iPhone 3G Wifi Speed on Zyxel HW660 Router

More a  reminder for me than a real post, but if anyone suffers from the fairly common "iPhone 3G/3Gs slow wifi" issues (see here, here and here), follow the instructions in the third link and things should come right. I don't claim to really understand what RTS/CTS means (Zyxel's definitions are here) but having recently swapped my router at home for a Zyxel HW-660-D1 router (thanks Mike), I was suffering from incredibly slow wifi on my iPhone (all other devices were fine, just the iPhone's were having problems). I spent ages trawling the interweb and eventually improved things by changing these advanced settings on the router:

  1. Disabled 802.11G+ (and just using 802.11G instead)
  2. Changed to RTS/CTS Threshold to 2432
  3. Changed the fragmentation threshold to 2432
Although it's not blisteringly fast, I can at least listen to BBC Radio Cumbria using WunderRadio without it buffering all the time.
