above to change the 'quote' tags to 'code' tags for the output part. As you can see, the 'quote' tags cannot preserve the formatting of the report. Remember to use 'code' tags for outputs in future.
----------------------
Hmm.. I was hoping to see some outputs in 'iwlist' section. Do you get any errors if running it manually? -
Please post back whatever errors or output it returns.
For now, please try some further changes in the router/access-point -
1. Try changing the channel to 1. With no output from iwlist scan, I can't tell if it would be the best channel for you. So please also try fixing the channel to 11 or 13 if ch.1 doesn't make any difference. You can install and run package 'wifi-radar' (a gui tool to create available signal profiles and monitor their quality) to check which of the channels are least congested and have best signal quality.
2. If your AP(access-point) is using 'auto' or '20/40 MHz auto' mode for channel bandwidth, please try fixing it to 20 MHz only mode. So now both the channel and the bandwidth should be 'Fixed', not set to 'auto'.
Reboot the router after saving the changes, connect again and see if the connection is any better. If it is still the same, try adding another parameter in the conf file -
This will add the "bt_coex_active=N" parameter to the existing conf file. It will disable a feature of the driver that is supposed to help wifi connection quality, but sometimes actually causes problems instead (more often in older versions, not required for a long time now in the latest versions, so it is basically just a shot in the dark).
Reboot, recheck the connection. If still the same (less than 24 Mb/s in iwconfig), try adding yet another parameter 'swcrypto' -
This will shift the workload of packet encryption from hardware (wifi chip) to software (driver/OS). Again, this is something that has not been required for a long time in the threads I've troubleshooted (in fact causes more troubles sometimes with latest versions), but is worth a try. Reload the driver or reboot to check the performance again.
If none of this makes any difference, try a forced speed and report back if you get any errors -
If it sticks (will show up in iwconfig), check if the connection is stable. Some other supported speeds worth trying could be 11M (to be tested only if 24M makes the connection unstable), 36M, or 48M. There are also higher speeds corresponding to N mode, but a forced speed is really not the way to go. It is just for a test to see if the connection can survive higher speeds.

Re: very slow wifi Intel Wireless-N 1000
Looks like you ran the command when wifi was disabled -
Please try again when the wifi is connected. The result will help us see if something in the router/access-point can be done to optimize the connection quality.xedni wrote:wlan0 Interface doesn't support scanning : Network is down

Re: very slow wifi Intel Wireless-N 1000
Now this happens when the interface is active, but is already busy in scanning the network. Once that is done and a connection is established (or if the interface gives up and sits idle (not inactive)), it should return some results.xedni wrote:wlan0 Failed to read scan data : Resource temporarily unavailable
I must say that this is the first time I've seen iwlist requiring so many retries... makes me wonder if this could be part of the problem.

Re: very slow wifi Intel Wireless-N 1000
I think my current level of experience and thus the suggestions based on it probably end here ("probably", because I'm posting in a hurry, so I maybe overlooking something). It seems troubleshooting your case may require some further research, for which (despite it being a very interesting activity for me) unfortunately I'm currently a bit short of time.xedni wrote:Unfortunately none of the above seems to have had an effect.
So I encourage you to do the research and experiments yourself, and keep us posted of the progress. Hope I or someone else will be able to post something more useful later.
The "research" means searching the internet making the symptoms and more importantly, the error messages as your 'search keywords', read the result pages and see if they seem same, similar or otherwise relevant to your case and implement the suggestions if they do seem relevant (blindly following suggestions can make the problem worse, so feel free to ask here if you are in confusion).
Of course do this only if you have the time and interest to do so.
Sorry I couldn't be of more help at this time. Hope someone else may come along with more suggestions. One of our best troubleshooters - Head_on_a_Stick - is already on this thread (not to drag you, HoaS, but I'm sure you're watching us with curiosity ).

It seems troubleshooting your case may require some further research, for which (despite it being a very interesting activity for me) unfortunately I'm currently a bit short of time.xedni wrote:Unfortunately none of the above seems to have had an effect.
So I encourage you to do the research and experiments yourself, and keep us posted of the progress. Hope I or someone else will be able to post something more useful later.
The "research" means searching the internet making the symptoms and more importantly, the error messages as your 'search keywords', read the result pages and see if they seem same, similar or otherwise relevant to your case and implement the suggestions if they do seem relevant (blindly following suggestions can make the problem worse, so feel free to ask here if you are in confusion).
Of course do this only if you have the time and interest to do so.
Sorry I couldn't be of more help at this time. Hope someone else may come along with more suggestions. One of our best troubleshooters - Head_on_a_Stick - is already on this thread (not to drag you, HoaS, but I'm sure you're watching us with curiosity ).

I bow to your superior expertise in this bailiwick -- I can add nothing useful.
Sorry OP
