Wi-Fi 802.11ac

Let’s talk about wireless. The new specification has been passed, making different use of both 2.4 and 5 GHz bands. Some devices clearly are easier than others to modify and change using Linux distributions such as OpenWRT among others. Device manufacturers change hardware (chipsets and other things) without changing version numbers, helping lead to further confusion about what a new router/access point really can do. The number of radios and antennas in each device can make a big difference in performance. Manufacturers also constantly change models and price points. It’s hard to keep up with all the changes to commonly available Wi-Fi brand network adapters (built in or USB) and access points. Software defined radio (making hardware changes less necessary) is still far too expensive for most applications. People most interested in radio often become amateur radio operators by passing tests to get privileges to legally experiment with radio in the US and elsewhere.

How are the Wi-Fi chipsets you own supported by the Linux Kernel? What access points do you use and what would you now recommend to friends? What do you think about the so called Super Wi-Fi proposal by the FCC? How do you feel the SF Digital Inclusion (or other municipal network efforts) are going?

We meet on the second and fourth Sundays of each month from noon to three in Berkeley near the Downtown Berkeley BART station near the corner of University & Shattuck. We hope you join us at Bobby G’s Pizzeria and/or join the discussion on our email list.
