I'm suddenly having wifi connection problems with many Puppies on a Samsung laptop. It has built-in wifi (=wlan0).
Windows7 has had no problem connecting (came with the laptop).
Using wlan0 had been fine for all Pups (32 & 64 bit) for years, but for the last week or so, I'm seeing erratic behaviour.
For many but not all Pups, I cannot "find" the SSID of my router when scanning with any of the Puppy wizards. Neighbours' weaker SSIDs show up but not mine, even if I'm next the modem-router (Telstra Smart with nbn)
I've tried a USB dongle (=wlan1) which sometimes works (finds the router on a scan and connects).
Running "ifconfig -a" lists a strange device 'tunl0' with a stranger Mac address, this is with and without the good USB dongle (wlan1) plugged in (screenshots).
There are errors in wlan0 packets - are these related to tunl0?
Can I remove this tunl0 as it seems, so far, the only thing to explain this sudden inability in my laptop to connect Puppies by wifi to my modem-router? If so, how?
I did not see any 'blacklist' on the router when I logged onto it.
All very strange and too technical for me

Thanks for any help.
