Slackware 10.1 with USB network adaptor

Hi Slackers :)

I am in need of some help. I'm trying to go fully wireless in my house and get my PC up and running with a USB wireless adaptor (it's a D-Link DWL-G122). I got the driver installed using ndiswrapper, and "ndiswrapper -l" does show me the driver loaded into memory. Next I did:

Code:

# modprobe ndiswrapper # ifconfig eth0 down # ifconfig eth1 down # iwconfig wlan0 essid cupotea # iwconfig wlan0 mode managed # ifconfig wlan0 192.168.2.1 netmask 255.255.255.0 # route add default gw 192.168.2.1 netmask 255.255.255.0 # ifconfig wlan0 up

I don't get any errors along the way.

The problem I have is I can only see my PC's and the router on my internal network. I can ping these PC's and the router and I can visit my router homepage at 192.168.2.1 in a browser and it works OK. If I try to visit any external sites it says [sitename] could not be found. Please check the name and try again .... almost as if it can't do DNS lookups? How do I tell it to use my router as the DNS server?

This is the output of "route"

Code:

# route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface default * 255.255.255.0 UG 0 0 0 wlan0 192.168.2.0 * 255.255.255.0 U 0 0 0 wlan0 loopback * 255.0.0.0 U 0 0 0 lo

Also here is the output of ifconfig / iwconfig:

Code:

I can't think of anything I've missed ... where am I going wrong? :?

You need to change the setting in your "iwconfig". Currently, the mode is set to "Managed", which means it is set as an intranet. To change that, just do:

Code:

iwconfig wlan0 mode ad-hoc

I'm pretty sure you're going to have to restart the connection after you get that set.

Are you sure?

I have another slackbox in my house with a Linksys wireless PCI card which is configured as 'mode managed', and it works ok on the Internet ...

Well, when I was getting my wireless set, every document I read said to change the mode to ad-hoc to be able to access the rest of the internet. I got the same problem as you when I was setting mine up, then I changed to ad-hoc and BAM! Hello internet!

Just tried ad-hoc mode and it doesn't work. I did a bit of googling and ad-hoc mode seems to be for a "network composed of only one cell and without Access Point".

Anything else I can try?

I can ping anything on my internal network, but just tried pinging the external IP address of my router and it says "connect: Network is unreachable"

One more thing, I can't shut down my computer either. When I do "shutdown -h now" the screen fills up with this:

ndiswrapper (wrap_reset_port:1040): reset failed: -22
ndiswrapper (wrap_reset_port:1040): reset failed: -22
ndiswrapper (wrap_reset_port:1040): reset failed: -22
ndiswrapper (wrap_reset_port:1040): reset failed: -22
etc etc ....

I can't imagine where bidi got his info. Ad-hoc is a wireless network type that does not require a router/ap. Since you have an access point, managed is fine.

So, you can ping the router. Good for you. Can you ping internet sites? Type:
ping 4.2.2.2
This is level 3's dns server. If you get a reply, good. If you don't, check your routes. Type:
route, or /sbin/route
You should have one that says something like default 192.168.2.1 If you don't, type as root:
route add default gw 192.168.2.1

Now type "ping 4.2.2.2". Hopefully, this works now.

dns is in /etc/resolv.conf, or maybe /etc/dhcpd/resolv.conf. If you can't find it, do:
find /etc | grep resolv.conf

resolv.conf should have an entry that looks like this, so you can ping/visit google and such:

nameserver 192.168.2.1
also perfectly good is:
nameserver 4.2.2.2
You ISP should have a dns server too.

Hope that helps.
