I have updated my system to 9.10 it is show my connection but when I go into firefox its shows it can't get online. What do I need to do?:(

What do you see if you execute ifconfig in a terminal?

Does firefox have a proxy set ( Edit -> Preferences, Click advanced, then the network tab, then the settings button. Unless your ISP are a bunch of jokers, you want 'No Proxy' ticked. )

January 5th, 2010, 07:10 PM

Please post the output of

lspci | grep Network
(the | character may be found using Shift+\).
It may be that you need to install a firmware driver or that the wireless signal is poor, hence the large number of errors.

Edit : I'll wait

I am confussed do I type that into the terminal?

January 5th, 2010, 09:00 PM
I tryed tried the code and it said it could not be found

Ok..picking up where I left off...

Up on the grey bar on the top of the screen, between the speaker icon and the envelope icon on my system, is the network icon. Right click that and go to Edit Connections. Then click on Wireless, you should see your router's name ( I'm assuming you're using a router, tell me if I'm wrong, it should be the same name as your windows computer I assume your typing these posts on :) ), click on it to highlight it. Then click edit, then always allow on the pop up. Next, click on the wireless security tab, delete the Key field and retype it (this should be your wireless password. Make sure you get it right, we used to get loads of calls about this when I used to do this for my job :P ).

Apply and close, see if that fixes it.

Done that several times no good also is is showing my router just nothing connects. Oh the computer I am typing on is not my Linux machine its down in the basement and take me a while have bad arthritis so it take me some time to go back and forth.

Sorry to have you moving back and forth so much. Human error was a huge issue with wireless keys when I was a phone monkey.

Okay... if you could try :

dhclient wlan0

lshw -c network

and type up the results of each, we should be getting fairly close to a solution.

Whoops. My fault, chatting to my housemate about her mum. Try

sudo dhclient wlan0

well I must stop for today thank both of you for your heip.

The commands in post #6 are for terminal. The lshw command should be

lshw -C network
as linux commands are case sensitive.
Please post the make and model of your wireless adapter. Can you connect the PC to the internet via a LAN cable ? If so, then connect it and then go to System-Administration-Hardware Drivers. This will look for third party/manufacturer's drivers for your hardware (wireless and display adapters usually) and install them.
