Here's a possibly very stupid question. We're having some minor problems with our connection. At least, that's the face of it. The connection is rather slow (it's only 30Mbit symmetric, which is quite bad), so there's a chance it's the connection itself. But I want to make sure if this problem is indeed the connection quality (i.e. ISP drops packets) or the connection speed (i.e. too many people are trying to do things and packets get dropped) or, possibly, invalid configuration / low UTM resources (UTM can't handle requests).
All I know is that if I try to ping, say, 8.8.8.8 from our network, occasionally packets won't go through. Likewise, if I ping 8.8.8.8 after connecting to the UTM via SLL, some packets will not go through. Finally, if I ping one of our public DNS names from outside, some packets will get lost.
What can I do from this point to try and identify the reason behind the dropped packets? I don't want to call our ISP without evidence the problem is on their end, for example... especially if it turns out that it's just us saturating the small bandwidth we have!
PS. At the moment there's no QOS. I wonder if, given the low bandwidth, if this is even a sensible thing to add...
