Weird. Some rhetorical questions:
1. The router may be on a seperate power strip, but what about the
DSL or cable modem? Is that being powered off?
2. Did you power cycle the router AFTER the owners machine was turned
off to see if it magically recovers with his machine still turned off?
3. Is the owners machine connected via wired or wireless? If wires,
run IPCONFIG on his Win7 box and see if you get the usual
192.168.1.xxx or if you get a routeable IP address. If routeable, he
has the CAT5 cables miswired in back of the router.
4. Check the firmware version:
Note that v1 is quite different from v2.
5. If a DSL modem on the evil AT&T, is the PPPoE login in the DSL
modem, in the router, or in the owners Win7 machine? I prefer to have
it in the router, but it's much easier in the modem. It should not be
in the Win 7 machine. If the owners machine starts with "click here
to connect to internet" it's time to reconfigure.
6. What do the lights do on the router and modem when the owner
powers off his machine? I think there's an "internet" light on the
router that checks for connectivity. What does it do?
Looking at the settings, there's nothing on the guest page that might
I would guess #1 as mostly likely.
