Internet and modem light won't light up - Computers & Internet

They chain together. Connect the modem first to the ISP drop. Then the modem to the routers main port. Then the connect the PC to the router.

Modem > Router > PC

If you have a separate modem and router turn both off and reboot only modem till all lights up the reboot router till all lights up in that order sounds simple communication problem between router and modem. If router modem combo unit disconnect either dsl or cable from router/modem leave diconnected for a short time then reconnect and reboot till all lights up. Hope this helps.

u got the modem but need the adriver also to run the modem .so instal the modem driver from acer website

this is way too vague, try power cycling your modem and router. also make sure you have not accidentally hit the standby button (teal oval on front). let me know what lights are on and or flashing and what lights are not. that modem's GUI can be accessed by entering 192.168.100.1 in the browser bar and you may be able to diagnose your problem from there.

First step is to make sure if the modem is working. Connect your computer directly to modem with ethernet cable and see if you can log on to internet! if yes
next step connect modem to your router's WAN port with an ethernet cable and then connect your computer to one of the LAN ports of router with ethernet cable. Power down all devices and power up modem first wait until all lights are on and then router wait until all lights are on then your computer! 9 out of 10 times this works! try good luck!!

it is common for the network port to fail on the DCM425s. a couple of things to try...1. a new network cabe2. hold the reset for 30 seconds (small hole on the back)3. try using the usb connection (this will not allow for a router connection and XP should give you a genaric driver so that you can see if the modem is working other than the network port)
if all else fails, it would probably be easier to take the modem into the local office and ask for an exchange. trust me, i am a service tech for a cable company and it is a lot easier to take the modem in for an exchange than arguing with some one on the phone who has no clue how to trouble shoot a modem and then waiting for another incompetent tech (if he didn't check to verify that it was working he was incompetent) back out to screw it up again. also ask if they have any motorola modems... there more reliable.

first there should be 2 cables connected the device.
1) power adapter
2) ethernet cable from either a dsl modem or a cable modem connected to the wan connector
with most cable modem service its usually dhcp meaning you are always connected to the internet
with some there is ppoe connection where a user name and password is used to make a connection to be on the internet with the dsl modem
there are some dsl companies that are dhcp just like the cable modem companies.
with the ethernet cable connected the wan port on your router there should be some kind of activity light on the router but check with the type connection from your dsl or cable internet provider. also you will need a second ethernet cable to connect your computer to setup and configure the wireless settings and wep protection.
