I have instaled the TRENDnet tew-430apb, but, if i connect my laptop to the AP, i get connected but no internet access

It can drop signal if there are other devices working in 2.4GHz band interfering with it. Try to switch over to 5GHz band.

You may be trying to connect through a G or B device to your N router. Verify that there are no serious obstructions or that the pc is not underneath something or enclosed. Metal near the pc can cause the signal to lose strength. Not having a wireless N card or adapter can also cause this.

Also if you are trying to connect through ethernet cable verify that windows is being assigned an automatic ip address, if it is static in windows change it to automatic.

You can get your external IP address by going here:

You can get your internal IP Address in Windows by:
1.) Click Start
2.) Click Run
3.) Type in CMD, hit ENTER
4.) Type in IPCONFIG at the command prompt, it will display all of your IP Address's.

same problem. the network shows up in the connection list, has max wifi signal, password was not rejected, and still the cursor/icon just spins indefinitely and never connects. I have Dell laptop with windows vista using the newest Verizon Fios router.

Connect your PC to the router with a cable to one of the LAN connections - Now you need to Log into the setup of the router - to do that open a web browser, use Internet explorer (some routers setup pages do not work correctly with other browsers) In the browser address bar - Enter IP address http://192.168.1.100 to the address location. When there is a screen needs to enter the User name and Password, both of the default Username and Password is “admin”
Now you can goto the wireless section or secruity section and set the type of encyption to WEP, WPA, WPA-PSK etc and then make up your own password. See Page 12 of the User Manual
On the PC Double click on the wireless connection in the system tray (bottom right hand side of screen) and then connect manually to your wireless signal - you will be asked for the password you set in the router.
Now you are connected.

Thanks.

I had a TEW-421 card for a time, and it can not do WPA encryption, only WEP. It's not a driver shortcoming, it's the hardware in the TEW-421 card.

Sorry to tell you it's a dead-end, but at least now you know.

clear your browser cache, close, relaunch your browser and try again
You probably cant access it because you are not authorized. If its locked on your rooftop then your ISP should configure your access and that you're not authorized.

if you press the reset button at the back holding it in for about 10 seconds, that should set it back to it's default. Then in your address bar log back into it. The default username is usually admin and sometimes the password is admin too. If not it's either password or there is no password so you can just press enter on your keyboard. This way you can set it up the way you want to. Just be aware that if you use WEP 128 bit, you have to have 26 characters as a password. If you use WPA PSK then you only need 8 characters. You should be able to access this from the word wireless in your options list. I would run the setup again first and then do all the configuration next. Lets hope this helps you out.
