London, ON milhouse6 Member [Cable] Mini-dropouts? (London) So at first I thought it was just me... have swapped out two routers, flashed multiple router firmwares, eliminated devices and switches. Over the last maybe 3 weeks or month I've been experiencing many 30 to 60 second outages. They're really nebulous, though. I just assumed it was my router rebooting or wifi issues. But device logs reveal nothing and I can't see any lights cycling to indicate reboots. Times of day seem random. Have tried switching DNS between TSI, Google and OpenDNS. Have tried bashing my head on the wall.



So now my referrals have started complaining at me... "why am I seeing 404s?" and "I think something's wrong with my network" and "sometimes it just stops working for a minute".



Interestingly, YouTube never fully drops out -- quality drops intermittently, but the stream rarely fully drops. I also see no interruptions on large file transfers once they initiate. It's weird.



Confirmed with 4 London TSI customers scattered throughout town with a variety of routers, and I've personally verified that are signals are well within spec (35-50 and -10 to +10) on DCM 475/476s. Any known issues? Any recommended tools we could be running to help with reporting?

London, ON graniterock Premium Member I have got the odd not found that a reload fixes. My wife mentioned the other day occasionally it feels like her ipad has lost its connection for 30 seconds or so. I just assumed my router was being quirky.



Like you it only seems to be for new connections. Not existing connections.

London, ON milhouse6 Member Exactly. Thanks for chiming in!



To clarify, I agree -- it doesn't drop existing connections i.e. current transfers, voip calls, whatever. But even a page refresh initiated during one of those mini-outages won't go through.

I haven't had the problem the last little bit but it is in recent memory. I actually wonder if it had to do with what was explained on the front page last week » If it pops up I'll let you guys know. Although it may be hard to troubleshoot because speed and ping tests just after are fine and hitting reload 2 or 3 times fixes the problem.I haven't had the problem the last little bit but it is in recent memory.

Although I would have expected to see more people squawking if that were the case.

Ottawa ON Datalink Premium Member I would say in both cases above, look at your power levels, which should be at or near 0 dBmV for receive, and in the range of 37 to 40 dBmV on the transmit side. If you are at an extreme level, ie +/- 10 dBmV or more, then your in a region that makes your signal level susceptible to minor fluctuations that occur, to the point where you loose the receive signal, and probably loose the upstream path back to the node. Operating within the range is okay, but you want to be comfortably within the range, not out at the extremes on a constant basis.
