Corrective Action

To obtain an IP address for the computer with the cable modem

Your Internet Service Provider (ISP) assigns either a static or dynamic IP address to the computer with the cable modem.

To assign IP addresses to the remaining computers and the All-in-One printer

Use AutoIP to assign IP addresses to the remaining computers and the printer. Do not assign a static IP address.

Wireless troubleshooting

No SSID

Probable Cause 1

Your access point is not broadcasting its network name (SSID) because the Broadcast SSID option is turned off.

Corrective Action

Access the Embedded Web Server and turn on the Broadcast SSID option.

Probable Cause 2

The access point (infrastructure) or computer (ad hoc) is out of range.

Corrective Action

In order to establish a good signal between the printer and access point (infrastructure) or computer (ad hoc), try doing the following things separately or in combination.

  • If there is a long distance between your computer or access point and the printer, move them closer together.

  • If there are metal objects (such as a metal bookcase or refrigerator) in the transmission path, clear the path between the printer and the computer or access point.

  • If a cordless telephone, microwave, or other device that emits radio signals transmitting at 2.4 GHz is nearby, move it farther away to reduce radio interference.

NOTE: Devices like wireless speakers or wireless gaming accessories can emit radio interference at 2.4 GHz. You can verify this on your wireless desktop or laptop computer by viewing sporadic signal bars in your Wi-Fi status utility. Repositioning your computer away from these sources of signal interference can improve your computer network performance. For example:
  • Do place the AP/router in a central room.

  • Do not place wireless entertainment devices between the AP/router and wireless computer.

  • Do not place wireless entertainment devices between the AP/router and Wi-Fi All-in-One printer.


Probable Cause 3

The SSID is not visible because it is at the bottom of the list.

Corrective Action

Press to scroll to the bottom of the list. Infrastructure entries are listed first and ad hoc entries last.

Probable Cause 4

The access point firmware needs updating.

Corrective Action

Check for firmware updates for your access point on the manufacturer's Web site. Update the firmware on the access point.

Probable Cause 5

Your wireless adapter on your computer is not broadcasting the SSID (ad hoc).

Corrective Action

Verify that the wireless adapter is broadcasting the SSID. Print a network configuration page from the All-in-One printer, and verify that the SSID for the wireless adapter appears on the network configuration page. If the wireless adapter is not broadcasting the SSID, see the documentation that came with your computer.

Probable Cause 6

The firmware for the wireless adapter on your computer needs updating (ad hoc).

Corrective Action

Check for firmware updates for your wireless adapter on the manufacturer's Web site, and then update the firmware.

Probable Cause 7

An Ethernet cable is connected to the printer.

Corrective Action

Unplug the Ethernet cable.

Weak signal

Probable Cause

The access point is too far away or there is interference.

Corrective Action

  • If there is a long distance between your computer or access point and the printer, move them closer together.

  • If there are metal objects (such as a metal bookcase or refrigerator) in the transmission path, clear the path between the printer and the computer or access point.

  • If a cordless telephone, microwave, or other device that emits radio signals transmitting at 2.4 GHz is nearby, move it farther away to reduce radio interference. See the note on .

Cannot connect to network

Probable Cause 1

The equipment is not turned on.

Corrective Action

Turn on the networked devices, such as the access point for an infrastructure network, or the computer for an ad hoc network. For more information on how to turn on the access point, see the documentation that came with your access point.

Probable Cause 2

The All-in-One printer is not receiving a signal.
