I have Ubuntu 16.04LTS (dual boot with Win 10 ) installed on my Laptop. Initially there was no wifi driver pre-installed(Although Wired connection was there but no wireless). So I installed Realtek "rtl8723de" wifi driver from git repository[Repository Name: rtlwifi_new ] (according to the wifi card which is there on my laptop, I checked this through Device Manger in Windows). Now wifi is working fine. I can connect to my mobile hotspot's network or my friends hotspot network. But I can't connect to HP network ( my hostel's wifi network, open network). Also this HP network works fine in windows. I mean I can easily connect to HP when using windows. So what should I do ???
I have tried restarting the network manager by giving command
sudo service network-manager restart
Also after executing the command
sudo modprobe rtl8723de
No error is flagged. Here's the output of the command
sudo lshw -class network
Output:
