How do I feed an ethernet cable through a doorway without damaging the door or wall?

You can buy flat Ethernet cables. I'm betting you could get one under the door and still allow it to be closed. Another option is a powerline Ethernet adapter. This is a set of modules that plug into ...

Wiring Ethernet through Telephone Cable

Nope! Plain Old Telephone Service (POTS) jacks were usually daisy chained as you describe. Ethernet requires a "home run" from each jack to a modem, router or switch. Also, it's probably cat-...

Can I run 300 ft of cat6 cable, with male connectors on each end, under house to other side?

There are two issues, one trivially easy, one a big "maybe": Don't Use a Patch Cable Don't use a patch cable. Period. The reason is that patch cable ends break. Oh, I'll just crimp on ...

Should I dig a separate trench for CAT5e wire to shed?

Same trench is fine. Use conduit, you may want to upgrade it later without re-trenching. Keep some space between the conduits, vertically, horizontally, or both. Interference between 60 Hz power and ...

Can an ethernet cable look OK to a cheap cable tester but still have a problem?

Yes, absolutely. However, if it was working (at high speed) previously, then stopped, that is a little strange, but not unheard of either. If the cable is old and has been run over by office chairs or ...

Can I run 300 ft of cat6 cable, with male connectors on each end, under house to other side?
