sorry, just not sure what version this is. mandriva has year.0 or year.1, opensuse uses 10.0 or 10.1, this version i got from pclinux was whatever was available in July of this year.

[muungwana]

Did you say got connected to your network using a wired connection? can you find out the ip address if this computer?

you can get this info from typing "ifconfig" on that computer.

If restarting the router doesnt fix it, then you may need to manually change its settings. You should be able to enter the router and change its settings and it should have a setting for giving computers ip addresses, this option may have "dhcp" word in its name.

[Jeremy.Bailey]

yeah, i have the computer connected to an Ethernet cable now

go to pcc and reconfigure the wireless network and then choose "manual configuration" instead of "automatic ip" at one of configuration stages then use this numbers "192.168.1.100" for an ip address and then finish up and see if you will be able to go online using this static ip address.

[Jeremy.Bailey]

dang. no change.

[muungwana]

i though using a static ip address would allow you to go online since you will be joining the network with your own address bypassing dhcp on the router(dhcp server is the part of the router that gives ip addresses, this is the part that isnt responding for some reason).

You may need to go into the configuration page of your router and poke around and see if there is a setting or two that need to be turned on or off. The problem is not on your computer and nothing can be done on that end.

Why did the net go down in the first place? maybe somebody was playing around with the router's settings and changed something

[Jeremy.Bailey]

we were all gone looking at some house. no one was messing with anything. door is closed, so no cat or dog could have done anything.
Im losing my ethernet connection. someone needs to get to bed and im occupying it. i can still use the droid, but copying and pasting would be a nightmare.
i guess from what you said, it's not a pc issue.
do you suppose the router is bad?

[muungwana]

well, wired part of it works, the wireless part doesnt and the fact that all three wireless computers can not go online wireless strongly suggests a problem with the wireless part of the router.

Wireless routers are known to be susceptible to interference, maybe a neighbor powered up a wireless device and the interference is kicking you out of your network or maybe its broken, i just dont see how a wireless part of a router can get broken all by itself.

Most routers have an administrative page you can access to change its settings, you can look up on yours and see if you can change a thing or two. You may start by trying to use a difference channel. Wireless routers operate in difference channels from channel one to twelve. Try another one and see if it will work.

[Jeremy.Bailey]

If this makes sense, I solved the problem. If not, then, I don't know what to say.

Something dawned on me, I use the PS3 gaming system to on occasion, connect to the internet. How? simple. wirelessly.
It connected with no hesitation whatsoever. I then copied off the IP address, etc etc...
I went to the control center again, and erased the old network configuartion, then added a new one, this time with the info off the PS3.
It said "failed" when trying to connected. But within a few seconds, it showed it connected wirelessly.
Strange, but I am now typing to you from the PC that couldn't connect to the internet for a good day.

i appreciate everything you have done. Been very helpful, and I have learned some things because of you. Thanks.

[muungwana]

did you have to do the same on all wireless computers?

can you run this command as root on the computer you use ps3 settings on?

cat /etc/sysconfig/network-scripts/ifcfg-wlan0

[Jeremy.Bailey]

I went under the network info on the PS3 and used that on the computer. I did remove the connection first, then added it.
it showed it failed, but after a few seconds, it connected to the internet. Did the same on the other PC.

[muungwana]

can talk a little bit about what network options u used from your ps3 and if there are any difference you noticed compared to network settings on your computers that used to work but stopped. This happened to you and it will most likely happen to somebody else one day and you will do the forum a great favor if you look into this and document what you will find.

[Jeremy.Bailey]

all I did was go to the network settings, and checked what IP address, SSID, etc that the PS3 was using. I redid the configuration in the control center, selected manual instead of automatic.
It connected even though it said it failed.
But now, as I boot up to the PC, it showed it was not connected

I guess it's not as solved as I thought it was.
