Difficulties installing CSI tool

[mirasarkis]

Hello, I am trying to follow the installation steps following the site (https://dhalperi.github.io/linux-80211n-csitool/installation.html).

I am stuck in Step 2, where I have to merge my modifications into Linux ('Tip' section). I am running the Ubuntu 4.2.0-42.49 kernel image to which I cannot associate a correspondent UBUNTU_KERNEL_TAG from http://people.canonical.com/~kernel/info/kernel-version-map.html .

The error I am getting is "Fatal: couldn't find remote ref Ubuntu-4.2.0-42.49 .

One solution would be changing my kernel image and replacing it with another from the above site. I would like to make sure that there is no other solution for this.

Thank you in advance, Mira

Hello Mira and everyone else

I am also trying to install the CSI tool on my laptop but facing the exact same issue as mentioned above. I have installed Ubuntu 14.04.5 with kernel 4.4. I am sure this is unsupported as the website says upto v4.2. As a result I installed Ubuntu 12.04.5 with kernel 3.13.x.x, which is unable to "git pull --no-edit" for some reason. Which version of ubuntu/kernel image should i install in order to make this tool work?

@dpward sir, or anyone else, if possible please try to answer this question about installation. Thanks you.

Hello Akarsh,

In my case, my kernel tag does not correspond to this: UBUNTU_KERNEL_TAG=Ubuntu-x.y.z-x.y.

Other tag formats are defined in the CSItool. You can check these tags by running the following command:

git fetch ubuntu --tags The output would be an exhaustive list of available tags corresponding to ubuntu kernels. To refine your search, you run for example: git tag -l Ubuntu-lts-4.* Note: in my case I have ubuntu 14.04.5 LTS with a kernel version 4.2. The output of this second command is a refined list of tags; at least one should correspond to your version. This tag becomes the value for ${UBUNTU_KERNEL_TAG}

Continue with: >>git pull --no-edit ubuntu ${UBUNTU_KERNEL_TAG}. And it's done! I hope this might help you.

Note: I saw that you downgraded your ubuntu version to 12.04.5. In fact, It was possible to keep the newer version and install a 4.2 core image and headers using this command:

     >>sudo apt-get install linux-generic-lts-wily

And then remove the 4.4 core image and header by first identifying the list of installed images and headers

    >>dpkg -l | grep linux-image

    >>dpkg -l | grep linux-headers

second, delete image/header using:

    >> sudo apt-get purge linux-image-xx linux-header-xx

Regards,

Mira

Thanks for the reply Mira. Right now I have followed your advice and installed 14.04.1 with the kernel version - Linux student 4.2.0-42-generic #49~14.04.1-Ubuntu

So i am trying the "git fetch ubuntu --tags" but git throws the following error -

fatal: 'ubuntu' does not appear to be a git repository fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists.

Can you please check if there is a typo in your answer or point out the mistake that I am doing.

Thank you very much

Make you sure first that you are inside the linux-80211n-csitool directory, where your .git repository resides. Then try to fetch tags using the command "git fetch ubuntu --tags". (I confirm there is no typo in this command).

Note: To build the modified driver, make sure you are also in linux-80211n-csitool directory.

Hello guys

Thanks to mira, I have successfully installed the tool, but having different issue (which seems to be a very common issue and the faq is not helpful in solving it)

1. I have installed the linux csi tool on my laptop which is running 14.04.01 LTS with 3.13.32.57 generic linux kernel.
2. I have also disabled by my AP encryption, its in 802.11 n mode only.
3. I am able to ping successfully on both the router and the laptop from each other.
4. I also have set the rate to the HT rate (54 mbps).
5. Ping is 100% success with zero packet loss.

However the csi file is empty and is unable to log anything.. i have followed all the instructions to the point and been searching for solution for over a week.

I would really appreciate any help in this regards.

Thank you,

Hello I am also having the same problem for collection CSI between my Client and my HostAPd. I have some doubts that maybe I can share:

• On the client: the content of /sys/../macAP/rate_scale_tabel, shows an lq Type HT SISO 40MHz But On the AP: the content of /sys/../macClient/rate_scale_tabel shows lq type legacy. I am not sure if these asymmetric channels are the reason why I cannot log CSI.

• An "80211n station" is mentioned here: https://dhalperi.github.io/linux-80211n-csitool/installation.html. I know the Intel 5300 is capable of doing 80211n, but it can also make 80211 a, b and g. How can I make sure that my client is working in 80211n mode? Is it enough to add the Greenfield mode to the hostapd configuration, to restrict the AP connections to only 80211n stations? On my AP, the content of /sys/../macClient/ht_capa says "ht not supported"?!!!! On my client, the content of /sys/../macAP/ht_capa reveals the ht flags I have set for my AP. Does this mean my AP is doing 80211n wifi but my client is not working as 80211n station?

• When I try to fix the transmission rate on either or both my Client and my AP, my AP freezes and the connection is cut. I don't really understand why?! (Note that the hexadecimal values I am providing are correct!)

• Finally,

Any help please? Thank you in advance

Hello Mira

1. I was able to fix my issues and successfully log csi data. However, I am using a TPLINK router with openwrt, to connect my laptop. Its very easy to change protocol this way.
2. I would also recommend you to use a router for this purpose to avoid unnecessary complications. You can simply use your home router (unplug internet wire).
3. I set my router in 5Ghz HT mode which is 802.11 n and disabled encryption.
4. Set rate any rate higher than 6mbps. I used 54mbps. (feel free to convert that to hexadecimal).

Hopefully, this works for you.

This means that the card of my access point should not be obligatory an Intel 5300 in order to collect CSI data??

Is it enough that only my receiver has the Intel wifi card deployed with the modified iwlwifi driver?

Yes, only the receiver should be a laptop with Intel 5300 chipset to collect the CSI. You can use any router as a transmitter.

@AndroidUnited

How did you router in 5Ghz HT mode ? what are the associated changes in router setting and NIC card setting?

Thanks.

[mirasarkis]

How are you setting up your router?

Are you using hostapd? In hostapd, it is simple..you just need to set the channel to 36 or above! But first, you should verify that your Intel 5300 can send beacons on the 5Ghz frequencies. If you find "passive scanning no ibss" or "no ir" or "disabled" flags when you run "$iw list" command, then it is not possible to make your card work in AP mode on 5Ghz.

Hope this helps! Mira

Hello,

I am also trying to install CSI tool as mentioned in the installation instruction. But in step 2 when i give the command 👍 CSITOOL_KERNEL_TAG=csitool-$(uname -r | cut -d . -f 1-2) i receive an error saying that csitool is not a valid command. I have followed all the steps mentioned. But I don't know how to resolve this issue?

Any inputs would be highly appreciated. Thanks,
