    [Resolved] Simple Wireless Ethernet Bridge Woes

    Hello all,

    I'm trying to connect my router to another router in wireless ethernet bridge mode.

    The setup is very simple. The 1st (WAN) router is and I want to connect to a 2nd router with a computer attached to a LAN port.


    internet >wire> WRT54G1 ( >wireless> many computers

    wrt54G1 >wireless (ethernet bridge mode)> WRT54G2 >wire> one computer

    I hope the diagram makes sense.

    I'm trying to use the wireless ethernet bridge mode, but have not been able to connect the two routers together!

    I can neither access from nor vice-versa.

    I have attached the basic/network and overview diagrams from my 2nd router (the

    Can someone please outline the process for connecting my routers briefly?!

    I also (ideally) want my computer (the one that will be connected by wire to WRT54G2) to have a static IP on the LAN and have ports 16000-17000 forwarded from the internet (I *should* _hopefully_ be able to set this up if I sorted out this IP stuff which I don't quite understand apparently).

    Both routers are running the latest tomato.

    I have attached pics to this post from WRT54G2 (the wireless bridge mode router).

    My wireless settings match perfectly by the way - it's something with the IPs that's wrong.

    The "overview" page on WRT54G2 is showing wireless connection if I understand correctly (see picture), but by the way I can't see it on the "device list" on WRT54G1... I don't know why. Any ideas?

    Please help!

    I had some grief with this recently as well, the solution was to make sure the bridge router was set to WPA Personal only - WPA2 seems not to be supported in this mode.

    Umm... sorry to be such a pest, but I don't want to set up the WRT54G2 as a wireless client (on a different subnet) but keep everything on the same subnet.

    Also, the faq is extremely informative and nice, but can you please point me where there is info for a wireless bridge? I can't find any at first glance.

    What is wrong with my settings (attached pics)??

    I really appreciate all the help.

    Edit: THANK YOU for the WPA2 tip! I switched the mode to "WPA Personal" from "WPA/WPA2 mixed" and it worked?!!! I guess it explicitly needs to be not on mixed on the client side...

    I'm writing this from my computer over the LAN connection right now ;-D

    Now on to port forwarding... Hopefully I'll work everything out with that ;-)

    (I hope this helps someone else - use WPA Personal explicitly in wireless bridge mode)

    Glad it helped, I probably wasted a couple hours before I thought to change the security mode. Static IP and port forwarding work as if the PC were wired directly to your AP router so you should be ok with that.

    There are some known issues with WPA2 and WDS/CLIENT/BRIDGE... my understanding is that the video on the tomato website shows you how to config client and that the subnet would remain the same... the IP is handed out by the DHCP on the host router which would be in the same subnet... ???? sorry I couldn't help.

    Ditto. 2 hours wasted here too changing IP's, rebooting routers and "repairing" net adapter in windows xp... before I changed to "WPA Personal".

    Now port forwarding works beautifully as well - I just had to change the assignment of the static IP I had before to a new MAC address and that was it ;-)

    digitalgeek I'm sure wireless client mode would've worked too, but I really wanted to get it working in wireless bridge mode... and I got it. Thanks for your info too though.

    BTW that works here even without setting the gateway/dns servers - they're all zeros. I guess all that stuff is worked out automatically by the main WRT54G via DHCP.

    BTW I'm typing this through a VNC window (connection initiated remotely via forwarded port) and it's really snappy ;-)

    If anyone wants some more detail about my setup PM me and I'll tell you what I can.
  8. you have tomato on your wrt54g2 v1? if so what version?

    hi. what if the AP main router have security disable? I have to set wep personal even when the main AP dont have security enable?

    the question is because you tell that bridge client ethernet need to be set as wep personal. and I was told that the ssid chanell and security neet to be the same in both sides.

    I have connected to the AP. but I have not internet eacth i have tried. what could be doing Not to have internert. even when the AP has internet. ??

    thanks for your help

    Ok I am feeling very stupid now but how would you go about configuring the wrt54g2 v1 to work as a wireless bridge. I am currently using a dynex dx-wegrtr to hook up to my dsl modem and I just bought the linksys to work as a wireless bridge to connect some devices that are in a area of the house where the wifi signal drops off. Thank you for your help.
