Can someone tell me what this script is trying to do? <Realtek driver dhcp script>

I've had off and on internet problems lately, and I think this might be the problem. I compiled some drivers I got from realtek, and it seems to be made for a different distro, as Slackware doesn't have a /etc/sysconfig/network-scripts/ directory.

Code:

#!/bin/bash

#cp ifcfg-ath0 /etc/sysconfig/network-scripts/
cp ifcfg-wlan0 /etc/sysconfig/network-scripts/

#dhclient ath0
dhclient wlan0

#var1=`ifconfig ath0 |awk '/inet/{print $2}'|awk -F: '{print $2}'`
var1=`ifconfig wlan0 |awk '/inet/{print $2}'|awk -F: '{print $2}'`

#var2=`ps aux|awk '/dhclient ath0/'|awk '$11!="awk"{print $2}'`
var2=`ps aux|awk '/dhclient wlan0/'|awk '$11!="awk"{print $2}'`

kill $var2

#rm -f /etc/sysconfig/network-scripts/ifcfg-ath0
rm -f /etc/sysconfig/network-scripts/ifcfg-wlan0

echo "get ip: $var1"

And here is the ifcfg-wlan0 file it is trying to copy.

Code:

#DHCP client
DEVICE=wlan0
BOOTPROTO=dhcp
ONBOOT=yes

Is there a slackware equvalent to the /etc/sysconfig/network-scripts/ directory where I can place this file? Or does slackware come with something that does what this script is trying to do? I ask because my wireless is so unstable that I can't use my laptop for any of my college work on campus.

The scripts /etc/rc.d/rc.inet1* do what you want. And for wireless devices /etc/rc.d/rc.wireless* helps configure it.

You should be using an in-kernel driver if at all possible. I believe your card will most likely have support. The best support comes in kernel 2.6.25 and later. If you want us to help you better, post your slackware version and kernel version.

Also, post the part of "lspci -v" that pertains to your network card.

I got help with this problem before, but the thread kind of died after I thought it was fixed.
I ended up reinstalling, because in the numerous fixes I tried I probably did more harm than good. Plus I am working on a page on the MSI Wind wiki on how to get it working.

This was my last thread:
http://www.linuxquestions.org/questi...twork.-666685/

I am currently running 12.1 with a 2.6.26.3 kernel with the realtek rtl8180 kernel drivers compiled as modules, and the realtek r8180 module compiled from source. I had to load the r8180 modules for wlan0 to appear on my system.
The r8180 modules are really buggy and compiled with a lot of errors. I was, on my previous install, able to connect to the internet for a short time, but later had no luck.
Would compiling the rtl8180 drivers INTO the kernel instead of as modules eliminate the need for the buggy compiled drivers?

Code:

02:00.0 Network controller: Realtek Semiconductor Co., Ltd. Unknown device 8199 (rev 22)
	Subsystem: Micro-Star International Co., Ltd. Unknown device 6894
	Flags: bus master, fast devsel, latency 0, IRQ 17
	I/O ports at b000 [size=256]
	Memory at dfc00000 (32-bit, non-prefetchable) [size=16K]
	Capabilities: [40] Power Management version 3
	Capabilities: [50] Message Signalled Interrupts: Mask- 64bit+ Queue=0/0 Enable-
	Capabilities: [70] Express Legacy Endpoint, MSI 00

	Capabilities: [140] Virtual Channel <?>
	Capabilities: [160] Device Serial Number 00-1d-92-c6-db-84-00-00
	Kernel driver in use: rtl8180
	Kernel modules: r8180

My goal is to get wifi to work. So far, my rc.wireless.conf is unchanged, i.e. it still has the ESSID="any" entry uncommented.
My rc.inet1.conf I went down to ifname[4]= and added some information.
IFNAME[4]="wlan0"
IPADDR[4]=""
NETMASK[4]=""
USE_DHCP[4]="yes"
WLAN_ESSID[4]="Univ-Hotspot"
WLAN_MODE[4]="Master"

All hotspots around campus use "Univ-Hotspot" as their essid. When I did manage to get it connected I remember that the mode was Master, so I put that in.
Is there any information, like where my laptop should look for a ip, that I can get from the campus computer department that might help me?
