Can someone please help me? I can no longer access the internet in Ubuntu 9.04. It worked fine previously in Ubuntu 9.04. I am connecting wirelessly with a PCMCIA card. I can connect to my network but when I open firefox I get "server not found." I have tried more than one card but still have had no luck. I am duel booting with Windows XP and the card works fine in windows. If I run sudo lshw -C network in the Ubuntu terminal it tells me that me card is disabled. Any help would be greatly appreciated. Also

You must have got this working originally, so eiither, unplug and reseat the pcmcia card then do the same install procedure again.

Are you suspending your notebook?
It may be possible that the card is not resuming from suspend properly.

Re: Ubuntu internet stopped working.

My wireless networking is already enabled. However, my internet does not work whenever I boot up my PC. I have tried taking my pcmcia card out and putting it back in but still have had no luck.
Also, when I resume from suspend it keeps on asking for my wifi password which I know I am entering in right but ubuntu refuses to connect to it. So I have to take out my card then put it back in for ubuntu to connect to my wifi. I did not have to do this earlier in ubuntu 9.04.

Re: Ubuntu internet stopped working.

Sounds like it might be a bug or some update has affected it. Dis you installa ny updates before this happened ?

 

[dabestharpis]

Re: Ubuntu internet stopped working.

I do not remember installing any updates.

Re: Ubuntu internet stopped working.

However, the last program I installed before my wifi stopped working were:

Installed the following packages:
firestarter (1.0.3-7ubuntu5)
menu (2.1.41ubuntu1)

After I a installed those programs my wifi stopped working. So I removed them, but my wifi still did not work

Re: Ubuntu internet stopped working.

What make and model is your wireless router?
Does it still work under windows.

At a terminal type iwconfig

Make sure the wifi card has got a DHCP address from the router.
You can also try ifconfig and the output of:
route -n

The last command you should see a default gateway, this will be the IP address of your router usually 192.168.x.x or 10.0.x.x in home networks.

Can you ping the gateway?

Re: Ubuntu internet stopped working.

I have a netgear router and the serial # is: 1J138B7U0D7CC. It still works under windows.

Re: Ubuntu internet stopped working.

Looking through your results,
Your wifi has been assigned ath0 , 10.0.0.2

Your router is 10.0.0.1 but something is stopping the ping from reaching the router, this is why you cant get online.

Try ping 10.0.0.2 (your own card) ctrl +C to break out the ping.

If you have updated your dependencies, you may have an old version of firestarter still on your system. You need to check through synaptic again and search for any other firewalls, as your system was ok before firestarter was installed. For quicker replied try ubuntuforums

If I search synaptic for firestarter it says it is not installed. If I search firewalls in synaptic the only programs that are installed are:
iptables
ufw
wget
The installed version matches the lastest version for those installed programs. Also, I already am receiving help at UbuntuForums, click here:

Re: Ubuntu internet stopped working.

I am not familiar with firestarter but had it been Microsoft I would be looking at the security level .. low to medium would always allow me to have internet access whilst high would stop everything. See if firestarter requires to be set up and addresses in the 10.0.0.x range added as friendly ..

 

[dabestharpis]

Re: Ubuntu internet stopped working.

I do not have firestarter installed on my PC. So how can I install it without internet?

Re: Ubuntu internet stopped working.

To quote your very own words

However, the last program I installed before my wifi stopped working were:

Installed the following packages:
firestarter (1.0.3-7ubuntu5)
menu (2.1.41ubuntu1)

After I a installed those programs my wifi stopped working. So I removed them, but my wifi still did not work

once you instigated settings with firestarter , removing or disabling the program will leave your PC with the settings enabled at the time of removal. You'd probably need to re-install, check the configurations and then bring it down to a setting that allows you to access internet before removing again.

 

[dabestharpis]

Re: Ubuntu internet stopped working.

Ok. So I need to reinstall firestarter to check its settings right? So how do I reinstall firestarter with no internet?

 

[Done_Fishin]

Re: Ubuntu internet stopped working.

didn't you save it to your disk somewhere ? Downloads ?? Desktop??

 

[dabestharpis]

Re: Ubuntu internet stopped working.

I installed via Ubuntu's Add/Remove Software. So I don't have it installed anywhere.

 

[Done_Fishin]

Re: Ubuntu internet stopped working.

it will have downloaded somewhere to your hard disk .. do a search and see if you have enough downloaded remnants to make an install

you might also want to try the same method again .. it may have a cache for downloaded repositories

 

[dabestharpis]

Re: Ubuntu internet stopped working.

I tried downloading it again (from the Add/Remove software and Synaptic) but they both told me I need an internet connection. I did a search of my filesystem for Firestarter but only 3 files were found:

firestarter.desktop in: /usr/share/apt-install/desktop
type: desktop configuration file

firestarter.png in: /user/share/apt-install/icons
type: PNG image

firestarter_1.0.3-7ubuntu5_i386.deb in: /var/cache/apt/archives
type: software package

It tried installing the software package but Ubuntu told me I needed an internet connection to install it.
