Simple Ruby script to retrieve some useful Internet connexion statistics from a Siemens Gigaset sx762 modem/router. By default it only returns the Up- and Down-stream statistics, External IP & MAC addresses and Uptime, but if you pass the --verbose argument, you get the raw data back as well.

# Sample output (with faked IP/MAC addresses):
# Siemens Gigaset sx762 Statistics:
# ================================================================================
#     Up:   833 /   825 kbps [Attn: 408 dB / Noise: 56 dB / Pwr: 122 dBm]
#   Down:  1309 /  1316 kpbs [Attn: 602 dB / Noise: 61 dB / Pwr: 149 dBm]
# IP/MAC: 203.0.113.0 / 10:00:00:00:FF
# Uptime: 1061 minutes (~= 17.69 hours) (~= 0.74 days)
