06 | Keysight | Access Your 34972A Wirelessly with a Sapido Mobile Router - Technical Overview
Method 2 – Sapido mobile router in
Wi-Fi AP mode
This is a slightly more complicated wireless connection method, but
it provides additional benefits. Your computer communicates with
a central access point. The 34972A also communicates with the
same central access point through the mobile router. This method
requires the availability of an additional WLAN (a central access
point on a wireless network), but as a result, you will be able to
access other Web sites and instruments with your computer if the
WLAN provides those capabilities. Other computers will be able to
communicate wirelessly with the 34972A simultaneously with your
computer.
The following part 1 procedure is based on the Sapido mobile router
Wi-Fi AP mode starting from the factory default settings. You can
restore all of the factory default settings in one of two ways: with
the mobile router powered, either press and hold (for 10 seconds,
then release) the recessed RESET button (not the WPS button)
on the front of the mobile router, or, if you can access the mobile
router's built-in Web server, click System Management > Profiles
Save, then Reset. Following a reset, wait for about 90 seconds for
the mobile router to reboot.
Wi-Fi AP mode steps, part 1:
configure mobile router
You need to perform the steps in part 1 only once to configure the
mobile router's Wi-Fi AP mode. The configuration is saved even with
power removed. Afterwards, you will be able to use your 34972A
wirelessly by following the steps in part 2.
1. Set the Sapido mobile router mode switch
–With power to the mobile router removed, set the mode switch
on the back of the router to W (Wi-Fi AP mode).
2. Wire mobile router connections
–To the LAN port, connect an Ethernet (RJ-45) cable.
–Connect the other end of the Ethernet
cable to the computer's LAN port.
–Connect power to the mobile router to
turn it on (see measurement tip on page 2
on powering your mobile router).
3. Configure mobile router
–Before you proceed, make sure the mobile
router has been powered up in Wi-Fi AP
mode, as described in the previous two
steps.
–Temporarily disable your computer's wire-
less connection to avoid conflicts between
the computer's wireless and wired-LAN
connections. Wait for the mobile router to
assign an IP address to your computer.
–Open a Web browser. Connect to the mobile router's built-in
Web server by entering "192.168.1.254" as the URL. The Sapi-
do mobile router's login screen should appear.
–Log in using "admin" as both the user name and password. These
are the default settings; once you are logged in, you can change
them if necessary. The Network Config screen should appear.
–If the wireless network to which you want to connect has
security, configure the mobile router with the security settings.
Click Wireless, then Security on the left side of the screen and
provide the required information. Do not be concerned about
the Select SSID field for now; leave it set to the default setting.
Be sure to click Apply Change and wait for the router to recon-
figure itself (about 25 seconds).
–Click Wireless > Site Survey. A list of available wireless net-
works should appear, as shown in Figure 5. If needed, you can
refresh the list by clicking Refresh. Find the one to which you
would like to connect the 34972A and select the radio button
next to it. Click Connect. You should see a screen showing
"Connect successfully!". Click OK. The wireless network you
chose along with its security configuration, if any, will be saved
in the mobile router for Wi-Fi AP mode even if you remove
power from it.
–At this point, if desired (not necessary), you can use the mobile
router as a wireless adapter for your computer if you disconnect
(for at least 30 seconds) and reconnect the LAN cable. The
mobile router will assign a new IP address to your computer.
After your computer is assigned a new IP address by the router,
you should be able to connect to the internet (if available from
the wireless network to which you are connected) with the
computer. The wireless connection path is from your computer,
through the Ethernet cable to your mobile router, to your wire-
less network without turning on any built-in wireless adapters
in your computer. If you want to, you can confirm the mobile
router is connected and working properly by accessing a Web
site. Now that the mobile router is configured properly, it can
be used to provide wireless connectivity for the 34972A.
–Disconnect the Ethernet cable from the computer. (In part 2,
step 3, you will connect it to the 34972A.)
Figure 5: In Wi-Fi AP mode, the Sapido mobile router shows a list of available wireless networks. Select the
one to which you want to connect your 34972A by clicking the radio button next to it.
