I have a Macbook Pro and use Time Machine for wireless backups, printing,etc. I also have a wireless USB modem for internet access as described in MacMost Now 133. The problem I have is that if Airport is on and connected to Time Machine, I cannot use the wireless USB modem. I cannot get a signal with Airport on. If I switch Airport off, I get internet connection with no problem but cannot use the two together.
