Troubleshooting
4.4 No Internet Access
If you cannot access the Internet from any of your local devices, take the
following actions to identify and solve the problem:
• On the Internet page, make sure that the Link status is
Up and that an
IP address is defined.
• Make sure that the GSM/UMTS antenna is properly connected and
tightened to the Ericsson W21 antenna connector.
• Check the Alarm indicator on the front panel of the Ericsson W21 unit.
If it is red, see the information in the Alarms section on the Overview
page.
• On the Internet page, check that the PIN field is filled in and that there
is no error message beside this field. If there is a message saying
Insert SIM, verify that a valid SIM card is correctly inserted and then
retype the PIN code on the Internet page. If the message says
Set
PIN
, only retype the PIN code. If the SIM blocked message is
displayed, the PUK is required to unblock the card.
• On the Internet page, check that the APN is correctly entered in the
APN (3G) and APN (2G) fields according to the information from your
service provider.
• On the Internet page, verify that the mobile network signal quality
indicator displays at least one bar. If not, move the Ericsson W21 or
attach an external antenna (indoor window or outdoor roof mounted).
External antennas are available as accessories to the Ericsson W21.
• Make sure that the LAN or WLAN connection is established. For
troubleshooting, see section
– No LAN Connection or 4.7 4.8 – No
Wireless LAN Connection.
4.5 Slow or Intermittent Internet Connection
If your Internet connection is unacceptable slow or regularly dropping, take
the following actions to identify and solve the problem:
• On the Internet page, verify that the Connection is
HSDPA or UMTS. If
not, move the Ericsson W21 or attach an external antenna (indoor
window or outdoor roof mounted). External antennas are available as
accessories to the Ericsson W21. Verify with your operator that HSDPA
is available.
