Wireless networking problems
Wireless networking problems
This section provides general troubleshooting tips for 
networking problems, specifically wireless (Wi-Fi®) 
networking.
The terms and concepts used assume a basic 
understanding of networks, and may be for more 
advanced users. If you need assistance or if you are not 
familiar with the terminology, please see Windows
® Help 
and Support or contact your computer technician.
❖If your device is equipped with an internal Wi-Fi
® 
adapter, verify that Airplane mode is OFF, see “Setting 
up for communications” on page 70.
❖Verify that your device can detect access points or 
routers. If it can detect a Wi-Fi
® access point or router 
then it may be a configuration issue.
❖Verify that signal strength is good using the utility 
provided with the Wi-Fi
® adapter.
❖If another device is on the same network, verify that it 
has network access, and can connect to the Internet. If, 
for example, the other device cannot browse to a public 
Web site, the ISP’s (Internet Service Provider) service 
may be disrupted.
❖Verify that the Service Set Identifier (SSID), or network 
name, is correct - i.e., that it matches the SSID assigned 
to the access point you are attempting to connect 
through. SSIDs are case-sensitive. 
❖Check the Windows
® Control Panel's Device Manager to 
verify that the Wi-Fi® adapter is recognized by the 
Windows® operating system, and that the driver is 
loaded. To access the Device Manager, swipe in from the 
right edge of the screen. When the Windows
® charms 
appear touch the 
Search ( ) charm, and then type 
Control Panel. Touch Control Panel, and then select 
System and Security, and then System. Launch the 
Device Manager and carefully note any error messages 
- 
these will be very helpful if you should confer with a 
support technician at a later time.
NOTE

Develop good computing habits
To enable/disable the wireless antenna, use the Airplane 
mode switch located under Networks, see “Setting up for 
communications” on page 70.
❖Use IPCONFIG to verify that the device has a useful IP 
address - one other than the private address of 
169.254.xxx.xxx assigned by Windows
®.
1Swipe in from the right edge of the screen. When the 
Windows
® charms appear, touch the Search () 
charm. Then touch the Search field and begin typing 
Cmd.
2Touch 
Command Prompt.
3Enter 
IPCONFIG/ALL, and then press ENTER.
The IP address for each active network adapter will be 
displayed.
❖If you have enabled any security provisions (closed 
system, MAC address filtering, Wired Equivalent Privacy 
[WEP], etc.), check the access point vendor's Web site 
for recent firmware upgrades. Problems with WEP keys, 
in particular, are frequently addressed in new firmware 
releases.
Develop good computing habits
Save your work frequently.
You can never predict when your device will lock, forcing you 
to close a program and lose unsaved changes. Many 
software programs build in an automatic backup, but you 
should not rely solely on this feature. Save your work! See 
“Computing tips” on page 49 for instructions.
On a regular basis, back up the information stored 
on your internal storage drive.
Use Windows
® to back up files, or the entire device, to an 
external hard disk. Here are some ways you can do this:
❖Use the Windows
® operating system to back up files or 
your entire device to an external hard disk.
❖Copy files to a rewritable external storage device.
❖Connect your device to the office network and copy files 
to your network partition.
NOTE 
						

							93If Something Goes Wrong
Develop good computing habits
Some people use a combination of these methods, backing 
up all files weekly and copying critical files to external media 
on a daily basis.
If you have installed your own programs, you should back up 
these programs as well as your data files. If something goes 
wrong that requires you to reformat your internal storage 
drive and start again, reloading all your programs and data 
files from a backup source will save time.
Read the documentation.
It is very difficult to provide a fail-safe set of steps you can 
follow every time you experience a problem with the device. 
Your ability to solve problems will improve as you learn about 
how the device and its software work together.
Get familiar with all of the documentation provided with your 
device, as well as the information that may come with the 
programs and devices you purchase.
Your local computer store or book store sells a variety of 
self-help books you can use to supplement the information 
in the manuals.
Data and system configuration backup in the 
Windows® operating system
The Windows® operating system offers some easy-to-use 
features for backing up your Windows® settings and your 
data - documents and other important files. Take advantage 
of these features to protect yourself from much more difficult 
and time-consuming restoration procedures, and to 
safeguard your valuable data from loss.
Saving system configuration with restore 
points
The System Restore feature of the Windows® operating 
system quickly creates restore points - ‘snapshots’ of your 
Windows
® operating system configuration - and saves them 
for later recall. If you experience problems after installing 
some new hardware or software, you can easily select a 
previously established Control Point to ‘turn back the clock,’ 
restoring the Windows
® operating system to the state it was 
in just prior to the installation. This is much easier and more 
effective than uninstalling the hardware or software, which 
often leaves behind unwanted files and settings. It is also 
easy to undo a restore point selection, if you change your 
mind.

