D-Link card with a wireless PCMCIA card (SMC model 2853W 802.11g, 2.4
gH, 54 mbps). Unfortunately, I have so far been unable to connect my
laptop to the wireless LAN in the building. What I did to try to
establish a connection follows.
Iwconfig returned the following:
lo no wireless extensions.
irda0 no wireless extensions.
eth0 NOT READY! ESSID:off/any

Tx-Power=31 dBm Sensitivity=0/200

Tx excessive retries:0 Invalid misc:0 Missed beacon:0
sit0 no wireless extensions.
This looks like the card is recognized but I've never used a G card to
know if everything is ok. I've only used a orinoco (B card).
<snippage>
Examination of the messages which scrolled by while booting up revealed
the following, which by the way did not appear in the syslog file, or
show in dmesg:
Configuring network interfaces ... /etc/network/interfaces:10:
misplaced option
ifup: couldn't read interfaces file "/etc/network/interfaces"
Running "ifup eth0" returns the same, with the exception of the text
preceding the elipsis.
The file /etc/network/interfaces reads as follows:
1 # This file describes the network interfaces available on your system
2 # and how to activate them. For more information, see interfaces(5).
3
4 # The loopback network interface
5 auto lo
6 iface lo inet loopback
7
8 # The primary network interface
9 allow-hotplug eth0
10 address 127.0.0.1
11 netmask 255.0.0.0
Line 10 and 11 are not needed, and some bug report is needed, when
possible.
12 iface eth0 inet dhcp
13
14
15 auto eth0
When I commented out line 10, "ifup eth0" returned the same as above,
with number 11 replacing 10. When I commented out both lines 10 and 11,
"ifup eth0" tried to ping to the network. I did this test while
unconnected; I am sure that if I had been connected the pings would have
received a positive response.
As pinnedped said: some gui tools do strange thing with the
/etc/network/interfaces. So using the command line tools is the only
reliable way, at least in my experiece. ifconfig, iwconfig, ifup,ifdown
and the other iw-tools are what i use untill I find a GUI that works.
With the D-Link card installed ifconfig returns the following:
eth0 Link encap:Ethernet HWaddr 00:50:BA:78:00:6D
inet6 addr: fe80::250:baff:fe78:6d/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:33 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:0 (0.0 b) TX bytes:6344 (6.1 KiB)
Interrupt:10 Base address:0x300
This looks fine.
In any event, I can get the D-Link card to connect, even though I haveYou might want to try some 'testing' while we folks find a solution:
to open to my user before installing it. On the other hand I cannot
connect with either of the two wireless cards I tried.
The priority task is to get a wireless connection. I would certainly
appreciate all the help I can get to be able to do so. I would also
like to be able to switch from one card to the other without difficulty,
by obviating the problem mentioned in the proceeding paragraph.
1) see if you can ask the other person to try your wifi card in his/her
machine to see if that person can get a good result: the card is not
defective and works with a linux
2) see if the wifi owner would turn off secutiry (ASCII key) for a small
test to see if that help: the card works but the secuirty is not entered
correctly
