The devil is in the details they say... You didn't say how things were
hooked up?
Also since you say you have a problem that just started on 2 desktops, are
there other desktops connected that do not have a problem? It sounds like
you are saying that you have Cable Modem Internet, and maybe even that you
have another router connected to the actual cable modem box.
Cable Modem > Router > At least 2 desktops. How does that sound?
1.) If you in fact only have 2 desktops, and there are no other computers
that are getting Internet access, then try isolating things a bit. Can you
connect just one desktop to the cable modem directly, power cycle the cable
modem, and get Internet access (after the cable modem "acquires" and gets
all its lights) ?
If this fails, call Cable ISP support and have it troubleshot/fixed.
2.) Cable Modem passes DHCP from your ISP over the Cable modem to the 1st
connected thing. Typically it only assigns 1 IP Address and it marries that
assignment to the MAC address of 1st thing connected to it. This is why if
you switch the 1st thing connected to cable modem you must power cycle it to
clear that MAC address memory.
If #1 here worked ok, can you now connect the router to the cable modem with
the power *not* connected? Power cycle the cable modem and wait for
"acquired" lights. Connect power to router. Can you now go to the web page
of the router and check "Status" and see if it has obtained a valid IP
Address from the cable modem/cable company?
3.) If you were able to do #2, can you check IP settings, Gateway, DNS
settings on the Desktop PC that you are using? These should be assigned by
your router. This is also DHCP. This is a setting in your routers
configuration page. The enabling and range of DHCP is usually (if somewhat)
configurable.
I assume your router has about 4 switch-hub ports... you are plugging
Desktop PCs into those ports. And this stage you should now have Internet on
one Desktop PC?
4.) Next PC connect it and check the same things. If you are getting
169.254.x.x as an IP Address then DHCP is NOT working.
* How are we doing so far?
