What wireless router am I on?

You could plug another router into the ethernet port on the AE and use it as an extender.

That won't work either, if the AE is in client mode, as the Ethernet port is not usable:

In client mode AirPort Express does not offer itself as a wireless access point or use its Ethernet port. As a wireless client, AirPort Express is simply a destination for AirTunes and print jobs.
