| 748308 | 2009-02-16 07:55:00 | I was under the impression that Cat5e and Cat6 did Gigabit, not the 100M as stated in a previous post? I think they ment 100M as being 100 metres not speed :D That's I mean in my post anyway. And yes CAT5e & CAT6 do gigabit speeds if wired correctly. It uses all 4 pairs of wires as opposed to 10/100 which only uses 2 pairs. |

| 748309 | 2009-02-16 09:37:00 | 80M will be fine, get cat6 and you'll get less interference, probably worth it at that distance as you're nearing the maximum. Cat5 works at gigabit :D I just upgraded my home LAN and its all wired with cat5, works fine at gigabit speeds. The person I bought the switch from told me that it won't work without cat6, he was wrong. The theoretical maximum for a home broadband is about 4000 computers, limited by NAT :) |

| 748310 | 2009-02-16 10:29:00 | Aaah, thanks for clarifying, after re-reading I see the post probably did mean distance rather than speed. WarNox, where does 4000 come from? |

| 748312 | 2009-02-16 13:19:00 | yeah I meant 100Metres, and fair call with the 90M - pays to allow for someone plugging something different in, also it is the MAX total distance including all cords. All 3 support Gigabit speeds, CAT5e and CAT6 are just a little better designed and salesman like to sell things ( or to be nice they also like to play it safe ). I get tired of hearing people say you "NEED" a certain cable type - anything CAT5 and above will work, for long runs or heavy interference areas the higher standards perform better but aren't strictly required. Over short distances say < 20M you can get away with almost anything. Gigabit is a really tricky design, the 4 pairs have different amounts of twist and therefore end up different lengths, because gigabit breaks the single up and sends in both directions up / down all 4 pairs it has to compensate for this difference in delay when it reassenbles the data - amazing stuff. |

| 748313 | 2009-02-16 20:21:00 | Yeah I wouldnt have guessed 4000 either ... Many routers have a limit to the number of concurrent connections they can have open from what I understand, but I dont believe 4000 is a hard-and-fast limit of NAT? I could be wrong though :D |

| 748314 | 2009-02-17 09:31:00 | Yeah got that wrong lol I'll go find out where I read it. | WarNox (8772) | ||
| 748315 | 2009-02-17 09:35:00 | O yep sorry, went back and re-read where the 4000 came from. Here it is: Port numbers are encoded in 16 bits. The total number of internal addresses that can be translated to one external address could theoretically be as high as 65,536 per IP address. However, realistically, the number of internal addresses that can be assigned a single IP address is around 4,000. So maybe I am correct... ? |

| 748316 | 2009-02-17 11:55:00 | Where did you find that? Im not sure I understand the context fully :-/ | Chilling_Silence (9) | ||

The theoretical maximum for a home broadband is about 4000 computers, limited by NAT :) Yeah, I think going with cat6 will be better in the long run, in case we want to make use of gigabit ethernet later on. That and the quality requirements for cat6 cable are (I assume, since it needs to transfer data at gigabit speeds) more stringent to reduce signal interference. So, no kinks or severe right-angle bends in the cable? Strange, I never knew that a network connection could be affected that way. Just like a garden hose, eh? |
