I try to establish a wifi connection with my router, however, it does not work, no matter what I try.
lo no wireless extensions.
wlan0 IEEE 802.11 ESSID:"A1A0".
Mode:Managed Access Point: Not-Associated Tx-Power=20 dBm
Retry short limit:7 RTS thr=2347 B Fragment thr:off Power Management:off enp7s0 no wireless extensions.
I also tried to restart the network manager with
sudo service network-manager stop and then
sudo service network-manager start. It did not help either.
I also stopped the network manager and tried:
sudo iwconfig wlan0 essid $SSIDand
sudo dhclient -v wlan0. It did not work that way.
lshw -C network gives:
Beschreibung: Kabellose Verbindung
Produkt: RTL8723BE PCIe Wireless Network Adapter
Hersteller: Realtek Semiconductor Co., Ltd.
Konfiguration: broadcast=yes driver=rtl8723be driverversion=4.10.0-42-generic firmware=N/A latency=0 link=no multicast=yes wireless=IEEE 802.11, so the driver is from Realtek (rtl8723be).
I also tried
sudo apt-get install --reinstall bcmwl-kernel-source. No success.
Has anybody an idea, what I can try to wireless connect to my router?
Thank you in advance!!
