Help to Install an AT&T DSL Motorola Modem

AT&T provides its DSL customers with a Motorola 2210 DSL modem, specially configured for use with its networks. These modems are designed for ease of installation. All you need to do to get the device operating is run an installation program, connect a few cables and configure the modem for use with your network.

Installation

1. Before you begin, you should spend some time figuring out how you wish to integrate your DSL modem into your home network. If you only have one computer, this may not be much of an issue. However, multiple computers will require use of a networking hub and enough Ethernet cabling to reach all of your devices. Alternatively, you can attach a wireless router to your modem and connect your computers that way. Determining the approach that will work best for you depends on the location of the various computers and how many walls stand between them and the modem.
   
   Once you've planned out your network, the next step in the installation process will depend on the type of your computer you are using. If your computer runs Windows, insert the installation CD that came packaged with your modem. An installer application will launch automatically (if, for some reason, it does not, you can browse the CD's contents and launch the installer manually). Follow the onscreen instructions and the installer will guide you through the process of connecting your modem to the DSL line and network cable. If you are using a Macintosh, you will have no such installer to help guide you. Instead, make the various cable connections in this order: power supply to power jack, DSL cable to DSL port (the one furthest left) and Ethernet cable to Ethernet port. The various cables have unique connectors, which will aid you in determining which port to use.

Connecting

2. Once you have your modem connected, launch your computer's web browser and navigate to the following address: 192.168.1.254. This will open the modem's web-based configuration screen. As it's your first time using the modem, you will be prompted to select a password for future use. Enter your login info when prompted (leave the user name as "admin") and click on the button labeled "Connect." At this point, the modem should be ready for use. However, your ISP may provide their own set of configurations for you to input into your operating system's "Network" settings (usually found in a section of the operating system labeled "System Preferences" or "Control Panels").

How to Fix the Xbox 360 “MTU Too Low” Problem with the Qwest Actiontec Q1000 DSL Modem

NOTE: If you are coming to this article after Googling the subject in frustration, here’s the quick-fix for you: Upgrade the modem’s firmware to QAQ01-31.00L.33 or later and you should be fine.

Qwest has been rolling their new high-speed fiber-optic DSL service out throughout Denver and Arizona for the last year or so (it’s not fiber-to-the-house, but with 40mbps available, who cares?). I’ve been a happy Qwest DSL client for about 3 years now — no complaints and more importantly — no outages.

When the fiber service started rolling out with speeds of 12mbps and 20mbps offered, I would reflexively crap my pants and throw myself into jealous rages because it wasn’t available in my area — that all changed last week.

Not only has Qwest rolled out fiber in my area, they also rolled out a new 40mbps/20mbps service as well for $115/mo — that doesn’t have any bearing on this post, it’s just awesome.

Anyway, I ordered the 20mbps/5mbps service which required an upgrade to the Actiontec Q1000 Qwest-branded modem. This is a Gigabit-capable 4-port modem with Wireless-N capabilities — I’ve had Actiontec equipment in the past from Qwest and it was garbage — replaced within months by 2wire which worked much better. Fortunately after a week with this Q1000 it looks like Actiontec may have cleaned some things up, the modem works fine with some basic firewall, port forwarding and advanced routing rules — this was something the older Actiontec modem that Qwest was selling couldn’t no — no joke, it literally couldn’t employ port forwarding rules AND the firewall at the same time — fail.

Anyway, after getting the Q1000 setup and the service enabled, I hooked my Xbox 360 via a WAP (I’ll give a review of later) and when I tried to get the Xbox online, I would get an error similar to the following:

Unable to connect to Xbox live, the MTU setting of your router is less than 1365 and must be increased. Please fix the problem and try again.

There is literally no MTU setting anywhere on the Q1000 — and reading through some other threads online, folks had suggestions ranging from disabling uPnP all the way to manually changing the MTU settings on your Windows machine (yea, I have no idea how they thought that would help).

