Ubuntu Networking :: Wireless Goes Out When Another Computer Turns On
Feb 9, 2011
I have an Asus Eee S101 netbook running UNE 10.10. When I have the netbook on, I have no problems connecting to my WPA encrypted wireless network being broadcast by a Buffalo router running DD-WRT. When I turn on my desktop computer in the other room (running Windows Vista) which also uses the same wireless network, the netbook disconnects. Then it will take a few minutes to reconnect. Periodically it will do this until the other computer is powered down. I don't know if this is an OS issue or the hardware, but is there any sort of troubleshooting I could do to look into this? It seems like the desktop is somehow interfering with the netbook's connection, booting it offline.

suspend has always worked fine with 11.04 and now it stopped working a few days ago. How can I figure out what is going on? The display turns off but the computer never turns off and the only way to bring it back is to hold the power button down and then start it back up.

I use ubuntu netbook for an eee pc 1000h because windows is underpowered. I got it working perfectly in 10.04. I upgraded to 10.10 thinking, if they got it right with 10.04 then surely 10.10 should be fine. All function keys except wireless work.
1. After sleep, wireless turns off. Have to restart and re-enable in bios.
2. If I disable and the re-enable wireless networking it tries to connect but never does resulting in a reboot needed. Checking bios wireless is enabled and connects perfectly on reboot.
Just don't close the lid and sleep because you need a restart. Why would 10.04 be easy and the new version fail? I am windows user and linux does not do this kind of thing normally. MS screws things up with upgrades not linux surely.

my computer this morning, then it suddenly turns off. I press the power button and nothing happens. After a minute I press it again and it turns on, but it quickly shuts down when it hit the boot screen. After I tried turning it on again, but it turns on for about 2 seconds and quickly dies. Some times it turns on itself and then turns back off. This happened when I had WIN XP installed too (which was about 2 years ago). I run full Ubuntu 9.1, no double boot. Is this hardware problem or a virus that affects both Windows and Linux? :O

I have an 9.04 installation of Ubuntu.After a classical system update via the GNome-GUI my computer (laptop ASUS PRO55series) got the sick habit to turn off abruptly during work.It's like if there were no electricity in my house.It is not the hardware since I also have windows vista and it works fine.I suppose this is from ubuntu; it could be from the heat regulation, that ubuntu thinks it is too hot inthere and just turns off the laptop.

I just installed Ubuntu 10.10 32 bit on my desktop and I've encountered a curious and somewhat frustrating issue. It appears that when I plug a flash drive, external hard drive or MP3 player into a USB port my computer turns off. Sometimes it happens instantly, other times it occurs a minute or two later when I'm transferring files. I'm not sure how to approach this issue. I've searched the forum and haven't found any mention of this. I am working on said desktop and all other hardware seems in good working order. If it helps, This is a 3 year old desktop with an AMD Athlon 64 X2 4600 cpu, a ABIT NF-M2S AM2 NVIDIA GeForce 6100 motherboard, an EVGA GeForce 7600GT video card and a SATA harddrive. I can post a log if someone wants, not sure which one to post though.

I have 2 computers, one running Ubuntu 9.10. I don't often use this one and rather than turning on the power point & having the computer automatically comen, as my Windows machine does, you had to press the power button to switch it on.As of yesterday - after not using it for some time - it turned itself on when I turned the main power point at the wall on to use my other computer. Thought maybe the button was knocked, but this has happened twice since. Seems it's mysteriously changed to automatic start up I can't work out how to change this. Can someone tell me what settings need to bechanged to have it not turn itself on until asked, please?

