Is it possible, to use the internal antenna of a WBS210 to connect over 2.9km AND at the same time to use one of the external antenna connectors to have a little local wifi?

The CPE510 is outside on the roof, so there is no sense that the leds are on. Sorry, that was my failure! I mean the WBS210 not the CPE210.

Thank you for your answer! I hope this are my last questions ;-) Is it possible to switch the LEDs off on the CPE510? For which distance can I use the CPE210 without antenna?

And can I connect on the LAN Port my PoE Camera und only supply the CPE510 with power on his PoE port? Do you now a power supply for this router that looks like a LAN cable but has only the power and...

OK, I understand. But can I use this port also as switch directly?

The CPE510 has 2 LAN Ports, one is used for POE and for what can use the other port? Can I use it also as switch?
