I have (at least) one problem with my wifi on my Lenovo E480 Notebook running Ubuntu 16.04 with a Realtek b822 wireless card. I can't really pin down what the real problem is.
I observed the listed problems below. Sometimes together, sometimes alone. After reconnecting to the network they are sometimes solved, sometimes not:
- Most of the time really slow connection (0.1 Mbit/s compared to 100 Mbit/s with Ethernet)
- Using
ping 8.8.8.8I found out that I get a lot of packet loss. Sometimes it says 'Destination host unreachable' but I am still connected to the wifi. - It's really unpredictable. It may work good for hours and suddenly decide to stop working. Or it works 5min before I need to reconnect again and again.
I'm mainly using my home network (WPA2) and the 'eduroam' network at university. The "Destination host unreachable"-problem seems to occur more in the university network. The wifi connection at home is always slow. (Just for the notebook, not for other devices.)
