Please log in for more thread options I want to install a cable modem but I dont want to have the modem in close proximity of my TV. So I guess I need a long coaxial cable to maximize the distance between the socket in my wall and the modem, to which I want to connect my router as an access point for 2-3 PCs. Will I have losses on bandwidth if I take a cable of 10m? I dont want to use any "bridge solution" such as WLAN due to its inherent instability. Best regards Nima | |||||||||||||

> 10 meters of coax OR ethernet won't affect your speed at all. 10 meters of ethernet isn't going to trouble anyone, it's true in almost all cases. However, I'm afraid this is simply not true for all cases with co-ax. You can degrade the cable modem upstream path in a hurry with the wrong grade of cable, poor connectors or both in addition to the loss on 30 additional feet of marginal co-ax cable. Or in my case given the length of my outdoor drop, another 30 feet would make things simply not work here. Best Regards, -- Todd H. http://www.toddh.net/ | |||||||||||||

In general, you're far better off making that run with ethernet cable verus co-ax. Leave the modem near the jack where teh installer tested and verified signal levels and cabled it with a cable they made from the proper grade of co-ax. From there, run any ole standard ethernet cable to wherever you'd like to place your router. You might get away with adding 10m of off the shelf cable to your modem drop, then again you might put yourself on the ragged edge of upstream gain, cause a lot of packet loss and generally make your life hell. Make the run in ethernet, and you're far less likely to have trouble. Best Regards, -- Todd H. http://www.toddh.net/ | |||||||||||||

The first problem with your suggestion of putting the cablemodem at the wall-socket is that whilst seated at the computer you then can't see the indicator lights -- which are, after all, put on the device for a reason. In a perfect world, the cablemodem wouldn't have those lights but ... I live on the fourth floor of a seven-storey building. The cable service comes from under the street into the basement and is then distributed throughout the building. In my living room is the jack -- 'where the installer tested and verified signal levels' ??? HA! You must be joking. In any event, I have a five-metre cable running from the jack to the first television (and the first splitter), then another five-metre coax to the second television (and splitter) and finally a third five-metre coax to the cablemodem, on the shelf above my primary computer and next to the router. Everything works fine! Once in a rare while the 'net goes down, but that's when the ISP has issues at the head end. And when that occurs, the lights on the cablemodem tell me that it's lost sync, without me having to scratch my head, get up and go out to the wall-socket to wonder what's going on. To the OP: with a decent quality cable, a run of 10 metre coax will in all likelihood pose no problem at all. There will (probably*) be no 'loss of bandwidth'. ( * I obviously can't make you any promises. As I said at the beginning, there is always a small chance -- I'd put it at 1-2% -- that it won't work the way you want, for whatever reason. But, hey, that's a reasonable level of 'risk', eh? And if you get unlucky, the solution is simple enough: _then_ you put the cablemodem at the wall-socket and run a 10-metre Cat.6 ethernet cable to your router.) cheers, Henry | |||||||||||||