My laptop will be fine, then it turns off then immediately boots itself to a blank screen and no hard drive activity. This has happened 3 times today and never before. what ive done so far The first time this happened i tried turning it off and back on, still no screen and no hard drive activity so i took one of the RAM sticks out. Booted fine... To confirm that the RAM was bad i put it back and tried booting again, unfortunately it booted fine... i thought it was a fluke.
Until his happened a second time and instead of taking the RAM out, i waited a half hour and rebooted and it started booting fine, i turned my back for a sec and it was dead again. I have taken that RAM module out and am hoping it will not happen again, but it could well be the other RAM module since i really don't know or even if it is RAM at all.
Question is. Is this a RAM issue or something else? Where can i find a log to see what happened immediately prior to it offing itself? What's the chances it's the heatsync? (the laptop doesn't feel as hot as it sometimes does)

I had Ubuntu installed on my old laptop in dualboot with windows. This year i bought a new Sony Vaio VPCS12M9E preinstalled with windows 7 pro, but i liked the idea of having the opportunity of chosing between windows and ubuntu, so i downloaded ubuntu 10.10 and burned the ISO-image to a disc, and restarted my laptop just as i did when i installed it on my old laptop. The problem is that when i boot the disc after restarting the computer, the screen just turns black. What can i do to install Ubuntu?

I need straight forward directions on how to do this. I installed samba on ubuntu and I shared a number of ubuntu files. No luck.Xp can't see ubuntu and the reverse is also true. My searches just end up off on some tangents. Example, researching samba - I get the entire manual on samba - can't find the specifics I need within that document.

Was wondering if anyone had a idea on how to install this wireless adapter onto a computer thats running Ubuntu. I don't have access to a direct connection so that won't work. So I need a way that I could install it without internet, I do have access to another computer that i could get files off of if needed.

I am using an HP dv6 series laptop. The wireless works fine in Ubuntu 9.10 (must install the Broadcom STA wireless driver). When I try to use Kubuntu 9.10 my computer crashes when I try to install the driver. Is there any particular reason why it works in one and not the other?

I have a Belkin Wireless G F5D7230-4. I was attempting to configure a wireless card on another computer on my network when it froze during the reboot phase after making settings adjustments. The wired connection is fine, except on that computer that I was making the adjustments from. It won't connect at all. I plugged a friends netbook into the same wired line and it connected. Also there is no wireless signal on any laptops. Mac, Win Linux, don't matter. I tried all the various methods of resetting to default but still when I try to access the router's config page @ http://192.168.2.1 I get the error Code: The server at 192.168.2.1 is taking too long to respond.

I'm trying to make my wireless router always give me the same ip address every boot (192.168.1.100). I do not have a static ip address from my isp.
Everything I've tried from online help has made my internet break and I'm not even sure what exactly I should be searching for on google.
Ultimately, I'm trying to get my wireless router to forward ftp requests to my computer which shares the network with an xp machine. I think this is the way to go about it.

The first two times I entered the wireless key on the prompt that appeared shortly after login, the computer froze completely. ctr-alt-f1 ctr-alt-backspace did nothing. The third time, I closed the first prompt and after 10 minutes I tried connecting again. It didn't freeze, at first. The internet worked. It took about 10 minutes later for it to freeze. Now, whenever I boot up, it freezes a few seconds after login. I can boot recovery mode, but I don't know what to do from there. Heres some info I got from the recovery mode:
Computer Brand: Sony PCV RX850
Ubuntu 10.4 32 bit 2.6.32-21-generic i686
Realtec 8185L chipset
iwconfig

Since I upgraded to Lucid, I am dealing with serious instabilities related to my wireless card. What happens is that when there is a lot of wireless activity the computer freezes. It is a complete freeze, the mouse stops moving, if something was coming out of the speakers it keeps echoing, and the only solution is to turn off the computer. The bug seems to coincide with the one listed in here

My wireless card is Intersil ISL3890/ISL3886. My whole computer is an HP z555. I'm thinking that is should be a bug in the wireless adapter driver, which is p54pci. The only solution I can think of is to blacklist it and set up ndiswrapper. I am not very comfortable with this solution since a native linux driver should be better than ndiswrapper.

I am in a situation at the moment which means I am going to be without an ISp for a week or two, and I can't survive that long without the intenet!!! What's more, I have 8 computers that need to connect, though not necessarily at the same time, but certainly more than one at a time. Anyway, I came up with an idea to buy a Mobile Broadband Dongle, and then share the connection via my PC. Problem is, I don't know how I would go about setting my PC to be a Wireless Access Point/makeshift Wireless Router, and sharing the connection.

