Is it possible to work 2x adapters at the same time Wifi Raspberry PI 3 B Raspbian?
Good day!
Available:
Raspberry PI 3 B+
OS: Rasbian
wlan0 - a module built into the board, launched an access point on it to control RPI wirelessly. Everything works well and I'm happy.
wlan1 - TP-Link adapter that I connect to USB and through it I try to connect to the network to access the Internet.
Not to confuse you - I'm not trying to connect to Raspbury and get the Internet through an access point.
I'm sitting at the very raspberry with the Internet connected and I want to surf (but the access point must always be active wlan0 )
The problem is this:
When the access point is active, Internet access does not work.
That is, you can see that the TP-Link wlan1 adapterconnected to the router, passed authorization, received an IP but no Internet.
As soon as I turn off the hostapd sudo systemctl stop hostapd
service - I go to the browser everything works fine.
What I did:
After installing the OS, I configured only wlan0
wlan1 did not touch - I decided myself, I decided not to spoil it).
