2023-02-24 08:52:16 +0000 commented answer AP logs strong wifi noise signal

Somehow it's strange as the AP is located in a cellar where it should be unlikely to receive strong noise signals.

Ok I feared the packet capture can't tell me anything ... Still thanks for you explanation +1

In the logs of my AP I see many log messages about a strong noise signal detection on channel 36.

23.02.23 21:02:21 [fritz.powerline] Eine sehr starke Störquelle wurde auf Kanal 36 (Frequenz 5.180 GHz) erkannt, automatischer Kanalwechsel ausgeführt.

23.02.23 21:02:10 [fritz.powerline] Eine sehr starke Störquelle wurde auf Kanal 36 (Frequenz 5.180 GHz) erkannt, automatischer Kanalwechsel ausgeführt.

23.02.23 21:01:59 [fritz.powerline] Eine sehr starke Störquelle wurde auf Kanal 36 (Frequenz 5.180 GHz) erkannt, automatischer Kanalwechsel ausgeführt.

23.02.23 21:01:40 [fritz.powerline] Eine sehr starke Störquelle wurde auf Kanal 36 (Frequenz 5.180 GHz) erkannt, automatischer Kanalwechsel ausgeführt.

After switching to channel 40 the log messages don't appear anymore.

I recorded a trace of the AP's Wifi interface: https://1drv.ms/u/s!AphLkdj_V9pOqAYTT...

I wonder if somebody can see any hint in the trace what could be the cause of the noise signal (I do not see anything)?

2022-09-24 12:40:52 +0000 marked best answer DNS query fails - did the query reach the router?

Users did report that visiting a web site via iPad/Safari fails. I found out that the reason a failing DNS query. This issue only applies to some websites (for others it works). Visiting one of the "failing" sites at the same time using an iPhone works.

One of the failing sites is achgut.com. I recorded a network trace on the router. In this trace I see a lot of succeeding DNS queries from 192.168.178.109 (an iPhone). I see some other queries from 2003:ec:df10:1600:f419:5a6c:e4bc:f28e but I am not sure which device this is. The 192.168.178.109 is a MacBook. The router's ip address is 192.168.178.1.

I would like to know if the DNS query of failing iPad did actually reach the router. Unfortunately I do not know the ip address of the iPad. The iPad's hostname is "Abids-iPad".

My questions are: Is there a way to identify the device model in the trace? Does the trace indicate any DNS errors?
