How to get D-Link D615 D4 to work as a WIFI Repeater

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, a friend has it set at

whatever it is, connect to it with Firefox...we will presume it's here.

2) Check the range of DHCP, I will presume it's to (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), with Gateway and DNS set to

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 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, Gateway and Local DNS to 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" 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: Subnet: Gateway Local DNS:

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

Click Save

14) Go next to Wireless/Wireless Security

Security Mode: Disabled (we will enable it on both routers later)

Click Save

15) Go to Services/Services

Disable DNSMasq

Click Save

16) Go to Security/Firewall

First UNcheck everything except Filter Multicast

Now on SPI Firewall, set it to Disable

Click Save

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..

VNC on Mac

MountainLion's inBuilt VNC server sucks.. Keeps crashing, not responding etc..

Solution, use a different one.. The best one Ive found is RealVNC, works a treat on Macs..

Creating a Media Server for home

Well recently I've managed to blag myself a nice little HP Microserver (N40L) for home server use from Its a nice little server, not too powerful, not very noisy  and integrated raid 0 & 1.. Perfect me thinks..

Until now I've been running my trusty old Joggler running Xubuntu with a USB Hub connected to a printer, harddrive(s) and keyboard/mouse combo.. It worked well, but wasn't really powerful enough to do media transcoding , fast file transfers etc...

So now the Microserver... Which Distro??

Initially I thought Id try Amahi or OpenMediaVault, Amahi is now built on top of Ubuntu, which means I can install other products easily, and OpenMediaVault is built on debian.. I also tried Zentyal, which again is installed on Ubuntu Server 12.04LTS, and installs everything.....

Eventually after rebuilding the server many times I've settled on... ... Vanilla Ubuntu and installing the products manually. Why??

  • Amahi
    • Nice product, easy setup however most things I want it to do I need to "Pay" for a add on, even though the add-ons are opensource and free.. Now the way it works is that yes the add-ons are free, but the payment is to pay someone to write the packager and maybe a UI to administrate it, also to support the project itself.... Now Im not against that, or paying, but not when I can do it just as easily myself... 
  • OpenMediaVault 
    • Didnt go for this in the end as it was based on Debian, and I kinda like the idea of being Ubuntu based simply for the software centre support etc... 
  • Zentyal
    • I really liked this install, it had different versions (office, gateway etc) but no "home" install. The closest I could use was "office", however that wanted to install LDAP etc, something I dont need at home... Also when I tried to install it Samba wouldnt install properly (something to do with mismatched versions/dependancies...), I spent some time on trying to fix it and then gave up....
So yes eventually I settled on basic Ubuntu 12.04LTS(although I might upgrade that to 13.04 when its released soon)..
Current set of products installed
  • Ubuntu Server 12.04LTS, better than Ubuntu Desktop as it has less desktop software installed
  • Ubuntu Desktop , need this so when you VNC you have a gnome desktop or something 
  • VNC Server, for remote desktop
  • WebMin,  simple admin tool for adding users, groups, samba shares etc
  • Samba, for network sharing to windows devices
  • Oracle Java, needed by software like Serviio
  • Serviio, DLNA software, works a treat!, also needs a collection of renderers decoders etc installed
  • ssh-server, Already installed I believe,  but needed for ssh access
  • lm-sensors, to monitor the machine
  • ssmpt, simple emailer
  • Apache, already installed as part of server, but need to configure a "admin" landing page..
Future products
  • Squeezebox server
  • Maybe LTSP, Linux terminal Services, instead of VNCServer
  • transmission bit torrent client

My next blog posting will detail what software I installed, and basic configuration. Virtually all of it requires nothing more than a collection of apt-get's and the hardest bit was ensuring you have all the "pre-requisites" installed.. Thankfully simply googling "Install Product X" was sufficient for this..

The blog posting will almost certainly simply contain a list of headings, a link to docs to install that component and then some notes... I'm half tempted to write a script which will do all the apt-gets , installs etc....
