Might want to try a new ethernet cable going from your modem to your computer- If that does not fix your problem then I would try connecting through USB.

Won't connect to internest.


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.

Connection show as good but internet wont come up


Could be a multitude of things, I would check your proxies first.
Go to Tools > Internet Options > Connections > LAN settings.

You most likely are not using a proxy server. Ensure your settings mirror the above, especially the "Use a proxy server..." setting.

One other possability: When you say you can connect to the LAN or wireless connection fine, I must assume you are using a router with wireless capabilities.

Just becuase you can establish a connection to your router, does not mean that router has a gateway to the internet. The router is simply used to create a network for file, printer, and internet sharing. It is totally possible to use the router strictly for networking purposes and not for internet sharing.

That being said, I would ensure the cable/dsl modem is securely connected to the router. Also try power cycling both devices. Check the lights on the modem, typically they give a status. Mine has a POWER, ETHERNET, DSL, INTERNET, and ACTIVITY light. Green typically means status is functional, red means it is not.

When my ISP is down, the DSL light will be flashing red. It is time to call your ISPs tech support if that is the case. Check all your connections to be secure and power cycle everything first, your ISP will ask you to do this as soon as you call them, and it does resolve alot of problems quickly.

There is always the possibility of them having an outage.

General rule is always check the physical layer first, which is cabling and hardware. Make sure it's on and plugged in. Then try rebooting it all.


Hope this helps.

How to confirm that the BSNL modem is having problem & cannot be used any more if INET light is continuously blinking?


There are several lights on your modem/router. Each one has a function and signals whether it is working correctly by the color it is displaying and a few other factors.

All of the lights on your modem/router should be green and solid - EXCEPT for 2 which are for your internet and wireless services. Blinking means activity. If you INET light is continuously blinking that means its healthy. Blinking means activity. The internet always has activity. The blinking does not signal your activity - it signals the traffic and connection on the internet. Your wireless connection also has a light which should show activity and availability. A blinking light on your wireless connection means that either someone is connected wireless and using the internet or that the connection is up and available for wireless access.

All of your lights should be green. If you see a red or yellow light - regardless of whether it is flashing or not - it means that there is trouble or problems that need to be corrected.

Each light is marked with its function. They should say things like "power", "link", Internet or INET, and "wireless". When you turn on the modem/router during your first set up, let it power up and finish its testing before connecting your pc and turning it on. The modem will test each light, make them all go from red/yellow to green - then make them all turn solid green (not in that exact order) and this is all normal. You will know when it is done when all lights are solid green and stop blinking and/or moving (except the INET & wireless lights which will be constantly blinking). When all lights other then those two are green and steady - then its time to connect the cable to your pc and power it up.

If you are having problems with your internet connection - you can rule out the cause being your modem/router by following the instructions above. When you rule out that the modem/router is not the cause, you can continue by checking your PC.

For a wired connection (wired meaning that you are connecting your computer to the internet by using a cord/cable) the first thing you want to do is make sure that the computer is automatically sensing the connection.

Your computer should automatically sense that there is a live internet connection when you connect the ethernet cord from the modem/router to the pc. When its working right, the computer will display a connection picture which is called an "icon" on the bottom right side of your screen near the clock area. Sometimes there is a downward arrow by the clock which needs to be clicked on to expland this area and show all icons for running programs. If you see a downward pointing arrow by your clock on the bottom right side of your screen, click on the arrow.

Test that it is sensing the internet connection by unplugging the ethernet cable from your pc and watch the bottom right side of the screen at the same time. Unplug it and repeat if necessary while watching the bottom corner to see a change which indicates it senses the connection. A normal internet connection icon looks like the picture of a computer monitor. Some glow green when they are active and the ethernet cable is connected. Some show a red "X" over the picture of the monitor on the bottom right side of your screen when the internet connection is down or not working. Some will say "cable disconnected" when you unplug the ethernet cord. Some show "Cable now connected" when you plug it back in. You should see something change and/or appear if your pc is picking up the internet connection correctly. When you have verified this as true - then you can continue on to the next step of troubleshooting the internet connection.

DSL service is an internet connection that is always on. Its considered a "live" connection. DSL connections usually do not require any set up (programming or changing settings). The only time that this is not the case is when someone tries to to set up a dial up connection like aol over the top of a dsl connection. You can check this by going to your control panel, click on internet options, and choose the "connection" tab at the top. In the connection area box there should be "nothing". The connection area box is for dial up connection settings. If a dial up service was set up in the pc it would show it here (you would see AOL dial up ect). If you see a dial up connection set up and you know that you have dsl, click on the remove box and delete it from this area.

You do not need to install anything from a disk to establish an internet connection if you have a dsl line. That means you dont need an "aol" disk or software to make the internet work.

to start the internet click on the blue "e" on your desktop which stands for internet explorer.

If you have any questions you can reply to my solution by going into the problem you posted on Fixya and click on the "reply" option.

hi, rmoriconi
pay no attention to people that tells you that that switch turns your wireless on and off..you do not have a wireless modem

all it does is block your incoming and outgoing internet service, its a security feature and thats it

(your modem is not wireless, if it is, its the first wireless modem i have ever seen)...

When the DSL light turns red it indicates that the modem has no internet signal.
So please check if the cables are connected properly
Also ensure that there is a proper signal to your premises without any interference
This is called intermittent connection
If the DSL light turns red it indicates that there is a problem with the cables connected or the DSL line
Please check your DSL connection with ISP

There is on another reason that the modem might have gone bad.
If all the above steps are executed and if this issue still persists replace the modem

PC/Activity light


Make sure the Ethernet cable going from the modem to the computer is secure. Then go to your computers control panel and clock network connections. Look in LAN, any try to find your connection. If it isnt there , than you will need to call your ISP, and they will install it all correctly for you at no charge.
