So it turns out that sometime in the past I removed the GPIO bits here and was going to move it into a module in order to save a little space. However, it turns out that was a mistake on this particular AP - it uses a pair of GPIO lines to control the two receive LNAs on the 2GHz radio and without them enabled the radio is a LOT DEAF. With this re-introduced (and some replacement userland tools to save space, *cough* cpio/libarchive) I can actually use these chipsets again as a 2G station. Without the LNA the AP was seeing a per-radio RSSI upstairs here of around 3-5dB, with the LNA on it's around 15dB, more than enough to actually use wifi upstairs and also in line with the other Atheros / Intel devices I have up here. Big oopsie to Adrian. Big, big oopsie. |
