500 - Internal Server Error on /wireless/radio0.network1

amq · October 7, 2016, 10:42am

How to replicate:

switch radio0 to 2.4Ghz

The card itself works, but I can’t open the configuration in luci.

My /etc/config/wireless, just in case:

config wifi-device 'radio0'
        option type 'mac80211'
        option country 'CZ'
        option path 'platform/soc/soc:pcie-controller/pci0000:00/0000:00:02.0/0000:02:00.0'
        option txpower '15'
        option hwmode '11g'
        option channel '13'
        option htmode 'HT40'
        option noscan '1'

config wifi-iface
        option device 'radio0'
        option network 'lan'
        option mode 'ap'
        option encryption 'psk2+ccmp'
        option key 'censored'
        option ssid 'censored'

config wifi-device 'radio1'
        option type 'mac80211'
        option country 'CZ'
        option hwmode '11g'
        option path 'platform/soc/soc:pcie-controller/pci0000:00/0000:00:01.0/0000:01:00.0'
        option txpower '15'
        option channel '13'
        option htmode 'HT40'
        option noscan '1'

config wifi-iface
        option device 'radio1'
        option network 'lan'
        option mode 'ap'

I reported this issue on Turris 1.1 as well, but no respond so far for it.

Ouch… that does not speak in favor of cz.nic promising life long support…

I don’t have recent experience with linux config but as far as I know if you want to use 40 Mhz channels you must set lower channel and the other will be set “automaticaly” for most of devices I have in hands.

i.e. - channel 1 for 1&5(or 6 ); 5 for 5&9(11); etc

if you set 13 there is no upper channel left for 40 Mhz so you should set 9 or 10 or something like that, no?

and I’m really not sure if it’s “safe” to use two devices on the same hwmode

[quote=“amq, post:1, topic:970”]
config wifi-device ‘radio0’
option hwmode ‘11g’
…
config wifi-device ‘radio1’
option hwmode ‘11g’[/quote]

Luci still doesn’t work for radio0 with 2.4 GHz even if I set the channel to 6 and completely remove radio1.

MiKe · October 8, 2016, 12:05pm

and the radio0 is not 5GHz only?

amq · October 8, 2016, 12:08pm

No, it works perfectly on 2.4 GHz. It is faster than radio1 too.

MiKe · October 8, 2016, 12:13pm

I don’t have my omnia yet. Isn’t there any log for LuCi with detailed info about the error?

Pepe · October 8, 2016, 12:26pm

LuCI will give you blank page or error 500, nothing more.
He should look into syslog ( I mean: /tmp/log/messages )

amq · October 8, 2016, 12:31pm

Nothing in system log.

In /tmp/log/lighttpd/error.log

In this case would be better to write this to: tech.support(at)turris(dot)cz

Dangar · November 5, 2016, 9:18am

I can confirm that I have same issue.
The only way how to get /wireless/radio0.network1 working again is go to Turris Omnia web interface and switch radio back to 5GHz (or change config files by uci).

After that is /wireless/radio0.network1 accessible again normally. You can change any settings, e.g. switch back to 2.4GHz, modify settings according to your needs and save & apply changes. After saving the address /wireless/radio0.network1 returns 500 again.

nerdpunk · November 5, 2016, 9:46am

you shouldn’t switch the 5 GHz card to 2.4 GHz unless you removed the diplexers and are using dedicated antennas…

dpdrown · November 5, 2016, 8:27pm

I get this with my card on 5GHz. I tracked it down, and it’s already fixed upstream, just waiting for the updated binaries: https://github.com/CZ-NIC/turris-os/issues/10

FWIW, the change that makes my TO Luci radio0 edit page report “500 - Internal Server Error” was doing the uci commits to change the wifi’s country setting:

uci set wireless.radio0.country='US’
uci set wireless.radio1.country='US’
uci commit wireles

Prior to that, I had radio0 doing 5 GHz and radio1 doing 2.4 Ghz with no problems.

As reported in https://github.com/CZ-NIC/turris-os/issues/10, a fix has been committed so iwinfo’s txpowerlist querry will no longer cause a seg fault, leaving pour Luci in the lurch.

My TO just went through an automatic software update this morning. After the update, my TO’s Luci still puts up “500 - Internal Server Error” on the radio0 edit page. Both wifi’s are working as they should. Just can’t get to Luci’s edit page on radio0.

Looking at /usr/lib/opkg/status entries for iwinfo and libiwinfo:

Package: iwinfo

Looks like the fix wasn’t in this drop. Is that correct?

That is correct, 2015-06-01-ade8b1b299cbd5748db1acf80dd3e9f567938371 is still a broken version.

It seems that fix didnt make it to release.
I will ask on IRC what happened

Comodore125 · November 15, 2016, 10:35am

So. Hold long to wait?

miska responds: "Well for a month we hope to do release containing all bugfixes really soon but something that needs fixing always pops up :-/ "

Today it was pushed to omnia-stable so we will receive it soon
