DietPi-Config | Add ability to set regulatory domain (WiFi)

k-plan commented 8 years ago

@Fourdee

we need a option, like in the new raspi-config version, to get e.g. RPi 3 Wifi Channel 12+13 working with Kernel 4.4x ("unstable").

REGDOMAIN=DE

Hint: Tested on RPi 3, Odroid C1+ and C2. Working as well. If setting Regulatory Domain to the correct country code, and the same as the Access-Point (WiFi Router) I will get a higher bandwidth and a more solid connection.

Country codes: https://en.wikipedia.org/wiki/ISO_3166-1_alpha-2

Current country code

iw reg get | grep -m1 'country' | awk '{print $2}' | tr -d ':'

Menu select common codes -GB -RU -US +manual entry option etc

Location: Network Options: Adapters > Wifi ? (menu too big already?, convert to scrollable menu?) Network Options: Adapters > WiFi Country?

Merge Menu_WifiHotspot into Menu_NetworkAdapters_Wifi() , create whiptail array to only show required menu options, depending on mode. Allows for https://github.com/Fourdee/DietPi/issues/311. Possible issue with top stats being too many lines,

@Fourdee

Location: Network Options: Adapters > Wifi ? (menu too big already?, convert to scrollable menu?) Network Options: Adapters > WiFi Country?

Difficult question. Both have pros and cons. If scrollable, someone can miss it. If it will be a new list point, it will blow up the list. May be a issue, if you must have to put in new options later.

Merge Menu_WifiHotspot into Menu_NetworkAdapters_Wifi() , create whiptail array to only show required menu options, depending on mode. Allows for #311. Possible issue with top stats being too many lines,

Hmm ... it's the same here.

Menu select common codes -GB -RU -US +manual entry option etc

Hmm ..

for 2.4 GHz (802.11b/g/n) it will be better:

Menu select common codes -GB -US -JP +manual entry option etc.

for 5 GHz (802.11a/h/j/n/ac) it will be better:

Menu select common codes -GB -US -CN +manual entry option etc.

WLAN Frequency

Can you please build a version with all possible option and check in via testing branch, so we can have a look?

Fourdee commented 8 years ago

@k-plan Thanks for the extra info :+1:

Started on this today. I havn't done any real "programming" for a while, so little rusty lol. Will let you know when its available for testing.

k-plan commented 8 years ago

@Fourdee

your screenshot is looking very handsome.
2.4 GHz (802.11b/g/n) is a good choice to start. (RPi 3 build-in WLAN module)

Fourdee commented 8 years ago

CRDA was not applying our saved setting during reboots, reverts to 00:

# - Apply to system configs, for reboots
echo -e "REGDOMAIN=$wifi_country_code_target" > /etc/default/crda
echo -e "options cfg80211 ieee80211_regdom=$wifi_country_code_target" > /etc/modprobe.d/cfg80211.conf

Fixed :)

Fourdee commented 8 years ago

@k-plan Uploaded to testing branch.

For now, I've just added the ability to change WiFi country code when running in non-AP mode. Also been playing around with the menu code (select "change mode") to resolve the height issue. Country Code is available in Network Options: Adapters > Wifi

Commit: https://github.com/Fourdee/DietPi/commit/49aa00bb3b272e10ec723a36cff9632dd52da332

I'll work on the AP mode menu next.

EDIT: And test 5ghz country code support for non-AP mode.

Turns out I do not own a 5ghz capable USB WiiFi dongle, and the RPi 3 is 2.4ghz only. :( lol

I might have to purchase one of these: http://www.edimax.com/edimax/merchandise/merchandise_detail/data/edimax/global/wireless_adapters_ac600_dual-band/ew-7811utc

Good list of RPi USB WiFi adapters: http://elinux.org/RPi_USB_Wi-Fi_Adapters

Fourdee commented 8 years ago

As far as I can tell, country code iw reg set has no effect on Hostapd.

iw reg set US
Set hostapd channel to 13
Restart hostapd and networking services. Even did a reboot. iw reg get = US
Hotspot still available on channel 13.

Fourdee commented 8 years ago

Hostapd:

I can not get 2.4ghz N (150mbit) to work on hostapd with driver=rtl871xdrv and :

Bus 002 Device 002: ID 7392:7811 Edimax Technology Co., Ltd EW-7811Un 802.11n Wireless Adapter [Realtek RTL8188CUS]

Tried using:

hw_mode=n
wwm_enabled=1
ieee80211n=1

Any of these option prevents hostapd service from starting, no error codes/info from systemctl status hostapd -l

Tried with RPi 3

interface=wlan0
#driver=none
ssid=DietPi-HotSpot
hw_mode=g
channel=3
macaddr_acl=0
auth_algs=1
ssid=DietPi-HotSpot
wpa=2
wpa_passphrase=dietpihotspot
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP
rsn_pairwise=CCMP
#wwm_enabled=1
ieee80211n=1

Seems to work with N (72mbit max on this device):

So as far as I can tell, Wireless N support is only available for devices that use the driver=nl80211

@Fourdee

wow, you are to quick for me. 😄
Sorry, have to catch up.

