This could be a firmware bug in the WLAN module as well... WIFI and Bluetooth use the same frequency spectrum of 2.4GHz. Bluetooth usually does not interfere with WIFIsince it uses very rapid channel switch (up to 1200 channel switches per second). But if you do an inquiry the Bluetooth module will almost broadcast inquiry packets on all of those channels almost at once to catch modules in its range. The inquiry scan algorithm is quite scary ;) So inquiry cause a lot of noise in the 2.4GHz spectrum. What could happen is that the WIFI firmware does not handle receive/transmit faults too well. So under certain circumstance while doing an inquiry a WIFI packet might get messed up quite badly without the radio detecting a signal drop (because in fact it had a good carrier all the time). Probably the same fault could be triggered with a high traffic WIFI cell... > Frantisek Cheers nils faerber - -- kernel concepts Tel: +49-271-771091-12 Dreisbachstr. 24 Fax: +49-271-771091-19 D-57250 Netphen Mob: +49-176-21024535 - -- -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFD6hQgJXeIURG1qHgRApkkAKCipsFYJBpX3OY7cn0AIFLJZJQfeQCfazYB J8gfZqs4TivArZZrVsCSrGA= =mtLz -----END PGP SIGNATURE-----
