Again I dont know if its just my camera that has these issues.
I have tried other methods of connection, but the motion issues listed above remain the same with all connection methods.
Examples.
From TG862G wifi to 2530 (settings at default and IPv6 enabled, it will connect only once).
From TG862G wifi to 2530 (IPv6 diabled, IPv4 connection works but disconnects sometimes, sometimes wont stream).
From TG862G wired to cisco linksys wrt54g wifi to 2530 (IPv4 or IPv6 will connect locally, does not see cloud or external remote connection).
From TG862G wired to DD-WRT linksys wifi to 2530 (Will connect to IPv6 but wont stream, IPv4 disconnects frequently).
From TG862G wifi to DD-WRT linksys (repeater mode) wifi to 2530 (same as wired).
From TG862G wifi to DCS-933 (wifi extender mode with separate ssid) wifi to 2530,
(IPv6 works but takes a minute to load stream, IPv4 is stable and quickly loads and streams but does disconnect about once every 2 or 3 hours, again the motion grid and detection issues remain.)
From LGMS550 phone hot spot wifi to 2530 (IPv6 works but is slow to load sometimes, IPv4 is stable and fast, motion grid and detection issues remain.)
(Also I did try disabling wifi on the TG862G with the wired routers that had their own wifi, no difference.)
Note, my DCS-2630L can connect to the TG862G wifi using IPv6 without issue most of the time, and does not have the motion grid issues of the DCS-2530.
Connecting to the DCS-933 extender on IPv4 seems to be the better way currently for me.
