Is there any way to check if actually my embedded device has a working connection (i.e. can reach the WAN)? My device has no RTOS, so I cannot rely on OS functionalities like ping. I can see that the DHCP gives a correct IP to my device, but it's not 100% true that given a correct IP I can then reach for example www.google.com.
I've already done some research, and there are different approaches:
- it's impossible
- it's a stupid question
- workarounds of every sort, but I feel confident with respect to SO so I'll give it a try.
So, if this is question has 1) or 2) as replies, I'll remove it and it's ok.
