Connect your computer directly to the Internet modem and make sure that you have Internet access directly from the modem.
If that is working properly then connect the modem to the Internet port on the router. Connect the computer to port 1 on the router.
Reset the router and configure it manually.

Im connected to my wifi internet in the office but i cannot open the internet . the brand of router is cisco WRT54G2VI, SERIAL #CSVO1HC21627, MAC.ADD 002369214852, ARROW SYMBOL UP DOWN 45103834, please...


If your computer shows you the little yellow triangle (limited connectivity) then you might have to reset the source of your internet, the modem if you can access it, by unplugging the power for 30 seconds. then reset your router by unplugging the power for 30 seconds so it can aquire a new IP address if you get the internet through dynamic settings. The router could also have a bad ethernet internet port. If you can connect to the router wirelessly and tried resetting it and if you can get internet being directly hooked up to the modem or source of internet such as a wall outlet...then your router may be bad.....if it is a Belkin...then it was junk to begin with.

Routor not connecting to modum


That is connect.
You will need to connect the router to the modem with the Ethernet cable.

First connect the computer to the modem with the Ethernet cable. Make sure that you can access Internet without router.

Connect the computer to the Ethernet port 1 and modem to the Internet port on Linksys router.
Open the setup page of the router.
Change the Internet connection settings according to the Internet service provider.
Create a wireless network and then connect your computer and other devices to the wireless network.

I need to connect cisco 2800 router to my pc through hyperlink


I think you mean hyperterminal? you need a cisco serial cable (blue) and a serial port on your PC, maybe a USB to serial adapter if there isn't one. Set hyperterminal to use the COM port you have plugged in to, speed 9600 8 bit no parity. (8N1).
Without the serial cable you need to know the router IP and password.

Adtran Atlas 550 alternatives


1: Would a Cisco 1720 provide a simple soltution for terminating a T1 to Ethernet 100 Mps I recommend a 1721 2: If this would not be an option, what Cisco box would provide the needed termination/routing I recommend a 1721 3: If a Cisco device could do this would it be necessary to replace them at both locations or could it communicate with the Adtran device. It depends on the topology of how your sites are interconnected to each other. Please describe in greater detail.
