I have here 2 wireless networks with a linksys wrtg54 access points. Each network has its own dsl line. Is it possible to connect to the networks simultaneously? I want to be able to access all the computers on network1 (192.168.1.1) and network2 (192.168.2.1) Do I need 2 WLAN network cards in my computer? (Windows 7) Is it also possible to use the 2 dsl lines in the same time for example to speed up some big file downloads?
