Configuring WDS w/ Airport Extreme Dual-Band 802.11n & Express 802.11g

Question

I currently have an Airport Extreme Dual-Band 802.11n Model: A1301 (located downstairs) and an older Airport Express 802.11g Model: A1084 (located upstairs) which I had been using to stream iTunes to my upstairs stereo (which worked flawlessly). Recently a friend of mine recommended that I reconfigure my network to a Wireless Distribution System setup which would allow me to create a remote wireless node which improves my wireless signal strength upstairs, allows an interface to Airplay to play our music from our iPod's/Pad's and also provides an hard-wired Ethernet connection for my newly delivered Network Extender for my cell phone. So I followed the URL: support.apple.com/kb/HT4262 to assist in this conversion and found that I was unable to configure my network as desired. While this documentation is very good, there is one snafu that I worked out that finally allowed a successful setup. Follow the instructions for:
- Connecting a WDS main base station to the Internet
- Configuring a WDS main base station
- Configuring a WDS remote base station (See last line of instructions for the correct WDS Main ID)
Ensure all Wi-Fi base stations are powered on and allow them time to appear in the AirPort Menu Extra.
From the AirPort Menu Extra, select an 802.11g Wi-Fi base station to configure as a WDS remote.
In AirPort Utility, select the WDS remote Wi-Fi base station in the Base Station Chooser, and click Manual Setup.
Select the AirPort icon from the Toolbar, and click on the Wireless tab.
From Wireless Mode select Participate in a WDS network.
Click on the WDS tab.
From WDS Mode, select WDS remote.
Enable Allow wireless clients (see the first note below).
If not already supplied, enter the 2.4Ghz AirPort ID of the WDS main, then click Update.
There are two Apple ID's for the dual-band Extreme (2.4 & 5.0Ghz). Be sure to use the 2.4Ghz ID which is listed under the "Summary Tab" of the utility. What is confusing is that in the AirPort Utility, when you position the mouse cursor over the graphic of the Extreme on the left-hand side of the GUI, you are presented with a yellow dialog box which displays the 5Ghz ID and this can be misleading especially when you are trying to connect to an older 2.4Ghz Express ...

Answer 1

My Express is the A1264 802.11n model. My Extreme is the A1354 model.
The most crucial issue is the the Tivo, because the Premiere only works with Ethernet (I dont' have and wont' buy the upgraded wireless doohickey), but of course I would prefer that the Express also act to extend the signal, and I particularly want it do so using WEP access (or nothing, see below), since I have a second Tivo which ONLY works wirelessly and which ONLY works using WEP, not WPA.
Since there were so many different issues and needs going on, I was excited about the Dual Band because it meant I could potentially get 5G speeds for my iPad and perhaps the Tivo Premiere connection, while allowing a completely separate band for the OLD Tivo.
The other option I've been trying out (to accommodate the Tivo2 that can't handle WEP) is having no security, but making the networks hidden.
A third option I tried to make work was to create a "guest network" for just the Tivo2.
But what I'm finding out (it's what I always struggle with...networking is a nightmare.) is that if you take one from Column A, Column B disappears, so to speak.
The way it used to work on the non-dual band Extreme was as I mapped above, and the Tivo2 and my iPad used the wireless signal with no problem while the Express was Ethernet connected to the TivoPremiere, but it did so using WDS, which doesn't even seem to exist as a possibility, forget teh fact that it undermines the speed boost (so I read)
I've frankly never been able to understand the differences between the various modes and structures, and believe it or not I'm very smart and very comfortable with computers and Macs, having worked on them for 25 years.
And one of the biggest reasons I've had such a hard time is because of the many times that I have updated after making changes, Airport Utility tells me it worked, but nothing happens and then after too much frustration I end up unplugging and shutting down every single piece of equipment and rebooting everything and then it DOES work. Sometimes. But I can't be doing that every time I make one tweak, I'll go insane!
And the number of pin-resets I've done on the Express, the Dual band, and even the cable modem would make your head spin!
So there's my story. Kinda. Does it make any sense? At least in terms of my goals?
Your help is more appreciated than you can imagine.
