Have tried using both the Home Parrot 4.11.2 XFCE amd64 & Security Parrot 4.11.2 amd 64 ISOs to make a live USB with etcher & antiX Live USB maker, & dd command from the terminal (for a total of six attempts). I have also tried each of those attempts on two different laptops, HP NoteBook with an Intel 7260 wireless wireless, & a HP EliteBook with a Centrino Advanced-N 6205 wireless interface. In all cases I was unable to connect to the internet, though the icon in the system tray seemed to show I was connected.
The installed OS on each laptop was antiX 19.4 with 5.10 Kernel, both of these have no problem connecting to the internet. I also verified with three other live USBs, with Kodachi, Predator, & antix 19.4 installed on them, all three of which could also connect to the internet.
Also, I temporarily had Parrot Home made from the same Iso that I made the live USB from, installed on my HP Notebook & had no problem connecting to wifi.
ParrotOS iso in use:
Application used for flashing the iso:
Etcher, antiX Live USB maker, dd command from the terminal
Logs/Terminal output (use pastebin or similar services):
I only made the first USB persistent, but once I noticed the problem, I wrote over the USB in to try again. All the following USBs were made without persistence, as I was focusing on the problem connecting to wifi. So there are no logs.
Same answer as above for logs/terminal outputs.
