#2

Does anyone know why Hikey 970 WiFi can be connected but prompts that there is no Internet?

#3

Are you able to get a valid IP address (if DHCP in use)?
If yes, check the routing and firewall configuration.

When I tested the builtin WiFi using a custom compiled Linux kernel, I didn’t spot any problems.

#4

I found it on my own compiled Android system.
I can get the IP address.
Does Android have a firewall?

#5

I don’t see wi-fi MAC address, could this cause this problem?

#6

Networking under Linux and Wifi has generally two ways to setup.
Either you are using manual setup with the commandline tooling or you use a desktop setting.

For each of those there is a huge amount of info to be found on the internet.
These issues are generic Linux and distibution related. Not specific hikey970.
Do you have extensive Linux experience?

#7

I surf the Internet in China, but China cannot directly access Google. According to my data, after wifi connection, a Google page 204 will be automatically visited to determine whether this hotspot is connected to the Internet.I think that’s causing my problem.:disappointed:

#8

Maybe you could try to change the test server address: wi fi - Is it possible to designate an alternative wifi connection test site? - Android Enthusiasts Stack Exchange

#9

In china, you can’t connect www.google.com/generate_204.so , you can use http://connect.rom.miui.com/generate_204 to replace www.google.com/generate_204 in /frameworks/base/services/core/java/com/android/server/connectivity/NetworkMonitor.java
