Hi folks, having many reliability problems with cable modem service, and I'm pretty sure it's a coax wiring problem. I've spent *weeks* on this infernal mess and eliminated everything but the internal house coax. We *must* have reliable broadband, my wife is in an online accelerated Master's program. Digital TV cable working fine, no dropouts on HD channels, etc., but internet cuts out, even tried switching TV and cable lines and eliminating cable box. Literally everything else including outdoor cable to company's distro box has been replaced with same results; great speed tests when connection works, electricals look great on the Cable tech's measuring gear, then modem disconnects hours later at no particular time of day. Not a cooling or power delivery issue. THREE modems now... two Mot SB 6120 and a Mot 6141, all exhibiting similar behavior. Router and other coax wires replaced, similar behavior. We use one cable modem at a time (duh) and one router (Linksys WRT54GL) at a time--router tests and behavior always nominal. We are about to replace the RG6 cable, so I'm looking for suggestions on: 1) Connectors: does anybody bother to use (75-Ohm characteristic Z version) BNCs or other high-quality connector types on their wall outlets? I think F connectors are the spawn of Satan, sorry for the profanity. If there is a BNC kit that crimps easily to the Coax, I'll use it. Don't want to solder, very hard for my disabled body to bend low for that delicate work. 2) Wire: Anybody use over-specced wire? I have a very conscientious electrician who uses radius-protectors for coax where it is stapled to walls, but I don't want to mess with my bloody coax ever again. 3) Anybody use a powered coax distribution splitter? I have a single passive splitter in the system, thinking of insertion losses. All thoughts welcome, thank you.
