802.11G health issue and home network cabling question

Could you please give me some examples? Thanks!

Nope, but others have and its trivial to google for.

That's an interesting opinion about needing wall stud attachment and may even be code in some places but it's not a majority view. Even among "pros".

Home Depot and Lowes both now carry the "orange" old work boxes for doing this without stud attachment. They work quite well and unless you mess up, no sheet rock repair required.

You make mistakes? Say it ain't so, Joe (err Jeff)

fundamentalism, fundamentally wrong.

Everytime the wife gives me grief about layin round getting nothing done, I blame the wireless and its effects on health.

I prefer "Jack D. Repair". I once made some business cards with that name on it. I didn't work as expected because too many people didn't understand the pun.

I recently installed an extra PVC pipe on the wall behind my relay rack full of radio junk to the roof. My other conduits were maxed out full of coax cable, CAT5, fiber, RG-6/u, rotator cable, wx station cable, signal wire, etc. The standard procedure is measure twice, cut once. That works fine, but not while getting interrupted every few minutes by obnoxious friends with computah problems. I missed drilling by about 1/4" into the wall. Argh. I had planned to use a 1 1/2" PVC pipe, but that won't work partially buried into the wall. So, I dug out the jig saw, enlarged the hole to fit a 2" PVC pipe, mounted the pipe, and patched the mistake with spackle, plastic wood, and roofing tar. Nobody will ever know unless I show them.

Like I said... I hide my mistakes.

To err is human and I need to reassure myself occasionally.

And ya cut it again and it was still too short... heh heh heh

The network card LAN lights lite up, and no shorts and good continuity in all the pairs. It was a 150 ft run. I suppose one could try to duplicate it with some very very tight skinny nylon wire ties and see what happens.

Nevertheless, that was indeed an interesting you tried.

Ok. If you had continuity (and not split pairs), then all that's left is crosstalk and reflections.

Pass. My hands were a wreck after about 200 staples. I couldn't play piano for 2 days. If I'm going to do nylon cable stranglers, then I'll see if I can borrow a pneumatic cable tie tool.

I got inspired by TV's "Myth Busters". I like to do technical urban legend type of tests. I didn't do these photos but they show that the common guesswork for losses in coax adapters at 2.4GHz is way too high. All those connectors only contributed 2.1dB of loss at 2.4GHz or about 0.09dB per connector pair. |

No insult, but are you sure you didn't split pairs? That usually gives lights & continuity, but no signal.

Other than that, I've heard _uniform_ stapling can create a "notch filter".

Heavens no..no insult taken, but always good to offer another suggestion. Anyway, pairs were good.

I'm reaching way back into some distant memories for this and I may be wrong but given that 300MHz is a 1m wavelength I think you in effect made a STP cable. You'd want to space out the staples much more than 1" or 2" for this test.

Some time ago I thought about testing 10baseT with a common mode
