I've just install elementary Odin on my laptop for the second time. Each time everythings is working well, internet (wifi and ethernet) is working smoothly. But for the second time 24-48h hours after elementary install, I have no more internet :
- Wifi is activate and connected
- Ethernet works
- but not internet connection when I ping google.com or try to open Firefox, neither when I tried upgrade or update.
I didn't change any network configuration this elementary install. I've tried several possibilities : restart network manager (don't work), re-install elementary (works for some times), and I don't see how to diagnosis this problem. I've checked network manager, hardware configuration and material. Can somebody help me to diagnos and correct my problem ?
