Parameter Setting via the Web Interface – Chapter 5
The same applies to the column
Channel/Frequency
if the AP works on a channel
that is not included, for example, by specifying a channel list under Configuration
Wireless
Roaming.
The
Extra Information
column contains the following information:
Country setting (DE)
Number of clients / channel utilization (5 / 2%)
If available: Transmission power limitation (17dBm)
Roaming operations a/b – a= failed operations b= successful operations
Noise level (-95dBm). This value + SNR gives the measured signal level.
(-95 + 48 = -47dBm)
5.1.8 HTTPS Webinterface
The websites of the radio modem can also be accessed via HTTPS (Hypertext Trans
-
fer Protocol Secure). This enables an encrypted data exchange between radio mo
-
dem and web browser. The HTTPS server on a configurable TCP port (default 443)
is activated under
Admin
(see section 5.3.1 on page 44).
5.1.9 Storage Status Information
Figure 32
Web interface: Storage Status Information
A USB memory stick can be connected to the radio modem, which can be used to
store debug messages or recordings on the WLAN or LAN interfaces. When such a
USB memory stick is plugged in, the status of this memory is displayed at the bot
-
tom of the home page.
Before removing the memory stick, the user should disconnect the memory from
the system using the
Unmount
function to ensure that the contents remain consis
-
tent. In particular, if the USB stick is formatted as a FAT file system, errors in the file
system of the USB stick may occur when switching off without first unmounting.
If the USB stick is used to record debug messages and/or (W)LAN recordings (see
chapter 9 on page 77), the USB stick should be formatted with the EXT4 file system.
This file system is more robust in terms of data consistency when the radio modem
is suddenly switched on and off.
In the
Extra Information
column, additional information is displayed when the cur
-
sor is placed over the individual data. So you can additionally display the list of
neighboring APs (see Figure 31).
For this access, the radio modem uses a self-generated server certificate that must
be confirmed in the web browser during the first connection. The browser usually
reports an insecure connection or certificate problems. This message usually
offers a way to continue to the site nonetheless. The browser's confirmation mes
-
sage varies depending on the browser type, e.g.: Advanced - add exception, con
-
tinue, load website nonetheless, ...
All existing files on the USB stick are deleted during formatting!
