Currently, I installed Lubuntu 20.04 on my Thinkpad Lenovo laptop. sometimes the networks became very slow, I command a ping 1.1.1.1 or ping 4.2.2.4 but it falls in a very deep delay. parallelly, I connect to my modem by my Android phone and the result of ping is so good, something around 100 till 170 ms, this is my last ping:

When I turn off and then turn on the WiFi, it became ok but after few seconds it falls into trouble again and I don't know why. sometimes like now, I don't have any problems. but sometimes it became very laggy and slow.
