When the TS-7800-V2 is properly set up to acquire wireless network automatically, if that network acquisition fails due to the network being unavailable during boot, the TS-7800-V2 will experience a boot delay until the network acquisition phase times out. This timeout can add more than 30 seconds to the boot time.
If the network is not acquired during boot, the TS-7800-V2 may eventually still re-acquire network without a subsequent reboot.
