How to get D-Link D615 D4 to work as a WIFI Repeater
(To be refined)
Check the IP of router A by connecting to it by a cable (not wifi)...
for me this would be 192.168.0.1, a friend has it set at 192.168.1.254...
whatever it is, connect to it with Firefox...we will presume it's 192.168.1.254 here.
2) Check the range of DHCP, I will presume it's 192.168.1.100 to 192.168.1.199 (max 100 clients)...the reason we check this is so that we can avoid this range when setting a static IP to our laptop/computer later.
3) Disable wireless security on router A (this will be re-enabled later). Note: This may not always be required, but apparently it is...and you're reading this guide so perhaps you should!)
4) Ensure SSID is NOT hidden (again this can be changed later).
5) Give yourself (laptop/computer) a static IP of (for example) 192.168.1.99, with Gateway and DNS set to 192.168.1.254...
6) Now connect laptop/computer to router B instead.
7) Ensure everything is reset to default. For the dir-615 I suggest once it's turned on and booted up, hold down the reset button for 5-7 seconds. This will also default the router to 192.168.1.1 with the dd-wrt firmware installed.
Note: the wiki suggests a 30/30/30 reset, well that was less efficient for me, and of course just took me to the emergency room on stage 3...perhaps something "deep" was reset in the first 2 stages?
8) Change router B to an IP of 192.168.1.253, Gateway and Local DNS to 192.168.1.254...click APPLY.
(note: these numbers are a bit backwards IMO, I prefer: A at .0.1, B at .0.2, and me at .0.3 but hey!)
9) Login to router B again at the new IP from (8).
10) Before we start setting up the repeater bridge, you might want to check that router B can see router A...
you can do this in any mode except for Repeater Bridge (lol), so just go to Status/Wireless, down the bottom of the screen you will see a button labled "Site Survey"...click it, wait, you should see the SSID and channel number for router A...along with a bunch of random neighbours.
11) Start setting up your (soon to be) repeater bridge by going in the Basic tab:
WAN, Connection type: Disable
Router name: whatever
Local IP: 192.168.1.253 Subnet: 255.255.255.0 Gateway 192.168.1.254 Local DNS: 192.168.1.254
WAN Port: Assign WAN Port to Switch: tick this
Time Settings: whatever
12) Click SAVE only - note, we apply the settings later so only click save for now...
notice how DHCP dissapears from the menu, this is because we can get DHCP from router A if we so please.
13) Go to the Wireless/Basic Settings tab (note how we skipped the rest of "Setup" tabs for now):
Wireless Mode: Repeater Bridge
Wireless Network Mode: I use mixed because I know both routers can handle b,g,n (802.11)
SSID: must be the SAME as router A
Channel: must be the SAME as router A
Channel Width: 20 MHz
SSID Broadcast: Enabled (disable later if you want)
Network Configuration: Bridged
14) Go next to Wireless/Wireless Security
Security Mode: Disabled (we will enable it on both routers later)
15) Go to Services/Services
16) Go to Security/Firewall
First UNcheck everything except Filter Multicast
Now on SPI Firewall, set it to Disable
17) Go to Administration/Management
At the bottom of the page click Apply Settings
Basically the instructions are correct except for
1. The DHCP bits dont disappear by themselves, you need to disable DHCP
2. You do not configure a seperate VLAN in the wireless bit..
