Hello...is it possible to get the values of Signal strength, noise and SNR without weblogin to monitor these values via external Tools like Nagios?

Since Pharos Control (an administrative controller for CPEs) can manage to read those values without logging into the web UI, any other utility should be able to do this also. You just have to find out how Pharos Control achieves this (probably using SNMP).

As a last resort, you could use ssh to grab those values using the CLI. Since this device is running Linux, be somewhat creative:

[CODE]
$ ssh admin@192.168.1.254 iwconfig ath0
admin@192.168.1.254's password:
ath0 IEEE 802.11na ESSID:"XXXXXXXXXXX" Nickname:"RFS-1"
Mode:Master Frequency:5.64 GHz Access Point: 98:DE:D0:12:34:56
Bit Rate:300 Mb/s Tx-Power=17 dBm
RTS thr=2346 B Fragment thr:off
Encryption key:none Security mode:open
Power Management:off
Link Quality=94/94 Signal level=-36 dBm Noise level=-95 dBm
Rx invalid nwid:22856 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0
[/CODE]

There you have it. Calculate the SNR from signal and noise levels. You could use an expect(1) script to automate the ssh dialog asking for the password.
