connecting two CPE210
I having a hard time connecting two CPE210 over like 30m line of sight. To make this clear, nothing is blocking it, the signalstrength and quality is perfect, I can even lower the power alot and still have the same linkquality.
The problem is: after some time like 30minutes, sometimes after a day the 2nd CPE210 that is sitting on the outside-location loses it's IP. The Host-CPE210 that is connected to the LAN still shows a connection to the second, but the second's webinterface can't be reached. And also there is no response on the second CPE's LAN-port (checked with nmap).
My best bet so far: some odd DHCP-lease failure that erases the IP somehow or just a plain hardware-defect. The LAN-cable is okay, checked that with a tester already, PoE working too, of course.
Is there a recommended configuration for connecting two CPE210 to a local LAN? Perhaps something that os fool-proof and won't britch with the local DSL-router?
Oh and just another thing: I noticed it is possible to activate the second wifi-antenna to host a second wifi at the outside-location, it won't be a perfect signal but good enough to eg. connect a phone for messaging. Could this be a problem-source, too?
Looks like I just need a "this should work regardless of the local LAN"-config to make sure I'm not the error? :)
