Our hotspot has 'a lot of bluetooth going on' on it. Today after installing compat-wireless modules with still no luck as a last resort i decided to turn of BT and take out BT dongles from hotspot's USB HUB. Magically BB started showing pages on atheros. Doe's anyone know a solution for that (except not using WiFi or BT:) ) ? I guess I blamed ath5k driver without a reason, sorry for that. Hm, is there BT coexistance support for ath5k? Adrian ___ ath5k-devel mailing list ath5k-devel@lists.ath5k.org https://lists.ath5k.org/mailman/listinfo/ath5k-devel

No, but my understanding is that BT coex support is only for co-located devices, so unless the phone is using ath5k it wouldn't help here. I guess one could try using a different channel for the AP or fiddling with the transmit power in hopes of making the channel avoidance on the BT device work better, but I don't know if there's anything more that could be done. -- Bob Copeland %% www.bobcopeland.com ___ ath5k-devel mailing list ath5k-devel@lists.ath5k.org https://lists.ath5k.org/mailman/listinfo/ath5k-devel

From my understanding, bluetooth coexistance is so devices don't tx/rx interfere with each other. Ie, what you don't want is the wifi device RX'ing whilst the bluetooth device is TX'ing; you don't want the wifi device TX'ing whilst the bluetooth device is also TX'ing. I could be off though, I haven't yet written any btcoex code for FreeBSD (as I just don't currently have any hardware that supports it.) http://linuxwireless.org/en/users/Documentation/Bluetooth-coexistence I guess one could try using a different channel for the AP or fiddling with the transmit power in hopes of making the channel avoidance on the BT device work better, but I don't know if there's anything more that could be done. There's mention on that page of bluetooth devices being able to be told about BT channel ranges which they shouldn't use; you could then program the ap and BT device to use non-conflicting channel ranges. How this is done though is an exercise left to the reader. Also, I've no idea if the AR5212 era devices support bluetooth coexistance. I'd have to do some further digging into the historical archives to check. FreeBSD (which uses the older HAL based code) certainly doesn't have btcoex code for the chipsets.
