I had forgotten my password so i held in the rest button and it caused my network to not work. Ive tried everything i could find online about this situation.


Plug your computer directly into the Internet appliance (cable modem, DSL modem, etc.). Reboot. If using Windows, open a command prompt and type "ipconfig", without the quotes, then hit Enter. Look at the line for Gateway.

If it starts with 192.168, write down the whole number. If it starts with 10., write down the whole number. If it starts with any other number, you're done in here.

If the Gateway number started with 192.168 or a 10. (ie 192.168.1.254 or 10.1.10.1), disconnect your computer from the Internet appliance, then connect it to the router. Power up the router. Go back into the command window (Start, Run, CMD, Enter or click on Command Prompt in the Start Menu under Accessories). Do the ipconfig thing again, and look at the gateway. This is the IP address of the router, typically 192.168.1.1.

Open your browser (Internet Explorer, Firefox, etc.). In the address bar, type in the gateway address of the router, typically 192.168.1.1. If the IP address of the router was the same as that of the Internet appliance, change the last number to something different (if the modem and router were both 192.168.1.1, change the router to 192.168.1.2). Turn off DHCP on the router. Connect the router to the modem, plugging into of the numbered ports on the back of the router. All done.

If the IP address of the modem was something other than a 192.168 or 10 based number, simply plug the cable from the modem into the WAN port on the router, plug your computer into one of the numbered ports, then restart everything.

I am installing with my Sony VPCZ1 PC but cannot get past the first task which says my wireless adapter is still turned on when in fact it is turned off? I am running Windows7. Can you please help?


First;I think you need to use W7 to configure your connection with the router.
But try :
Use the PING command to test the communication between the computer and the gateway.

Goto Start > Run and enter COMMAND.
From the Command Prompt, enter PING 192.168.0.1.
The gateway should reply.

Verify that the residential gateway is getting power. With the broadband modem connected to the WAN port on the gateway, you should have a soild WAN link light. You should use the same cable that connected the modem to the PC to connect the modem to the WAN port on the gateway. Any port on the gateway that has a computer connected to it should have the corresponding LAN link light lit. If you do not get the appropriate link lights, try using different cables.

Minimum System Requirements• Cable or DSL Modem
• Computer with:
• Windows® Vista*, Windows® XP SP2*, or Windows® 2000 SP4*, or Mac OS® X (v10.4)**
• Internet Explorer v6 or Mozilla Firefox v1.5
• CD-ROM Drive
• Network Interface Card
• For Internet Access:
• Cable or DSL Modem
• Subscription with an Internet Service Provider (ISP)

I have a dell inspirion with vista and I can not connect to the internet using a cable modem.


Have you tried disabling your firewalls, f it came with norton 360 or norton internet security remove it and then try connecting if you can then its your firewall stopping it
another way to try without uninstalling is to click on the start button then in the search box type CMD and press return
in the command prompt that opens type
ping www.google.com and hit enter
if you get four packets sent and four received your firewall is blocking the internet connection. Remove it try the internet if it works reinstall it and it will detect the new network and allow you access.

type ipconfig in the command prompt window and hit enter if you get a 169.x,x,x x=any number then the laptop has no ip. Make sure that the network card isnt disabled
if they all fail and the laptop hasnt got an ip address, then the problem is the cable modem, is the internet active? I.e. you can plug it into another pc and it works

Cannot connect although plugged in


Check the ipaddress. Type ipconfig in command prompt. Then ping a website in command prompt if u get proper ip address e.g 10.132.147.121. Try to ping www.google.com in command prompt. If u are unable to connect. Tried to release renew Ip address.
Type ipconfig /release then ipconfig /renew in command prompt. If you are able to ping google and still unable to connect to website using internet explorer, then issue with browser or with OS.
