CAT5 UTP outside, my equipment gets zapped often.

So here's the problem. I have some UTP CAT5 running down, under, some vinyl siding from 2nd story to walkout basement of my home. I did this maybe 5 years ago and the CAT5 itself is holding up fine. Though, once in awhile, that CAT5 seems to pickup some stray lightning and kill a network switch, a IPTV box, and access point, so far.

In hindsight I should have run shielded and grounded one end to the waterpipe in my wiring closest that it's going to now. No, I rather not re-do it now with STP. Sure, that would be the easy answer. You have no idea what a pain it was to run this.

Does anyone think grounding (one side of cable) of the two unused pairs would help as a poor-man's shield? Has anyone done this? I'm not using POE. I can go ahead and not crimp those grounded pairs on the other side of the cable. I'd think any stray electrical build-up would be so inclined to take that path rather than kill my equipment. I currently do have a CAT5 surge protector on order that I'll install as well.

Thanks in advance.

you need lightning blocks those other pairs are just for emi over the cable which should always be used. my question is why are you running that cat up there? no wifi?


im not sure why you are runing the cat. Is your switch up stairs or in the basement? you could always use t2 waps and bridge them then hook your switch into that over using the cat but will sacrifice some performance

I'm not buying the other pairs are for EMI since they are used in PoE applications. My broadband service enters the basement, I have router, switch and server there. The 2nd floor I have another switch (fed from my outside CAT5) and then feeding multiple computers, TV's and so on. I have AT&T uverse which is a IPTV technology for my TV's. My TV set top boxes are fed via CAT5. I've tried a wifi bridge to the 2nd floor before (802.11n) and no way can it handle the bandwidth needed for all that I have going on.

Really just wondering what other people have done with UTP in outdoor applications. Like I had mentioned, I have a Ethernet surge protector on order.

Well gigabit uses all 4 pairs 10/100 does not it uses only 2 and thats is used for emi. I can show you in my net+ book.


As far as the only other option besides pulling a cat up there you can try something like this. http://www.amazon.com/gp/aw/d/B001AGM2VI

Some go up to 300mbps. Which i think is about max

You're correct on gigabit Ethernet using all 4 pairs. I'm not trying to run that however. I've yet to see a decent review on the powerline Ethernet adapters. Seems I really just need to run some cable down a cold air return or something and just forget trying to do it outside. I was hoping to find an easy route which obviously is not working our for me....so it goes.
