Means you have no internet connection. Try a new LAN cable between you router and internet modem. Connect directly to you internet modem make certain it is working. Reboot both devices.

The final solution is a factory reset of your router. You can do a factory reset by logging into the router using you browser. Go to the settings and perform a factory reset

If you forgot the router password, you ill have to do a factory reset by locating a small hold on the back of the router and insert the tip of of paper clip for about 10 seconds while the power is on. The router will be reset to out of box status and then you can set-up form scratch.

What happen when a adsl line work with a phone but not with a router

The phone line does two jobs. Voice phone which is what it was originally used for and ADSL modem which works at a high audio frequency.
Somewhere between the phone socket and the modem should be a filter splitter. One part goes to the phone and the other to the router. Make sure you have that.
The modem will have a power light and several additional lights. Assuming the power light is on we are interested in two of them; The ADSL light and the Internet light. When you switch the modem on you should first see the power light flash then go solid. Then the ADSL light will flash and then this should go solid. If this light does not come on then you have not plugged the phone wire in properly. If this light just keeps flashing slowly then the modem can't see an ADSL signal on the phone line. If you have a spare router you could try it and see if the ADSL light goes solid on that.
If the ADSL light is fine then the modem has locked onto the signal on the phone line, sync'ed. If not then this is the problem you must solve. Ask your ISP if service is set on your line.
The next light is the Internet light, this maybe a symbol like an i or a world. This light will begin flashing then go solid. It will flash with Internet traffic. This means you have Internet, as far as the modem is concerned. If this light does not stay on then your ADSL account name and password maybe wrong. You can correct this but that's a different question you need to ask.

Wireless light flashes & can't connect

This post is dedicated to describing the process of fixing an orange light on a Belkin router. But, first, it's important to know about the reason for the orange light. The orange light on the brilliantly-designed Belkin router provides an indication that either the particular connection had not been developed or the router is not capable of detecting the Internet. It might be due to the defected router, unplugged modem, and so forth.

A problem has occurred when trying to access the internet. Please check your DSL/Cable connection and verify your internet connection settings. Wtf is this ? Firmware update doesnt helped. .

Cables connection might loosen up. Check cables that runs from the wall jack going into your modem, make sure all cables are tightly plugged in. Also, check indicator light on your device. If DSL light is RED, OFF, flashing red, flashing green. there might be trouble with your Internet provider. DSL light indicator MUST be always on STEADY GREEN. If you see that the DSL light is not on STEADY GREEN status call your Internet service provider.

My at&t 2wire router dsl and internet light flash red often every 1 to 5 min

Hello, there could be a few things causing this problem. The router could be defective, or just died or you may not be getting enough power over your line from ATT. I would call ATT and ask them to test your line and see if everything is working properly. If it is, then you need to replace your modem/router. Any Dsl Modem and Wireless router will work.

Thanks for using FixYa!
