How to extend your Linksys WRT54G with AE

First, my thanks to Suspect0, Henry B and moliu, who's original posts allowed me to finally, after making every mistake possible, successfully extend the range of my Linksys WRT 54G with my AirPort Express. I've taken all their info and added even more clarification to the steps. Follow closely and you too can accomplish this feat of modern wireless magic. Just for the record, my network includes a couple of Mac towers and a Mac PowerBook, all running OSX, 10.3.7. My final, successful run at getting the AirPort Express on-line was accomplished on the PowerBook.
1. First of all, firmware on the Linksys. To check your Linksys firmware, address the unit through your browser by typing its IP address - 192.168.1.1. Skip the "User ID" field, the default password is "admin" (no quotes). Look for the firmware version in the upper right of the Linksys window. As of the date of this posting, the latest version of the Linksys firmware is 3.01.3. That works. No special hacks, patches or upgrades needed. If you're not at the 3.01.3 level, you'll need to update your firmware. That's done by going to Linksys.com/Technical Support/Product Pages. In the pulldown menu chose Driver/Firmware. Under "Choose a Product," I chose WRT54G -- Wireless-G Broadband Router v2.2. Actually, all of the WRT54G choices seem to take you to the same firmware download - Firmware Date : 10/12/2004, Version : 3.01.3. Once you've got the right firmware, go back to your Linksys in the browser window, Under the Administration tab, choose Firmware Upgrade and follow the directions.
OK, on to your AirPort Express.
2. If you're like me you tried everything to get the AirPort to work before finding a step-by-step like this (again, thanks everyone). So, to go into this process with a clean slate, I suggest doing a Factory Default Reset. This is accomplished very simply by holding in the reset button on your AirPort Express while plugging it in. Continue to hold the reset button until you see the yellow light flash green four times. Let go and allow the unit a few seconds to work through its reset. If you don't feel you need to clean out all your settings, there are less severe resets described here -- http://docs.info.apple.com/article.html?artnum=108044. But, why take a chance? Use an Ethernet cable to connect the AirPort Express to your Linksys router.
3. Now, it's time to get some needed information from your Linksys. Hopefully you've still got that browser window open and you're addressing the Linksys. Now, I can't tell you "why" you need to do some things I'm going to tell you to do but, trust me, I read them somewhere, they worked for me, so I'm passing it along to you. For instance, the first thing you should do is, choose Wireless/Basic Wireless Setting and under the pulldown menu for Wireless Channel, chose channel 11. Name your network and be sure you remember the name you used exactly -- this is your SSID. Move to the next tab, Wireless Security. Most people suggest choosing 128 bit, WEP security, so that's what I did. Invent a passphrase and hit "generate." Write down the number generated under "Key 1." Be sure you've gotten it absolutely correct or you're gonna be hopelessly confused later. OK, one last thing, choose the Status tab. Under Status chose Wireless. Write down the Mac address. This is NOT, as I learned in a very time-consuming way, the Mac address you find on the bottom of the router, under the Router tab or under the Local Network tab!
4. Continued in next post ...

4. The whole reason we're going through this exercise is that the AirPort Express Setup Assistant doesn't work with the Linksys. You are forced to do a manual setup using the AirPort Admin Utility found in the Utilities folder inside your Applications folder. Though mine was up to date, I imagine it'd be prudent to run Software Update and be sure your AirPort Admin Utility is up to date. So, open the utility. The "Select Base Station" window should open. With any kind of luck you'll see your AirPort Express' default name. If there's more than one AirPort within range, select one and click on identify. The status light on the AirPort should flash. If you've got the right one, click "Configure." Choose the AirPort tab. Under the Base Station heading chose a name. This name will show up in the "Select Base Station" window once your configuration is complete. You can leave Contact and Location blank. Under the Airport Network heading's pulldown menu choose "Create a Wireless Network (Home Router)." In the name field, enter the SSID you copied down in part 3 (enter it exactly or you'll end up with two different networks!). Click on Change Wireless Security. Choose 128 bit WEP in the pulldown. Under Network Password, you're going to type in the "Key 1" but here's the trick -- proceed the key number with a dollar sign. Yes, "$." Don't ask me why, I don't know. But, again, it works. Type the same thing in the Verify box. Finally, change the channel to 11.
5. Under the Internet tab you'll see a pulldown menu "Connect Using." Choose AirPort (WDS). In the Mac Address window type in the number from step 3. Click "Also allow wireless client computers. Now, under Configure, you have a choice. It worked for me to chose "Using DHCP." Now, this has been something of an Odyssey trying to get the AirPort to work with the Linksys. I've read a lot of accounts and at least one other person trying to do this same thing said DHCP didn't work and it was necessary to configure manually. If, after following these instructions, you still have a problem, try a manual set up. The Router Address is 192.168.1.1, the Subnet mask is 255.255.255.0. The IP address is trickier. In one example I've seen 192.168.1.4 used but when I asked an expert I was told "... use one above the range of the lInksys DHCP server ,,, I suggest 192.168.1.201." I'm just passing this along.
6. Under the Network tab, deselect "Distribute IP addresses.
7. Under the WDS tab, check "Enable this base station as a WDS...: and in the pulldown menu "remote base station." Also check "Allow wireless clients on this base station." If all is working as expected, the Main AirPort ID box should automatically display the Mac number you entered in step 5.
8. Under the Music tab, if you'd like, select "Enable AirTunes on this base station." Under "iTunes Speaker Name" enter something appropriate -- Living Room, Poolside, whatever. This name will show up in an iTunes pulldown menu once your configuration is complete.
9. You're ready to click "Update" and load your new configuration into your AirPort.
10. Once the AirPort update is complete, disconnect the Ethernet cable, unplug your AirPort and move it to the edge of the network you're extending. Plug it in and watch the magic. After the AirPort resets it should go "Green."
11. If you're using your extended network to distribute iTunes you've got two more steps. You'll need to use an adapter cable to feed the mini out on your AirPort into your stereo. Launch iTunes and look in the lower right of the window. THere should now be a pulldown menu that offers you a choice of music destinations, either "Computer" or the name you entered in step 8 -- Living Room, Poolside, whatever.

By the way, I hope to post this "How to" in a couple of other helpful places so if anyone has any corrections or additions, email me at pete@petemay.com and I'll edit it.

Great post, Pete...thanks! I followed your directions & it works great! A couple of notes, though. I tried my setup without setting up WEP & it still worked. I'm not advocating running without WEP, I just wanted to see if it would work without it or not. Some folks might have an existing, non-WEP enabled WLAN that they want to try WDS out on without breaking their existing setup. Of course, running with WEP is better than running in the clear, if you can avoid it.

Also, I think the "$" is required when entering the WEP key to let the Airport Admin Assistant know that you're entering a hexadecimal number as opposed to a text string. I think newer versions of the program feature a pull-down so you can select the format of your WEP key (hex or text), instead of having to prepend the "$".

My application's a little different from yours. I need to connect a ReplayTV to my LAN, but there are no Ethernet jacks nearby. By using the AirportExpress in WDS mode, I can use it's Ethernet jack to connect the ReplayTV. The AirportExpress then bridges the connection over the air to my WRT54G, which I'm using like an access point on my wired LAN.

Streaming video works like a charm, even at "half" 802.11g speeds due to using WDS. Right now, the ReplayTV is the only device on my .11g WLAN (dedicated to channel 11); all my other wireless stuff is on my .11b WLAN, (with access points on channels 1 & 6), including another Airport Express that I use for streaming iTunes.

I think your solution here sounds similar to what I need for my network problems.

I have a Netcomm1300plus4 wireless adsl router at one end of the house. This router is connected to the net and allows some rooms in the house to connect through wired ethernet. The wireless side of the router will also work just fine with a friends airport enabled Powerbook and allows the light on my recently purchased Airport Express to glow green.
It also appears to allow connection to the internet through the airport express via wireless.

