Summary: Spurious disassociations in prismGT STA <-> prism2.5 AP
setup
Product: prim54
Version: 1.0.2.2
Platform: ia32
OS/Version: Linux 2.6
Status: NEW
Severity: normal
Priority: P2
Component: Firmware
AssignedTo: prism54-devel@prism54.org
ReportedBy: vda@port.imtp.ilyichevsk.odessa.ua
prism54 firmware/driver spuriously disassociate
at low to medium signal levels even under light traffic.
Under heavy traffic this happens even at the very good
signal levels.
Looks like STA slips into 'try to find better AP' mode
far too easy. I tend to blame firmware. Mine is 1.0.4.3
Typical AP log:
