Is there a cabled equivalent of a wireless repeater?
Posted on 2009-05-01
I have an 80 ft. Ethernet cable going from my router through the attic to another room, where I wired an RJ45 wall outlet. If I plug a computer in, I have flawless Internet and network performance. However, when plug in an XBox 360 instead, chances are less than 50% that it will work without playing with configuration. I tried plugging in a switch so that I could leave both of them plugged into the switch all of the time, but neither will work.
However, putting the switch between my router and my main computer (which is on the same desk, so 10 ft. of cable) exhibits no problem. A friend tested the switch at work (on short cables) and could see multiple IP addresses through the switch.
As background, my network is configured like this:
Linksys WRT54G 100 MBps router
cat 5e cabling
livingroom computer 192.168.1.51
gameroom computer 192.168.1.52
work notebook computer DHCP (192.168.1.100-192.168.1.105)
All of this works fine without the switch. With that being the case, and the switch working in 2 out of 3 tests, is my 80 ft. cable the problem? I can't see how it could be miswired if I can use the Internet and my LAN reliably, so is the distance somehow a problem? If so, how can I improve the speed/performance over this length without upgrading to a Wireless N broadband router and cat 6 cable?
