Troubleshooting Problems with Wireless LAN Connections
Factors such as electromagnetic interference can result in disconnection, recording or playback 
stopping, and other similar problems. In such a case, please try to resolve the problem using the 
following countermeasures. 
NOTE
The term “access point” below refers to any device that can function as a router.
Countermeasure
Connection via 
an access point 
(Connection G)
Connection not 
via an access 
point 
(Connection H)
Applicable situations
Change the Wi-Fi channel being 
used.
(Refer to the manual 
that came with your 
access point for 
details regarding Wi-Fi 
channels.)
(Refer to the Owner’s 
Manual or Reference 
Manual that came with 
your instrument for 
details regarding Wi-Fi 
channels.)
When, in addition to the access point to 
which the instrument and the iPhone/iPad 
are connected, other access points are 
available (multiple networks are displayed 
on the iPhone/iPad Wi-Fi settings screen).
Stop using Wi-Fi on other 
devices connected to the same 
access point.
When watching video or downloading data 
on other devices connected to the same 
network overloads the access point and 
causes the wireless speed to drop.
Change to Connection H 
(connection not via an access 
point).
When multiple devices are connected to 
the same network. The access point is 
overloaded and the wireless speed has 
dropped.
Turn off any electrical products 
generating electromagnetic 
interference.
When electromagnetic waves used by 
wireless devices such as portable 
telephones, microwave ovens, and 
Bluetooth devices are causing 
interference.
Move closer to the access point.
When the network signal strength shown 
by the instrument’s Wi-Fi settings page or 
iOS is low.
Move the instrument slightly 
away from the access point.
When the instrument is right beside the 
access point, and the strength of the 
electromagnetic waves is actually making 
it difficult to receive data. 
Turn off Bluetooth on iOS.
Bluetooth can generate electromagnetic 
interference even when not being used to 
connect to other devices.
Update iOS to the latest version.
In certain cases, communication 
performance may be improved by 
updating iOS. 
Restart the iOS device.
In certain cases, devices may connect 
after being reset.
Restart the access point.
In certain cases, devices may connect to 
an access point when it is restarted.
Update the access point’s 
firmware to the newest version.
In certain cases, updating the firmware 
may improve communication performance. 
Replace the access point.
When using an access point employing old 
specifications such as IEEE802.11b.