Starting now with gitbranch=testing

Fourdee commented 8 years ago

@k-plan I broke the RPi 3 hotspot. Turns out the internal BCM does not like any driver unless its disabled #driver=none. I've sent a new commit: https://github.com/Fourdee/DietPi/commit/746fa36b3fa3e2027527c625f12560560833936d you just need to grab dietpi-software if you are going to test RPi 3 with hotspot.

is it possible we missed something (packet, config, db ..) ?

xenfomation commented 8 years ago

My brain has been squished from LLMP, BUT I wanted to ask both of you --

Based on the dietpi-software and configure options:

Are we caching @k-plan's setting or is cleaned up from /tmp/.... ?
If we aren't caching this, would a work using /etc/rc.local + boot scripts for services to SET this be too... hackish?
As for N networking, I've seen similar issues as you found @Fourdee -- good catch and reminder!
I run N and can test this tomorrow morning as I have several routers and can wait till the family is snuggled in bed to confirm the 5Ghz range, etc
OR as I just realized, boot.ini could carry/source this in

The angle I am coming from is ensuring this is set as close to pre init 3 run-level as possible and also leaving a config option cache to avoid the kick back to !DE, but 00.

Thanks again for everyone's time to listen to my ideas as the code will come, oh trust me, but group work is far superior to a myopic approach!

Cheers to you both!

KUDOS for getting on the right track!!!

https://en.wikipedia.org/wiki/ISO_3166-1_alpha-2

While @k-plan is at the core of it, I was looking into using "iw reg set DE" before the physical interface tries to come alive...

Nice work and I will keep digging into this as it should take no longer than 15-30 minutes.

xenfomation commented 8 years ago

Despite the infinite claims for Debian/Ubuntu, I regret to report that /etc/default/crda does not promote regional codes as it should.

I was able to repeat @k-plan's issue of set manually, reboot, run iw reg get only to see "00: DFS-UNSET"

Now, as a cludge right now:

vi /etc/rc.local

#!/bin/sh -e
iw reg set DE
/DietPi/dietpi/dietpi-services start
/DietPi/dietpi/dietpi-banner 0
echo " Default Login:\n Username = root\n Password = dietpi\n"
exit 0

On reboot, I obviously retain this good config @k-plan needs:

iw reg get
country DE: DFS-ETSI
        (2400 - 2483 @ 40), (N/A, 20), (N/A)
        (5150 - 5250 @ 80), (N/A, 20), (N/A), NO-OUTDOOR
        (5250 - 5350 @ 80), (N/A, 20), (0 ms), NO-OUTDOOR, DFS
        (5470 - 5725 @ 160), (N/A, 26), (0 ms), DFS
        (57000 - 66000 @ 2160), (N/A, 40), (N/A)

So, looking to move this type of param-set/config option into native DietPi territory -- will post shortly.

xenfomation commented 8 years ago

I have a work around (that could become a fix) right now for retaining the regulatory code desired. I do not have the menu items updated to inject this data for the DietAdmin (at present) I do not have any real error handling, default values, etc -- it tries to work with what is defined.

Environment

I am running PI 2 B + DietPi v117 CRDA, it's "default config file", clean environment, etc

Work-Around/Partial Fix:

Common, common, common problem
/DietPi/config.txt : added Wifi_REGION=XX variable
/DietPi/dietpi/boot : loads this and during normal service startup, grabs the Wifi_REGION variable as to ensure iw reg set $Wifi_REGION is set at the right time during boot
Testing was done for GB, DE, and 00/US
I didn't even have to set anything -- I rebooted and the dietpi init/boot service did the rest for me

DE output before and after reboot

iw reg get country DE: DFS-ETSI (2400 - 2483 @ 40), (N/A, 20), (N/A) (5150 - 5250 @ 80), (N/A, 20), (N/A), NO-OUTDOOR (5250 - 5350 @ 80), (N/A, 20), (0 ms), NO-OUTDOOR, DFS (5470 - 5725 @ 160), (N/A, 26), (0 ms), DFS (57000 - 66000 @ 2160), (N/A, 40), (N/A)

GB output before and after reboot

iw reg get country GB: DFS-ETSI (2402 - 2482 @ 40), (N/A, 20), (N/A) (5170 - 5250 @ 80), (N/A, 20), (N/A) (5250 - 5330 @ 80), (N/A, 20), (0 ms), DFS (5490 - 5710 @ 160), (N/A, 27), (0 ms), DFS (57000 - 66000 @ 2160), (N/A, 40), (N/A)

Code Changed, but not checking in until all can look and provide feedback

/DietPi/config.txt (needs to be populated, read, and maintained by dietpi-config, etc) This will also ideally feedback into the menu system for COUNTRY as to ensure no more loss of COUNTRY Alpha-2 Characters:

#-------Wifi Country/ISO Code--
Wifi_REGION=DE

/DietPi/dietpi/boot (minor error checking to ensure Wifi_REGION is not null, commented out, etc) This is merely to follow the lay of the land; ensuring that as services are started, regulatory country codes are applied for Wifi (under Run_Init )

                #See if Wifi_REGION is set and if so, apply it via iw reg set
                Wifi_REGION=$(cat /DietPi/config.txt | grep -m1 '^Wifi_REGION' | sed 's/.*=//')
                iw reg set $Wifi_REGION

Nothing special, gets the job done and can be leveraged by the dietpi config utilities (as mentioned before) as long as all approve.

