Alternative networking over cable and power line

0 Comment

Well I installed both of these to test them. The first is an actiontec moca 2.5 adapter set that provides 2.5Gbps over cable to 16 devices. This network we cut off from the main cable internet connection. That’s because we have docsis 3.1 and moca 2.5 frequencies conflict so rather figure out how to change…

Ok two quick notes, this week has been mainly about broken network issues. Or rather putting as much care in the home network as that has really become mission critical. So three lessons: Wow, the setup for the Dream Machine and the Amplifi are even easier than for the Dream Machine Pro. Really hats off…

This is a very nice piece of hardware that complements the Time Capsule mainly. You can use it to add a printer to your network (in essence, it converts a USB printer into a network printer), you can use it as an…

Print Servers

I actually tried a print server about five years ago and it worked terribly, but now I’m willing to give it another shot as I really want our Canon i9900 to work on network. If you can believe it, here is actually an entire web site that covers just Printer servers called “Print-server-reviews.com”:http://print-servers-reviews.com. The main…

NTP Servers

0 Comment

If you have DD-WRT or some other devices that need a time server to get the correct time, “NTP”:http://ntp.isc.org/bin/view/Servers/WebHome#Browsing_the_Lists can help. There is a list of servers that provide the exact time free for network devices. If your device can take a DNS name, then the “pool”:http://ntp.isc.org/bin/view/Servers/NTPPoolServers servers are great since they give you a…

I’ve been using v2.70 for a while, but it doesn’t work with the more advanced encryption schemes. In particularly, it really only works with WEP 128 bit. However, there have been some releases since then so that now with “2.75”:http://www.dslreports.com/forum/remark,16808179~mode=flat I’ve been able to get WPA with AES working. This is all greek to many…

Another Wireless Setup issue

I someday wish that someone would solve this, but fresh on leaving work, I got to spend an evening fixing another network here in China. This time I had a good education in Chinese user interfaces and thanks to “dltool”:http://dltool.sourceforge.net, it was easy to figure out the interface and learn some Chinese words for things…

Wifi Debugging

Well, the network at Qiming doesn’t seem to work that well, we have a low end all Linksys system with two access points and a LAN router, so how to diagnose it. “Tech-faq.com”:http://www.tech-faq.com/wi-fi-software-tools.shtml has a very good list of tools and at the top is my old favorite “Netstumbler”:http://www.stumbler.net/ this tool only works with Prism…
