Ethernet Bridge with DD-WRT - Router now bricked?

post #1 of 12
Thread Starter 
I have a D-Link DIR-615 router running DD-WRT, and I've been trying to configure it as a wireless bridge for the other side of the house.

Our network consists of a VM Hub (Netgear VMDG280) (router/modem), which links via Ethernet to a Belkin F5D9230 (for 802.11g - dad's laptop is the only PC that won't pick up the Virgin network). All devices go through the Belkin due to lazyness in network setup and ease of file and printer sharing.

I wanted it set up so that the DIR-615 went into my workshop, wirelessly linked to the VM Hub, and the D-Link then would connect Ethernet devices (specifically a ThinkPad X31 with a dead wifi card and a Tiny desktop, both running Ubuntu 10.04).

So I followed a guide on how to do this, and it didn't work. It got a WAN IP from the VM Hub, but wouldn't connect to the internet.

So I reset, and tried again. Same problem. Reset, try again. This time, no WAN IP. Reset, try again. This time, I can't get into the router. The computer (configuring it from the Tiny) connects, but 192.168.1.1 (default DD-WRT IP) does not work. Nothing does. The router is inaccessible, even after resetting to factory settings (I tried repeatedly).

Is it bricked, and is there another guide out there that works? This D-Link isn't very old, will they let me RMA it (bought off eBay, so would rather RMA with D-Link if possible)?

do you do 30/30/30 resets?

I just do soft resets, which usually restores it straight back to stock DD-WRT. What I do is

Power off. Reset hole for 5 seconds. Power on. Release reset hole after 5 seconds. It usually works.

I did try one 30/30/30. But I didn't time it or anything, I guessed, and my judgement of time is a bit crap. So I will try and do a proper 30/30/30 tomorrow.

30/30/30 fixed it, it's working. But I cannot for the life of me get the D-Link to work as a repeater, client, or bridge. It just won't get a WAN IP from the Virgin hub.

The VM Hub is on 192.168.0.1
The Belkin is on 192.168.2.1
So I'm keeping the D-Link on 192.168.1.1
I follow this tutorial, can't see where I'm going wrong.

Right, I'm now following a video tutorial.

The VM Hub is made by Netgear, and it's security is set as WPA-PSK[TKIP] + WPA2-PSK[AES]

So, what do I set the security as in DD-WRT?

OK, it's on, connected, I can access the internet, it is repeating the wireless and wired connections for the VM Hub.

But the speeds are terrible. On the Belkin, I can get 9-10Mbps. On this, it varies between about 0.01Mbps and 6-7Mbps. How do I sort this?

Try it with WEP. I used the old 54g white netgears that VM sent out, but I had to flash the firmware to the stock netgear (rather than the custom VM version) to even access the repeater function. Even then it was restricted to WEP.
What's your latency like (ping)?

Ping never exceeds 30ms whatever option I choose.

I should rephrase it. The D-Link, repeating the Virgin, has the speed issue. I got so frustrated I unplugged the D-Link, and am connected to the Virgin now and it's the same speed as the Belkin is.
The Netgear and the D-Link are both capable of WPA2 (the chosen security method).

Would it be easier and less stressful to run down about 30m of Cat 5 and use the D-Link as a switch?

odds are you just locked yourself out of the router
turned off dhcp/changed its ip and cant access its setup page
its tough to brick dd-wrt

for setting it up as a repeater/bridge
first change its ip to a different subnet than your router like 192.168.200.1
manually set your pc ip to 192.168.200.2
log into the dd-wrt router 192.168.200.1
then disable dhcp and view its status-wireless-site survey
find your wlan and join
pick on wireless then security
add your mode and password

pick on save settings and apply

They're both capable of WPA2, yes, but are you sure that they're capable of WPA2 whilst in repeater mode? Going back to the example of those white WGR614 routers, they are capable of WPA or WPA2, but not when in repeater mode.

I've always though repeaters usually work best when you have identical models, but I suppose with some luck you can get different models to work too.

Have a read through this to see if it helps: http://www.dd-wrt.com/phpBB2/viewtop...c94686cfc2d6f2
There's a post on page 4 that may be of particular interest to you:

Thanks for the step by step instructions.

I got my DIR-615 D4 to work by following all but one of the instructions.

The one I didn't follow was the one where I had to add a Virtual Access Point (VAP).

After lots of trial and error I got it to work and I tried different configurations such as:

40mhz
Enable SSID / Disable SSID on pysical wireless interface
Same channel on both routers (auto worked fine when i used 20mhz)
enable and disable mac cloning.

What I want to know is will my wireless devices be able to switch to the D-Link router (the repeater bridge) even though I haven't specified a virtual interface? By not specifying a VAP, am I just saying to the router that "you are a copy of the main router so you don't need a VAP of your own"?

My main router is a Netgear Wireless N from Virgin Media (VMDG280)