I hope this helps, @Fourdee as maybe it isn't the cleanest solution, but with an hour - 2 hours of integrating this with the WiFi COUNTRY setting (check, create, update dietpi data, as well as updating the native /etc/default/crda file) -- I do believe this will work as a fix.

I look forward to the feedback and pardon the delay -- had to swim through SD cards to start fresh.

Fourdee commented 8 years ago

@xenfomation

Based on your ideas :+1: , I'am going to do the following:

/DietPi/dietpi.txt | Add global var for WiFi_CountryCode=
/DietPi/dietpi/boot | Add iw reg set $WiFi_CountryCode

This will allow users to declare their country code prior to first run. Also ensures country code will always be applied during boot. I've tested iw reg set in boot script, gets applied.

Fourdee commented 8 years ago

Decided to make a function script for applying/changing WiFi country code, so we can use it in multiple scripts.

Following applies Country code to system. with value stored in dietpi.txt if set wifi_country_code= :

/DietPi/dietpi/func/dietpi-set_wificountrycode

Following changes value in dietpi.txt, known system configs, and applies new country code to system

/DietPi/dietpi/func/dietpi-set_wificountrycode GB

this function is called during boot, and when changing country code in dietpi-config

@Fourdee -- slick! Especially with it being scriptable. Nicely done and for miscellaneous trivia, if they don't know their country code.... 00 works as a default ;-) Kinda breaks their own ISEC/ISO standards, but I am glad you knocked this out!

Fourdee commented 8 years ago

@xenfomation Yep, if only the system called /etc/default/crda during boot and used the value set there. Maybe there's something we missed.

Either way, this function script was needed so we can call it across multiple other scripts, based on a global country code value set in dietpi.txt

xenfomation commented 8 years ago

Indeed! Sad thing about it is... I haven't found anything to even imply it was missed by anyone. My reasoning for this is many have complained about this and it coincides with the whole "systemd" nonsense (IMHO).

I should have pull requests (sorry about the last two!!) to "testing" for #295 and #246 in a few hours for your review. This means I can get back to LLMP, but make a double-random sweep for CRDA. I mean, the three of us clearly see dmesg invoking CRDA, so yes: What are you not doing or doing ad-hoc, Mr. Debian?

Example from the maintainer and someone with the same questions as us! https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=721865

However, this is why I think nothing is missed (you have it all in DietPi!): http://raspberrypi.stackexchange.com/questions/40738/jessie-cfg80211-calling-crda-to-update-world-regulatory-domain

@Fourdee

tested your new version with /DietPi/dietpi/boot for changing WiFi country code with a Edimax EW-7612UAn V2 (2.4 GHZ - 802.11b/g/n - 300Mbps)

Set via dietpi-config country code 00 -> DE (readout) ==>> reboot = DE (readout) setting -> CN (readout) ==> reboot = CN (readout) setting -> US (readout) ==>> reboot = US (readout) (I spare the log output here)

It works, nice. 👍

Get it on work is the first time a little tricky. The 2.4 GHz USB adapter was wlan0 before, so you have to plug 5 GHz USB adapter in / out and have to enable-disabel-enable WiFi network via dietpi-config because it is now wlan1. No big deal. You can as well edit /etc/network/interfaces by hand, but I want to test, it it will work without doing this.

But setting, reboot, switching country code works fine as well! 👍

Here some fun. I hope, the bottleneck is USB 2.0 Port of the C1+ :

😄

And the 802.11ac AC1200 Dual-Band USB 3.0 Adapter is really chatty in dmesg !

@k-plan Thanking you for in-depth testing and results as always :+1:

And the 802.11ac AC1200 Dual-Band USB 3.0 Adapter is really chatty in dmesg !

Holy cow lol. Looks like its reporting everytime it switches from powersaving modes.

I'll mark this as closed. I will take a look into https://github.com/Fourdee/DietPi/issues/311 next (which is a continuation of code changes here) and see what we can do.

Nice find. If this works with all adapters, would be a better solution than the current:

echo -e "options 8192cu rtw_power_mgnt=0" > /etc/modprobe.d/8192cu.conf
echo -e "options 8188eu rtw_power_mgnt=0" > /etc/modprobe.d/8188eu.conf

I'll have to give it a test with a few devices. If it doesn't break WiFi for the devices we have, cant see any reason not to add it in.
