Virgin Superhub wireless connection to Airport Express?

The express is the only apple router that can do wireless bridging.. you cannot extend wireless after the bridge but it will provide ethernet connection.

Speed will be hampered by the wireless link of course.. strongly recommend wire or even Homeplug.. EOP type adapters as far more solid than wireless bridges... especially between dissimilar devices.. wireless links can prove slower in practice than you might expect.

The superhub would have to be in router mode.. the AE will be in Join wireless network mode so cannot be a router.

Your picture btw is not visible.. it will be on your computer but not to anyone else.

Yes, I can see the picture now.

In the picture the link between the express and the modem is wired.. this is what you are going to miss out on.

EOP adapters do not require you to hard wire.. it is using your electrical wiring for network.

Please read up about them as they do work well and very popular in places like UK.. where people run into difficult wiring situations with solid brick old terrace house styles.

If you use wireless.. my motto is try it.. you will be able to make the bridge.. that much at least will work.

From ethernet to the computer you should be able to run airplay over the speakers as long as you use hard wire connection and not wireless. You cannot extend wireless.. that is the point.

If you want to extend wireless you need two apple routers.. one upstairs and another plugged into the superhub downstairs.. Apple can only extend wireless to another apple router..

But you don't have to use a brand new express.. look on ebay for a second hand extreme.. last model Gen5 can sell here for around $80. That is cheaper than the Express and a lot better speed and wireless ability.

If this installation is possible and I follow the setup diagram, can you confirm that I can simultaneously have internet from the AE via ethernet to my MacBook (the diagram shows wireless, but i'd rather have an ethernet direct link), plus Airplay from my MacBook to the AE + audio line out, plus a signal from the AE to an Apple TV unit, plus WiFi to an iPhone? Can all four work simultaneously?

Yes, that should work. I have not done it.. so I am not sure how hard it will be.. but the basics of the setup is simple.

Using wired instead of wireless is not a problem.

The superhub is probably better as the main router..

Keep the Express in bridge mode.. and then you can use both for your network. If you bridge the superhub.. if that is even possible, you greatly reduce the options as the express has so few ports.
