After a month of testing and communicating with Unifi Support. I am able to estimate the fault of the slow down, inconsistent loss of signal of the DLink Wireless router. It seems that DLink router manual did emphasize the thickness of wall and corners that will affect the signal .
i was wondering if i can use my innacomm router to collect the signal from DLink router upstairs to improve the connectivity and consitency . the Dlink user manual mentioned of connecting to another router as describe at the bottom.
D-Link DIR-615 User Manual 9
Section 2 - Installation
If you are connecting the D-Link router to another router to use as a wireless access point and/or switch, you will have
to do the following before connecting the router to your network:
• Disable UPnP™
• Disable DHCP
• Change the LAN IP address to an available address on your network. The LAN ports on the router cannot
accept a DHCP address from your other router.
To connect to another router, please follow the steps below:
1. Plug the power into the router. Connect one of your computers to the router (LAN port) using an Ethernet cable.
Make sure your IP address on the computer is 192.168.0.xxx (where xxx is between 2 and 254). Please see the
Networking Basics section for more information. If you need to change the settings, write down your existing settings
before making any changes. In most cases, your computer should be set to receive an IP address automatically in
which case you will not have to do anything to your computer.
2. Open a web browser and enter
http://192.168.0.1 and press Enter. When the login window appears, set the user
name to admin and leave the password box empty. Click OK to continue.
3. Click on Advanced and then click Advanced Network. Uncheck the Enable UPnP checkbox. Click Save Settings
to continue.
4. Click Setup and then click Network Settings. Uncheck the Enable DHCP Server server checkbox. Click Save
Settings to continue.
5. Under Router Settings, enter an available IP address and the subnet mask of your network. Click Save Settings to
save your settings. Use this new IP address to access the configuration utility of the router in the future. Close the
browser and change your computer’s IP settings back to the original values as in Step 1.
