How do I configure to remotely monitor a DVRC264-16ME with Apple based computers?


Remote access setup is the same a with a PC. Each router is different but the apple versus PC issue is not. Once remote access is setup, you will access the DVR interface using the IP address you have chosen. If you need help setting remote access up, call us. We offer the service for minimal cost. If you want to do it yourself which can take hours and will possibly make you pull your hair out, then research your specific router model number and make sure you port forward the proper ports that your DVR or NVR asks for and insert them into your router firewall, pointing them to your DVR or NVR's local IP address.

How to forward port for a IP camera on a Huawei 655b modem ?


You can't port forward on a modem. On a router, yes. You just need to set the a static IP on the camera outside of your DHCP range. Then select a port above 1024 and set that port to point to the static IP. You should only need to port forward UDP. Optionally you would want to setup a dyndns account since your public IP from your ISP is dhcp and therefore doesn't always stay the same.

My linksys w/2phone ports cannot hook up with the ethernet


Most Cable Internet Service Providers (ISPs) use Media Access Control (MAC) Address authentication to establish Internet connection for end-users. MAC address is a unique identifier assigned to the network adapter/s of the computer.
To set up your Linksys router to work with a Cable ISP, you have to enable the MAC Clone feature of the router. MAC Cloning is a procedure which enables a router to copy the MAC address of the computer registered with the ISP.
To set up a Linksys router with Cable connection, you need to perform four steps using the computer that's been registered with the ISP:
i. Verifying Internet Connection
ii. Connecting the Devices Together
iii. Checking the Router's LEDs
iv. Setting Up a Linksys Router for Cable Internet Connection

Verifying Internet Connection
Connect the computer to the Broadband modem using an Ethernet cable without the router installed. If you cannot get online, contact your ISP. If it's online, use the computer to set up the router.
NOTE: Some cable modems use the USB port. If the physical connection is via USB port, you may not be able to go online via Ethernet connection. Contact your ISP to have the Ethernet port of the modem configured.

kb17251-001_en.png NOTE: The image may vary depending on the computer and modem you're using.
Connecting the Devices Together
After confirming the Internet connection through the modem, connect the modem to the Internet port of the router; connect the computer to any of the four Ethernet ports at the back of the router. For instructions, click here.
Checking the Router's LEDs
After connecting the devices together, check the lights on the front panel of the router. Ensure that the Internet light, as well as numbered light corresponding to the Ethernet port where the computer is connected, is lit. For further instructions, click here.
Setting Up a Linksys Router for Cable Internet Connection

Step 1:

Step 4:
Click Save Settings.

Step 5:
Click the Status tab.

kb17251-004_en.png

Step 6:
Check the Internet IP Address. If the Internet IP Address has numbers, this means the router has been properly configured. You should now be able to access the Internet. If you're still unable to access the Internet, powercycle the modem, the router and then restart the computer.

kb17251-005_en.png

NOTE: If the IP address is still 0.0.0.0, click IP Address Release then, click IP Address Renew. If this does not change the IP Address, powercycle the modem, the router and then restart the computer.

Cable modem internet works when directly plugged into desktop, but when run through the router, no connectivity


Most cable Internet Service Providers (ISP) use a Media Access Control (MAC) Authentication to establish Internet connections for end-users. A MAC address is a unique 48-bit (6-byte) integer that is attached to an Ethernet NIC for each computer. To set-up your Linksys router to a Cable ISP, you have to do MAC Cloning. MAC Cloning is a procedure which enables a router to copy the MAC address of the PC that's registered with the ISP.
To setup a Linksys router with Cable connection you need to perform five steps:
  1. Verifying Internet Connection
  2. Connecting the Devices Together
  3. Checking the Router's LEDs
  4. Configuring a Linksys Router for a Cable Connection
  5. Power Cycling
NOTE: Before proceeding, use the computer that can go online when connected to the modem and follow the steps below.
Verifying Internet Connection
Connect the Broadband modem to the computer using an Ethernet cable without the router installed and make sure that the Internet connection is active. If it is not, contact your ISP. If it can go online, the PC connected to the modem is the one that's registered with the ISP.

kb4682-001_en.png NOTE: The image may vary depending on the computer and modem you're using.
Once an active Internet connection is established through the modem, connect the modem and the computer to the router by following the instructions below.
Connecting the Devices Together
After ensuring that you have an active Internet connection, connect the modem to the router's Internet port and the computer to any of the four Ethernet ports. For instructions, click here.
After connecting the devices, check the LEDs by following the instructions below.
Checking the Router's LEDs
The Linksys router's front panel will indicate the status of the connection. After connecting the broadband modem to the WAN or Internet port, the computer to an available numbered port and powering on the router check the lights on the front panel of the router. For instructions, click here.
After checking the router's LEDs, configure the router for cable Internet. For instructions, follow the steps below.

Cant setup or connect to internet through router


Different ISPs require different configurations. If you have a Linksys router, such as the WRT54G, there are 2 ways on how you can configure it, either by running the Setup CD or by doing manual configuration. This particular router has its own web utility and you can access it by typing its IP addres on your web browser, ex. http://192.168.1.1. By default, it doesn’t have any username and its password is admin.

Once you’re inside the setup page, you can configure now the router for DHCP, PPPoE or STATIC IP settings. For DSL customers using a PPPoE account, some modem needs to be configured into BRIDGE MODE first and then the router will be set to PPPoE with the correct username and password (given by ISP). If your a DHCP account, modem doesn’t require any configuration. It will work with its default setting and the router would be set to DHCP. Once done, powercycle your devices to establish internet connection.

Wireless network broken, access to WRT54G & Motorola 2210-02 via http.. denied


I have att yahoo dsl which I installed about a year ago. The process required bridging the ADSL Modem (in my case a speedstream 4100) and accepting dynamic IP addresses and configuring PPPoE on the WAN side of my Linksys router. The ATT support person walked me through the entire process over the phone even though I was comfortable with making the Linksys configuration changes as I had to do the same in China without technical support. The modem configuration was no more difficult than the router configuration as it was performed from a web browser too. The biggest warning was that to reverse the modem change (if desired) required use of a reset button because the web interface was disabled as a result of the configuration change. My advice to you especially if you are willing to attach the Linksys router to the telco modem is to contact the ATT highspeed DSL support line and see if they will walk you through it like they walked me through it. Reviewing your Linksys User's Guide and understanding the configuration of that device would probably be appreciated by the ATT Support person as well as assuring you can access the Linksys router to configure it during the call.
