The other evening, I suddenly could not connect to the internet (very well). I ran speedtest, and most categories were RED RED RED. The graphs looked horrible. I booted everything (M/OOMA/R/S) and everything sort of returned to normal. I have UPS power.

I have been noticing less than stellar quality of OOMA service. I already have to use *98 all the time. But I am now getting random instances of no connects. After running speed tests again, I have noticed degraded download performance, notably spiking of delays in the graph. My DL QoS is lower and jitter is much higher that it used to be, particularly on DL side. Nothing else was changed in terms of settings. Any clues?

EA PA:

Two things to try first:

If you Internet provider issues a dynamic IP address (not Static IP address) for your modem, try "cold" booting (restarting your modem with power full off. Some modems also contain batteries that won't allow a full cold boot until removed, so check that out too) your modem.

Each time your modem boots up, test with http://speedtest.phonepower.com/ to see if things changed. If there wasn't any improvement, do the modem reboot/test again, hopefully until you see improvement.

I'm in China right now, and I find I had to do the above step, to have the modem that I'm using, connect to a good Internet provider WAN router socket. The http://speedtest.phonepower.com/ tests have really come up with huge differnts in readings for me, after a modem reboot.

The getting random instances of no connects is probably an Ooma problem and you have to keep after them about that part of your problem.



Second:
Try setting your Ooma device's Ooma Setup Upstream and Downstream Quality of Service settings to double the measured Upload and Download readings as measured with http://www.speedtest.net/ and see what happens. Test with http://speedtest.phonepower.com/ again.

If these setting work, but there is problems with QoS for your other Network equipment, start reducing the Ooma device's Ooma Setup Upstream and Downstream Quality of Service settings until you reach a happy medium.

Guess I am not sure how often a dynamic address is (or is not) set.
I just now found a site that looks like I can check my current address. I plan to experiment to track when my address changes and if some are worse than others.
http://whatismyipaddress.com/

This is all a learning experience for me, but I think this is interesting.

Danlisman I tested and found your tool to very helpful. I also recorded to dynamic IP address that was not so good, and one that was better. The better connection is not only from a different router socket, but came from a differnt router used by the Internet provicer. The connection that I have now only has a very slight buzz, that I think I may elimate with a DSL filter on the phone line.

This information is probably common, but I did not know what I was looking at.
http://pingtest.net/
Pingtest has the same info in the lower left of screen. I thought it was their IP address instead of my IP address. After a few modem cold boots, I found an IP address that consistently gives me "grade A" ping tests. I have not used this site much, but I think I received "grade B" and sometimes "grade C" previously. Maybe I am overly optimistic, but I think this might be my new "gold standard" key for a test:
Reboot modem until my IP address consistently shows "grade A" on pingtest.net :)

I use this site also. Without making any changes, I get A, Ping 36, jitter 5 ms every time. I then recheck my graphs and still have lots of spurious increased in DL side.. UL not bad. Ill experiment with Thunderbirds ideas today and report back..

I wish it was as easy...This may be one explanation as to why the character of the whole loop seems to change with re-booting though! I hadn't thought of that before. This just may turn out to be the endless science project... :shock:

Google research says that my dynamic IP address is essentially static until a 5 day lease expires. I am not sure that means exactly what it says or says what it means. I will monitor my current "grade A" IP address to see if and when it changes. Then I will recheck http://www.pingtest.net to see if the new IP address is consistently labeled as "grade A". If not, I will cold boot modem until I find a new "grade A" IP address. Anyway, that is my current plan. :)

I checked the modem signal levels. They look good at:

DL SNR 38db
DL pwr +5 dbmV
UL pwr 44 dbmV

I did cold boot on modem.

My OOMA sits close to the WiFi router. Based on the forum chatter about OOMA RFI, just to be sure, I relocated it a few feet away.

My QoS UL was set close to measured UL speed @ 490 kbps. The QoS DL was disabled (modem/ooma/router). I increased UL QoS to 1000 kbps.

Tests run much better. On the ping test I dropped about 10 ms and on speedtest, the best one below. I'm not sure which one did it, but it is much better. The DL graph flattened a bit as well. Ill keep tinkering but I think this is case closed. Thanks :D

EA PA, have you ever brought your Ooma to your inlaws and plugged in to do some testing?
If theirs work great and yours doesn't, it must be your Ooma hardware.
On the other hand, if yours work great there too, then it must be your internet (line, modem, etc).
