I have one major problem that is going to cause me to switch back to windows. My wireless network shows connected and works fine for a while but periodically stops working. It always says it is connected but sometimes stops working to where I have to disconnect and reconnect for it to start back up again.
View 9 RepliesNew Toshiba laptop dual booting with Windows 7. I really like MM 10.10 and most things are working great! Periodically I will be web browsing and I lose connection. At first I thought it was Firefox but if I try to disconnect wireless and reconnect it will no longer connect unless I reboot. My network is hidden but Ubuntu finds it no problem on a fresh boot and connects per my settings and it is not a network problem since I can connect to Windows all day long and the rest of the family never has problems.
My wirless device is: Realtek Semiconductor Co., Ltd. RTL8191SEvB Wireless LAN Controller (rev 10)n and all OS updates are applied that I can find. I am thinking about un-hidding my network since years ago that used to be a problem with Redhat and even early Ubuntu but beyond that I cannot think of what else to try.
I have a wireless network using this driver:
Bus 001 Device 002: ID 0bda:8187 Realtek Semiconductor Corp. RTL8187 Wireless Adapter
and everything works fine for some time. After a few hours or maybe less (if I push bandwidth to the limit) the Internet freezes. I can't even ping my router. If I disconnect and reconnect either the device or the connection via network manager , it does work for a minute only and then freezes again. If I restart Ubuntu entirely, it works again. But for a while...
It works 100% in Win7 and I have no problem at all there. But I am very annoyed that I cant have reliability in Ubuntu. I want Ubuntu as default.
It has something to do with drivers or an inner variable or buffer or something.
At least, is there any way to reset my network connection without rebooting the OS?
I tried sudo /etc/init.d/networking restart but it gives me: Ignoring unknown interface wlan0=wlan0.
I'm new to Ubuntu and i set up my wireless myself and I think I may have put in wrong settings. I looked through the forum and found these commands to put in the terminal from other posts. Could someone please see if they can fathom what I've done wrong. I have an wG111v2 netgear usb which works fine in windows but is very sluggish on Ubuntu. It worked for a while but since i have deleted and reinstalled my wireless numerous times I now can't get iternet at all. I have Ubuntu 9.10 on my machine which I duel boot with winXP.

I tried the dig command and got the following message:global options +cmd; connection timed out; servers could not be reached;
my netbook (running 10.10) has recently decided to only work with my wireless for a short while after connecting. After this time, it just won't load a page at all, but remains connected to the router. Disconnecting then reconnecting to the network allows me to use the internet again, but only for a short while. This is a recent problem, and the netbook used to "just work" with wireless.

I'm having some problems with wireless, it works fine on boot but after a while pretty much randomly, it can be a few days or it can be a few hours, it stops working. I'm not sure which command would tell you what and it would take a little while to debug it because like I said it's random, but if anyone knows what to do please tell me! I'm on Lucid Lynx 10.04.Another something that's really bothering me (But not related to wireless) is that for some reason when I restart my computer, the top panel keeps changing the applets locations.

I have a Sabrent USB 802.11N adapter. (I am using 64-bit Ubuntu in all below)
I plug it into a 9.04 box and it works fine. Plug it into a 9.10 box. Network manager sees it and can attach to the network, but has 0% signal strength, no internet.
Rebuild the 9.04 box with a fresh install to 9.10. 0% signal, no internet. Try 10.04 Alpha 2, 0% signal strength, no internet.
Rebuild same box down to 9.04. Works perfectly. 100% signal strength. I do all updates and then the upgrade to 9.10 using the USB. Everything works fine until the reboot. Then, USB connects, but 0% signal strength, no internet. Oh! ifconfig says the wlan0 interface is up, but it has a random ip address.
I don't mind using 9.04 because for the forseeable future, the box is just going to count aliens for Seti, but my wife wants it off the counter and I would like to upgrade someday.
My Ubuntu when i start it up, go to the wireless networks , try to connect to my network it trys to connect stops than says disconnected. My internet card is a Cisco Aironet wireless (idk the model number)
View 1 Replies View RelatedI'm running Squeeze and I'm looking 3 days now for a solution in some weird problem. The NetworkManager Applet shows that there isn't connection although I am connected. The icon has this small "x" and when mouseover it says "No network conncection". Moreover when left clicking it, it says
"Wired Network Device not managed"
While I was looking for the solution a came across this post by an Ubuntu developer who says:network-manager-applet displays the connectivity state of network-manager's managed interfaces not every interface. So the title "network manager says disconnected but is connected and working" is actually misleading. The interface is connected and working but not from network-manager's point of view since it is not managing the interface. Additionally, in Lucid now network-manager applet displays nothing now for non-managed interfaces so is less misleading. You can check to see whether or not an interface is managed by network-manager by using the command line too nm-tool. You'll see "State: unmanaged" for unmanaged interfaces.
I have a problem with my wireless connection in ubuntu (natty with amd64bit) There seems to be intermittent disruption in my connection. Havent seen a pattern as yet, though it happens once a day. After that I cant get it to work at all and only restarting + reconnecting the USB device helps. Dont know what is going on.I have already read these pages : Commands and Wireless Troubleshooting.Here is my line of though1) Given that I am able to connect other devices to it while I am not able to connect through this desktop, I think the router is OK.2) I am able to work with it after restart + re-connection . And so the driver is OK and is loaded. The driver seems to be oK and loaded even while I am not able to connect.So why is this happening and how can I get this under control without having to reboot and re-connect the device everytime.Here are the output for the commands which will give you a more detailed idea of the process. Before reboot while I was not able to connect:

