sporadic network drop - 2830n was created by cookan
Hi,
can anyone tell me how to get the routers uptime as opposed to the WAN uptime ? I'm getting periodic network drops and throught it was just a homeplug losing it but noticing my wireless devices are losing their connections also. Checked with my broadband provider and they said I'd dropped off 3 times in the last 3 hours so wanted to check whether it was the router rebooting itself, or just the broadband dropping.

I do see this below...

note...I received an OTA update for my HTC One X (not +) yesterday taking it up to Jellybean (Android 4.1.1) though I've been noticing my desktop disconnecting for a while now..prior to this update...it just seems more frequent since yesterdays update.

If someone can tell me how to monitor the routers uptime, I'll log it for a while with HOX connected..and discconnected to see if it correlates.

thanks,
Ant.

Hi,

I have also had my HTC oneX upgraded to jellybean, and it has caused two draytek routers to start rebooting themesleves!

I have a 2850 at both home and work. The work one has a older firmware version, the one at home the very latest, and it happens on both. No reconfiguration or change has been done on either router for months, so that's not the issue.

Others are also having the issue;
