Saya telah menginstal Ubuntu 15.04 di laptop saya dengan kartu Wi-fi RTL8723BE. Tetapi selalu memutuskan koneksi dari jaringan. Saya sudah mencoba echo "options rtl8723be fwlps=N ips=N" | sudo tee /etc/modprobe.d/rtl8723be.conf
tetapi itu tidak membantu. Apa yang bisa saya lakukan untuk mencegah wifi terputus? Jika saya meningkatkan ke kernel 4.X, apakah ini akan membantu?
