Hi all, Scenario and problem(s) below. The scenario: - 2 WRT54G (firmware: DD-WRT 22; versions: one WRT is v2.0, second is v2.2) with different channel settings: one has bssid 'b1' and second has bssid 'b2'. - No wireless security. - One Windows XP laptop (terminal - T) with cardbus wireless card. Association rules under the control of XP 'built-in' tool. Both APs ('b1' and 'b2') are added to 'automatic connection list'. - Initially 'T' is associated to 'b1'. Objective: - Force terminal 'T' to associate to 'b2'. The change must be forced 'from the network', ideally from telnet connections to WRTs. - The switching (handover) time should be resonable; target is less than 5 seconds. What was done so far: - Telnet connections to 'b1' and 'b2'. - On 'b1' I find the MAC of 'T' using: "wl assoclist". - 'b1' is changed to MAC filter deny mode: "wl macmode 1". - I add prevoiusly found MAC address to deny list: "wl mac <mac_addr>". - The 'T' is not 'kicked' as filter prevents from new association, it does not deassociate existing. (is this right?) - Next I kick the terminal using "wl deauthenticate <mac_address>" (is this the only way to kick the terminal from given AP?). Now "wl assoclist" shows that 'T' is not associated with 'b1' - switching starts. - About 15 seconds later the Windows XP realizes that connection is broken ('ping' status changes from 'timout' to 'hardware error'). - Second to few seconds later the WinXP finds 'b2' and associates automatically (as it is on 'automatic' list). Result: - Switching success, but time performance poor: 15-20 seconds. - Two cardbus cards tested. - Scenario with the same bssid results in 40-45 seconds initial delay. More questions: - Does "wl deauthenticate <mac_address>" cause a message sending to the terminal about 'kicking'? Or just it starts to ignore MAC frames from 'T' according to deny filter and not-associated status? - Is there a way to 'polite' deassociation so the WinXP would notice change faster? All other possbile 'b1' associated terminals must work without interrupt : ) - Is there a way to reduce the 15 seconds ignore/disconnect timer of WinXP built-in tool (regedit/hexedit)?
