Never heard of this site? Well, unless you are into alternative router operating systems, you would probably have never heard of it. Yet it is one of the most popular sites for networking people. Literally people who are into the business of routers. Anyway, DD-WRT is an open source alternative to those firmwares which are found in some of the consumer routers like those from Linksys, D-Link and so on. What they do is to replace the default firmware with their open source firmware which have tons of cool features not found in the default ones. Pretty cool eh? And interestingly, some of these features can only be found in high end enterprise routers which cost like 10 times more. Go ahead, check whether your router is supported and have some fun with your router. But only if you have some knowledge about routers. This is not meant for the faint hearted. I have been using alternative firmwares for my routers (I purchase only those supported ones) for years already. One of which lasted me 5 years without any problems.

Do you need networking supplies from a reliable supplier? And I am talking about critical pieces of equipment, something which you don't want to fail when you need it. Just look at the consumer grade models that we have in the market right now. They are relatively cheap I have to admit, but do you honestly think that they are that reliable? I remember my first few routers breaking down after a few months. Worse, there was one thing had intermittent problems, causing my little network to slow down when I am doing work. Can be frustrating for the home user. Just imagine what will happen if you backend fails for thousands of staff. Nobody gets any work done. Aruba Networks offers routers, Access points, network management software and other networking hardware and software for the corporate environment. Even for mobile devices, they have management software for them. This way, you can easily allow mobile devices like Android Smartphones or iPhones to your network without compromising the security.

No matter what you say, Windows is still the most common operating system among users. Yes, we know that they do have problems, especially in the beginning when networking became popular but I think Microsoft has more or less solved many of the problems that plagued them in the beginning. And setting up Windows is a breeze, compared to the various other operating systems out there. Not to mention, most computer manufacturers and retailers usually sells their notebooks and desktop PCs with Windows already pre-installed. So yes, knowing a little about Windows Networking is very important. Check out the latest news, reviews, hardware and software to hit the Windows scene. Although one might think that setting up a windows network environment is easy, it still requires knowledge and up-to-date information to accomplish that. Also check out their list of free tools to help make your networking capabilities better. Oh before I forget, check out the latest security updates and news so as not to miss out on any critical patches that is needed to ensure your network is safe.
