While most of us are using 802.11n devices or looking to replace them with 802.11n/ac devices, there are still some 802.11b clients wandering about. These old 802.11b devices can seriously impact the performance of our Wi-Fi networks on the 2.4 GHz band. How much? Let’s find out.
The internet is still expanding. Even more, we're facing a major explosion of the number of devices connected to the internet. The rise of smartphones, wearables and the Internet of Things are evolutions that will expand the number of connected devices to numbers unseen so far. The transition to IPv6 is inevitable, but why does it seem to take so much time?
This blog post shows how to configure the ISC DHCP server to provision cable modems. Cable modems use DHCP, the Dynamic Host Configuration Protocol, to obtain the basic connectivity settings, including a number of DOCSIS-specific DHCP options.
Cable modems get their operational parameters using config files. These config files define what the internet subscription will be, what additional services are activated and other configuration details. This blog post will get you started creating your own modem config file.
Wi-Fi has become the preferred technology for in-home connectivity, but sometimes it’s needed to connect a wired device (e.g. a printer) to a Wi-Fi network using a Wi-Fi bridge. In a wired world bridges are used very often and typically don’t cause much problems. In the Wi-Fi world the situation is slightly different, read on and find out why!
Rigorously testing a network device or distributed service requires complex, realistic network test environments. Linux Traffic Control (tc) with Network Emulation (netem) provides the building blocks to create an impairment node that simulates such networks. This final post of a three-part series shows how to set up an impairment node in practice.
