When I power up my modem, home network and machines, sometimes the machines don't connect to the internet. Why would this be happening? Is there anything I can do to intervene?

(See my setup below)

The order I usually choose for power up is:

  1. Switch on Modem and Bridge1 (both on same extension power block sockets). Modem boots
  2. Not waiting for modem to finish booting (all 5 lights green) I switch on Bridge2
  3. And straight after that I power up all three machines
  4. Once All powered up I then can see if they are on the internet or not (if not, the yellow warning hazard triangle symbol shows over the connection symbol)
  5. Then I may power up my NAS (which I think is irrelevant in this problem but included for completeness).

Details on hardware:

  • Bridges are a 4 port Zyxel 1Gb ethernet
  • Modem is Thompson speedtouch 580 ADSL with 4 x 100Mb/s ports and WiFi. Occasionally I have a HTC Desire Z phone and iPod touch connect to it, also a Revo Pico Radiostation internet radio. (But I feel their roles are irrelevant in this problem, here for completeness)

Update 2

Added printer, again for completeness, don't think it causes the issue.

With incomplete information I'd put my money on a DHCP issue. Turn the Modem and two bridges on and let the modem finish booting before turning anything else on. (The DHCP server not being available during a reboot should not be an issue for Windows 7 so it's probably an issue with the modem/router).
