Hi all,

Whenever one of our part-time staff members visits the office and fires up his Mac, our Vigor 2850N reboots. It's like clockwork... if he's not here for weeks then the router is rock solid, but as soon as he arrives it reboots. We've raised a support ticket, upgraded to v3.6.4, and have followed support's advice to switch on IGMP snooping, but all to no avail.

The Mac appears to be running some Sonos app (which I believe uses broadcast or multicast traffic to find peers), Spotify and Box. I _suspect_ the Sonos traffic is the cause, but it's difficult to pin down as this user is so infrequently in the office.

Does anyone have any suggestions? I've tried searching for "reboot" here, but apparently that term is too common!

I see there's a 3.6.6 firmware posted now, which I will certainly try, but I'm not optimistic as none of the fixed issues really match my description.

Thanks,

Sam

Is he sitting down where the router is...maybe he's unplugging the router to use his Mac )

Seriously though, if the router is rebooting, there is a telnet command (which I've forgotten this minute)
that may give the support engineers clues, so raise a ticket.... or just tell him he's not welcome

apart the ticket support maybe a quick guide to block ... is via bind ip to mac

Try to get his mac / ip next time the vigor should detect his/her device

Thanks both.

Admin - Support haven't suggested any telnet commands. We've tried capturing the output via syslog'ing to a remote server, but nothing is recorded when the reboot occurs. And no, the user in question sits well away from the router!

babis3g - I may end up having to do that, but I'd really rather not. After all, it's not the user's fault, there's clearly a problem with the Draytek here, so I'd like to resolve it properly. This was an expensive router after all (compared to our old Technicolor anyway, which didn't suffer from this problem (but had many others of course...))

Thanks,

Sam

ah sorry i though possibly was doing something to your network

I guess if you already in touch with the support team, they know better but have you tried the new firmware 3.6.6 ??
is the one you having the problem?
ftp://ftp.draytek.com/Vigor2850/Firmware/v3.6.6/
If you need to update you may need to use the *RST* to clean everything (so possible previews bugs) and all settings back from the begin

Not yet, 3.6.6 is next on my list of things to try. I'm giving support another chance to come up with something, but they take a couple of days to reply to each email frustratingly.
