## <a name="Digital_Subscriber_Line_DSL"> </a> Digital Subscriber Line - DSL
* Faster
* More Expensive
* Always On
* Can use phone line while online
* Different Equipment
**THEY BOTH USE PHONE LINE**
* 2 types of dsl
* ADSL ASYNCRONOUS OR ASYMETRIC (example: 1.5 TO 9MB DOWN 16-640 KB UP)
* SDSL SYNCRONOUS OR SYMETRIC (example: 3MB DOWN 3MB UP)
What equipment is needed
* DSL / Cable Modem
* Ethernet adapter
* Category 5 cable (ethernet cable)
* RT-45
* USB universal Serial Buss
* (can be used but _do not_ reccomend)
## <a name="IP_Addressing"> IP Addressing </a>
* 0.0.0.0 => 255.255.255.255
* 4,228,250,625
### <a name="Private_IP_Address_Ranges"> Private IP Address Ranges </a>
* X=0-255
* 192.168.x.x - used w/ Routers& Configurable Modems
* This range is the most typical private range used.
* 10.x.x.x - Used w/ routers or configurable Modems.
* 172.16.x.x - Used w/ routers. (this is a typical range used by businesses)
### <a name="Non_Routable_Range"> Non-Routable Range </a>
* 169.254.x.x - Non Routable IP Range telling you something is broken Created by Microsoft for troubleshooting purposes
* 127.x.x.x - Range reserved for local host (norton's, microsoft, etc.)
## <a name="Acronyms"> Acronyms </a>
* IANA - internet Assigned Numbers Authority
* Distribute IP Address to backbone Co. ie AT&T, Bell Co.
### <a name="Public_IP_Addressing"> Public IP Addressing </a>
* How to become an ISP
1) Contact SBC to obtain IP Addresses:
* 300 members
* 66.137.124.1 - 66.137.124.101
2) Distribut IP Addresses Gateway Address = IP Addresses of the DHCP Server (endpoint)
DHCP - Dynamic host control protocol
----
1) contact SBC to obtain more ip addresses
* 500 Members
* 68.124.138.1 - 68.124.138.151
2) Distribute IP addresses
Static - Specified IP address that never changes
## <a name="Authentication_Processes"> Authentication Processes </a>
**MAC Addressing** \*MAC address- Physical address of any device that can carry an internet connection
* it authenticates through the modem or next piece of connecting equipment's MAC Address
PPOE - Point to point protocol (over the ethernet) -requires a customer to logon w/user/password before reciving an ip address the only os w/ppoe built in XP&MACX they install pppoe software or get a router or configurable modem.
Trouble shooting DSL / Cable
## <a name="1st_Step_of_Trouble_shooting_POW"> </a> 1st Step of Trouble shooting - POWERCYCLING
### <a name="take_down_order"> take down order </a>
* unplug modem from power supply
* unplug any connecting equipment from Power Supply (router, Switch, etc)
* SHUTDOWN (not restart) the pc
### <a name="bringing_up_order"> bringing up order </a>
* plugin the modem into power supply
* plug the connecting equipment into the power suply
* restart the PC
## <a name="2nd_Step_of_Trouble_Shooting_Lig"> 2nd Step of Trouble Shooting -Light Status of </a>
Modem
* Power
* on = good
* off = bad
1. verify it is plugged in
2. check for power at the source (switch?)
* dsl/link/sync
* on = good
* off = bad
1. check connection between wall and modem phone line dsl + co-AX cable)
2. verify it worked previously nothing changed, (moved, jacks, storm)
3. verify all connecting information (PPPOE, MAC address, static)
