Hello guys, quick q;

 

Since Friday evening, our internet has been spotty.  Off for a bit, blazing fast for a minute, off, slows to a crawl.  This is most out of character for our ISP.  I've also noted some oddities with our router (not letting a machine connect to the network unless it's restarted, taking an age to reset sometimes) so that complicates the question.

 

Basically, regardless of the DNS set in the router, we're getting about 20-30% packet loss.  I've tested this several times by pinging both the ISP DNS and Google DNS (I've tested when using the default ISP DNS and Google DNS too).  Always 20-30% per ping test (pinging 20 times per test).

 

If I ping within the wireless network, 0% packet loss consistently.

 

So that would mean that there's an issue with the ISP, correct? Sadly, they're not open on weekends (small ISP in Switzerland) so I haven't been able to call, but if it's our router then I'd like to go buy a new one tomorrow otherwise I won't have chance again for a few weeks, and putting up with crappy internet won't make my job any easier!

 

Thanks for your attention.

If you are recieving packet loss when pinging from a computer that is wired directly to your router but no loss from a computer connected wirelessly to that same router, you probably have a bad cable between the computer receiving the packet loss and the router.

No, nothing is wired directly to the router, it's not in a useful place to do that without drilling - which is pointless because up until yesterday the connection has been rock solid.

 

Basically, pinging within the wireless network = 0% packet loss, pinging outside of it = 20-30% packet loss.

I understand now.  So it's not a problem with your internal network.  It does sound like it is an outside problem, whether your ISP or the servers that you are trying to ping.
