vladix · October 24th, 2009, 08:24 AM

I replace airlive 5470ap for d link dir 615 d1 revision... all work good but i have problem with dhcp server. In the first 10-12 hours working ok, but suddenly router dont sent ip to new connection client (limit or no connectivity - msg in windows). Why I dont know...I upgrade firmware to 4.11 but same problem. Then I reboot and dhcp works. In DHCP Reservation are 4-5 my devices. What is problem ? Can someone solve ? Thanks and sorry for bad english.

Are you connecting by wireless or physically plugging into the router with cat 5 cables?

What if you remove the reservations and allow a machine to get a random address? Does the problem still occur?

What do you have your DHCP pool set too?

same problem continues... I insert few devices in dhcp reservation, their working ok some time (1-2 days) then if disconnect from network I cant connect again over dhcp... only work static setting. Devices that are not in dhcp reservation list also cant connect to dhcp (limit or no connectivity, no gateway etc) ... when reboot dlink all work excellent. dns relay is on. adsl modem huaweii is in bridge mode... I change firmware on 4.10, same thing...I try 4.11, 4.0 ...