As the threads went on, more and more folks said upgrading the firmware did the trick for them and magically the Xbox 360 started working again without any problems.

This sounded easy enough, but believe it or not, I was actually confused by the Upgrade Firmware screen on the Q1000 — on the older 2wire I had, there was a button that I clicked that would check the firmware against the remotely available version and then upgrade it if available — it also automatically upgraded itself constantly too (which got annoying after a while).

On the Q1000, there is simply a Download button and you end up with a file that has no identifying name or type, just firmware.

Believe it or not, this s all fine — and it worked great. So I’ll give you the instructions on how to update your firmware incase you are bamboozled by this — and get your Xbox 360 back online:

1. Go to 192.168.0.1 (or whatever IP address you gave your modem)
2. Login to your modem — I believe the default credentials are “admin” or “admin”/”admin” or just try password “admin” — it’s one of those.
3. Go to Utilities
4. Click Upgrade Firmware in the left menu
5. Click the Download button in section #1 — you will likely be prompted to safe a file named “firmware”, save it anywhere on your local computer.
6. Now scroll down to section #2, and click the Browse button and select that “firmware” file you saved.
7. Now scroll down to section #3, and click the Upgrade Firmware button, this will upload the file you just saved and apply it then restart the modem

And you should be all set. Let us know if you run into any problems. Happy gaming!

Mac OS X: Troubleshooting a cable modem, DSL, or LAN Internet connection

Symptoms

Mac OS X includes all the applications you need to access and use the Internet right away. But if your Internet connection doesn't seem to work, the following steps can get you back online. Tip: If you connect via PPPoE, follow the steps for PPPoE connections instead

Resolution

If you're on a local area network



Contact your network administrator instead of an Internet service provider (ISP). Information specific to modems may not apply to LAN users. LAN users may have hubs, switches, routers, or connection pods that cable and DSL users may not have.



If you use AirPort



Simplify the troubleshooting procedure by temporarily removing the base station from your network. Set up one computer to connect directly to your DSL or cable modem using the steps below. After re-establishing service to the computer, see the AirPort section below. Alternatively, troubleshoot from a more AirPort-specific perspective with the AirPort Troubleshooting Guide.



Check all cables and power supplies



Make sure all the cables related to the modem are plugged in and firmly inserted. This includes the modem's power cord, the cable from the modem to the computer, and the cable from the modem to the outlet. To be sure a connector is properly inserted, disconnect and reconnect it. Check to see if the cables have been cut, chewed, or otherwise damaged.



If you have any hubs or routers, check their cables and power supplies. If you have more than one power supply available for a type of hub or router, try swapping the power supplies. A defective power supply may affect network traffic.



Reset/power cycle modem hardware



Cycle the power on your DSL or cable modem by turning it off for a few minutes then turning it back on. Some ISPs recommend you unplug the modem's power cord. This is required if the modem does not have a power button. If the modem has a reset button, you can try it before or after cycling the power.



Check indicator lights on the modem



First, check to see if the DSL or cable modem has a "standby" light or button. Some popular modems may not connect to the Internet when in standby mode. If applicable, be sure the modem is not in standby mode.



Other indicator lights can provide useful information about cabling connections. A light named "Cable" or "Online," for example, indicates whether the ISP's network is available. A "PC" or "link" light indicates whether the hardware connection between the computer and modem is good. A positive link light almost always indicates that the Ethernet ports on each device are working properly, and thus a positive link light makes it very unlikely that an Ethernet port failure is causing the issue.



Tip: If the lights on your modem vary only between on and off and do not change color, then a "positive" light is one that is on. If the lights on your modem change color, a green light is more likely to mean positive than yellow or red.



If your link light is positive, skip to the Check Network preferences settings section. If there is no link, try modem and Ethernet hardware troubleshooting.



