Wireless connected but not web browsing
Hi
I have ubuntu 10.10. I am connected through wireless (connection established) but I can not browse the internet on firefox. It works with out a problem when connected through the wire. |
Verify your DNS servers, firewall, proxy....
If you have a firewall, you need to change eth0 to wlan0 Please post the output from Code:
ping 212.100.160.51 |
Hi
Thank you for your message: Here is the output of the 2 commands. Please, let me know if I made something wrong. Also, could you tell me how I can check whether I have a firewall installed? best wishes stephan@stephan-1015PEM:~$ ping 212.100.160.51 PING 212.100.160.51 (212.100.160.51) 56(84) bytes of data. 64

Are you using wep or wpa wireless connections? If so, try to connect without encryption and see how that works.
Some wireless hardware can be stubborn with wpa. For instance, I have been able to connect to wpa wireless and not go anywhere with rt2500usb. Open a terminal and issue the following commands: sudo ifconfig sudo iwconfig These commands will give the experts a little more to go on. |
The output from ping is when you are connected with the wireless, right?
I means the connection is working. Could you please post the error message when you try to surf? Did you configured any proxy in your browser? Try to disable ipv6 in your browser http://thedaneshproject.com/posts/di...-in-firefox-3/ Kind regards |

You probably don't have the chassis software--firmware--properly loaded in the wireless card. Usually if you can get the card to work with XP, afterward it will work in Linux. What card is it?

Ok. I assume you are trying to connect via a wireless router or modem.
Your info shows an adhoc connection with encryption "off". I would try editing "network connections" in preferences, your specific connection. 1. Change 'adhoc' to 'infastructure'. 2. MTU should read "automatic". 3. IPv4 settings should read method "automatic(DHCP)". 4. IPv6 should be set to "ignore". 5. wireless security should be set to one of the wep settings. These you will have try one by one. Most likely wep 40/128. See if that does anything for you. |

What is the ip from the router? Are you using the same router for wireless and wired? Why do you have 192.x.x.x for wired, and 10.x.x.x for wireless? Please post the output from Code:

Hi
I think you might be right that I actually have not the appropriate driver installed. I have a BCM4313 card installed and the linux driver is broadcom sta but it does not specify BCM4313 cards. I found another more recent driver from broadcom here: http://www.broadcom.com/support/802.11/linux_sta.php. I would like to install this one and see whether it works. However, I am not really sure how to install it properly. I downloaded the file and extracted it but I don't even know exactly in which directory it went. Maybe somebody could give me more detailed instructions on how to install the driver. Thank you very much for your help. |
I use the same router for wire and wireless. I don't know why there are different numbers.

I hate to ask the obvious, but no one else has yet. Are you sure you're connected to the wireless network from YOUR router? Given that 1) The IP addressing scheme is different and 2) iwconfig indicates there's no encryption on the network you're connected to while you say you're using 128-bit WEP, it makes me wonder if maybe you're trying to connect to a neighbour's wireless network.
I'd recommend doing the following: -Check the settings in your router when you're wired in, make sure you know the SSID, Encryption type, and Password -Delete the wireless connection from your Network Manager -Scan for networks and connect to the wireless network with the same SSID you pulled from your router Hopefully this helps. |
