WiFi problem on RasPi 3B

Postby PerLinden » 09 Jul 2018, 10:49

I have been using my RuneAudio on RaspBerryPi 3B
and Ver. 0.4b build 20170229 (the inofficial one with
an Access Point) for say 4 months with no big problems.
Using WiFi.
There are typically 6 -7 users on the network, mainly cellphones.
It seems the system has degraded.
I normally get the RuneAudio GUI on my cellphone (Samsung S7)
or laptop following Power On.
After a few minutes, I loose the contact with Rune.
Sometimes I can "toggle" between the 3 main menues (Library, Play and
Playlist). In Play, I get the "rotating circle".
I can also see (using for example Advanced IP Scanner) that the
original IP adress has disappeared or is shown as "inactive".
It seems there are no problems with WiFi on the laptop
or the cellphones, so the router WiFi is probably working correctly.
The distance between the router and the Pi is just one meter,
with virtually no obstacles in between.

Could it be the Pi WiFi Hw has degraded ?
I want to avoid cables.
Any suggestions ?

Hi PerLinden,
Seems strange considering the distance between PI and modem. Unlikely that the Pi hardware has problems.
The built-in Wi-Fi on all the PI models is poor, but this should not be an issue at these distances.
Could you start the debug screen from the menu, look for something like this:
Code: Select all
wlan0     IEEE 802.11  Mode:Master  Tx-Power=31 dBm
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Power Management:off

Could you check for the text ‘Power Management:off’.

Hi PerLinden,

Could you start the debug screen from the menu, look for something like this:

Or better post the complete debug info.

I did some "research".
Moved the Pi to a more open place, 1.5 m from the router.
It seems that the WiFi got disturbed by some items that the maid
had put on the shelf where the RasP was located ! :lol:
Should have checked that first !

Now it works flawlessly like before, and I know
there is nothing wrong with my hardware.
The Debug Info has the text you requested, so I do not send it.

Thanks for helping and Thanks for developing RuneAudio,
an excellent player !

Best regards
PerLinden

Hi PerLinden,

great to hear that it was not an issue with your hardware or Rune.
