Dear readers,
I have problems to get my hostapd up and running with an external wifi adapter as described below.
Any help to solve the problem is more then welcome.
With many thanks in advance,
wimduk
The problem
- I installed and configured hostapd on my Raspberry 3B+ and every thing worked as aspected.
- The wifi range was not suitable for me, so I connected a long range wifi adapter Alfa AWUS036NHR, chipset RTL8188RU
- Updated hostapd.conf : interface=wlan0 → interface=wlan1 → rebooted the system
- hostapd does not work properly
4.1 selecting wifi network and password : → OK
4.2 the obtaining IP process : → remain in a loop. - systemctl status hostapd gives wlan1: interface state UNINITIALIZED->COUNTRY_UPDATE (see below)

Remarks wlan1
1. In the wlan1 entry does not contain a IP address, but inet6 fe80::2c0:caff:fe6b:1d0b/64 scope link
2. If I connect to the hotspot the message “obtain IP address” continuously.
