Hi, Wifi is not something I consider myself an expert upon. I understand the security problems with WEP, WPS, WPA and WPA2 fairly well, and I've read some docs on fragmentation, RTS thresholds, and channel width. I don't consider myself a newbie here either. Try as I might, I just can't seem to get decent performance out of my home network. It's a 802.11n network, theoretically 300 mbit/s, however testing with iperf between a Linux wireless laptop and a wired linux server results in 60-70 mbits reported in either direction. I tried fiddling with a few options on the router, such as: * disabling a/b/g support. (no effect) * disabling pre-spec-N support. (no effect) * lowering RTS threshold slightly (lower throughput) * lowering fragment threshold (no effect at small changes; perf slightly increases (~5mbit) as fragments decrease for a while, then after a point (around ~2000 bytes) performance just drops as you decrease size.) * WMM no-ack mode (totally wrecked performance) I'm using a Broadcom chipset in the laptop, which seems to have reasonable Linux support. I'm using the opensource brcmsmac driver on a 3.2.0 kernel. The AP is an Asus RT-N15, which also runs Linux, although I'm still on the vendors firmware. So, no matter what I've done, I can't get more than 75 mbits, and on default settings its more like 65 mbits between these two Linux devices. However a friend with an Apple Mac laptop and an Apple airport AP can push about 200 mbit/s according to iperf! So.. I just wondered if anyone has some hints about how to improve wifi performance? I also wondered what sort of bitrates you see? And if someone is getting good speeds, can you report your hardware (incl. chipset) and configuration options? thanks! Toby
