    I have an extra WRT54G and was wondering if it could be used as an AP. I would like to extend my wireless network. Can this be done?

    Yup. Simply run a cable to a LAN port the the WRT & leave the internet port alone. You'll also want to disable the DHCP server in the WRT. ;)

    Hi, I have a WRT54G V3.1 router, and would like to operate it on a large /21 network as an Access Point.

    Unfortunately I can't set the proper netmask (, 'cos there is only a fixed list of netmasks, and this isn't in the list.:( I also tried the Freeman 1.0.4 firmware, but the situation is the same: i can't edit the netmask manually.

    Any idea? I think it would be a very stupid error from linksys, if I couldn't use this router. In this very sadly case, the whole thing is a crap for me, I can't do anything with the hardware.:(

    cascading routers

    the setup is possible but it's not guaranteed to work. just hook 'em both up with a CAT 5. maximum length is 100 meters. try to also consider the interference between the routers. true enough, if primary router is, change secondary into and disable DHCP. usually you really don't need to set secondary to router mode under the advanced routing subtab in the router setup page. but you can consider it as an option. and since they both operate on the 2.4GHz, try setting the primary to channel 1 and secondary to channel 11. that way there's just a slight chance of frequency overlapping. keep the SSIDs different. you're good to go. you can also consult Answer 358 from linksys.com/kb their online knowledgebase. let me know if this works. by the way, is your primary router a WRT54Gv3.1 too?

    Re: cascading routers

    I don't really know, whether you wrote this as an answer for my post, if that's true, I think we misunderstood each other.

    So, I'm operating a /21 network, there is ~1200 UTP endpoints, and I would like to extend this wired network with a WiFi AP. I thought, this WRT54G could be used az an AP, but I can't set the proper netmask. I don't want to use NAT, so 192.168... IPs are not an option. If you have any idea, please help. Thank you.

    Using a firmware that gives you command line access to the router try entering the following command:
    ifconfig br0 <IP Address> netmask
    That should get you what you need, just make sure not to make any changes to the Setup page in the web GUI afterwards or the netmask will be overwritten. Note that I'm not sure why the Status page does not reflect the change...