I am trying to connect to an apple computer wirelessly to get access to the internet.. If no encryption is used on the network (gateway?) set up by the apple computer I can connect just fine and browse the internet.
-If a WEP encryption is introduced I cannot seem to connect... even though the WEP keys are identical.
-I have tried both WEP 128 passphrase and WEP 40/128 key... -Have tried the WEP passphrase being both just numbers in case that mattered.

I want to make my computer invisible or hidden to the other computers connected to the same wireless network. In other words, I want to turn off network visibility or network mapping. I think this amounts to the ability to turn on and off the Windows Link-Layer Topology Discovery (LLTD) Responder. [URL]... On windows, I believe this would be comparable to setting the wireless network as Public instead of Home. I like to share files using Ubuntu when I am connected to my Home router, but I don't want to be discoverable or visible to clients on a public wifi network.
I have already created a shared folder on my desktop which installed some sort of networking components to interact with Windows, but I don't want the public wifi network to see this folder, or my computer name at all. I want to be invisible to other clients on the same network. Right now I am visible and can see other clients connected to this public wifi router.
(In case some ask: I do not want to disable SSID broadcasting on the router as it is a public wifi router that I do not have access to.) Can anyone explain how to do this (preferably with a GUI method so I can reverse the steps when I connect to my Home network)?

Hey I just installed linux on my computer and it will not connect to any wireless networks, it will detect them and say try to connect but for some reason wont. It does connect just fine to a wired network.

Installed Ubuntu 10.04 on my Sony UX280p with Intel 4965 wireless. Ubuntu detects the card without issues (as far as I can tell). I can see all access points in my area and select my access point and pair with it. I get a DHCP address from the AP (if ifconfig is to be believed) and iwconfig shows the ESSID of my AP but I can't ping the AP or any other computer on the network, nor can I ping the sony from any other computer on my network. Last year I had installed 9.04 on this computer and wifi worked out of the box without any issues.

just switched from Windows Vista to Ubuntu 10.10 on my Toshiba laptop and I'm loving it, except for some wireless connection problems. About 70% of the time, my computer is unable to find any wireless signals whatsoever, despite being right next to the router. When it does find the signal it connects fine and runs great, but most of the time it doesn't show any signals at all. I can't find any pattern to when it does or doesn't find the signal. My result for the "sudo lshw -C network"

I first noticed the problem because my wireless internet will stop working. The usb stick has its LED constantly on but it fails to connect. I have tried some methods of restarting the networking, like "sudo restart network-manager", disabling and re-enabling the wireless and networking from the taskbar applet. I tried removing the module and restarting it. It might be a bigger problem because I'll find that things will randomly hand for awhile, like opening system monitor, or running terminal commands. They do eventually run but only after several minutes. A restart seems to get everything working again, but the problem comes back at random times. I am willing to solve this right now as I have time, just let me know what info you need and I will post it.
Update: Some more info I forgot to include. I am running Ubuntu 11.04. It just froze again, I tried logging in and out but the internet still wouldn't work and things were hanging, I couldn't get file manager open. I have even tried shutting down the computer and had it stall on the Ubuntu logo with the dots loading so I had to hard restart.....

