Wireless network gets disconnected

the blue socket should be connected to your modem, it is this modem that supplies the internet for your router to distribute to your computers so if you disconnect the blue cable from your router you are disconnecting the internet

carry out the resetting of the dlink router
then use lan cable to gain access to dlink router,
set up the internet conenction (i.e. your internet provider modem plugged into the dlink router also)

if it has a built in wizard then just follow the on screen instructions

you will need to define SSID (wireless network name) and passkey (password for the wireless connection)

and the your done. disconnect the laptop from wired connection and connect via wireless

I assme you have a DSL or cable modem from Comcast and this is connected to the wall. The LAN cable from this modem should now be connected to the WAN/Internet port on the DLink wireless router.

If you want to RECEIVE telephone-calls:

COMCAST ADSL/CABLE modem <---> VONAGE <---> wireless-router

Turn each piece off.
Turn on the COMCAST modem, and wait for its lamps to settle-down to a "steady" pattern.
Turn on the VONAGE router, and wait for its lamps to settle-down to a "steady" pattern.
Turn on the D-link router, and wait for its lamps to settle-down to a "steady" pattern.
Restart the computer that is connected to the D-link router,
and you should have Internet access.

Sorry but that seems to be a pretty convoluted explanation. Here is how it should go.
Vonage unit connected to phone line(s) and cable modem. Linksys connected to Vonage box. Computers connected to Linksys.
Ethernet has a length limitation of about 300 feet before you need another switch (hub) or a repeater. Does your wire length exceed this?

check wther your wireless in on and even check that on router mac filtering is on,problm mite b your laptop is not getting detected by your router,jus check wther both are on,

With choppy audio and one-way audio, either party on the call hears the audio breaking up, or no audio at all. Dropped audio is when a call is in session and both parties are unable to hear each other.

• From your Vonage account, there is a feature called the bandwidth saver. This feature controls the amount of bandwidth used for a phone call. Try adjusting the bandwidth saver to either medium or normal. After you adjust your settings, test and see if there is a difference in the audio quality. Please note that when you change bandwidth saver it could take a few minutes for the device to reboot and take the changes. From your Vonage account, there is a feature called the bandwidth saver.

• Ensure that your Vonage device is at least four feet away from any other device.
• Ensure your Vonage device is in a well ventilated area to keep from overheating.
• Ensure no file sharing, P2P applications, or large downloads are running while you are using the phone. These activities can use up most of your bandwidth, leaving little left for your calls.
• Connect your Vonage device directly to your cable / DSL modem, if it is not already. If this helps the audio quality, then the problem is occurring between the Vonage device and modem.
• If your Vonage device connects to another router and not directly to your cable / DSL modem, try disabling any firewalls or SPI (Stateful Packet Inspection) on that router. Click here to learn about firewalls and SPI.
• If you wish not to disable your firewall, then you can port forward the Vonage traffic to the adapter. Click here to learn about port forwarding.

Wireless Routers and Cordless phones — If you have a wireless router and a cordless phone:
