Superhub bouncing

foxtrot_yankee · 22-02-2011, 23:22

At least once a day, my Superhub will drop connection and I can't see why. The power levels are slightly higher than expected (+9dB) but shouldn't be causing much trouble really. SNR levels are good (+44dB). The event log shows:

And here are the levels:

Any ideas?

Just as I hit Submit there, it dropped again.

Sorry, I'm no help, but I had to say your subject line made me smile. With the frustration that some people are having I pictured it 'bouncing all the way down the drive after being flung out the window LOL

I'm sure someone will be along soon who may have something more constructive to say.

Have you turned off the firewall and ip flood?

6db attenuator would sort that out. call up and book a techie

If this is the case then that's really annoying. The engineer took my attenuator away when he came to install the 50meg. He connected the coax to his piece of kit and said the signal was "perfect" and chucked the attenuator in his holdall.

probably needed one to take home lol

Called today and an engineer is booked for tomorrow morning. Turns out the superhub has adjusted itself 267 times in the last 3 days.

That's nothing. W-CDMA phones adjust themselves 1500 times a second.

It won't necessarily sort the issue that the OP has.

A 6db attenuator will not sort it out, expect a modem swap and the same issues on the new hub

Why same issues on the super hub?

Some info on said T3 error's, and how the modem works:

Because techs have no tools to detect what is causing t3 timeouts or why it occurs, they also can't pass it to networks as the tech can't prove it's a network issue

Trouble is, as you might know, various departments jump on the fact that it IS an upstream network issue and immediately blame the local area network but as you state there is no immediate way of knowing where or how it is occurring so very difficult to diagnose.

whoa hang on there. everything else is fine, just the high downstream power levels! as iv already said, a 6db forward path attenuator should do the trick!

jb66 · 23-02-2011, 21:38

Really? because if I take my attenuator off my superhub it makes NO difference at all!

It will attenuate the Downstream levels your right in that respect, but it won't sort out the problem the OP is having