I am wanting a computer with an external dialup modem (ppp0 modem through a com port /dev/ttys1) to act as a gateway to the internet, forwarding internet traffic through ethernet (eth0 is set to static 192.168.2.2) to a router (the router is 192.168.2.1) where it will be broadcast to other wireless computers like my laptop (192.168.2.3). I've had this setup until recently when the gateway computer (the one with the modem) died. Now I'm replacing that machine with another box and an install of Ubuntu 10.10 but so far things aren't working for me.
Success so far:I have dialup access working on the new box. Took me a while to work out the configuration for getting dialup working, though the IP address is Dynamic (or it won't stay connected), "Check carrier line" is off, and "Ignore Terminal Strings (stupid mode)" is on in order to successfully connect and stay connected to my ISP. I also had to make my normal (non-root) user "lancer" a member of the "pid" group (the reboot) in order to use gnome-ppp as non-root. The laptop (192.168.2.3) is successfully connecting to the router (192.168.2.1) as I can see the router configuration page when I type http://192.168.2.1 into the laptop's web browser. This setup is unchanged from how I had it before when this was previously working and I don't want to change how the router itself is set up. What I want is to know what to fix in the new box in order to get it connected to the router (through ethernet) and bridging the internet through.
My problem is that whenever I plug in the eth0 from the gateway (192.168.2.2) to the router (192.168.2.1), Ubuntu's automatic plug-me-in network detection kicks in and I find my dialup no longer working through some kind of IP conflict (at least that's what I think it is). Maybe I don't have the "gateway" correctly assigned? (in the gateway computer for the ethernet connection, I had it pointing to itself as I don't know what to put for "gateway IP" as that is automatic So, just to check my connection, here I am pinging google (from the gateway computer which has the dialup modem) once a dialup connection has been made.
Code:
lancer@lancer-desktop:~$ ping www.google.com
PING www.l.google.com (74.125.237.17) 56(84) bytes of data.
64 bytes from 74.125.237.17: icmp_req=1 ttl=55 time=179 ms
64 bytes from 74.125.237.17: icmp_req=2 ttl=55 time=176 ms
64 bytes from 74.125.237.17: icmp_req=3 ttl=55 time=158 ms
[Code]...
What do I need to do in order to make Ubuntu of my gateway computer stay connected to my dialup but also simultaneously share an ethernet LAN to my wireless router and feed traffic to the other computers from there? I have googled this but some of the most promising instruction (e.g. http://www.ubuntugeek.com/sharing-in...in-ubuntu.html) call for packages like dnsmasq or ipmasq which seem defunct now in Ubuntu 10.10. Other pages seem to suggest dual-networks "can't be done" in Ubuntu [URL].. (what!?! I had it before my other gateway died)

I'm not sure where to post this but seeing as how, at least as far as I can tell, the problem is related to the wireless card or drivers, I figure this is as good a place as any. On to the problem, I recently install openSUSE 11.2 Gnome on my MSI Wind U100 netbook. Everything appeared to work fine right after install, wireless and everything. However, soon after that I began having issues where the screen would freeze and I would be unable to do anything until I force restarted the computer.
Now I believe the problem is related to my wireless as this problem occurs most frequently when I am either downloading a lot of data over wifi or fiddling with the network. I have had it freeze many times while switching wireless networks or while experiencing wireless issues such as an intermittent connection. I may be completely wrong in my above analysis of the problem, but I figured i need to post somewhere to get started. If anyone feels this post may get more help in another forum, please just let me know.

I set up a dhcp server in the lan and assigned static ips to two computers, computer A and B, according to their mac address. Everything was running fine. But when I turned off computer A, connected computer C to the network, and assigned computer A's static ip to computer C without changing dhcp setting. Computer C was able to access the internet. When I turned on computer A, dhcp couldn't assign an ip address to it, and computer C showed an error message of ip conflict and failed to use internet. I wonder if dhcp server is able to prevent other computer from using the same static ip that is already assigned to a computer according to its mac address.

My wifes networked computer connected to the network just fine when it was Win XP. Now that Ive converted it to 10.04 (completely) it can see the network, but it just wont connect to it. I had no problem converting my computer to Ubuntu and it sees the network and accesses it great. Files, folders and hard drives are all shared. So, one computer connects great, the other does not.**I dont know what to do at this point.Here is the layout:My Comp (10.04) ---------......Main Network Comp (XP)Wife Comp (10.04) -------/The main network computer is XP as it has software on it we need that does not work in Wine. The main computer will have to stay XP. I cannot get my wifes computer to connect to the main system, although mine connects just fine. I dont know what the problem is. Her computer sees the network, but when trying to connect, it times out and says unable to connect.
