I assume you are using Internet Explorer or Google under WINDOWS.

To change your homepage in Windows, click open your INTERNET OPTIONS icon in the CONTROL PANEL. It should open a window under the GENERAL tab. There you will see a HOME PAGE section where you can erase (delete) whatever is there, and type in the URL of the homepage you desire - like http://www.google.com/.

If you want to open up your session with more than one TAB, just enter each URL for each TAB in the browser on a separate line in this HOMEPAGE section.

That more than likely mean you have put the password in wrong or you are using the wrong authentication type.

For Windows XP below:
Click Start/Control Panel/Network Connections then Right Click on the WirelessNetwork Connection and select Properties. When the Properties window openclick the Wireless Networks tab. Click on the SSID for your wirelessnetwork that you connect to and the Properties window will open. You canchange the Authentication Type to match the type set in your wireless routerand you can also change your password or Network Key to make sure you have itin correctly.

For Windows Vista below:
Click Start/Control Panel/Network and Sharing Center then look to the left ofthe open window and click Manage Wireless Networks. Find the SSID of thenetwork that you connect to and double click it. When the window opensclick the Security tab to change the Security Type (which is theAuthentication), The Encryption Type and the Network Security Key (which is thepassword).

For Windows 7 below:
Click Start/Control Panel/Network and Internet/Network and Sharing Center thenlook to the left and select Manage Wireless Networks. Find the SSID of thenetwork that you connect to and double click it. When the window opensclick the Security tab to change the Security Type (which is theAuthentication), The Encryption Type and the Network Security Key (which is thepassword).

Why not, what type of message are you getting?

Let's start with Internet Options. If you have Windows XP Click Start/Control Panel/Internet Options. If you have Windows Vista or Windows 7 click Start/Control Panel/Network and Internet/Internet Options.

When the Internet Options window opens on the General Tab make sure you have a valid web address as the Home Page. If not, create a simple Home Page by typing: http://www.google.com You don't have to click OK now because if you do the Internet Options window will close.

Click the Security Tab and under where it says "select a zone to view or change settings" Click on the one that says Internet, then scroll down to near the bottom right and make sure that DEFAULT is grayed out (whereas you cannot click on it). You can Click on Default just to be sure. Next click the Intranet so that it is highlighted and make sure DEFAULT is grayed out so that you cannot click on it. Do the same thing for the other two zones (Trusted Sites and Restricted Sites). After all zones under the Security Tab are set to Default click the next Tab which is the Privacy tab.

On the Privacy Tab you want to make sure that DEFAULT is grayed out, if not click on it. When in doubt just click the Default tab.

Next skip over the Content tab and proceed to click the Connections Tab. On the Connections Tab make sure that the Never Dial A Connection is checked if you have something in the white box above it in for Dialup and Virtual Private Networks settings. Look down on the right near the bottom and Click the LAN SETTINGS button. When Lan Settings open up the only box that should be checked is the very first box that says: Automatically Detect Settings. If any other box is checked remove the check from it or you will never be able to connect. Click OK to close the LAN SETTINGS tab.

Next skip over the Programs tab and click the Advanced tab. When it opens slide the blue bar on the right all the way down until you get to the bottom of the window. You want to be able to make sure that if you see something like (Use SSL 2.0, Use SSL 3.0, Use TSL 1.0) that you put a check in the box to the left of each one of them. Afterwards you can click OK to close the Internet Options Window.
