https://community.arlo.com/t5/Arlo/Cannot-re-sync-after-removing-devise-and-changing-batteries/m-p/1622219#M55249 I just bought a new camera a week ago. I had trouble synching too. It finally worked but i had to keep pushing the button. I think i pushed it quickly not holding for 2 seconds as the manual say and it worked Sat, 11 Aug 2018 19:24:30 GMT Wklovelace3 2018-08-11T19:24:30Z https://community.arlo.com/t5/Arlo/Cannot-re-sync-after-removing-devise-and-changing-batteries/m-p/1622157#M55247 <P>Reveived an error that firmware needs updating. Attempted multiple times to do manual update with no luck. Then error that batteries low. Replaced batteries and still&nbsp;unable to re-sync. I then removed camera and attempted to re-sync again. <SPAN>The light on camera does blink blue during syncing process but never connects</SPAN>. Any help would be appreciated. Note: My second camera works fine. Thanks everyone.......</P> Sat, 11 Aug 2018 17:19:56 GMT https://community.arlo.com/t5/Arlo/Cannot-re-sync-after-removing-devise-and-changing-batteries/m-p/1622157#M55247 Dugey123 2018-08-11T17:19:56Z https://community.arlo.com/t5/Arlo/Cannot-re-sync-after-removing-devise-and-changing-batteries/m-p/1622219#M55249 I just bought a new camera a week ago.

I use less than one second and it works fine.</P> Sat, 11 Aug 2018 20:09:21 GMT https://community.arlo.com/t5/Arlo/Cannot-re-sync-after-removing-devise-and-changing-batteries/m-p/1622238#M55250 jguerdat 2018-08-11T20:09:21Z
