View Full Version : [kubuntu] wireless connected but internet not recognized

September 3rd, 2009, 02:18 AM
Hi everyone, I'll warn you from the start I'm not exceptionally knowledgeable but I'll try and be as informative as I can to get help. Right now Knetwork Manger in Kubuntu 8.04 is showing that I'm connected to the wireless network in the apartment, but I can't access the internet. I can however connect with no problem in Windows so I don't believe I'm looking at a hardware issue.

I have a Gateway MT6828 laptop with an Intel Corporation PRO/Wireless 3945ABG Network Connection (rev 02)network controller which should be supported from the list I found.

iwconfig gave the following:

iwconfig wlan0
wlan0 IEEE 802.11g ESSID:"default" Nickname:""
Mode:Managed Frequency:2.437 GHz Access Point:
Bit Rate=11 Mb/s Tx-Power=27 dBm
Retry min limit:7 RTS thr: off Fragment thr=2346 B
Power Management: off
Link Quality=87/100 Signal level=-45 dBm Noise
level=-127 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid
Tx excessive retries:0 Invalid misc:0 Missed

From what I can tell, I am able to ping the IP address apparently assigned to the laptop, but I'm unable to ping a private ip (I tried the ubuntu forums as suggested in another thread). I get an "unreachable host" message.

Anyway, I'd appreciate any help/ideas I can get.

Can you post the output from
netstat -rn.

I'm sorry if that last bit was jumbled as I had trouble formatting it all in the message. Also, I'm really hoping the assistance can keep coming. I'd love to use linux full-time, but being able to connect to wireless is essential for me.

If you can ping your default gateway as well, the the problem may be DNS. Are you getting an IP address by DHCP or setting a static IP. DHCP should supply a DNS server. You need to configure a DNS server if the IP is static. Your DNS server will probably be

It should be set up to be DHCP.

I will try to ping the gateway as soon as I get the chance.

Thanks for the help thus far!
