In any case the five Tiny-TV Pis (which are all further from the Antenna) would also be affected. The site is in a fairly sparsely populated area with a field and cricket ground behind, a few houses either side and the Minster across the road. > Could you setup a simple ping script to a router or something similar > and i it fails to get a reply then it reboot the PI? I'm looking into doing something like that at the moment. The latest suggestion is to turn off WiFI and then turn it back on again, if the ping response fails. I need to be careful; if the script has an error, I may never get the WiFi back up. That would need someone on site to fix it. -- Terry Coles -- Next meeting: Online, Jitsi, Tuesday, 2021-08-03 20:00 Check to whom you are replying Meetings, mailing list, IRC, ... http://dorset.lug.org.uk New thread, don't hijack: mailto:dorset@mailman.lug.org.uk

Has a new Wifi to the area appeared and is swamping music and bells wifi, thus forcing it off line? Could you setup a simple ping script to a router or something similar and i it fails to get a reply then it reboot the PI? Does not solve the issue but keep it running Tim H On 01/08/2021 09:33, Terry Coles wrote: On Sunday, 1 August 2021 08:12:03 BST Terry Coles wrote: This system will of course reboot in an hours time.

[Dorset] WiFi Still Dropping Out at WMT - Yet Again
Hi, This has been discussed ad infinitum on this list and also on the WMT Forum. To recap; the WiFi connected to the Music Pi drops out after 2 to 3 days of operation and the output of iwconfig shows that the number against Invalid misc: increases steadily. The only way to regain WiFi access has been to get the on-site manager to power cycle the complete system, whereupon I would get another 2 to 3 days of access. The Music and Bells continue normally. The Raspberry Pi Zero Ws installed in a number of locations on this site do not have this problem. After trying many suggestions I setup a function in the Music software to reboot the Music Pi at 0900 every day. I also made sure that an entry was written to the Music Pi log file when it happened. Everything has been fine and the log entries have been as expected, until today when the WiFi dropped out again So what's the difference between a reboot and a power cycle WRT the WiFi adaptor? Could the WiFi Access Point be playing a part in this? (I turned off Power Management, as suggested on this list, after one of the suggestions from this list.) This system will of course reboot in an hours time. If that restores connectivity, we can probably live with the situation, but I'd really like to know what is going on. -- Terry Coles -- Next meeting: Online, Jitsi, Tuesday, 2021-08-03 20:00 Check to whom you are replying Meetings, mailing list, IRC, ... http://dorset.lug.org.uk New thread, don't hijack: mailto:dorset@mailman.lug.org.uk
