Hi All,

I have an Archer D2 (latest firmware). I'm trying to add a new client (device) to the access whitelist. However when I add the new entry (MAC Address and Name) it gives me the message:

"This LAN host conficts with Exiting LAN hosts"

...or very similar, and it won't let me add the entry. It's an Amazon tablet but I don't think that's relevant. I already have a number of devices in the list, laptops, tablets etc etc. It's obviously this particular device which it doesn't like because when I add the entry, but put a slightly different, MAC address (1E, instead of 1F for example) it happily adds that entry, for a non-existent device!

I cannot find any entry for the real existing MAC address anywhere on the router, nothing in the existing client whitelist, nothing in the MAC binding list. It's as though the router has just got it into it's head the device entry already exists when it doesn't!!!!

Any help would be appreciated? (and yes I have rebooted the router many times)