Broadband modem and Ethernet hardware troubleshooting



If the link light is off after you checked your cables and cycled the power, you need to re-establish the link before continuing. If your computer came with an Apple Hardware Test CD, use it to check for any issues with your hardware. If nothing is found, contact your Internet service provider. They may be able to remotely test your modem to see if it has failed. If nothing is found with the modem, replace the Ethernet cable, since it is the most easily replaced component.



If replacing the Ethernet cable does not establish the link, you will need a third Ethernet device to determine whether the computer or modem is failing to link. The third device could be a simple ("dumb") Ethernet hub with link lights (an inexpensive 10BASE-T hub found at any computer store will do), an Ethernet switch with link lights, another computer, a router, or a wireless base station.



When using a hub or switch to test, simply connect both the computer and modem to the hub or switch, then check the link lights on the hub or switch to see which of the other devices is not connecting. If you use another computer (Mac or PC) to test, check to see if the other computer has an Ethernet link light (many do not). If there is no link light on the computer, set up a file sharing connection to verify connectivity. If you use a router or base station to verify connectivity, connect as instructed in the device's documentation. If the router or base station has link lights, you may use the simple link light test.



If you are not able to use this type of test, do whichever of the following is more convenient for you: either exchange your modem with your Internet service provider or take the computer somewhere else where you make sure it works, for example, a neighbor, school, work, and so forth.



Be sure that your software settings are correct, as described in the Check Network preferences settings section below.



If you still cannot connect, you may have a DNS issue. Your Internet service provider's DNS service may not be working, or you did not configure it correctly.



If you still cannot connect and your cable modem link light is positive, but you haven't replaced the Ethernet cable yet, substitute a new or known-good Ethernet cable for the one you have been using.





Check Network preferences settings



Use Network preferences to verify your TCP/IP settings and that Built-in Ethernet is your primary network interface. Follow these steps:

1. From the Apple menu, choose System Preferences.
2. From the View menu, choose Network.
3. Choose Active Network Ports from the Show pop-up menu ("Advanced" from the "Configure" pop-up menu prior to Mac OS X 10.1).
4. Be sure that the checkbox for "Built-in Ethernet" is selected.
5. Drag Built-in Ethernet to the top of the Port Configurations list to make it the preferred, or primary, network interface.
6. Choose Built-in Ethernet from the Show pop-up menu.
7. Click TCP/IP. Follow your ISP's instructions for setting up this pane. For more information, see "Mac OS X: How to Connect to the Internet With Cable or DSL".
8. If you have made any changes, click Apply Now.

If you still cannot connect, you may have a DNS issue. Your Internet service provider's DNS service may not be working, or you did not configure it correctly.



If you still cannot connect and your cable modem link light is positive, but you haven't replaced the Ethernet cable yet, substitute a new or known-good Ethernet cable for the one you have been using.



Sharing the connection



If you have two or more computers trying to share an Internet connection, make sure your network is set up properly. You need to know if your ISP provides only one IP address or if it provides multiple IP addresses. If only one IP address is used, you must have a network router capable of sharing the connection, also known as network address translation (NAT) or "IP masquerading." Check the documentation that came with your router for setup information. Check with the person who set up your network, or with the router manufacturer for assistance.



An AirPort Base Station can share a connection with wireless clients.



Additional steps for AirPort

1. After successfully connecting to the Internet with the computer, disconnect the modem from the computer.
2. Unplug power cords for both the modem and the base station.
3. Connect the base station to the modem.
4. Plug the modem back in first, then the base station, and wait for the base station's indicator lights to cycle through their startup routine.
5. Start up a computer, and try to connect to the Internet using the base station. If you cannot, use the AirPort Setup Assistant (/Applications/Utilities/) to copy your computer's network setting to the base station. If you have an advanced network setup, you may need to use AirPort Admin Utility instead.

Get help from your ISP



If you have not resolved the issue with the steps above, contact your Internet service provider.
