For surfbeam 2+ users check out your new modem status page firmware UT2_188.8.131.52.10 http://192.168.100.1/ now seems to have some debug options and clear return link if your locked on a low symbol rate i guess?
my modem just stopped responding on me today. status page displayed but could not show any info such as SNR or even serial number. Blue light was on but modem just stopped responding. forced to powercycle.
