I made a ppa with new Realtek wireless drivers. They fix most of issues.
Theu can be installed by
sudo add-apt-repository ppa:hanipouspilot/rtlwifi
sudo apt-get update
sudo apt-get install rtlwifi-new-dkms linux-firmware
Note: For some usb dongles this combined driver does not work well.

The problem has been reported to the linux-wireless mailing list. If anyone is

Paweł Kowalik, just to clarify, are you connecting via 802.11n, 802.11g,

Paweł Kowalik, it would help to know if using 802.11g has better
performance than 802.11n 150.

Title:
Realtek RTL8723BE drops
Alright, after switching to 802.11g (54Mb/s) I've noticed a small
performance improvement while browsing websites. However there are still
