Packet Loss in Qatar
jtmarcot:
For many years, I had my Obi110 running without issue in Australia. I've now relocated to Qatar, and I'm trying to get it working with the local fiber connection (Qtel), telco (Qtel), and GV.
After several attempts to re-configure my device with the Obitalk interface (settings would not push down), I ended up resetting and configuring, from scratch, through the device admin console. Given I'm not using VOIP, yet, this was fairly straightforward.
Calls are sent and received both thru the PSTN and GV. My issue, though, is that my GV call quality is horrific. Looking at a sample call status, my packet loss rate is at 50%. Direct pings to google look like this....
151 packets transmitted, 141 packets received, 6.6% packet loss
round-trip min/avg/max/stddev = 276.529/339.761/420.570/36.396 ms
It's fairly clear I'm dealing with line issues, but that's as far as I've made it. I'm running on just 1Mbps fiber, which could figure in, but then I'm guessing folks have success on less.
Are there any suggestions?
Shale:
Ping test to things locally. If you get this huge packet loss to everything local also, get your local system repaired. Let's hope the problem is in your house. If the packet loss locally is low, (more than 0.5% is not low) but it is high to Google Voice, look for a different VOIP provider.
jtmarcot:
Thanks, Shale, for the quick response.
Packets seem fine around the house. Here's the ping across wifi, thru my router, to my fiber box...
1243 packets transmitted, 1242 packets received, 0.1% packet loss
round-trip min/avg/max/stddev = 1.697/4.964/32.609/3.055 ms
I've tracerouted to the listed Peer IP address (Google) and everything's quite fast until I start hitting Google's network, where the ping timings go up to 400-500ms.
So, based on this, is the only suggestion to ditch GV?

I hope the OBi is not going through WiFi. Having 0.1% packet loss would be tolerable for VOIP, but I am not used to that kind of loss in the house.
Besides ping, jitter is important. You might try pingtest.net to look for jitter and packet loss to various servers.
I was suggesting you ping outside of your house. For example, look at the gateway listed in your router. This may correspond to the first address in a tracert (traceroute) that does not start with 192, 172 or 10. Let that get pinged for long periods, preferable from a computer that is wired to the router. If significant packet loss is detected, then the local communication supplier might be able to fix it. On the other hand, some routers do not return all pings.
500 ms ping time is a long time. That might be a problem, even if you don't lose packets. GV may indeed not be the best service for you if a faster connection is not available. A supplier with a point of presence that you can access faster could well be worth the extra cost.

OK, yep. Obi is across a gigabit ethernet - not wifi. That was just me misunderstanding your rfi.
Here's an ethernet run to the router listed on my fiber box (78.***.***.***)....
Packets: Sent = 500, Received = 499, Lost = 1 (0% loss)
Approximate round trip times in milli-seconds:
Minimum = 2ms, Maximum = 16ms, Average = 3ms
Regarding pingtest.net, I'm running into problems connecting to any of the test servers. I've tried 5 or 6 of them, each failing with a possible firewall issue. Could this be indicative?
