View Full Version : [ubuntu] local name in iwconf not matching

August 5th, 2008, 05:10 AM
Hi all,

This maybe a silly question but I'm having a problem with wireless speed on my local home network and with trying to trouble shoot the problem I ran into a wierd situation. When I listed the iwconfig on a mythbuntu frontend computer using a MSI PC60G wireless NIC PCI card using a RT61 PCI driver, the results are -

lo no wireless extensions.

wmaster0 no wireless extensions.

wlan0 IEEE 802.11g ESSID:"renewabletechnology"
Mode:Managed Frequency:2.412 GHz Access Point: 00:1D:7E:CD:49:5C
Bit Rate=9 Mb/s Tx-Power=27 dBm
Retry min limit:7 RTS thr: off Fragment thr=2346 B
Link Quality=36/100 Signal level=-40 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0
As you see the logical name for my wireless interface is wlan0. When I list the lshw -C network for the same computer, I get this -

description: Wireless interface
product: RT2561/RT61 802.11g PCI
vendor: RaLink
physical id: 5
bus info: pci@0000:01:05.0
logical name: wmaster0
version: 00
serial: 00:1d:92:12:c5:cb
width: 32 bits
clock: 33MHz
capabilities: bus_master cap_list logical ethernet physical wireless
configuration: broadcast=yes driver=rt61pci ip= latency=64 module=rt61pci multicast=yes wireless=IEEE 802.11g
As you can see the logical name is listed as wmaster0. Should this be the same in iwconf and lshw? Can anyone tell me if this is correct or if I have a problem to solve?

Any help would be appreciated.

You may want to have a look within:

The bold is my file (yours may differ).

These are the persistent rules generated for persistent network device naming.

I had to rename mine as such:

# PCI device 0x14e4:0x4311 (ndiswrapper)
SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="00:1a:73:b5:7e:d1", ATTRS{type
}=="1", NAME="wlan0"

Hope this helps you get started......

Hi cdtech,

Thanks for the response. I checked the file you referred to and the logical name is the same as when I look at ifconfig, so I guess everything is fine, Thanks for the info and help,
