Why more WiFi?

The UK has finally ratified the 802.11n standard for WiFi at last. Although we've had '802.11n-ready' kit on the market for a fair while, it hasn't been official as yet.

I can only hope people in stores will be able to explain what people are buying. I say this because of what happened the last time we had anything as '(standard)-ready', which was with high definition televisions. It wasn't pretty.

Essentially, the problem then was that there were too many versions of the technology around. People weren't clear what they were buying and the technical standard changed while they were buying. So things that were HD-ready weren't true HD, which really confused the hell out of people.

I hope the same doesn't happen with 802.11n. In theory it should be straightforward as people won't have had conflicting standards thrown at them. But I'm willing to bet nobody'll trust it at first.

Good points from about the “‑ready” confusion, and a neat reminder from that better Wi‑Fi is ultimately about making devices easier to use. A few practical notes that weren’t in the thread and will help anyone buying or troubleshooting 802.11n kit.

First, what n actually brings (in plain terms): multiple antennas (MIMO) so a box can send/receive several streams at once, wider channel options (40 MHz bonding) for higher peak throughput, and protocol improvements (aggregation, better modulation) that improve range and reliability compared with 802.11g. That said, theoretical peak rates are rarely seen in real homes — real gains show up in faster file transfers across your LAN and more stable streaming to multiple devices, not necessarily a faster web page if your ISP link is the bottleneck.

Practical buying and setup tips: prefer devices that show Wi‑Fi Alliance certification rather than “n‑ready”; pick dual‑band kit (2.4 and 5 GHz) if you can; use 5 GHz when you want less interference and don’t need long range; keep firmware and client drivers up to date for best interoperability; enable WPA2 for security. Beware mixed‑mode networks: if you leave older b/g clients active, the access point will use protection mechanisms that slow the whole network — switch to “n‑only” where feasible.

If performance isn’t what you expected, check driver/firmware versions, confirm both AP and client are set to the same channel width (20/40), try the 5 GHz band, and move the router clear of metal/other electronics. In short: the standard fixes several real-world problems, but buying wisely and configuring for your environment matters more than marketing labels.
