Connecting to Airport Express from a Router

Question

I have an Airport Express that works nicely with my 13"MacBook Pro. However, I still have my Dell PC, and a modem with only one ethernet out port. I assume I will need a router to use both the wired PC and to use my MacBook either wired or wireless with the Airport Express.
When I first bought the Airport Express, I brought it to a friend's house and plugged it into her older Linksys router. This did not produce any wireless internet connection. So I unplugged her Linksys, and plugged from her modem to my Express, and it worked fine.
So, if I need to buy a router to have both of my computers online, how can I be sure it won't just render the Airport Express useless as my friend's Linksys did? Are the newer routers better for this?

Answer 1

I'll have to consider if I want to keep adding Apple hardware to my collection and get an Extreme, or if I just want something cheap for now.
FYI ... your AX will support up to 10 wireless clients (computer, printers, etc.) simultaneously.
I can't wait to try this solution out with my friend's old Linksys and see what happens.
One nice feature of your AX is that it can store up to five different configuration profiles.
What this all means is that you can reconfigure (& save that configuration) for multiple locations, like "home," "school," "friends," etc.
You will need to use the AirPort Utility, located in Applications/Utilities to create & save these profiles.
To create a new profile:
o Open AirPort Utility, select your AX from the list, and then, click "Manual Setup."
o From the AirPort Utility menu, select "Base Station," and then "Manage Profiles."
o Click "+" to create a new profile; give it a name, and then, click OK.
o Set options, such as network name, passwords, Internet connection method, etc.
o When done setting the options, click Update.
To switch profiles:
o Open the AirPort Utility, select your AX from the list, and then, click "Manual Setup."
o From the AirPort Utility menu, select "Base Station," and then "Manage Profiles."
o Click on the desired profile, and then, click OK to apply the new profile and restart the AX.
Just remember to switch to the desired configuration profile before removing power from the AX.
