Hi

I find myself unable to connect to internet through my new wireless card. I am able to get onto the local network, and I am able to ping all the servers I have tried - but I am unable to get any activity in any browser or mailprograms.

Can someone please tell me what I have overlooked or explain what I am doing wrong. I have read dozens of similar problems, but nothing seems to help.

Do note that my wireless modem is named "ra0". I use WEP-encryption, but get the same results without. My xDSL-modem router-function is turned off, and my wireless-router is 192.168.2.1.

The obvious thing I see is the /etc/resolv.conf file.

You have the IP address of your gateway here. It should be the IP addresses your ISP provides for DNS.

If you know what they are just edit the file as root and enter them. If you don't know what they are, contact your ISP and ask, or if you have another working machine, look there for them.

thanks - but that did not solve my problem.

I can ping the DNS nameserver (130.67.60.68) but not log onto port 53 (as I read somewhere I should try).

I am quite new to linux networking, so this may be caused by a simple mistake somewhere... but I need help finding out where.

Did you edit the resolv.conf file and enter 130.67.60.68 and try it? Having the IP address of your gateway won't get names resolved.

...I'm looking that new to linux?

Yes I did - but it seems like some GUI-tool reset the file, or is it the dhclient-script that create my problems?

I will try again and see, and your advice is really appriciated.

...and it's getting late over here, and I am still stuck.

I guess my configuration may not be quite OK, so if anyone cares to look at it:

ONBOOT=yes

BOOTPROTO=none
NETMASK=
DHCP_HOSTNAME=
IPADDR=192.168.102

Hi,

May be some firewall may be blocking it.
Try 'iptables -L" to find out whether the iptables rules are active and if yes
Try 'iptables -F' to flush out the rules

iptables -L tells (policy ACCEPT) everywhere, allthough there are nothing listed as target, prot, opt source or destination anywhere.

I use fedora core 3 and I am not perfectly sure I have the right driver for my wireless network-card. Could that be the case, that the driver is inncorect?

(CNET CWP-854 card - RT61_Linux_STA_Drv1.0.4.0 driver)

By the way, I do not initialize this card or its setup at startup, but run a script manually. Would that matter?

Hi,

Can you please try the telnet <google.com> 80 ?
Try the tcpdump command to find out the packets moving in and out through port 80

Good Luck

God Loves you

hi,i'm new to this forum, but i have the same problems last night here. i plugged my ethernet cable and configure but then i can't connect to the internet.

The name server ( DNS ) was right ( check it in /etc/resolv.conf ) , my IP , gateway, etc was right but i still cannot connect thought i could ping google. For almost 1 hour i tried to reconfigure my networking, then i read something. It was said that the firefox could not locate any proxy at all, so i tried to go to YaST ( i used SuSE linux 10.0 ) and try change the proxy setting so that the proxy automatically detect proxy configuration instead connect to the internet directly.

i don't know if it's work for you, but it works on my lappy.

thanks -- cmiiw

Thankyou for your advices. I however gave up and installed fedora core 5, and my problem has not reoccured.

So, I have "solved" my problem, allthough that solution was really what I tried to avoid.
