Hi OCAU members, Apparently Telstra are coming to my house tomorrow to " fix a issue with port one blocking " whatever that means? recently my speed started dropping down to 6mb where before it use to sync at 20mb. I believe my modem statistics are pretty good I never have drop outs. SNR Margin = 13.6 Attenuation = 23.5 Output Power = 19 Attainable Rate = 21076 current sync speed = 6138 so does anyone have any experience with this? why are telstra coming to my house?
