Auto-Connect at Bootup

 
1 Drag and drop the EnterNet 100 Profile onto the Desktop to create a shortcut.
2 Drag this shortcut into the Startup folder.
   (If you drag the Profile directly to the Startup folder, the shortcut will be placed on the Desktop anyway).
3 Do a search for "enternet.ini" and open it in Notepad.
4 Change the line "AutoConnect=0" to "AutoConnect=1".
5 Save changes and reboot.
 

Auto-Launch Browser at Connect

 
1 Do a search for "enternet.ini" and open it in Notepad.
2 Change the line "LinkToSiteOnConnect=0" to "LinkToSiteOnConnect=1"
3 Add a website to the "URL=" line   (ie: URL=http://start.mindspring.net)
4 Save changes and exit.
 

Auto-Connect when opening a Browser or Email application

 
As an alternative to auto-connecting at bootup, which maintains an "always on" connection, the Auto-Dial (Dial-on-Demand) option may be used to automatically connect when opening an Internet aware application such as a browser or email program. This will function the same as having DUN automatically dial up when opening one of these programs, and the connection will terminate when the application that initiated the connection is closed.

EnterNet Dial-on-Demand requires that Dial-Up Networking v1.2c or later be installed. Windows 98/98SE and Windows 2000 ship with a version of DUN that is compatible with EnterNet Dial-on-Demand. Windows 95 and older versions of Windows NT 4 may have versions of MS DUN that are not compatible with EnterNet Dial-on-Demand.
The latest version of DUN (v1.30) may be downloaded here.
In addition to having DUN installed, a regular analog type modem or Virtual Private Networking (VPN) must also be installed for EnterNet 100 to automatically create the Autodial connectoid during the program installation.

Using the Autodial connection:
This dummy connectoid will never actually dial anything, it's simply a means to initiate a PPPoE connection.
1 Go to the Connections tab in Internet Options
2 Select the “Always dial my default connection” option.
3 Make Autodial the default connection and click OK.
4 Restart the browser.

Problem:
Correct DUN and a modem are installed but Autodial did not get created or it was deleted.
Fix: Create a dummy connectoid that's associated with the installed modem.
1 In Dial-Up Networking, double-click Make New Connection.
   (or in Internet Options - Connections tab, click on Add)
2 Name the connection Autodial, select the installed modem from the list and click Next.
3 Leave the area code blank and use 2.2.2.2 for the phone number. Click Next and click Finish

Problem:
Correct DUN but no modem is installed and Autodial is not listed.
Fix: Install VPN and create a dummy connectoid that's associated with VPN.
1 In Dial-Up Networking, double-click Make New Connection.
   (or in Internet Options - Connections tab, click on Add)
2 Name the connection Autodial.
3 Under "Select a device" where the modem is normally listed, choose Microsoft VPN Adapter. Click Next.
4 It will prompt for a Host name or IP Address. Enter 129.129.129.129. Click Next and click Finish.
 

Optimizing the MTU and RcvWindow Settings

 
First a note: The default settings usually work just fine. You can walk a customer through these changes if the customer is technically savvy, already has good throughput, and is just looking to improve it a bit. You can also walk a customer through this if they have been tweaking it on their own and have made their throughput worse as a result. If the customer has poor throughput and has never made any registry changes, then tweaking these settings is usually a waste of time and effort. Escalate it to Tier II as there is a problem with their line. Please insure that the cache has been cleared before escalating. Some customers have cache settings in the hundreds of megabytes, which will slow even a DSL or Cable modem to a crawl. Set the cache to 10 megabytes and empty it. Hardcoding an IP and Subnet into the TCP/IP settings of the NIC has been shown to improve throughput in some cases. The correct IP's and Subnets are listed on the router pages. If a customer wants or needs to return to the default settings, just delete these keys and reboot.

-----------------------------------------------------------------------------------------------
WINDOWS 95/98
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\NetTrans\0003
Add a String value and name it:  MaxMTU      then set the value to:  1454
or modify it to this.

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\MSTCP
Add a String value and name it:  DefaultRcvWindow      then set the value to:  65535
or modify it to this.

Adding or changing the DefaultTTL values is not necessary and will not increase the throughput.
If the customer already has one in there, either remove it or set it to 128.
(default TTL for Windows 9x is 64 and NT is 128)
Computer must be rebooted for these changes to take effect
-----------------------------------------------------------------------------------------------
WINDOWS 98 with ICS enabled, do the above plus:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\ICSharing\Settings\General\
Add a String value and name it:  InternetMTU      then set the value to:  1454
or modify it to this.
This key may also be removed completely rather than changing it.
See http://support.microsoft.com/support/kb/articles/q230/1/16.asp
-----------------------------------------------------------------------------------------------
WINDOWS NT/2000
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters
Add a DWORD value and name it:  MaxMTU      then set the value to:  000005AE
or modify it to this.    (that's 5 zero's+ and will equal 1454)

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters
Add a DWORD value and name it:  TcpWindowSize      then set the value to:  0000ffff
or modify it to this.    (that's 4 zero's and 4 F's and will equal 65535)
Computer must be rebooted for these changes to take effect
-----------------------------------------------------------------------------------------------
It may be easier and safer to just send the customer here, but remember to disclaim it and remind them to backup their registry first.

Note: EnterNet has been modified recently to support lower MRU sizes. The MTU/MRU sizes are normally negotiated during the connection phase, and then passed up to the TCP/IP configuration to control the TCP Max Segment Size (MSS). In the case of Windows, there was no way to update the TCP protocol dynamically. Starting with version 1.31 for Windows, and version 1.09b for Mac, the TCP Max Segment Size is now settable at install time to a default of 1454 for Windows, and 1400 for Mac OS. This is the optimal setting for these platforms, and should not be modified by the user. The MTU/MRU negotiation is no longer used for this feature, so you may see some Configuration Rejects at the protocol level if you're running traces, but this can be ignored. - Network Telesystems
 

Networking Multiple Computers with DSL
 
It's pretty simple to do with a hub. This does not imply that your ISP encourages networking or that they should tech a network problem. This information is just here in case the user is asking for the best (or easiest) way to share the DSL connection with a couple of computers. Use the appropriate cable (may be straight-through or crossover depending on router) and run it from the router to the uplink port on the hub. Use straight-through cables to hook the computers into the standard ports on the hub. Install Enternet 100 on each machine and your done as far as the connections go. Each machine should have firewall software installed as well as the user would most likely have File and Printer sharing enabled. If the user is trying to use ICS, Sygate, Wingate, Winroute, or any other sharing and/or firewall software they are totally on their own. In these cases they'll need to remove or disable these types of programs and connect the computer directly to the router before the ISP will tech the call.
