My hardwired computer gets on line but the other two wireless can't. I've reset the router several times but no luck. Checked all the connection still no luck.

To connect to your wireless router, the router's wirelesssettings needs to be configured with the SSID, encryption etc. and also thewireless cards in all the laptops/computers needs to be configured with theserouter's wireless settings. Then the laptops/desktop computers can communicatewith your wireless router.
Connect a LAN cable from the Linksys to the LAN port on your computer.
Open a browser and enter the Linksys configuration URL
http://192.168.1.1
The default login = admin
The default PW = admin
You can protect your router by changing the default admin PW (write it down andput it in a safe place)
Go to the wireless configuration and set up the SSID and WPA or WPA2encryption.
Now apply these settings to the wireless card in your laptop/computer.

OK... Have you checked the settings of the LAN card in your PC? It should either be set to DHCP or 192.168.1.2 for the IP address and 192.168.1.1 for the gateway.

Try resetting your router.

You could

1) Reset the router to factory default by hitting the reset on back

2) You could visit the router over the wireless link (http://192.168.1.1) default password is "admin" username blank.

Check on the page to ensure the ports are enabled.

3) Update the firmware on the device. see if it works.

Note there is a port called "uplink" which is designed for the internet connection and not the local computer.

Connect your laptop to your router with Ethernet cable and check you router should be mixed mode in router's setting area.

there maybe a few things you could try 1) see if there is a later firmware update for the router from the manufacturer 2) Loginto the router and remove any wireless encryption - see if that helps 3) It may be wireless interferance and the router is switching channels - download this program and install http://www.xirrus.com/library/wifitools.php Then have a look at the channels in use - loginto the router and change channel to one that isnot used - try and use channel 1 or 6 or 11 4) Remove the wireless profiles from your PC http://mgmcc.forumotion.net/networking-tutorials-f17/removing-an-existing-wireless-profile-t109.htm

For the WRT310n, back to the User Guide (download from Linksys), perform a reset and start over following setup instructions (make sure the router is hardwired to the laptop). Set up a new home network on the laptop using Control Panel. Make sure the adapter settings are correct and good to go. Then see if you can connect to the router with your browser to set it up. After setup, you should be able to connect to the router wirelessly from the laptop, but you have to make sure the wireless transmitter inside the laptop is turned on first (see the laptop user manual).

in your internet browser type the address

198.162.1.1

that will take you to the setup page for your router.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/sean_54c3a3dc48a7773c

You need to connect your computer hardwired to the router and reconfigure it. On your wireless computer, you need to delete all the preferred networks and add a new wireless profile.

Possible you did reset the router. Its okay to connect to that linksys network name. But if you want to customize you network name.

MAKE SURE TO USE THE WIRED COMPUTER TO SETUP WIRELESS CONNECTION.
Example : The Desktop computer that is connected to directly to router.


Just follow the steps.