Unfortunately, I have an ibook without wireless which I want to use together with the Airport Express to connect to the internet.

I feel it should be possible to connect the Airport Express to the power and plug the ibook into the Airport Express ethernet port. Is this possible?

Pete,

Thanks for the great write up, I followed it this afternoon and I now have WDS up and running with WEP. A related question I now have is this.

On my Dell laptop I can see with both netstumbler and the dell wireless utility that I have 2 broadcast stations. When I move around the house, and especially to areas where one signal is weak and the other stronger, how does the switching take place? I notice that if I boot, my computer will lock onto the stronger signal, but is this possible to change manually with the system up? Also, I did not see it switch dynamically, but I assume it did as I found myself looking at the address of my airport instead of my router(linksys wrt54g).

Thanks in advance, Im trying to understand as much as I can about all this

Hi,

Just worked my way through your instructions and I am still having problems but I have no idea what is wrong. Everything appears to be ok because once I've finished the setup as you describe the express rests and the LED goes green however I cannot connect to iTunes and it is not visible from the Select Base Station window on my Mac. If I unplug the airport express is reboots and goes green but again, I cannot connect to it. Everything else on the network is working fine. I have three laptops (two Dells running XP and one Powerbook). Do you have any suggestions or where I can go for further help?

Feb 11, 2005 7:38 PM in response to petemay

sigh This almost sounds easy. However, my setup is a little different. I have a Mac Mini, cabled directly into my Linksys WRT54G. It connected with no problem and I get a great web browsing experience and successfully set up sharing for a wireless Windows laptop in my house.

I purchased the AirPort Express to stream iTunes music from this wired Mini via the Linksys wireless router. Unfortunately, I can't get the AirPort setup to recognize the AirPort Express and the AE is just flashing amber. What the heck can I do here? I know all the necessary info: the SSID of the Linksys network, the AirPort ID of the AE, the MAC address of the router, etc.

I'm stuck.

Stephen:

Your setup is really no different from the one described by petemay in his detailed instructions. Have you tried following those instructions and if so, where do things seem to go wrong? Note carefully his instructions begin by telling you to (a) do a factory reset of the Airport Express and (b) temporarily run an ethernet cable between the Linksys router and the Airport Express. The actual manual configuration of the Airport Express is done using the Airport Admin Utility, and can be performed using either your Mac or your PC (the instructions are identical for both) but I recommend you use the Mac.

Feb 12, 2005 8:10 PM in response to petemay

I tried these instructions several times, including manually entering the XX information and everything seems fine until the very end. When I reconnect my AX (not very far even) the light never "goes Green." It stays flashing yellow.

Interestingly enough, my iTunes does notice something because the name I gave to the speakers appears in the iTunes pulldown menu, the "Connection to Salon (the name I gave the speakers)" shows, but doesn't make the connection.

Some other info, the Airport Admin Utility also seems unable to see the AX. Upon trying to connect to "traveller (the name given the AX)" it says it "was unable to read the configuration of the selected base station --An error occured".

some pertinent steps and info:

I did reset the AX setting as suggested, got the 4 green blinks.
I did connect the AX to the router with an ethernet cable.
The proper MAC address showed up in the Main Aiport window.
I've tried with and without WEP security enabled.
I've tried using DCHP and manual setup (using IP address 192.168.1.102)

And, when I click Update on the Airport Admin Utility, I can see that the AX turns green for a bit, indicating its receiving the changes, then goes yellow again. From there, I disconnected the ethernet, and then the AX and re-plugged it into a power cord only about 15 feet away.

I live in a very old Victorian, so I don't get much range from Linksys which is part of why I really want to get this to work. Just going two rooms away I can lose my signal from the Linksys.

If anyone has any suggestions at all, I'd appreciate it. I've spent hours since I got the AX trying to make this happen. I was very hopeful about these directions and of course the folks at the local Apple store insist it can't work.

Thanks in advance
