range extender and mac addresses

I've recently been trying to use an Edimax EW-7438RPn (v1; it was going  
cheap and has been in the bottom drawer for a while :-)

My dhcp server is complaining about IP's moving mac address unexpectedly:

Jul  4 09:19:37 data kernel: arp: 172.16.254.16 moved from  
80:d2:1d:0b:b8:3b to 80:1f:02:b1:bb:94 on re2
Jul  4 09:09:14 data kernel: arp: 172.16.254.16 moved from  
80:1f:02:b1:bb:94 to 80:d2:1d:0b:b8:3b on re2
Jul  4 08:44:08 data kernel: arp: 172.16.254.16 moved from  
80:d2:1d:0b:b8:3b to 80:1f:02:b1:bb:94 on re2
Jul  4 08:43:47 data kernel: arp: 172.16.254.33 moved from  
f0:db:f8:81:8f:44 to 80:1f:02:b1:bb:94 on re2
Jul  4 08:43:05 data kernel: arp: 172.16.254.16 moved from  
80:1f:02:b1:bb:94 to 80:d2:1d:0b:b8:3b on re2
Jul  4 07:58:14 data kernel: arp: 172.16.254.16 moved from  
80:d2:1d:0b:b8:3b to 80:1f:02:b1:bb:94 on re2
Jul  4 07:57:17 data kernel: arp: 172.16.254.16 moved from  
80:1f:02:b1:bb:94 to 80:d2:1d:0b:b8:3b on re2

(80:1f:02:b1:bb:94 is the extender's own mac address)

I thought wireless kit simply passed through the client's mac address;  
it seems the edimax doesn't, and these messages reflect the wifi client  
swapping between access point and extender. Certainly, the networking is  
very glitchy [but only] with the extender turned on, so something's amiss.

Am I misunderstanding something, or is this proper behaviour?

If the device is faulty, I notice dire warnings at edimax about flashing  
a v1 device with v2 firmware (which is all that's around now). Has  
anyone tried this (successfully :-) ?

And has anyone any experience with the maginon wlr-510 wireless device?  


TIA.
