This isnt an IE problem - it is IP based. luckily Windows NT and derivatives
do handle IP routing and /or multi interface config.
So - assuming that you dont have security / firewalls / restrictions on each
PC that get in the way...
what you have to do is get the PC to make sensible decisions about which
interface to use for which destination subnets.
if you run "netstat -r" at a command line prompt you will see the local PC
routing table.
here is part of one for my w2k PC with only 1 LAN connected - XP should show
the same kind of display.
================================================== =========================
Active Routes:
Network Destination Netmask Gateway Interface Metric
0.0.0.0 0.0.0.0 192.168.0.1 192.168.0.25 1
127.0.0.0 255.0.0.0 127.0.0.1 127.0.0.1 1
192.168.0.0 255.255.255.0 192.168.0.25 192.168.0.25 1
192.168.0.25 255.255.255.255 127.0.0.1 127.0.0.1 1
192.168.0.255 255.255.255.255 192.168.0.25 192.168.0.25 1
224.0.0.0 224.0.0.0 192.168.0.25 192.168.0.25 1
255.255.255.255 255.255.255.255 192.168.0.25 192.168.0.25 1
Default Gateway: 192.168.0.1
================================================== =========================
192.168.0.0 255.255.255.0 192.168.0.25 192.168.0.25 1
is the entry for the subnet connected to the Ethernet - you should have
entries in for both the local LAN interfaces.
the default gateway tells you which "way" the PC will send packets to
addresses not covered by the routing table.
if this doesnt work, then it probably means your local and corporate
networks have multiple subnets and you are going to have to add static
routes to override the default gateway setting for some destinations.
exactly what to set is going to depend on the subnets used - and may well
change if "corporate" alter the network design.
so you will end up with a complex set of config on each PC (and some PCs may
not allow you to set this up - eg older versions of Windoze).

i suspect the overall network is more complicated, and this will be tedious
to fully set up, and more difficult to test and maintain.
So - you can do this, but it is going to cause some ongoing hassle.
i suggest you "fix" this properly, forget about the separate wireless
network and get a local Internet feed integrated with the router that feeds
the corporate WAN.
After all - faster Internet is the reason you said you were doing this, and
hooking it into the common internal network fixes it for visitors with
laptops and so on, as well as local based PC users.
Also - you corporate network guys will then be able to sort out your
firewall, maintain the kit, get the internet feed fixed when it breaks, and
respond to any intrusion attempts.