I've installed Ubuntu 10.04 32 bit version(dual OS) on my 64 bit Pentium core2 duo 2.2GHz processor. Everything seems to be working fine except it's not getting connected to wireless network, although it's detected the network .It was working fine(got connected to wireless network) when I had installed the same OS via virtual machine.
View 9 Replies View RelatedI upgraded to 10.10 the day it came out, and haven't had any problems with internet stuff. My wireless card works without any proprietary drivers. Last night, the computer stopped connecting to the internet. I am still connected to my wifi network, but I can't do anything online. I had assumed that my internet connection was just down in general, and tried resetting the computer, shutting down the computer and then turning it on again, and rebooting the modem, but then my Xbox connected, and my laptop running 10.04 connected, so I'm confused as to what is going in. Any ideas?
View 2 Replies View RelatedMy Acer's Wireless randomly stops working until you fully shut down and start the computer.(Not Restart but Shutdown->Powebutton) I am using Ubuntu 10.04 Lucid.
I am wondering if anyone knows why it would stop working properly, and/or how to fix it?
And since this is a off and on problem I might not be able to provide details immediately from time of crash, since I need my computer on the wireless.
One symptom that really stands out is that the cooling fan is spinning as fast as it possibly can and processor usage is spiking around 80/200 on a process called phy0.(relevancy unknown)
As I was typing this post on my other computer, my laptop crashed and I lost the lshw -C Network output I had. If asked to, I will post the one from when it is working. Also I will post any other info you need from when I can.
I'm running a Source Dedicated Server on my Ubuntu laptop, and to connect to it via external IP from other computers in the network I need to enable loopback in my router.This was working fine, but then I disconnected my laptop for a few days, and when I came back the wireless stopped working on my Xbox. I reset the router to factory defaults, and then setup everything again. It was all working fine until I enabled loopback again and power cycled my router. Now every time I do that, the internet on Ubuntu stops working and the wireless on the Xbox stops working.
Edit: You can ignore this I guess. It seems I was actually DISABLING loopback by enabling that router option, which I guess caused this. Strange, because the first time enabling this option was the only way to get my external ip to work. Oh well, everything is fine now.
I have a WET54g bridge that I am trying to get connected to a wireless network that only allows DHCP. The idea behind it is that I would like to connect the Cat6 out of the bridge to a switch allowing multiple wired computers to connect to the wireless network. The bridge will easily connect to the network once I put the WEP key in, however, there is a kink after that. When I connect the Cat6 to my computer and request an IP for that computer, it self assigns. This tells me that it is not talking to the wireless network through the bridge.
I can not find which IP address the bridge was assigned so that I can talk to it. The sub net is 255.255.240.0 which leaves quite a few possibilities. I know that the bridge is, however talking to the wireless network because the light is steady on the front of it which indicates just that. One other thing to stack on is that I know that there is a "splash page" which comes up when any computer connects. You click on the agreement and then you are allowed onto the network. How can I get my computer to talk through the bridge to the wireless network?
I just upgraded to 10.04 from 9.10 and I ran into few issues.
Laptop - Dell Vostro 1520
OS - Ubuntu 10.04 64 bit
Issue - My wifi connects to the network properly and shows connection established. But I am not able to browse. I tried ping and I didn't got any response. But I was able to get response when I use ethernet (wired connection) and I am able to browse. No issues with wifi card as my wifi is working properly from Windows and with the same network. I did a complete update again before posting this and it is yet to be resolved. Here are the output of some commonly asked outputs with wifi enabled and connected:

I've installed ubuntu 10.04 on a hp mini 110. I've used netbook remix on this same computer and had no problems with a wireless connection. In this case, network manager shows wireless disabled. I have installed the Broadcom B43 Wireless drive from Adminstration->Hardware drivers. No help! ifconfig does not
show eth1 and lspci tells me that the Broadcom BCM4312 Network controller is present.
I'm running Ubuntu 10.10 Maverick Meerkat 64-bit on my desktop with a wired internet connection (with no firewall). For the past 2 days, I have observed that1. Firefox randomly throws up errors like "Problem loading page" whenever I click on a hyperlink. When I click on Reload, the page loads up just fine. This has been happening a lot recently..and I do not remember updating anything consciously. By the way, ipv6 is disabled in Firefox.2. The network stops working all of a sudden (usually indicated by the Firefox error). The Autho Eth0 indication is active, but I am unable to connect to any external machine.
3. Needless to say, this error is manifesting itself in apt-get as well. I get "something wicked happened" errors all the time, and am unable to download or install anything.That this is not a problem with the ISP is obvious because I also have Windows (from which I'm typing this, ironically), which is able to access the internet.Is this a bug in Ubuntu 10.10?
I upgraded from 9.10 to 10.04 and my wireless card no longer works.
The card is a Dell 1450 USB a/b/g card.
lsusb sees the card. device id is 413c:8104
dmesg says that p54usb is trying to load firmware isl3887usb but that failed (error -2)
I looked in /lib/firmware and didn't find that file
ps. god why did i upgrade?
I have a Dell E6500 with and Intel 5300 wireless agn card running Lucid x64. Wireless works fine and speeds are great except when I download with either the browser or thru a torrent or even updates. Once I get to around 100 megs in to the file wireless stops working and the only way to get it working again is to disconnect and reconnect to the AP. I have installed the back ports and tried several other fixed to get this to work but nothing has helped. One more note this happens on 2 other wireless routers that I have tried so I know that it's not limited to my Linksys.
