Hi Seeley,
It’s probably a sign that the WiFi dongle is packing in, either because it has developed a fault itself, or it may be getting affected by one of the other nearby components (e.g. the 1090 SDR dongle) overheating.
Can you see the WiFi Hotspot at all? If so, please take a screenshot of the PAW Home Screen (via 192.168.1.1) and post it here so we can see what is going on.
Fix Options are:-
1. Try a replacement WiFi dongle.
2. Check and replace the 1090MHz SDR if faulty.
3. Upgrade your Classic to a Raspberry Pi 3 Motherboard (which has onboard WiFi), but you will also still need to replace the SDR if it is faulty.
4. Upgrade to a new Rosetta and enjoy the benefits of Pi3 with onboard WiFi and Bluetooth Audio, faster processing and a more reliable ‘low-power’ SDR. (There is a ‘trade-in’ upgrade option, where the core of your old Classic will be refurbished and donated to help set up another new OGN-R station).
Hope this helps
Regards
Peter
