Internet connection went down, others can connect again but not me

[Jeremy.Bailey]

Last night, my internet connection went down. This morning, I came back on the PC to discover that it's still down. I was told that my sisters internet was down, but is up, and someone else can use it too. We're using the same router, all are wireless. I don't know why mine doesn't work. Any ideas?

Well, you are not giving any details away, so have look and see if any of the items here does anything

[Jeremy.Bailey]

Any detail you want, ill be glad to  give but I don't know any konsole codes to check the configuration or any tests. I'll check that link

[Jeremy.Bailey]

I am not on a computer, but rather a droid phone. So I can't copy/paste but will do my best. When typing iwconfig, in a nutshell I get:

no wireless extentions.
it shows the SSID, but tx power is off, fragment thr is off, rts thr is off, power management is off.

[wedgetail]

Well I am better in the command line stuff but.

1.. Restart your pc I will assume you have done that
2.. Power to wireless is turned on? Switch on pc?
3.. Go into PCC Network and restart the network

[Jeremy.Bailey]

1. Complete
2. There is no switch. A button. Appears to be on.
3. Went into the PCC, resetted settings, no change.

I apologize for not being able to copy/paste commands, but with no internet, it's hard to do.

Are there basic enough ones? I'll check to see if I have some spare ethernet card.

Try opening a console window and as the root user type in the following

service network restart

See if that helps out.

you have said your internet isnt working but you havent said where exactly it is broken

how did you used to connect? i assume you clicked on the network tray icon to get a list of access points and then you select yours and join the network. Can you still see the above? can you see your router on the wireless network list and can you select it? does it error out here and refuse to connect you or you can join the network but you just cant go online

try this:
1, power down your computer
2, turn off and then on your router and then wait for around two minutes
3. restart your computer and then wait for around two minutes and then try to connect to your router.

[Jeremy.Bailey]

tried the three steps, no change.
as for the other command:

[root@localhost jeremy]# service network restart

I am now in someone else's room with an ethernet cable connected to the router. not sure how long i will be there for the night, but if anyone wants command lines copied and pasted on here, please ask for it now. thank you.

[muungwana]

what does this command give you? run it as root

cat /var/log/syslog  | grep -i wlan | tail -n 20

ps:
copy and paste the command to make sure you dont mistype it

copied and pasted:

The above lines show your computer is asking the network for an IP address but your network is not responding for some reason. The problem is on your network and i think you will have to do something to your router to solve it, maybe turn it off and on.

This does not explain why other computers on your network work fine, what operating system are they running? do they use a static IP or a dynamic one? They should all have the same problem if they all use IP addresses requested from the router.

[Jeremy.Bailey]

My sisters doesn't work anymore now either. i was on mandriva 2010.1, and now pclinuxos, newest one, neither work. both sister and mother are on mandriva 2009.1
not sure if its dynamic or static. any way to check? most likely, whatever is default.

[muungwana]

The default is to get an address from the router and the fact that all now do not work strongly suggests they all use dynamic addresses requested from the router.

Can you turn off the router and then turn it on? Maybe it is confused and all it need is to be restarted. We dont know what kind of a router you have and we cant help you on how to fix it

[wedgetail]

If muungwana's suggestion of the restart does not solve it

This error

RTNETLINK answers: Unknown error 132

could be related to a soft block, though i don't understand how it could come about in a running system. It is a simple check though

Install from synaptic rfkill and then in konsole run

Code: [Select]

rfkill list
post the result

What do you mean by the newest one: pclos 2010.10 the very very new one?
