Hi together !
currently I´m one step before the decission to throw everything away

- I´m loosing nerves in assigning my DAP-2553 Access Point a
Dynamic IP Adress via DHCP and it doesn´t work.
PLEASE HELP me, I will describe my problem in detail:
The DAP is not new, but it has been set to it´s factory defaults and it´s latest firmware is also running in it.
I´ve to change the default static IP which is 192.168.50 to dynamic IP.
Here it starts - HOME SCREEN

then I go to BASIC SETTINGS > LAN

after this I change the mode to DYNAMIC via drop down

static IP freeces, mode has been set to DYNAMIC, next step is CONFIGURATION > SAVE AND ACTIVATE

..a reboot is necessary

thereafter the device has got it´s new dynamic IP "192.168.100.250" from the DHCP server, this is apoved because I had to change the IP in the URL to reconnect to it...

and all other network information was delivered as well

so far so good - if i now RESTART or POWER DOWN the device, the IP is automatically set back to factory default 192.168.0.50.
I´ve tryed it many times, with an other DAP-2553 as well, also with chrome or IE9 - same result.
Can you tell me my mistake please? Or what should I do??
Thank you !
Stefan
