Wifi not working after hibernate

Asked by Jan

Since the beginning Ubuntu is working very bad with my RTL8723 Wifi Chip. Bluetooth never worked correctly and Wifi always was much slower than under windows, but what is the major problem: after waking up from Hibernate, the Wifi is not able to connect to networks anymore, which is - in case of a notebook - making the system rather useless :-)

I tried some experimental drivers from GitHub (rtlwifi_new) but they discontinued Ubuntu Support because of Ubuntu changing the linux kernel(??). (Realtek support also told me to try those drivers)

Any ideas how to make this running?
