Using a Bluetooth wireless device
A Bluetooth device provides short-range wireless communications that replace the physical cable
connections that traditionally link electronic devices such as the following:
●Computers (desktop, notebook, PDA)
●Phones (cellular, cordless, smart phone)
●Imaging devices (printer, camera)
●Audio devices (headset, speakers)
Bluetooth devices provide peer-to-peer capability that allows you to set up a personal area network
(PAN) of Bluetooth devices. For information on...

NOTE:Wireless networking devices are included with select computer models only. If wireless
networking is not listed in the feature list on the side of...

Network icon is not displayed
If the network icon is not displayed in the notification area after you configure the WLAN, the software
driver is either missing or corrupted. A Windows “Device not Found” error message may also be
displayed. The driver must be reinstalled.
To get the latest version of the WLAN device software for your computer, follow these steps:
1.Open your Web browser and go to 
http://www.hp.com/support.
2.Select your country or region.
3.Click the option for software and driver...

WLAN connection is very weak
If the connection is very weak, or if your computer cannot make a connection to a WLAN, minimize
interference from other devices, as follows:
●Move your computer closer to the wireless router or access point.
●Temporarily disconnect other wireless devices such as a microwave, cordless phone, or cellular
phone to be sure that they are not interfering.
If the connection does not improve, try forcing the device to reestablish all connection values:
1.Select Start > Control Panel...

Using the modem (select models only)
The modem must be connected to an analog telephone line using a 6-pin, RJ-11 modem cable
(purchased separately). In some countries or regions, a country- or region-specific modem cable adapter
(purchased separately) is also required. Jacks for digital PBX systems may resemble analog telephone
jacks, but they are not compatible with the modem.
WARNING!Connecting the internal analog modem to a digital line can permanently damage the
modem. Immediately disconnect the...

Connecting a country- or region-specific modem cable adapter
Telephone jacks vary by country or region. To use the modem and the modem cable (purchased
separately) outside the country or region in which you purchased the computer, you must obtain a
country- or region-specific modem cable adapter (purchased separately).
To connect the modem to an analog telephone line that does not have an RJ-11 telephone jack, follow
these steps:
1.Plug the modem cable into the modem jack (1) on the computer.
2.Plug the...

Adding new locations when traveling
By default, the only location setting available to the modem is a location setting for the country or region
in which you purchased the computer. As you travel to different countries or regions, set the internal
modem to a location setting that meets the operating standards of the country or region in which you
are using the modem.
As you add new location settings, they are saved by the computer so that you can switch among settings
at any time. You can add multiple...

Solving travel connection problems
If you experience modem connection problems when using the computer outside of the country or region
in which you purchased it, try the following suggestions.
●Check the telephone line type.
The modem requires an analog, not a digital, telephone line. A line described as a PBX line is
usually a digital line. A telephone line described as a data line, fax machine line, modem line, or
standard telephone line is usually an analog line.
●Check for pulse or tone dialing.
An...

7.Clear the check box for Wait for dial tone before dialing.
8.Click OK twice.
Connecting to a local area network (LAN)
Connecting to a local area network (LAN) requires an 8-pin, RJ-45 network cable (purchased
separately). If the network cable contains noise suppression circuitry (1), which prevents interference
from TV and radio reception, orient the circuitry end of the cable (2) toward the computer.
To connect the network cable:
1.Plug the network cable into the network jack (1) on the computer....
