WIFI sleeping?

[phillx19090]

Hi,

Raspi 1 B+
IQAudiO Pi DAC pro
rAudio 20210827

Of necessity I have to use a wifi dongle between laptop -->>router-->>pi. All is well apart from a slight annoyance as the pi goes incommunicado after about an hour. Ping times out but the pi is clearly still alive as it will happily play all day.

Nothing on the router to shut it down, all wifi light switches work etc.

ifconfig wlan0

iwconfig wlan0

wlan0: flags=4163 mtu 1500
inet 192.168.1.120 netmask 255.255.255.0 broadcast 192.168.1.255
ether e8:4e:06:57:39:1c txqueuelen 1000 (Ethernet)

wlan0 IEEE 802.11 ESSID:"ONTITEL_080819"
Mode:Managed Frequency:2.412 GHz Access Point: 00:E0:4C:AB:28:E8
Bit Rate=150 Mb/s Tx-Power=20 dBm
Retry short limit:7 RTS thr=2347 B Fragment thr:off
Power Management:off
Link Quality=40/70 Signal level=-70 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:27 Missed beacon:0

Any nudge in the right direction greatly appreciated.

Appologies. To be clear, the dongle is on the raspi.

I have no experience of using the B+ but that iwconfig output looks odd, as it includes ethernet information but does not show the dongle name.
The signal level is good and power management off, so I would try disabling anything which might try to grab wlan0. In the settings, click on the cog next to wifi on/off, and disable the AP option. I know there is no onboard wifi, but it might also be worth adding dtoverlay=disable-wifi to /boot/config.txt, in case the OS is trying to use something which does not exist.

I assume you have other DHCP devices which stay connected, so there is no chance the router's DHCP lease time is playing up?

Many thanks for the reply and for not saying, "Your very old B+" ;-)

I´`ve added the overlay and will leave it a while. All other wifi switched etc continue to work without problem so I think the router set up is ok. If the config change doesn´t work then it might be the wifi dongle itself. As long as I make some input to the web server the connection stays alive. Way past time to update the pi I think.

Again, many thanks.

If it continues to fail, it would be useful to run it with an ethernet connection as well as wifi. Then you can easily check what state it is in after it fails.

[phillx19090]

A good idea. I´ll try that if it fails. Currently it´s gone 2 hours and still accessible, which is an hour longer than previously. If I can still access it when I go to bed then I´d call that a result.

Thanks

Thanks R101, dtoverlay=disable-wifi has done the trick.

Glad to hear that, but I have no idea why :)
