Unable to connect to internet

Have you set the TP Link TL-WA901ND IP to have 192.168.1.1 as the default gateway ?
Also DHCP server is where ?
IN the TP LINK TL-WA901ND or in DLINK DIR 615
Only have one Router running DHCP and set the default gateway in the leases as 192.168.1.1.
What subnet mask are you using is it the same through out all devices ?

Welcome to FixYa! In regards to your problem there are possible options you could follow. 1. Check first if your computer is detecting the router. Go to your Network Connections and see if its detecting a connection with the D-Link router that you have. 2. I suggest go to this site that has a manual for setting up a D-Link DIR-300 Wireless Router.Check if you missed any of the process. Steps: Go to Google.com then type "cant get a internet Problem with the D-Link DIR-300 Wireless Router" and then look for DIR 300 Wireless Router Manual. There you will find all that you need in setting up your router. Hope this helps! Thank you for using FixYa!

this can normally be fixed by restarting the router

Click the link above it will help you if you want to make it a repeater.

This issue is possibly due to a configuration problem
1.Log into router
2. Verify wireless router name( on the computer) >>> ( on/off)
3.Note router name you are connecting to.
4.. Check the laptop do ipconfig /all to see current IP addresses.
5. Set the laptop up in the router by WEP KEY or MAC address.
6.Note router name you are connecting to.
7. Move the laptop about 20ft away and try to log on to the internet.
This is for all routers to set up wirelessly.

Here is the link for the DIR-330 your model number did not list:

Ensure that the router firewall is not blocking the http port 80.

Have you configured the router to open your utorrent port?

Have you set up specific strict rules?

you need to open internet explorer while you are connected to the router.

then type in the address bar

192.168.0.1 and press enter.. it will ask you for the ::
Default Username: Admin
Default Password: ( leave blank )

Then click on the setting for wireless security, choose a security type wep, or wpa, and create a password..

then save the password, and exit internet explorer,

now you will have to reconnect to the router, and it will ask you for the new password.. Now you network is secure and no one can log on unless they have the password.

First connect your router to computer with ethernet cable.
Then you can access it with following link
http://192.168.1.1
or
http://192.168.0.1
type user as "admin" and password as "admin" or blank or "password"
then go to wi fi security set your WEP code it is your password to connect wi fi network.

Let me know if you need more assistanse.
Thanks

Yes, you can reset the password on your D-Link DIR-300 router. To do this, follow these general steps:

Access Router Settings:

Connect your computer to the router either via a wired or wireless connection.
Launch a web browser and input the IP address of the router (frequently 192.168.0.1 or 192.168.1.1) into the browser's address bar.

Login:

Enter the router's username and password. The default credentials are often admin/admin.

Navigate to Password Settings:

Look for the "Setup," "Wireless," or "Security" tab in the router settings.
Find the section related to changing or resetting the password.

Reset Password:

Follow the on-screen instructions to reset the password.
You may be asked to enter the old password before creating a new one.

Save Changes:

Save the changes and reboot the router if required.
Please note that the exact steps may vary slightly based on the router model and firmware version.
