At work I have a Cisco Aironet 1200 (nice AP) and moving my dell latitude D630 laptop beside it shows the same figures. Signal quality of around 50 % in the best case. Here is what I get with direct view of the AP : Cell 02 - Address: 00:0E:D7:78:C3:60 ESSID:"eduroam-web" Mode:Master Channel:6 Frequency:2.437 GHz (Channel 6) Quality=50/100 Signal level=-58 dBm Encryption key:off Bit Rates:1 Mb/s; 2 Mb/s; 5.5 Mb/s; 6 Mb/s; 9 Mb/s 11 Mb/s; 12 Mb/s; 18 Mb/s; 24 Mb/s; 36 Mb/s 48 Mb/s; 54 Mb/s Extra:tsf=000004116b6646b0 > Linux folks tends to break various things all the time ... Yes. That's why I don't like linux at all. > I dont belive that things are so much simple that changing only one bbp > all the time will fix signal sensitivity. > I do believe the same too. But I get lost because I'm not very used to wireless stuff.
