What's the best to CAT6 wire the house? I ran CAT6 cable from one single wireless router location to each room. I have 4-port 802.11n router but I am going to buy 8-port router as I need more then 4 port. The router is in the office which is in one corner of the house the house is 70' long), I don't know if wireless signal is strong enough to reach every part of the house. Should I install wireless access points for phones Wi-Fi connections? If so, where in the house and how many should I install? Anything else I need to add or take into account?
The CAT 6 standard usually calls for 22ga conductors vs 24ga in Cat 5e. CAT also uses all 8 conductors vs 4 of the 8 being used in Cat5e and earlier. As pointed out, termination is important with as little untwisted pair wire lenghts as possible.
When I built my house 6 years ago, Cat 5e was it. I would go with Cat6 today. However, I do get 1GB connections on many of the cable runs, especially the shorter runs. I have 20 wired jacks in my house include one behind each wall TV mounting location along with the cable and AC power connection. I use a Netgear 16 port GB switch behind my Linksys GB router to give me the wired port support I need.
The ideal location for your wireless router location is near the center of the house in an elevated location when prossible. Even a 2nd floor installtion will be better. Line of sight positioning to your most commonly used locations is best because going through walls knocks the signal strenght down quit a bit.
Your 70 ft on wireless is pushing it even in open air. If you have any wall to go through with the signal, you are likely not going to be able to get a reliable connection. The higher the elevation for your N wireless router, the better
