100 ft Ethernet outside & underground

[ErnieM]

I need to run about 100 feet of Ethernet cable from my garage to my house. My home office is in my unattached garage, so my Comcast cable comes in at that point.

But, with my recent purchase of an Oppo 93, I would love to get streaming and other internet capabilities to my HT setup in my house.

This will require running an Ethernet cable of about 100 ft from the cable modem in the garage to the house. About 10 ft of this would be buried underground.

I chatted with Monoprice and they tell me they don’t sell any cable rated for being buried.

I’m thinking I could buy one of their regular cables and for the underground portion I could enclose it in some plastic conduit that I’d buy at my local Lowe’s or Home Depot.

Any suggestions?

You could try Wireless N with a high gain omni directional (7dB antenna).

The 93 has wireless N I believe (or it can be purchased from Oppo).

Bury the cable in conduit, that will be the best and cheapest solution.

I thought for a sec about same thing Jin proposes, but then I realized that you probably want internet in other places in house - WiFi would not be ideal for all that, especially if in farther places from your office.

TLS is right - just get plastic conduit.

I believe you're also hitting the edge of an ethernet run without a repeater at 100 feet. Of course, if it works, it works. Good luck and I hope that it works!

Probably cat6 cable would be a better choice - it has better isolation

Being underground, that's a moot point unless it's running parallel and extremely close to power lines.

Conduit is the only way to go.

I'm pretty sure it's around 100 Meters or roughly 320-ft.
Haven't done it in over four years, (memories fading fast) as we started getting getting busier we stopped doing limited energy stuff. I called in one of my AT&T buddies that retired to run all that.

328 feet with Ethernet is the spec. But with the modern tranceivers on cards like 3Com it's more like 400 ft.

A high gain omni and 100 foot span? Should hit pretty good throughput. They can always try it and return it.

I would hate to trench all that (either by hand or rent a ditch witch) to find out later an N Access Point with good antenna would have given me 200Mbps through put at the house.

It sounded like the total run was 100ft but the buried conduit portion was only around 10ft.

Ok, I re-read the OP. I wonder what the point to point distance is? I still say a high gain antenna would work out...

Thanks for everyone's responses. I am considering the suggestions to get a Wireless N unit with high gain antenna. Any suggestions of specific units?

My cable comes into my garage and I've positioned the cable modem as close to the house as possible. Distance from the cable modem to my Oppo 93 as the "bird" flies is probably 65 to 70 feet.

Here's a schematic of my situation:



However, I am still more leaning towards running a Cat6 cable. The part that would need to be buried is about 10 feet from the garage to our rear deck (not shown in the drawing). From there I'd run it outside the house over to the wall just behind my home theatre setup and drill a hole into the living room from outside.

Any further thoughts from the community are highly appreciated!

Get a MIMO N router from BB. I believe you have 30 days to return it for a full refund. It's $79.

I don't get the reluctance / hesitance to put in a zero effort solution and test out. This will take two hours including the trip to BB.

Jinjuku,

My hesitation arises from having tried this once before with a Hawking wireless-G range extender HWUG1. I set it up inside our house and it worked for a while, but not very well, then finally bit the dust. I do recognize that N is a lot more advanced that G.

After reading your latest reply to me, I will seriously consider going this route with the D-Link unit.

With the D-Link unit you recommend, I hope you don't mind me asking what is a beginner's question: Do I need to hard-wire the unit to my Comcast cable modem (CG814WGv2), or can I set it up inside the house, 30 feet away from the Comcast unit in the garage?

If the D-Link is in the house, should I consider buying a better antenna for the Comcast unit?

Thanks again.

It's going to go Comcast modem to the D-Link. Get it mounted up high as possible. Disable the radio on the Netgear. You will use the D-Link in AP mode.

If you get it drop me a PM with your phone number. You can go to fixme.it, install the plug-in and get me a client ID. I can take over the connected computer and config the D-link for you.

If using FireFox for fixme.it you will need to restart the browser. Let me know when you want to schedule a time.

Last fall I buried a ~200ft of Cat5 up to the hill in my back yard for an antenna so I could receive a signal from a Wireless internet service provider.

Ran 3/4" PVC electrical conduit. 10' is $1.44 from Lowes.
Conduit

Now gone through a whole winter/spring/many rain storms with no problems.

And in actuality I never filled the ditch in till this spring so the conduit is was exposed all winter.

I have since filled it in but need to bring in more dirt to finish it off.

Burying 10' would be very easy.

 

[ErnieM]

I thank everyone who responded. I especially thank jinjuku for the generous offer to help me!

I'll give an update as to how things proceed.
