[SOLVED][RPi 2][WIFI] Connected but no internet

[raysko]

Hello,

I connected a wifi dongle to my RPi 2 and it is connected to my internet box but it says “no internet” and I can’t ping google.com or even the gateway.
However, when I am connected to my phone (as hotspot), it is connected to the internet.
I have tested several modifications (of configuration and I modified the box wifi to wifi b/g/n to b/g) and I have tried to go as close to the box as possible, and I have no clue of what’s going on.
If anyone has any idea…
PS: I don’t know what log I can provide, but tell me and I will gladly provide.

Thanks,

Raysko

Seems to be connecting then dropping out, you could try connecting via the commandline:

Could not connect to Wi-Fi

@Marky @oliver1 Can you both try connecting to wireless using the command line tool connmanctl. This will rule out (or implicate) the networking GUI. To do so you’ll either need to temporarily connect Ethernet and run the command via an SSH session, or plug in a Keyboard and exit Kodi to log in at a local console session: Once you’re logged into a command prompt the following demonstrates enabling wifi, scanning for networks and connecting to an authenticated network: osmc@rpi2:~$ connman…

Thanks Tom.

So, after investigating, I can connect to my home router and on the internet when the connection does not have encryption (no password protection).
I don’t know why, but some guy says it may be related to a wpa_supplicant issue.

HI

@raysko

I can connect to my home router and on the internet when the connection does not have encryption (no password protection).

This would suggest your router is using tkip rather than aes, tkip is insecure:

If for some reason you're still using TKIP crypto on your Wi-Fi, ditch it –...

I assuming your router is provider by your ISP, I would see if there is a a firmware update.

Thanks Tom.

Thank you for the tip!
I switched to AES encryption (by default it was on TKIP/AES, that is why…)
Again, a BIG thank you!!
