The Update Gateway page allows you to update the iConnect625W router's firmware and
configuration files.
To upload and download configuration files and firmware for your iConnect625W router
using
Update Gateway
, follow the steps below.
Step 1
:
From the
Tools
tab, click the
Update Gateway
link provided. The following
page appears:
Step 2:
Upload Firmware:
click the
Browse
button and select the location of the
firmware file to be uploaded, e.g.
'C:\Program Files\firmware v1.1'.
The file size should not exceed 3.5MB as specified on the Update Gateway
screen.
Step 3:
Click the
Update Gateway
button. The status of the uploading appears at the
bottom of the page. When the upload is completed, the iConnect625W router
reboots and you are prompted to log in again.

Ping Test
Once the iConnect625W router has been configured, it is a good idea to make sure that
you can ping the network. If you can ping an IP on the WAN side successfully, you should
be able to surf the Internet.
To perform a
Ping Test
, follow the steps below.
Step 1
:
From the
Tools
tab, click the
Ping Test
link provided. The following page
appears:
Step 2:
Change or leave the default settings of the following fields:
±
Enter the IP Address to Ping
field where default setting is
192.168.1.254.
This is the WAN-side IP address that you want to ping;
±
Packet Size
field where the default settings is
32
bytes. You can define the
packet size of the ping test;
±
Number of Echo Requests
field where the default settings is
3.
You can
define how many times the IP address will be pinged.
Step 3:
Click the
Test
button. The ping results are displayed in the box shown on the
page. If the ping test was successful, it means that the TCP/IP protocol is up
and running. If the ping test failed, you should restart the iConnect625W router.

Modem Test
The Modem Test feature is used to check the connectivity to the WAN. There are four
test types: F4 End, F4 Seg, F5 End, F5 Seg. Each of these types may take a few
seconds to complete. In order for the test to work, at least one WAN connection must be
configured and a valid DSL link is available. If the DSL link is not connected, the test will
fail.
The OAM (operation, administration and maintenance) loopback cells (F4/F5) are used to
verify the connection between the iConnect625W and the ATM network.
For the
iConnect625W, OAM loopback provides a valuable tool for diagnosing problems with the
DSL line. The two main purposes of the F4/F5 cells are:
±
Fault Management (detection and notification);
±
Loopback testing and link integrity
The ATM OAM is divided into several levels:
±
F4: VP Level
o
OAM information flows between network elements (NEs) used within
virtual paths to report an unavailable path or virtual path (VP) that cannot
be guaranteed. Segment flows are processed, as well as end-to-end
flows that terminate in the management processor.
±
F5: VC Level
o
OAM information flows between network elements (NEs) used within
virtual connections to report degraded virtual channel (VC) performance
such as late arriving cells, lost cells and cell insertion problems.
Segment flows are processed, as well as end-to-end flows that terminate
in the management processor.
Both F4 and F5 flows can be configured as one of the test types:
±
Segment
o
This test verifies that ATM continuity exists between the virtual channel
link segments from the iConnect625W router to the DSL provider
network (typically this is a DSLAM at the DSL provider site). DSLAM
stands for
Digital Subscriber Line Access Multiplexer.
±
End-to-End
o
This test verifies ATM continuity exists of the virtual channel link with the
ATM endpoint, such as a remote broadband access router located at the
DSL provider or ISP site.
Before you attempt any of these modem tests, ensure the following:
±
Your DSL Provider / ISP supports them;
±
You have a valid DSL link.
To perform a modem test, follow the steps below.
