Hello,
A lot of factors can cause routers to drop signals. There could be too much interference so your device keeps changing channels. Try changing your wireless settings from auto channel to one of the available channels in the list. You can get to the router config at http://192.168.1.1
If your devices stay connected to the wireless but the internet cuts out, it may be your ISP modem.
There might also be a firmware update for your device that fixes this issue as well.
The latest is version 1.0.04 build 7. Here is the link:Download

Hello, Looks like your Mac might have connected to some other unsecured wireless network in your neighborhood. First connect any computer directly to your modem and check if you are able to go online. If the "internet" light is not lit on the router then there is no way your Mac can access internet through the wireless signals of that router. If you do not have internet connection through your modem then contact your internet service provider. If you are able to go online through your modem then perform the following steps..
1) Disconnect the power from both modem and router wait for a minute and connect the power back for modem first and after ten seconds connect the power for your router. Now once all the lights are stable check if you are able to go online through the router. 2) If the above step didn't work then you will have to reset and reconfigure your router. You will see a small reset button at the back of the router, press and hold it for 10 seconds and let go of it( while power is connected to the router) now disconnect the power from your router and connect it back after 10 seconds. Once you have done this you can reconfigure using the disk provided with the router by re-entering the ISP information. 3) Once this is done check if you have any firmware update to your router by logging on to the router vendor's website and entering your product details.
Hope this helped..!

Try power cycling the router.
Disconnect the router from all computers. Power off the router. Power on the router. Reconnect the router to all computers. Check the Internet connectivity.

Make sure you can go online directly to the airtel broadband. If internet works fine, connect the D-Link router to the Beetle. That should be going to the Internet port or WAN port of the D-link. Then your PC to port 1. Try to power cycle both devices now. Unplug the power to the router first then to the modem. Wait for 30 seconds. Power on modem first, wait for the lights to go solid, then power on the router. Check if the internet works fine hardwired. If it is, wireless should work as well. Just connect to the signal coming from the D-link.

Did you buy it brand new?

before pluggin in the router make sure you turn off your computers and also power down the cable modem.

Then, turn all items with a minute delay from each other, in this order:

Cable Modem --> D-Link --> Computers.

Usually if it's a single port cable modem, it will lock a MAC Address (device master identification) and therefore when you try to connect something else, your Cable Modem is still looking for other device.
