====== How to check the received signal level of a 3G modem ======

To find out the modem signal reception level, open the Network Setup -> Status -> System Log page:

{{ network:sys_log.png?direct&800 |}}

In the appeared log you need to find the AT commands and the answer to the CSQ command:

{{ network:sys_log_csq.png?direct&800 |}}

For example: **+CSQ: 23,99^M**

The first number in this answer (23) is the __signal quality__.

^Value	^RSSI dBm	^Quality	^
|2 .. 9  |-109 .. -95 |	Bad	|
|10 ..14 |-93 .. - 85 |	Normal	|
|15 ..19 |-83 .. -75 |	Good	|
|20 .. 30 |-73 .. -53 |	Excellent	|
