Adsl wire will not fit grey adsl port on the new modem-router, as the wire that we currently use is a screw in and the port is a plug in

a POTs (plain old telephone) line should never be connected to a router. that adsl filter does not make a phone line share a data line.
ADSL is a type of internet service supplied over a phone line. think of it as raw (unusable) when its on the phone line. then you use your dsl filter/splitter to feed the raw internet into a special dsl modem and the other port can be used by a standard phone.

you will know a dsl modem when you see it because its uplink or internet port will only be big enough to fit a phone cord into, not an internet cord. these dsl modems then feed usable internet to your routers and all devices on your network. but, like i said before, at this point it is too late for your phone and internet to share the same wire.

OK, thats not entirely true

pin out of RJ45 internet
1=orange/white *
2=orange *
3=green/white *
4=blue
5=blue/white
6=green *
7=brown/white
8=brown

1,2,3+6 are used in a typical network

if your network is typical you can "get fancy" and use 4,5,7+8 for telephone or even put 2 data lines on the same wire (not recommended for long distances). however, this may involve cutting some wires and splicing them together or something.

Here's a link to the Cisco (Linksys) site with directions on how to connect your range expander.

MT-800 is is just an ADSL modem. The cable from the modem connects to the WAN port on the router. A second cable goes from one of the LAN ports to the computer(s).
Here is the secret - Press the reset on the router for ten seconds (one thousand, two thousand...) AFTER this, unplug the power from the modem for ten seconds and then plug the power back in. Do it in this order.
The first step clears the router and finds the computer.
The second step resets the modem and tells it to find the router.
Enjoy your Internet!

First: Connect your computer directly to the ADSL modem. It has an Ethernet port.
If you can't get to the Internet while your computer is connected directly to the modem, then ytour router never will either. Call ISP if you can't connect to the Internet when directly conencted to the modem.
Next: Check your router wires again, The modem must be connected to the "special" port on the router. Look at the router. There is one port separated from the rest. Connect the modem to that port. Conenct to the Internet.
Still no Internet?
Reset your router by pushing a stylus (straightened-out paperclip) into the reset "hole" on the router (with router powered ON).
Push & hold for 30 seconds or until the lights do their reset dance. Connect to the INternet.

HI

A flashing ADSL light on the router means its not getting constant broadband signals. Make sure it is connected to the adsl filter without any extensions and the filter should be directly connect to the main phone socket and not to an extension socket. Also check if the phone socket has 1 or more than 1 ports on it. If it has two port its most likely a SSFP socket which does not require a filter as it is inbuit.If all the connections are fine try changing da filter.

Unplug the plug (from phoneline) on back of USB modem, plug into Zoom router. Plug one end of an ethernet cable into router and one end into your PC. Type http://10.0.0.2 into a web browser (eg. Firefox or Internet explorer) username/password is admin/zoomadsl go to basic setup and input your ISP username and password (the one given to you by your internet provider) under PPP. Click configure my connection. Save changes and then write to flash (both buttons on bottom of page)

The ADSL, Ethernet, and USB ports are located at the back of a Linksys modem. These ports are where the phone cable and computer will be connected. The ADSL Line should be connected to the ADSL port and the computer either be connected to Ethernet or the USB port., If u r using a ethernet cable no need to run the setup cd just connect the ethernet cable and contact ur isp..
do not worry about ur sagem modem, let it be inside.. just connect ethernet cables alone..

To setup a Linksys ADSL Modem with usb cable you need to perform two steps:

1. Connecting the Devices Together
2. Installing the USB Driver

Connecting the Devices Together
Step 1:
Connect the phone cable to the wall jack with ADSL service and then connect the other end to the ADSL port of the modem.
Step 2:
Make sure the power adapter is plugged to an available power outlet.
Step 3:
Connect the USB to the USB port on the back of the modem and then connect the other end top the USB port of the computer.
Step 4:
Power on the modem. After connecting the device together, install the USB driver. For instructions, follow the steps below.
Installing the USB Driver
Step 1:
Power on the computer.
Step 2:
When the Hardware Update Wizard window appears. Click Install the software automatically (Recommended).
NOTE: Windows XP has pre-installed drivers for the ADSL2MUE and will automatically install the USB driver for the modem.
Step 3:
Click Finish.
