I've seen mention of cards capable of receiving around -80 dBm down to -97 dBm. I think around -90 dBm would be a good value there... I also don't think I've ever seen a card (out of my stack of 6 and a few more from friends and coworkers) that's been able to get above -20 dBm, so that might be a good starter value. We could also adjust this stuff on the fly (at least the upper bound here) and maybe move that down as low as -30dBm over time, though that gets more complicated. I guess the answer would be "fix the driver" if people complained enough. Sounds like a good idea though. Thanks for the tip.
