I exported the list to Excel and added the final column which shows the time elapsed between disconnects. There is a small cluster around 4 hours and very large cluster around 2 hours.

These disconnects are not random. There is a distinct pattern (with some randomity thrown in). They are regular, almost like clockwork! They began around midnight on 9 February and have continued ever since.

Before then I had been connected uninterrupted for almost 4 days.

I think mine are more random bcos of continuing signal fluctuations, I suppose if I did the same export to Excel I might notice a less-random trend in amongst the chaotic random trend.

**alchamy** · 17-02-2005 07:20 PM

I agree that these disconnections are not random, they seem to occur on the hour.

But it seems to be linked to the amount of time your connection has been active, rather than any specific time. If my connection drops, it redials in about 60 seconds. and then I guess there's the authentication process, which make it almost exacty 2 hours that my connection is allowed to be active before it is disconnected again.

My guess would be that something was installed on the network at midnight on 9 February but incorrectly configured. But that is just a guess...

ic · 17-02-2005 08:15 PM

Ok, now I am definitely going to export my filtered events to excel & figure this out, I suggest everyone else does the same - post results in this thread.

**Shaun Green** · 17-02-2005 08:45 PM

I have been informed that the disconnection issue has been resolved.

You should have maybe 2 disconnections tonight and that will be it.

Fingers Crossed. I have now been up for 2h32m.

I will get the full report on the cause of the problem tom.

Now we need the speed back.

I need more light in this tunnel.

Shaun Green

**Gatecrasher** · 17-02-2005 09:31 PM

Yes!

Interestingly, since I started this thread I have not been disconnected. I've been up and running now for 4h35m.

I'd like to think someone at Iburst read my post, clicked his fingers, cried "Eureka", fixed the problem, and told Shaun. But I guess it's all just a bizarre coincidence...

At least it seems to be fixed.

**AcidRaZor** · 17-02-2005 10:08 PM

Same, 4hrs 52min, amazing. However, Shaun is correct. We need the speed back. It is horribly slow.

And me being the work-o-holic I am, never really switches off his pc or NOT do research on the internet.

It's so slow its boring downloading porn even. Yes BORING

**slimothy** · 18-02-2005 01:02 AM

my speeds fine, just these disconnections, it was every 2 hours 1 minute, then the last day has been different, where it stays connected and I send data but don't recieve data and I have to power down and back on to reconnect properly. I thought it was fixed since I got 7 hours today, but alas about 7 minutes ago I had to do the power off/on thing.

Serves you right for stealing everyone else's bandwidth the past month...

**alchamy** · 18-02-2005 04:06 AM

Well I have 12hours of uptime

**Gatecrasher** · 18-02-2005 04:09 AM

Been connected 11h11m. Sent 16MB, Received 448MB.

Speed still good.

* Download time: 3.984 seconds
* Size of file: 500 KiloBytes
* Estimated line speed: 1024.1 (kilobits/second)
* Estimated line speed: 125.5 (kiloBytes/second)

Good night.

**alchamy** · 18-02-2005 05:01 AM

Yeah its all good this side 2, gonna get some sleep now

**zepher** · 18-02-2005 06:20 AM

Link uptime is 0d 9h 17m 15s and still going.

Nicely done.

Speed still sucks and pings to local IP's have lost packets and very high latency.

**Grimsqueaker** · 18-02-2005 07:23 AM

Disconnected at 12:30 this morning >

but it was going since about 6 yesterday - its an improvement, now lets see if it will keep going all day.
btw has anyone else had to reset the hardware before reconnecting?
