Your computer operating system makes the network choice. If you're using windows, look in the lower right-hand corner and you should see signal-strength bars like on your cell phone. Click on those bars and you should see a list of available wireless networks. Click on the network for your uverse router and choose "Disconnect." Then click on the network for your hotspot and choose "Connect." Then your computer should connect to your hotspot.

Check you have your cable modem plugged in to the WAN port, not the LAN port on the router.

If it is still a problem consult your ISP about the set up.

Enable the Wireless Zero Configuration service so it starts up automatically, go to the Start button. Select the Settings option and then select Control Panel. If you are using the Windows XP view, select the Performance and Maintenance category and then select Administrative Tools. If you are using the Classic View, then select Administrative Tools. Click the Services icon in the left pane. Click the Wireless Zero Configuration icon in the right pane and change the Startup Type dropbox to Automatic. This setting will set the service to start automatically at boot time. Then click the Start button to start the Wireless Zero Wireless Zero Configuration service and click the OK button.

NO!

my wireless router does its a netgear 71

the router may not be designed for that regian you may need to purchase a new router

Never buy Netgear. They design product so it won't work unless you pay more for technical support. They told me the technicians during the 90 day warranty are not good enough to fix problems, so you can't get solution until warranty runs out and you have to pay extra!

Check with the Settings on Router
Since u have a Dual band Router, Check which is Enabled
make Sure u have the N Network Enabled or Not......

Check and All the Best...........

Dual band means it is working on both 2.4Ghz and 5Ghz frequency. If your computer can connect on both frequency that only means that the wireless adapter in your computer is also dual band.
