@Ari,

The quickest think to try is to set your IP/mask/DNS/Gateway manually for your wireless connection. See if that does it.

I have a WRT54GL router in my one ethernet-socket-student apartment. The internet connection is provided by the student union, and I have no access to the main router, it’s just like a black box, and all I have is a single ethernet socket in my apartment.

To try to make things a little better for me and my roommate I wanted to setup my Linksys router so that it works as both ethernet switch (because we have an ethernet connected IP-phone) and as a wireless access point for our two laptops. So now you know what I want to be able to do (get both wired and wireless to the internet through my WRT54GL).

The wired network works fine, I can connect both laptops and the IP-phone to that one, by turning off the WRT54GL’s DHCP server, but I don’t want the only wired network.

According to your article (and, now, my bitter experience) it doesn’t work to let the WRT54GL’s DHCP server manage the wireless since it broadcasts it’s own IP address as the default gateway (which is not the student union router’s default gateway, so that doesn’t get me to the internet), and I don’t have the option of having a server in my tiny apartment, running a dedicated DHCP server, so my most important question is:

Isn’t there a third way of getting DHCP assignments to the wireless network with broadcasting an arbitrary default gateway??

I have looked at third-party firmwares for the WRT54GL, looking for clues to whether these firmwares can do what I need, but by my (admittedly rather short) inspection it seems that either it’s too trivial to mention in the “Capabilities”-section or they just can’t.

Can you verify or debunk my theory that this is in fact possible with DD-WRT or Tomato or some other third-party firmware??

Am de 2 ani acest router, am pus dd-wrt si merge super in configuratia de AP. Singura problema a aparut recent cind am vrut sa il accesez remote din afara LANului. Router este disabled evident (ai uitat sa mentionezi pentru cei mai incepatori), valoarea portului ptr webgui a fost schimbata de la 8080, noua valoare a fost introdusa in server la iptables ptr port forwarding si totusi nu reusesc sa-l accesez.
Teoretic ar trebui sa fie asa cum spune si la help, http://adresa.ip.server:port, unde adresa.ip.server e IPul dat de provider iar port este valoarea schimbata de mine. In LAN il pot accesa fara probleme (cu adresa lui interna) dar din internet nu merge. Si ma roade pentru ca stiu ca am facut totul bine in server si in WRT54, e posibil doar sa fi uitat sa pun sau sa scot niste bife pe undeva.
Sfaturile pentru securitate sint foarte bune doar ca eu il folosesc pentru clientii terasei si securitatea e 0 (decit sa stau sa explic la blonde cum se face conectarea cu pass mai bine las secu jos).
Ce-a zis Cris voi incerca si eu sa fac si exact asta m-am gindit ca face, un extender la reteaua mea.

Hi Cris, First of all, no questions are dumb. Secondly, if you only want to extend the range of your wireless, opt for a Wireless Extender. Cheaper and easier to setup. No need for a second router. In theory, you can connect another wireless network to your Linksys WRT54G router (via wireless) by installing 3rd party firmwares such as DD-WRT which enables the "Wireless Distribution System" or WDS within your Linksys WRT54GL. Make sure you do understand the performance and security limitations before going this path. If you want your 2 networks (meaning different subnets) to be connected, the easiest way is to connect each WAN interface of the WRT54GL to a 3rd wired router (also a Linux server with multiple NICs will do) and setup the routing accordingly.

Sorry for a dumb question but what do you mean “Wireless router can also be used to connect 2 or more wireless networks”
Can I use my Linksys WRT54GL to connect to a wireless network and forward the signal further, acting like a wireless amplifier?

There’s a fine line between ergonomic and lazy. However, I manage not to cross it… and remain in the lazy zone.

It’s D-Link for the fun of letting hacker-wannabe-dumb-ass-neighbors trying to get free internet.

@h:
You type only once. The settings are saved.

As for the SSID name, why not “Vodafone_Public”?

Hiding the SSID may be a good measure, but if you have WPA2/AES you may leave it unhidden. If you have a good key, you’re safe. It’s less typing if you’re connecting with a mobile phone or other device without a comfortable keyboard.

Another good security measure is good to disallow administrative access
from the WLAN.

I also have the WRT54GL model. I set the SSID to D-Link. No reason.