* Enet/USB/PC/Sync/Link
* on = good
* off = bad
1.check connection between modem and pc ethernet usb
2. switch cable ends crossover vs straight through
3. check the ethernet adapter
* Act/Activity/Data/(10/100) - TX/RX
* * on or flashing = good
* off = bad
1. This light has no bearing in your troubleshooting
* Test/Alarm/Standby
* off = good
* on = bad
1. This light must be off in orter to troubleshoot.
Where to find IP information - IP configuration LC start => LC run => tye commands or cmd => LC OK button => type "winipcfg" => press enter => chose NIC in dropdown
1.) Adapter Address = MAC address
2.) IP address - NIC
3.) Gateway Address - DHCP Server
* If there is **NO** NIC in the dropdown box
* verify cust has startup disk or cab files (win\*.cab)
* Rip and reinstall TCP/IP
* If it says Media Disconnectd or IP = 0.0.0.0
* Not connected
* verify lights on modem
* verify wiring
\* if they are reciving an IP address of 169.254.x.x
* they are set to DHCP, but not contacting DHCP Server
- Its broken and try to release /renew ip address
## <a name="what_will_happen_next"> what will happen next </a>
1. will recieve IP Address
2."Unable to contact DHCP Server" Error
* try to release and renew again
3. "DHCP Server unavailable revewing IP address" - Error
* try to release and renew again
4. "No adapter in a state permissable to perform operation" Error
* configured to static
* check settings
5. "unable to perform operation" or " operation was attempted on something that is not a socket" Error \* winsock Error
* * email winsock fix
* Send to shop
## <a name="if_you_are_unable_to_recieve_an_"> if you are unable to recieve an IP address </a>
* verify wiring
* verify account
* verify settings
## <a name="where_to_go_and_check_settings"> where to go and check settings </a>
* DLC My Comp > DLC Control Panel > DLC Network >highlight TCP/IP => Ethernet Adapter - - LC Properties button
* IP addresses tab => Static - Specify an IP address Dynamic Obtain Automatic
* Gateway tab => Static - 1 gateway address entered Dynamic None entered
* DNS Tab - ISP Specific
PING packet internet Groper
Sonar for the internet
3 ways to tell if you are connected to the internet
1. ping outside address
1. thpe winipcfg => press enter => choose NIC in drop down box obtain ip address and gateway address (put in tracker notes)
1. type ping ipaddress press enter ie: ping 192.168.1.100 ethernet adapter
* good response = 4 sent
* Bad response - 4 sent 0-3 recieved / 1-4 lost
1. Check for a firewall => disable it and run ping again
2. rip and reinstall TCP/IP => Run ping again
3. check the ethernet adapter
1. type ping gatewayaddress => press enter (ie ping 192.168.1.1) DHCP Server Bad Response
1. 1. ) check for a firewall => disable => run ping again
2. ) Rip and reinstall TCP/IP => run ping again
3. ) make sure network allows ping (shawneeling and madison)
4. ) verify all connectings information (pppoe, <MAC address,, Static)
5. ) Broken - Sent ticket to network
2. type ping www.yahoo.com => press enter good response = connected
1. type ping yahoo's ip press enter (ie ping 216.109.118.76)
* if you get a bad response on the domain name and good response on IP check DNS
* after entering DNS if you still cant pull the site by domain or IP => winsock error - email or shop
## <a name="Checking_the_NIC_Network_Interfa"> </a> Checking the NIC - Network Interface Controller
DLC My Comp => DLC Control Panel => DLC System => LC Device Manager Tab => LC (+) next to network adapters
If there is Red X
* Means the device has been disabled RC the device LC Enable.
If there is Yellow!
* Means the PC recognizes the device but does not know how to use it
* Uninstall/Reinstall NIC - RC the device => LC Uninstall => LC OK => Reboot PC => Follow hardware wizard
* to uninstall they must have drivers disk or it must be original to PC
if there is yellow or no network adapters (check other devices for PCI Adapter)
* means PC has no idea what device is or how to use it
* uninstall reinstall NIC
* Same as Above

* NAT = Network Address Translator
* WAN = Wide Area Net
* LAN = local Area Network
* LAN IP = Gateway for each PC
How do you access a routers interface, like to enter a static IP address?
1. run an IP configuration and obtain the GW address (should be 192.168.x.x or 10.x.x.x )
2. open your web browser and enter the GW address into the address bar and click "go"
3. at the username / password pop up, you enter the default login => LC OK button
