Just purchased a Wavlink WL-WN530HA3 dual band router, and getting broadband cable service installed. From my understanding, the tech will install an ethernet connection, in which I plug into the router, use the ethernet cable to connect router via LAN port to my notebook computer (Sony VPCS132GXB) running Windows 7 Pro. Once set up, all should be fine (I hope), but I don't want to leave route on 24/7 due to power concerns or security issues. Is it okay to power router off every evening? Or just power off when not at home?
