Another strange 2700 **^&*$^ feature

[Odos]

I've had my 2700 for just over 4 weeks now. It's one of the new ones ( march 09 manufacture ) and came with the original V6 firmware. All was well for the first 10 days then it upgraded to the latest firmware which caused a resync.

Nothing strange there but then it gets wierd. Because of past problems my SNR target is set at 15db and I sync at around the 2500 mark. As with most people my noise margin increases by about 3db between night and morning. So after the firmware upgrade I was checking the SNR and noticed it was reading 18db. As the router had not been power cycled since updating I decided to power down the 2700 then restart it a minute later.

Strangely my SNR had now dropped to 12db and my sync was around 1800. I then did a software resync and it went up to 15db with a 2400 connection. I've done a few tests since ( spread out over time ) and it seems that if I do a power cycle reset then my connection goes all screwy, but if I do a software resync it behaves as you'd expect.

Has anyone else come across this or have I got some extra "features" on my 2700

I'm only guessing, but would it be to do with one only disconnecting you from IDNet, and the other, from the whole network?

I don't "know" but always assumed that a software resync did the same as a powercycle as far as the actual connection goes. Both disconnect from the exchange then negotiate a new connection and speed. I thought the only difference was that a powercycle reboots the router causing a firmware reload and re-initialisation. If this is correct then it must be something in the latest firmware or my particular router that sends it screwy

As I said, I was only guessing.  I expect someone will explain later.

It sounds like the software re-sync you talk of is just a PPP reconnection. If it is, then sync is not affected. Otherwise, I can't think why you should experience such a clear trend between a cold and warm restart.

Odd, the only thing I can think of is a router fault.

That was the conclusion I came to Rik. Possibly a bad firmware update 

Seb : It's a true resync not just a dropped session. My sync speed and profile took a hammering each time I did a powercycle, but recovered ( in due time ) after a software resync.

Oh well just another one of those cyberspace anomalies
