**DSL vs Dialup**
## <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 PHOHNE LINE**
* 2 types of dsl
* ADSL 1.5 TO 9MB DOWN 16-640 KB UP
* SDSL sYNCRONOUS OR SYMETRIC 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_ reccoment)
## <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=0-25 192.168.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
----
10 contact SBC to obtain more ip addresses 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 enternet) -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
2nd Step of [[TroubleShooting]] -Light Status Modem
\*Power
* * on = good
* off = bad
1. verifty 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. swithc 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 perorm 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
if you are unable to recieve an IP address verify wiring verify account verify settings
