It is a common practice for service companies like hotels, resorts and restaurants to be providing WiFi Internet access to its customers. However, there is a common mistake also for such companies. The WiFi network is on the same network segment as the office computers. This is a security issue because now you are allowing strangers to have local network access to your computers. In order to avoid the issue where the WiFi users can access your local network, the office network must be on a separate network segment, with its own router and firewall blocking any unauthorized access from outside the network. Another concern with sharing Internet access to customers is that your own Internet access might become slower also because of the increased download and upload activity. There are firewall devices available on the market that allows you to segment the network into two or more subnets. You can put the office network on one subnet and the customer WiFi access on the other. Then on the firewall, define the rules such that incoming traffic from the customer subnet is blocked if it is going to the office subnetwork. With a little change on the network configuration, one can increase the computer network significantly. With the constant threat of malicious Internet activity, it is important for business owners to secure their computer network to protect its business...

by: Jerome Auza Before I had setup my experimental solar power system, a power interruption like that scheduled on March 9, 2014 would mean that we need to purchase gasoline worth around Php800.00 to keep the office network running. It’s probably more expensive these days with the gasoline hitting the Php60.00/liter mark. I checked my solar system today and I have 57% charged batteries. The system seemed to have charged slowly the past two days. I expected close to 100% charge after two days with lots of sunshine. This is something for investigation later. However, at this time, what I need to know is how long can I run the network without resorting to the generators. If the sun is out most of the day during the power interruption, I would expect to be able to run the network for at least 10 hours. To be sure, I plan to turn off some of the non-essential equipment like that powering up the LAN of the office since there will be nobody working. My wife who runs a maternity clinic at Talibon, Bohol has her own solar system also and is currently fully charged and should enable her to run the most important equipment at her clinic during the power interruption. Services like ultrasound and fetal montiring for her patients at St. Gerald’s Maternity and Wellness Clinic should continue even without electricity. I have one 300W solar panel coming soon so the articles in the coming weeks should be interesting since I can start configuring the system to run the office network 24/7 on solar power. I’m still a long...