Develop good computing habits
Follow these steps to create a restore point using the 
System Restore utility:
1Swipe in from the right edge of the screen. When the 
Windows
® charms appear, touch the Search ( ) charm. 
Then touch the Search field and type 
Control. Touch 
Control Panel in the list that appears.
2Touch 
System and Security, and then System.
3In the left pane, touch

The System Protection tab of the System Properties 
window appears.
4Touch 
Configure.
5Under 
Restore settings select Turn on System 
Protection
.
6Touch 
OK.
7Touch 
Create.
8Touch the input field, and enter a name that is 
descriptive enough to be easily understood in the future, 
such as “Before installing Brand X Accounting app.” 
Then touch 
Create.
The Windows
® operating system creates the restore 
point, automatically stamps it with the current date and 
time, and displays a message that the restore point was 
successfully created. 
9Touch 
Close.
Then, at a later time, you can re-establish your Windows
® 
configuration using the saved restore point. To do this:
1Swipe in from the right edge of the screen. When the 
Windows
® charms appear, touch the Search ( ) charm. 
Then touch the Search field and type 
Control. Touch 
Control Panel in the list that appears.
2Touch 
System and Security, and then System.
3In the left pane, touch 
System Protection.
The System Protection tab of the System Properties 
window appears.
4Touch 
System Restore...
5Touch Next.

6Touch the Restore point you want to use, and then touch 
Next.
The time stamp and description of each Restore point is 
displayed.
At this point you can touch “Scan for affected programs” 
to determine what the impact of using the chosen 
Restore Point will be.
7Verify that the Restore point you chose is the correct 
one. If it is not, touch 
Back to return to the previous 
step.
8Close all programs and save all open files.
9Touch 
Finish, and then Ye s to begin the system restore.
Yo u r  W i n d o w s
® operating system configuration will now 
be restored to the state it was in when the chosen 
restore point was created, and then the device will be 
automatically restarted.
Backing up your data or your entire device 
with the Windows® operating system
The most valuable component of your device system is the 
data you create and store on its internal storage drive. Since 
problems with either hardware or software can make the 
data inaccessible or even destroy it, the next most valuable 
component of your device system may be a recent backup 
of your data.
Fortunately, the Windows
® operating system offers a 
convenient way to back up your device or just your 
important files to or hard drives. An external hard drive is 
recommended in case the internal storage drive fails. No 
additional software is required.
Follow these steps to back up your device or files to external 
media, or a storage drive:
You cannot back up the device while running on battery 
power. Connect an optional USB/AC adaptor before 
continuing.

Then touch the Search field and type 
Control. Touch 
Control Panel in the list that appears.
2Touch 
Save backup copies of your files with File

screen, and search for “back up files,” see “The Windows® 
operating system can help you” on page 84.
General tips for installing hardware and 
software
Here are a few tips to help ensure safe and easy installation 
of new hardware (printers, pointing devices, external hard 
drives, scanners, etc.) and software (applications like 
Microsoft
® Office and Adobe® Photoshop®, or utility software 
such as special toolbars for your web browser). 
❖Create a restore point (refer to “Saving system 
configuration with restore points” on page 93). Before 
installing anything, use the System Restore utility to set 
a restore point (see the section titled restore points). If 
anything goes wrong, you will then be able to easily 
restore the Windows
® operating system to the state it 
was in prior to the installation, undoing any changes that 
the installation process introduced.
❖Back up your critical data (see “Backing up your data or 
your entire device with the Windows
® operating system” 
on page 95).
❖Have your back up media on hand in case you need any 
files from them. 
❖Do not guess - follow directions carefully! It is often 
necessary to run an installation utility first - before 
connecting a new hardware item to the device. If the 
device is connected first, it may be very difficult to 
complete the installation successfully. Always carefully 
follow the installation instructions that accompany the 
hardware or software. 
						

							97If Something Goes Wrong
If you need further assistance
❖Restart the Windows® operating system. Always restart 
the Windows® operating system after each installation, 
even if the installation utility does not prompt you to do 
so. This will ensure that the installation is completed, 
and will clean up anything that the installation utility left 
behind.
❖Do one installation at a time. If you have several new 
items to add to your device system, install just one at a 
time, creating restore points immediately before each 
successive installation. This will make it much easier to 
determine the origin of any new problems. For best 
results, follow this sequence:
1Back up critical data.
2Create a restore point.
3Install one item of hardware or software.
4Restart the Windows
® operating system.
5Use the new hardware or software for a while, noting 
any new problems. Make sure that your critical 
applications (email, business applications, etc.) are 
working correctly, and verify that important devices 
are still functioning.
6For each additional hardware or software item, 
repeat these steps, starting at step 1 if any of your 
critical data has changed, or starting at step 2 if no 
critical data has changed.
If you need further assistance
If you have followed the recommendations in this chapter 
and are still having problems, you may need additional 
technical assistance. 
Since some problems may be related to the operating 
system or the program you are using, it is important to 
investigate all sources.
❖Review the troubleshooting information in your operating 
system documentation.
❖If the problem occurs while you are running a program, 
consult the program’s documentation for 
troubleshooting suggestions. Contact the software 
company’s technical support group for their assistance.
