I have an AM200 router and WRT54GL router which I cannot get to work together in half bridge mode. The problem is the WRT54GL does not pick up the IP address from the AM200 router. If I plug the AM200 straight into my PC it correctly passes my ISP IP through to the network card. If I plug it into the router it never receives the IP. I have tried different firmware (Tomato and DDRT)

AM200 settings
PPPOA
VPI 0
VCI 38
Multiplexing LLC
MTU: Auto
Half Bridging Enabled
IP Address: 192.168.1.1
Subnet: 255.255.255.0
DHCP: Enabled

WRT54GL Settings
WAN - Auto Config - DHCP
MTU - Auto
IP Address - 192.168.1.2
Subnet - 255.255.255.0
DHCP: Disabled

Does anyone have any ideas?
 
Thanks for the information eXor but just as you posted I fixed the issue by doing a hard reset on the router.

I used these steps to reset ....
1. Press and hold the reset button for 30 seconds.
2. Then, unplug the power keep holding down the reset button for another 30 Seconds.
3. Plug back the power back in, and keep holding down the reset button for 30 Seconds.
4. Release the reset button.

Make sure that the power light should get solid after reset ....
 
Half bridge is no longer a hack on the AM200/WRT54GL. The latest fw for the AM200 fully supports half bridging :) The problems you had, Lankio, were probably due to you having the AM200 and WRT54GL in the same IP range ;)

My AM200 is set to PPPoA, half bridge, IP 192.168.100.1 and the WRT is DHCP with an IP of 192.168.1.1. Easy peasy, and this way you get to keep access to the webUI of the AM200 even once the bridging is up and running :)

OOO! Didn't know that. I'll go and grab the latest firmware.

Edit: Hmm 1.19.02 Already have that.

Thanks for the confirmation. I've just emailed Linksys to ask if they can email me a copy along with the changelog. It's quite a poor show that their website is not one but TWO versions behind the latest firmware :mad::(
 
I know what you mean; when I was originally trying to sort my problem out I thought about flashing the firmware but when I couldn't download the latest version I decided against it.
 
FWIW the Linksys AM300 is on firmware .04 - maybe the OP made a mistake with his model number? Or maybe Linksys sent him the wrong fw? :confused:
 
I have my am200 in full bridged mode, set my WRT5g to my static (or dhcp as i dont suppose it matters).
 
Hi all
Where did you get the AM200 1.19.04? I searched everywhere (but where it is, surely) and I just found 1.19.04 for the AM300. Althought, I flashed my AM200 with the AM300 1.19.04 and it works but it did not solved the issue I meet (seldom deconnections I even can't remount with the "CONNECT" button. I need to make a device reboot.)
Now, my AM200 web GUI shows Software version 1.19.04 ADSL Modem AM300, unlike in Lankio's post.
I'd rather like to use the AM200 1.19.04 to remove the unusefull USB stuff inside the AM300 fw.

Bye and thanks for help
 
I run my am200 in full bridge mode and somebody kindly on here gave me a script for the routing on the am200 so i can still access the console.

am200 = 192.168.1.x
wrt54g = public + 192.168.2.x

heres the thread: http://forums.overclockers.co.uk/showthread.php?t=17885217&highlight=username_sp00n

The script:

Code: 
iptables -I POSTROUTING -t nat -o vlan1 -d 192.168.1.0/30 -j MASQUERADE
ip addr add 192.168.1.2/30 dev vlan1 brd +
Works perfectly :)

Props again to eddietop for the help on that one :)

Thanks Sp00n, but this is not the way the problem is troubling myself: the modem and router are in a remote location, so when the connection goes down, I have no other solution than starting my car to go there. I'm now checking if a keepalive with a ping each 20mn to a remote public IP from the wrt54gl (dd-wrt v24sp1) will help, because it seems the connection goes down some nights when there is no traffic (the keepalive redial from the modem each 20mn did nothing).
Although, your setting is interesting myself because I forgave any full-half bridge because I couldn't get access to the modem console anymore (as there is no https nor ssh on the modem, I disabled remote access and I want only to have access to it by temporaryly re-enable a NAT rule (in the WRT set as DMZ) if I ever need to access the modem remotly. How do you run scripts on the AM200?... it seems I have to search some open fw for it, isn't it?
[EDIT] Ok, I found the script from Eddietop you spoke about. It runs in the wrt. cool

New issue with the AM200 (fw am300 1.19.04) : some days ago, I couldn't get access anymore to the modem. Once at the location, I found it was fully reset to factory defaults. Does anybody here already met this bug?

Bye
