What is the output of this command?
It may be preferring usb0 and if that doesn't have internet access, that will cause issues.

Here is the output :
| Code: |
default via 172.16.42.2 dev usb0 metric 4
default via 192.168.1.1 dev wlan0 proto dhcp src 192.168.1.27 metric 600
172.16.42.0/24 dev usb0 proto kernel scope link src 172.16.42.1
192.168.1.0/24 dev wlan0 proto kernel scope link src 192.168.1.27 metric 600

usb0 is connected to an other pc . That pc has access to internet on its own network . That pc does work but not this.

It is trying to use the usb0 connection as a default route. This could work if that system is configured to forward traffic.
It's probably easiest to remove that default route, and tell dhcp to not get a gateway for that interface, unless you'd like to use it for internet access.
You could also adjust the metric, but it doesn't help to have something listed as a default route when it's not functioning as one.
You can remove that route manually with:
| Code: |
ip r del default via 172.16.42.2 dev usb0
|
But know that it will likely return next time it gets a lease if dhcp is used.
