Which anti-virus was on the laptop ?
In the case of our customer's Dell, AVG Business...
Sorry scratch that, I was telling porkies!
Went back to the customer's site yesterday to spend some time working out what was actually going on. (previously we had to revert to the previous hardware to get the client working again since they had deadlines to meet). Anyway, did some wireshark captures to look for patterns and found a few interesting things...
Firstly setting the machine to static IP did fix it for wired and wireless, as expected.
However running dynamic IP did not actually automatically cause the crash every time unless the 2830 also had internet connectivity at the same time. We could get it to run successfully, when just plugged into the 2830 in isolation.
With the 2830 online and connected, the crash did not seem to happen until a short time after the DHCP request and response had actually finished. (not waded through the logs yet to see exactly when or if there was a common event after). Tried knocking off the Win 7 IPV6 stack and any other non essential networking components and that made no difference. Updated network drivers and all that. Still no difference.
Then the revelation - my colleague mentioned that the copy of
Kaspersky internet security was about to expire on the laptop! Which was when I realised that this machine was
not running AVG after all. (normally we configure each new machine with the customers standard software stack when it goes in, but this machine came in via a different route and hence did not get their site licensed copy of AVG on it).
Remembering your comments about similar problems with Kaspersky, we had that away, lobbed on AVG Business, and problem fixed - no more crash.
So while the problem seems to be related to something the 2830 does differently from some other routers, it was not actually its "fault" - the blame seems to rest with Kaspersky internet security 2011 in this case.
HTH
