Here are some of the problems commonly encountered when making an Internet connection with Window's 95/98 native networking.

Where do I make changes to my Internet
configurations?

Go to My Computer | Dial-Up Networking                                                    (or Start | Programs | Accessories | Dial-Up Networking).
Highlight the connection icon and go to File | Properties. 

Save password is greyed out. How can I fix it?

How do I disable call-waiting?

Double click on the Awesomenet icon and hit the Dial Properties button.  Check the box for This location has call waiting.                                          To disable it dial... and select *70, from the drop down box at the right.

How can I find/set the port speed?

Start | Settings | Control Panel | Modems | Properties | Maximum
Speed.

Or you can access it by highlighting your connection icon under

Dial-Up Networking and selecting File | Properties | Configure | General.

Where do I enter a new modem initialization string?

Go to My Computer | Dial-Up Networking, highlight the Awesomenet icon and select File | Properties | Configure | Connection | Advanced | Extra Settings. You do not have to enter the init string's AT prefix.

Where can I find the current IP address that's been assigned to my machine?

Hit the Start button and select Run, in the dialog box type in the command winipcfg.

I have to click on the dialer to open my connection but I'd prefer clicking on my browser. Is there a way to do that?

Go to the Dial-Up Networking folder and choose Connections from the menu bar and then Settings. Select Prompt to use Dial Up Networking. 

If that doesn't work, go to the Control Panel and double click on the Internet icon and select the Connection tab. Check the Connect to the Internet as needed box and select the Dial Up Networking connection.

I'm trying to make a change in the dialer setup but every time I click on the dialer in Dial-Up Networking, it dials.    How can I fix that?

Double click on My Computer | Dial-Up Networking. Select Connections from the menu bar and check the Prompt for information before dialing box.

I get a black box every time I log in. How do I get rid of it?

Go to My Computer | Dial-Up Networking, highlight the Awesomenet icon and select File | Properties | Configure | Options.
Uncheck the Bring up terminal window after dialing box. Hit OK.

Why am I getting the error "Dial Up Networking could not negotiate a compatible set of protocols.                            Check the Network settings in Control Panel and try again?"

Check the following:

Go to My Computer | Dial-Up Networking then highlight the connection icon. Select File | Properties | Server Type. You should only have TCP/IP check under Allowed Network Protocols.

Go to Control Panel | Network. You should have only one TCP/IP stack installed for the Dialup Adapter. If you have more than one, highlight the unneeded installations and click on Remove for each one. 

There is a Windows 95 bug that can cause the error. Go to My Computer | Dial-Up Networking then highlight the connection icon. Select File | Properties | Server Type. Uncheck Enable Software Compression. Next, go back to the connection Properties, select Configure | Connection | Advanced and uncheck Error Control. 

If problems persist you may need to remove and install the TCP/IP stack under Control Panel | Network. If that doesn't work, reinstall Dial-Up Networking through Add/Remove Programs. In both case, you will need to have your Windows 95 CD handy.

I'm getting the error "This DHCP client was unable to obtain an IP Network address from a DHCP server." How do I fix it?

Under the Control Panel, double click on the Network icon. Highlight Dial-Up Adapter, then click Properties. Click on the WINS Configuration tab at the top. Disable WINS Resolution should be checked.
