network-manager: bandwidth of 54 Mb/s wireless networks shown as 62 Mb/s

[jcfp]

When placing the mouse over a wireless network listed in knetworkmanager, it will show a popup with a number of network details. One of those is named "bandwidth", indicating the maximum bandwidth of the particualr wireless network.

This indicator wrongly shows bandwidth as 62 Mb/s for all networks, instead of 54 Mb/s. See screenshot.
The same happens with nm-tool, so this is probably a network-manager problem.

In case that matters, wireless netcard used is this atheros/madwifi based:

Same here. with ipw2200.

[Aldoo (aldo-public)]

True also with ipw3945, on at least two laptops I know of.
Though iwconfig does not make the mistake and actually shows 54 Mb/s.

Well, it does not seem to be driver-dependant, is it ?

[jcfp (jcfp)]

Seems driver/hardware-independent indeed then; wlanconfig, iwlist, etc all correctly list networks as 54mbit.

[jcfp (jcfp)]

nm-tool (part of network-manager) also indicates 62 Mb/s, so the origins of this bug might well ly deeper than knetworkmanager (which is just a "KDE frontend for NetworkManager"). Adjusting bug report accordingly.

Still exists in kubuntu gutsy tribe 4

[Olivier (olivier-lacroix)]

Still exists in Kubuntu Beta

[Alexander Sack (asac)]

does this still happen in intrepid for you?

[Alexander Sack (asac)]

no answer. assuming its fixed.
