Creating a seamless wireless network with 2 AExpress units

Question

I have 2 Airport Express units in different parts of my house. I have struggled for YEARS trying to get them to create one seamless wireless network with the same name that I could float between. I have never been able to get that to work. anyone?
I know that some of the problems MAY have to do with the non-apple router settings, but I just have never gotten a clear response form anyone about weather it is doable, and/or worth doing. I would settle for 2 seperate wireless networks that didn't compete with each other and/or constantly need re-booting to stay active. I am generally the most tech savvy person I know and am consulted on IT by friends and colleageus regularly, but I just cannot figure this one out..
I am totally capable of setting this up, both in the router and the AE units, if someone can just tell me that;
1) yes it is possible and it will work, and
2) just set it up like this...

Answer 1

Thanks for the clarification.  Check your AirPort Express devices one at a time, but other than different device names to avoid confusion.....AirPort Express 1, AirPort Express 2....for example, the settings should look this:
Open AirPort Utility , select one AirPort Express, click Manual Setup
Click the Wireless tab below th row of icons
Wireless Mode = Create a wireless network
Wireless Network Name = Your choice
No check mark needed next to "Allow this network to be extended"
Radio Mode = 802.11n (802.11 b/g compatible) a good choice, but you can choose other combinations by holding down the option key on your Mac while you click on the selection box
Channel = Automatic
Wireless Security = WPA2 Personal an excellent choice if all of your devices are compatible with this setting
Wireless Password = Your wireless password
Confirm Password
Click the Internet icon
Connect Using = Ethernet
Connection Sharing = Off (Bridge Mode)
Update to save settings
Configure AirPort Express 2 exactly the same way and Update to save settings
Then, power down the entire network.....all devices....order is not important
Wait a moment, then start the modem/router first and let it run 2-3 minutes by itself
Start each AirPort Express the same way
Start each other network device one at a time about a minute apart
Check for proper network operation
IF....you did not have your AirPort Express devices in Bridge Mode before.....that is the reason why you are having issues now and also is the reason why the "roaming" network was not working.....assuming that there was a reasonable overlap in wireless coverage between the 2 Express devices, of course.
If you want to try the "roaming" setup again, assign the exact same wireless network name, security and password to both Express devices and confirm again that both are setup in Bridge Mode as the very last step before  you click the Update button in AirPort Utility.
Power down the entire network and start up in sequence as well as in the example above.
