Hi guys,

I was hoping someone could help me. I have just moved house and I am quite honestly fed up using a wireless network on my PC. I lose connection constantly and the transfer rate always fluctuates.

In my new computer room (upstairs) there is an existing coax cable which runs from the living room (downstairs) which looks like it may have had cable TV or a cable modem connected to it. Is it possible to convert this to ethernet using some kind of converter?

There is also a phone socket in the computer room and one in the bedroom. Is it possible to plug an ehternet cable with some sort of converter as well or instead of?

I did consider homeplugs but I have read that they do not work well when plugged into an extension. I do not have an available plug for this.

My wireless router and internet connection via wireless router are both in the living room and I need to keep the wireless router here becuase I have a PS3, Wii and a media player which are all connected to it so moving the internet connection upstairs is not an option. I would really appreciate some help with this. Thanks!
 
its only something pathetic like 10meg or whatever

just use homeplug which is about 5 times that and uses the mains.
 
Thanks for the replies. Maybe I'm mis-understood a little. I am very much aware that coaxial is an old technology in terms of networking, but all I want to do is convert the coaxial signal to Ethernet. The signal can travel along electrical cables so there is no reason why it won't work across a coaxial cable with RJ45 connectors at the end. The actual cable is the standard used by NTL/Virgin medias so it is reosonably good quality. I was wondering what kind of speeds I would get and if it is possible?

For example, I found this:

You can't use that RJ45 to F plug adaptor.

Your lan ethernet requires 4 wires (2 pairs) one pair for Tx one pair for Rx.

The F plug is effectively only one pair (the earth outer shield and the signal core).

That plug will not modulate / convert / whatever your signal.

Can you not run a 10m cable up the wall, around the skirting etc?
 
Thanks Frank. That was the concern I had. I wasn't sure that the coax cable would have the wires for it :(

The living toom is directly below the computer room so a 10m ethernet cable should be more than enough. However, I am a bit uncertain about drilling through the floor/ceiling. Is this difficult to do? I would far rather have an ethernet cable directly connected than anything else.

thanks :)

go outside

you just need a big drill bit and a hole big enough to take the wire. then tack the cable to the wall on the outside to tidy up. Works a treat at my house and both the halls in the wall are on the floor behind curtains so you cant see them.
 
I don't think that is an option either :D

My missus would go nuts! She won't want me drilling through the wall that has just been painted and a cable showing at the front of the house bla bla bla. I will get it in the neck! The only option I have is through the floor or not at all. I don't know how difficult this will be though because I don't have clue what is under there or how to get through/around it. I suppose the only other medthod that is feasible is the homeplug setup. What kind of transfer rates should I get with this? The most I can get from my wireless network is about 17/18Mbits at the very most. I'd hope the homepluge setup will be much more than this if I decide to get it.

Thanks ;)
 
I use Netgear HDX 101's and the transfer rate (indicated) is never lower than 80Mb...well worth the price over wireless
 
If I was you vipergrm, I would go on a well known auction site and purchase a 20ft cat 5 patch lead, 2 x RJ45 connectors and boots and a RJ45 crimp tool.

Then securely attach the cat 5 to the end of the coax downstairs and pull the coax from upstairs till you get the cat 5.

Then put connectors on each end, clip/staple to wall/skirting board, job done.

i know how you feel, my missus is equally fussy. I was under strict instructions to use black patch leads. No cream / red / green etc for the outside of the house. I just tacked the black patch lead next to the black aerial lead so you cant see it.

As for the interior, i just drilled the hole behind the curtains and put the router behind the curtains as well. The patch lead just comes out the back of the router thats on the window ledge, behind the curtain, to the wall behind the curtain. Its then tacked outside and comes in under my desk in my study

Hiding it downstairs to please the missus is easy. You just need to worry about where it comes out. If you've got your own room or whatever she cant see, then you fine. If not, possibly consider moving your desk to the wall to hide the exit point ?
 
If you don't want to drill then get home plug though being honest popping a floor board and drilling two holes is pretty simple. If you use flat cat6 cable it's going to be barely noticeable.
 
Thanks guys for all your feedback. Much appreciated! I wish I'd thought of this BEFORE we got the new wooden floor down! I supposed I could just drill through it, but like I say, I'm just a bit worried that I might drill into something or perhaps I won't see the exit point! I might ask my friend who is a lot better at DIY than I am. The homeplug option sounds more and more intersting. If I get the kind of transfer rates that NickR is getting then I would be happy with this. I'll just have to make a wall plug available which I think I can manage. Has anyone tried the Solwise home plugs? They look like they'd do the job well. I can pick two of these up for the same price as one of the Netgears!
