If you think that wording is dodgy, you try getting your head round Block ACK :-) wpa_supplicant supports setting scan_ssid=1 in the network block to make it scan with a specific SSID in the probe requests, thus getting responses only from the AP which has that SSID (and spotting the "hidden" ones that won't respond unless you do this). /usr/share/doc/wpa_supplicant-0.7.3/wpa_supplicant.conf on my F15 system warns that this will add latency to scanning, which I simply don't believe. In a target-poor environment you will send more probe requests, but people typically don't have so many networks configured that this matters. In a target-rich environment it cuts down the storm of probe responses and thus improves things - you get APs on the far edge of range colliding with their probe responses and increasing the probability that the one you really wanted to see didn't get a look-in before the scanning station gave up and moved to the next channel. I think scan_ssid=1 should be the default, to be honest. If your network config is in the text file you can probably fix this. I've got a suspicion that you don't get to use wpa_supplicant.conf with NetworkManager though. I don't have any NetworkManager-enabled systems to check with though; my boxes are either servers or I need NM to stay out of the way for other reasons. -- But while the ant gathered food, the grasshopper contracted to a point on a manifold that was NOT a 3-sphere... -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
