Title: DHCP function is just not working
Post by: xavier666 on September 07, 2014, 12:24:06 AM
Hardware B1
Firmware 2.04
Model DIR-605L

I tried many things, but it just won't work. I have around 5-6 devices but they are always assigned IPs serially. Tried from a different browser but no use.

"Serially"? Do you mean static IP address?

Internet Service Provider and Modem Configurations

Some things to try: - Log into the routers web page at 192.168.0.1. Use IE, Opera or FF to manage the router. Besure to log into the Admin account on the router.

I solved it. This was one of the most weirdest problems that I have ever came across!

Previously, I used an iBall roouter, and it had an SSID "XAVIER-WIFI"
After I bought the new Dlink router, I gave this new router the same SSID "XAVIER-WIFI"

After that, all the new devices had no problems in connecting to the new router (they were oblivious to the change of routers I think)

But this problem of DHCP remained.

So finally, I thought of changing the SSID (I don't know why I thought about this) and voila! DHCP is working. However, before this, I did a factory reset.
It's a weird problem with an even weirder solution!

Thanks for all the help. Notify the devs about this bug.

What did you change the SSID name too?  ???

To anything other than my previous SSID. Right now it's "XAVIER-DLINK"

I should let you know that my PC was assigned the proper IP since it was not connected via WiFi and it recognized that there was a new router in the network. But none of the wireless devices were set properly.

Anyways, problem solved  ;D

BIG UPDATE

I was wrong about changing the SSID to fix the DHCP

It was something else. It seems that if I change the computer name in the DHCP reservation list, then DHCP reservation does not work.

Meaning that, the logic of DHCP reservation should be like

Code: [Select]
if (MAC_address_of_device == MAC_address_present_in_DHCPtable)
{
    assign that device the IP binded to that MAC address present in the table
}
else
{
     assign that device the first available IP from the IP pool
}

But instead, the logic is like this

Code: [Select]
if (MAC_address_of_device == MAC_address_present_in_DHCPtable && Name_of_device == Name_of_device_in_DHCPtable)
{
    assign that device the IP binded to that MAC address present in the table
}
else
{
     assign that device the first available IP from the IP pool
}

This is completely incorrect. Either allow us to change machine name, or completely remove that device name field  >:(
This needs a fix ASAP

What happens if you remove the reservation by fully deleting it and then re-apply the reservation with the new name value?

SO just by editing the DHCP reservation host name value and saving the setting causes the device to no longer work or connect?

What region are you located?

Problem still remains. The device is not assigned the designated IP. The device's hostname cannot be renamed for proper DHCP functioning

>SO just by editing the DHCP reservation host name value and saving the setting causes the device to no longer work or connect?

The device connects properly and performs like normal. It's just that it's not assigned the IP address mentioned in the reservation table

>What region are you located?
India

Did you perform a factory reset, load the FW file, factory reset once more then set up the router from scratch with out re-loading a saved configuration from file?

I have the same issue... I bought the router yesterday, everything is working fine apart form the DHCP resevation option. I wanted to give my playstation a static IP and I went on the configuration page, copied the IP, the MAC address and the name, which for the playstation is "--" and I also selected that name from the drop down list at the end. After the reboot  the playstation ends up with another IP address. If I set up IP 192.168.0.102 it has the IP 192.168.0.103. If I put in IP 192.168.0.103 the router is assigning IP 192.168.0.102. Is there a fix?

Are you inputting a "static" IP address ON the PS or setting up a "reserved" IP address ON the router? Static and Reserved are two separate things.

After you set up a "reserved" IP address ON the router for the PS and saved settings and rebooted the router, did you reset and reboot the PS as well?

Please to the following in IE or FF:
Factory reset using a wired LAN PC, Load the same FW file, factory reset once more then set up the router from scratch with out re-loading a saved configuration from file. If the problem still occurs after this, I recommend that you phone contact your regional D-Link support office and ask for help and information regarding this. We find that phone contact has better immediate results over using email.
Let us know how it goes please.

Yes, but it did not change the behavior of the DHCP, the bug remained

I did not change/apply any firmware.
I did not load any configuration file
All I did was
  • Perform factory reset
  • Configured all the details of the router manually
