Excessive bandwidth after connect base station, no cameras

[K2Fruits]

Reconnected base station after 6 months of not using system. Did not have any cameras active (all with batteries removed).  According to ATT report, system uploaded or downloaded 17GB of data over 2 hour period and then went to zero.  Any explanation for this bandwidth usage?

K2Fruits,

While the base station may have updated firmware, without cameras there shouldn't be much activity beyond that. It sounds like something else on your network was using the bandwidth rather than the Arlo base station.

Thank you for the reply.  Funny thing is that the only other thing connected to network was my laptop and it’s usage was broken out separately from Arlo.  Laptop wasn’t doing anything so not sure what happened.
