@archerboy not sure if you are having the same problem, but there is a major design flaw of the Archer software. It will allow you to assign a name to reserved IP's with spaces in them. But the spaces will cause a DCHP error and will stop assigning IPs.

Thanks for the workaround to this bug. TP-link, this needs to be fixed! I was ready to return the router but stumbled across this page to find this is a very old issue for this router.

@Norcalkev 

Glad that help. This is a long time issue that TP-Link should resolve with a firmware update. But this is a workaround that makes a great router work as it is expected to.

My C-4000 did the same thing yesterday after changing one of the reserved devices. None of the non-reserved wireless devices were assigned DHCP IP addresses anymore. I called tech support and they just had me reset the router to factory defaults. After having to go through setup all over again, when I tried reserving some IP addresses, I lost all the DHCP devices again. I'm sure that I probably used some device names with more than one contiguous word. Interesting that TP-Link's tech support department does not even seem to be aware of this firmware issue.
