I have reproduced this problem with Intel Corporation PRO/Wireless 2200BG (ipw2200) on OpenSuSE 11.1: linux-w8vm:/usr/src/packages/SOURCES # cat /proc/net/wireless Inter-| sta-| Quality | Discarded packets | Missed | WE face | tus | link level noise | nwid crypt frag retry misc | beacon | 22 eth1: 0000 73. -55. -91. 0 13120 0 174 0 1 The same problem seems to be in the System Monitor (ksysguard) in KDE3 and KDE4: The metric localhost->Network->Interfaces->eth1->wifi->signal and noise are in dBm but are also in the range of <-350. Debian has fixed the problem in wavemon. I have attached a patch that fixed the problem in Debian. I have tested it and it works against wavemon-0.4.0b-273.11 -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
