Hello lads 'n lasses,

I currently run my computer's internet access via a cable modem, with a 20k service. I'm awaiting delivery of my 'new build' computer and intended/hoped to be able to run both computers from the same modem.

However, I've somewhat belatedly realised that my 256 modem only has one ethernet port, so I thought to buy an adaptor or hub(?) to enable me to connect up both ethernet cables, saving me money on having a buy a second modem from the cable company (as I'm a really tight old git... ). Unless of course, you chaps know of, or can think of a better, more innovative alternative?

I'd appreciate your thoughts/observations/advice as there appears to be an abundance of products available, but I'm not sure which would be the best choice. I don't want anything 'spectacular' with all manner of fancy 'bells and whistles' necessarily, just something that, because of splitting the power level, allows me to connect the two computers without losing too much power to each of them. Could a cable booster alleviate this...if there is such a thing that is?

Many thanks in anticipation of some quality/helpful advice.

Tim. ('Clubofjacks')

Do hope you have a high speed modem, as the numbers you supplied are a tad low. In this case, you can only have/use one modem. What you need is to purchase a router, which will split (open more ports) the signal for you.

Cable connects to modem, then Ethernet to router, and Ethernet to several computers (unless you decide to get a wireless router and signal is transmitter to several computers), Mindblower!

Mindblower is right on the mark.

You need a router/switch. Here's the Newegg page. If you can't order from them you can use it for research. - http://www.newegg.com/Store/SubCategory ... ed-Routers

Cable modem>Ethernet>Router>Ethernet to each computer. The router also gives the added benefit of creating a home network so files are available on either computer.

Thank you Mindblower and Dave,

I already have a wireless router and bought it originally intending to use it to provide my second (new) computer's internet access.

The problem I have is, because of where the new computer needs to be situated, the signal strength from the router is apparently somewhat 'patchy' and because of it, insufficient, because of my home having very thick stone walls. I hope, based on what you've both said, that connecting one end of my 60 foot ethernet cable into the router and the other end into the new computer it should work well?

Correct me if I'm wrong, but to ensure I've got this right it's...

Cable>Modem>short ethernet>router>ethernet to computer 1+ 60ft ethernet into new computer?

I'm also hoping because computer 1 is Vista and Computer 2 is Windows 7 there shouldn't be any problem with networking files? Sorry if my 'old dog' technical ignorance generates raucous laughter about the silliness of my questions.

Tim.

Right you are Clubofjacks. The Ethernet cable from what I've been told can be several hundred feet long. What you receive, input signal wise, can be almost limitless (mixed bag), providing you do not exceed your built-in limits. There are boosters to send wireless signals further - but you can only connect one high speed modem to phone or Cable line, Mindblower!

Hi Tim,

[quote:2wk1pw9s]connecting one end of my 60 foot ethernet cable into the router and the other end into the new computer it should work well?[/quote:2wk1pw9s]
Yep, should be no problems dong it that way. Some connections are sensitive to cable length and will suffer signal degradation once over a certain distance (e.g. phone cable to modem) but it is my understanding that an Ethernet cable (from router to tower/computer) can be as long as you need and will still work perfectly over long distances.

Yes, that's it mate....spot on.

Should be no problems networking Vista and Windows 7. To save a lot of typing have a look here: http://www.howtogeek.com/howto/9040/how ... and-vista/

If you run into any hitches (with networking) just post about them here Tim and we shall do our best to help you sort it out.

Not at all mate. Quite the opposite in fact. Your questions are all relevant and most sensible.

It's a nice little project you are undertaking Tim, would be appreciated if you keep us informed of your progress.

Cheers.....Jim

In a perfect world Ethernet is good to 100 meters, or 328 feet. 60 feet is nothing with quality cable (cat5E or cat6).

I defer to the master.....

Absolutely no sarcasm intended. Dave is indeed a sheer genius with this stuff....(well, with most stuff really).

Hello again lads,

ozbloke, perhaps what we need on this site when we all 'defer to the master' is a "We're not worthy" emoticon.

Seriously though lads, your collective, experienced and knowledgeable imput is once again very much appreciated.

To let you know, this new computer is intended for my son and our foster children to complete internet based homework tasks, as well, no doubt, to engage in irritating levels of 'text speak' via the 'dubious delights' of facebook etc.

I will write a little report when the computer arrives as to how successful the connection has turned out.

Thanks again.

Tim.

Tim, what a great suggestion.

Dave, can you please supply us with a "we're not worthy emoticon" ASAP.....thank you!
