hi guys,

used to use a linksys WRT54GL router coupled with a adsl2+ modem for my internet connection and wifi needs. However, parents have just upgraded to Orcon Genius, which has its own wifi, modem and phone stuff.

So i thought i'd use the linksys WRT54GL which is running Tomato firmware, as a signal booster, and as a point to plug the TV in via wired LAN. The genius box is downstairs, and the TV is upstairs.

My problem is that having set the WRT54GL to the same settings as the genius router, (different channel though), its not seeing it as one network. It seems that if the linksys is off, i can connect to the orcon (and thus the internet) but when i switch the linksys on, i cant get internet, so can only log into the linksys.

orcon is setup as 10.1.1.1 and is DHCP server
have linksys setup as 10.1.1.2, DHCP server disabled. is in Acess point and WDS mode.

both have same SSID, same password, same seciurity protocol, just different channels (6 and 11)

any advice to help fic this would be awesome

cheers

WDS requires setup on both units. If that isn't an option, try Universal Repeater mode.

I assume you have the Linksys plugged into a LAN cable from the Genius (into a LAN port not the WAN), in which case you should have WDS disabled.

If you're trying to use WDS you'll need to clarify if the Genius is compatible with Linksys WDS, and if so it needs to be on the same channel.

I had a similar setup for a while, but I abandoned it because of bandwidth and reliability issues. It would drop the connection randomly, and couldn't get more bandwidth than a standard dev video required - I couldn't do 720p.

In the end I ran a cable to the 2nd router, used it as a switch for the TV/PS3, and made a WAP with a different name on a different channel from the other WAP in the house.

What Steve said. It's a common misconception that WDS works across all brands. It doesn't, everyone implements it a litle different.

While it is inferior to WDS, Universal Repeater requires no setup on the "main" AP, as it simply acts as a wireless client. Plus it works across brands for the same reason.

Also, wireless links between floors are tricky business, as the antenna on most APs are designed for horizontal transmission. This will be particularly troublesome if the APs are roughly below each other, rather than on opposite ends of the house.

hi steve - my setup is as follows - motorola cable modem by TCL with static IP, router connected to the WAN port with the static IP as given by TCL. I have another modem/router which I would like to use as an extension of the router - in which case i need to connect the LAN port from the router to the WAN port of the modem/router correct? I see the Internet led blinking on it but it doesn't allow me to connect to the internet using my wifi phone?

cable modem --- router --- modem/router

I just want to use the wifi of the modem/router and bridge the WAN and the WLAN port? is there something special I need to do?

current setup of cable modem --- router works fine.

appreciate your help. let me know in case you need any more details.

cheers!

You plug a LAN port of the main router into a LAN port of the 2nd router, not the WAN port. Then you set it up as a WAP, no DCHP. There's a guide to doing this on the dd-wrt website.

thanks for the quick response - i did try connecting it to the LAN port but didn't disable DHCP or give it the LAN port an IP address.

I will try this tonight and see how it goes. I know it was clear on the post to use the LAN port on the 2nd router - but for me it just didn't make sense as the 2nd router needs to give out IP addresses to all the devices that connect to it and hence it needs DHCP enabled. The WAN port made more sense as you would then have the 2nd router translating all the secondary IP addresses to the 1st router (which has a static IP)...

I will setting it up in the way explained in the link you sent to me and I will try to learn how it works later :)

You don't want the 2nd router giving out IP addresses, you want DCHP passthrough. It's set up as a transparent bridge really. Mine's just a switch and WAP for my TV, PS3, and wireless devices. It doesn't do anything smart. I don't use DD-WRT on my 2nd router, just whatever came on it - it's a D Link I think.

This setup causes double NAT which you want to avoid at all costs.

Double NAT, and multiple DHCP servers. Two things that'll make any network engineer kill a sysadmin.
