DNS seems to stop working after approximately 5 minutes

infmachine · February 24, 2017, 6:08pm

Hi,

Since I own a router that does not allow me to change DNS settings (comcast/xfinity), setting up the pi-hole as per the instructions was out of the question. So what i did was create an AP out of a raspberry pi and set up the pi-hole software on it. Unfortunately I'm having some problems with the set up.

Everything seems to work fine for about 5 minutes and then I cannot load any web pages, ping any sites, "dig" any addresses etc. But, when I disconnect from the AP and then re-connect , everything starts working again. My guess is that there is a renewal of some sort of setting that goes awry in this 5min time frame. I don't know if anyone has run into this sort of problem or even posted questions about it as I'm having problems formulating the question properly let alone a successful google/forum search.

Please let me know what information about the setup I can provide to help diagnose this problem.

Thanks

Could you tell me why you don't use the pihole DHCP server?

In case you didn't knew. If you use the pihole DHCP server it will automatically send the IP adress of your RPI to your clients. This way you don't need to set up a new AP.

However if you want to do it this way, you could make a debug token (with pihole -d).

Not sure what you are suggesting I do here. I was under the impression that i was using the DHCP server. How do i know if i'm using it or not? If i'm not how do i use it? Here is the output for pihole -d that you requested. This was taken during the time where the internet was working on the clients(s) connected to the AP.

I'm not sure if i correctly understood what you done. Please correct me if i'm wrong. You set up pihole and a new AP because you can't change the DNS adress in your router. And on the new AP you set the DNS server to pihole.

Pihole has a own DHCP server so you don't need to use the DHCP server from the AP you set up.

Since dig works correctly in both debug logs i'm guessing that the problem is the AP you set up. Could you tell me what software you used and how you did the setup?

Note:

You don't need to post the debug logs here. You can upload them to a secured webserver to which only 6 people (the developers) have access to. That way your informations are more secure.

infmachine · February 24, 2017, 8:56pm

This is my setup:

Raspberry pi Zero with a 4-port USB hub and two EDIMAX 2.4GHz wifi adapters. I used hostapd and dnsmasq to set up an AP which uses the 1st wireless adapter's internet connection. ALL directions online are written for people using eth0 (internet connection) to wlan0 ( the AP ). What i've done is use wlan1 (connected to internet) to wlan0 (the AP). It works fine without pihole installed on it. But, once I installed pihole I started having these connection issues.

Thanks for the tip about the logs. Hopefully there isn't anything too bad in them for them to be posted on here. Unfortunately once connection goes out there is no way to upload the 2nd log because the 1st one goes through without a problem. Also, i posted them here not knowing if you had access to them once they were uploaded to wherever.

If you would like any other logs/config details/etc. please let me know!

I think the problem may be in the networking. Looking at the debug from when the internet appears to be non-functional, we do a test to see if the Pi can reach the internet. The results show that the Pi-hole is able to connect to the internet:

;; ANSWER SECTION:
doubleclick.com.	299	IN	A	172.217.3.14

That snippet shows that a query to Google's DNS (8.8.8.8) responded with an answer in 143ms. So the Pi-hole is still able to talk to Google.

When the clients lose connection to the network, can they even ping the Pi-hole?

DanSchaper · February 24, 2017, 9:05pm

What software are you using to server DHCP addresses to the clients? And is the Zero a DHCP client and server (depending on the interface?) Raspbian uses DHCPCD for static addressing, and that may be in some way causing problems...

infmachine · February 24, 2017, 9:29pm

First off I have to apologize. I did a quick test of the setup without the pihole software installed and made the incorrect assumption that everything was fine and working. Unfortunately this is not the case. I have sort of found the problem in the syslog which states :

Feb 24 16:15:58 raspberrypi hostapd: wlan0: STA 18:cf:5e:96:c5:9d IEEE 802.11: disassociated <--- the problem

Seems like i'm in the wrong place to be asking how to fix this. Unless someone else here has run into such an issue. Otherwise, it's back to google I go. I will report back on how to fix this issue (if i find a fix) because it seems like this is what is causing the outage and not anything being done by the pihole software.

DanSchaper · February 24, 2017, 9:37pm

Are the two adapters on different channels?

infmachine · February 24, 2017, 10:00pm

Yes the two adapters are on different channels as far as I can tell.

@infmachine ,
Sounds to me you got bitten by wifi power saver mode.
Can you do below to check settings for wlan0:

grep '' /sys/module/$(readlink /sys/class/net/wlan0/device/driver/module | xargs -n 1 basename)/parameters/*

And below one for wlan1:

grep '' /sys/module/$(readlink /sys/class/net/wlan1/device/driver/module | xargs -n 1 basename)/parameters/*

Look for "power" & "enusbss" settings.

I have noticed the setting and applied the fix posted around the internet concerning making a .conf file w/ desired (turn the mode off) settings. Unfortunately using the method described @ https://www.raspberrypi.org/forums/viewtopic.php?t=61665 did not fix the issue.

deHakkelaar · February 25, 2017, 4:15pm

@infmachine ,
i did not read the whole forum post but you only have to do one thing to switch off "rtw_power_mgnt=1":

echo "options 8192cu rtw_power_mgnt=0 rtw_enusbss=0" > /etc/modprobe.d/8192cu.conf

And reboot and check again with the grep.... command if things have changed.
But if thats not it, i have no clue whats bugging your setup.
