Ubuntu :: Slow Start Up And Loss Of Wireless?
Jul 6, 2011
I switched to Ubuntu from Windows a few months ago and have had it all working fine since.
I turned on my system today and did some updates, then restarted but after the boot selection screen which I cant use as I have a USB keyboard the screen went to that purple/pink colour and froze for ages. Eventually my desktop appeared so I tried restarting it again and the same thing happened. Before from the boot selection to my desktop would only take 5 seconds or so but now it takes about 3 minutes.
Also since the updates I can't connect to my wireless network. I was using the Windows Wireless Networks software from the Ubuntu Software Centre, now when I try opening it manually it just hangs. I tried removing it and reinstalling it but still no joy.
I may have been too trusting with the updates so didn't read the list, I just updated and restarted and thats when the problems started.
I'm not quite sure what information you need but here are the bits from the System Monitor:
Release 11.04(natty)
Kernel Linux 2.6.38-8-generic
GNOME 2.32.1
On windows I would have considered myself an intermediate user but since switching to Ubuntu I feel like a beginner again although im learning fast.

No improvement since I first reported this problem, I am hoping somebody can now advise.
Using openSUSE11.3 Linux 2.6.34.7-0.5-default i686 with kde 4.4.4 release 3.Problem is the wait of sometimes over 2 minutes before the wifi connection is available.Two questions:-
1. Why does it take so long? Longer by far than it to be with previous openSUSE releases. Much longer than with that other OS!!!2. How do I remove the wallet process. Not needed in present environment so I would like direct connection without having to open wallet. I didn't set this up, it just happened after I had upgraded to 11.3 and I need to know how to disable it to save time.

I have a home network consisting of 1 Linux box running Fedora 13, a laptop running Windows XP, and an HP Officejet Pro L7780. With the Fedora 13 box I have Firefox 3.6.4. I have noticed in the last couple of days a very sluggish response seemingly one site, amazon.com. I'll connect to the site but Firefox remains loading the page and parts of it will be missing. If I search for a particular item it takes forever to display parts of the newly requested page. I have hit stop and then refresh and sometimes the page will then come up although it's never 100%. Eventually I'll loose my router (which by the way is a Linksys BEFSR8.1 v3.01), in that if I ping it I'll get the error that it is unreachable. The laptop also looses access to the router. I'll then reset it (unplug/plug) and it'll come back up ok until I go back to Amazon and start searching again.
My question(s) are:
Can a router go bad and just show up bad with one site initially? In other words is the router slowly dying?Can a problem with a site affect the router this way?I have also changed my namserver settings in /etc/resolv.config and on the router with no real change in symptoms. It's always Amazon and I don't seem to have issues with any other sites that I visit. Any clues?

I have problems with my network speed when i ping my proxy server I end up getting a high packet loss generally more than 30%.I have tried to use various network monitoring softwares like etherape, wireshark, tcpdump but I am not able to get to the bottom of the problem.basically I am trying to find out where the lost packets are going.

I have a new Toshiba Satellite L450, and decided to run Ubuntu, which is new to me. I am running a 64 bit Karmic, and there is no driver that works. So, to make a long story short: a friend helped me get a driver on my Desktop, namely: rtl8192se_linux_2.6.0100.1012.2009_64bit.tar.gz We had it working, but when I let in the first large batch up updates, it kicked the driver out. I found instructions, installed it again. I let in the next updates, and it kicked out again, and this time the instructions don't work. So, I have two sets of questions:
1. Will updates always undo my wireless? Are there certain updates I should avoid if I want the wireless to stay up and running? (I just assumed the thing to do is just get the updates -- though I am guilty of having no idea what they were about.)
2. Did the updates cause one of my instrucitons to no longer work, or need to be modified?
They were as follows:
sudo apt-get install build-essential
cd ~/Desktop
sudo tar -xvzf rtl8192se_linux_2.6.0100.1012.2009_64bit.tar.gz
That 'sudo tar -xvzf...' operation is the one that stops me. Is there something to change in that line? It goes on:
cd rtl8192se_linux_2.6.0100.1012.2009_64bit
[Code]...
this worked the first time I tried it. I posted this earlier under 'hardware', and do not know how to get that post off, so I typed it here once I realized.

I have a hp dv3 laptop which dual boots Win7 and Ubuntu 9.1 64 bit. I have no issues with my wireless adapter in Win7, but I lose connection after a couple of hours in Ubuntu. When connection is lost it is not possible to view any wireless signals, the adapter is basically turned off. The only way to restore the connection is to reboot, then Ubuntu will again automatically connect to my WP2 encrypted router. My wireless adapter is a AR928X made by Atheros.

For most of today I had my internet connection dropping out on me intermittently. I assumed it was a provider issue, as it has been unreliable in the past. After it dropped out for good, and I could not print through network, I realised it was not a provider issue. All the other computers in the house were connected, including another ubuntu box. Only the MacBook Pro 5,5 was not able to connect. The network manager indicated I was connected to the network, throughout the whole time.
A number of restarts with the kernel I normally use (2.6.31-19) including one in recovery mode, yielded no change, but a restart with the 2.6.31-20 kernel resulted in connectivity. Finally, perhaps by chance, wireless started to work again on the 2.6.31-19 kernel, after I once booted into the Mac OS, and then back into Karmic. How I might go about diagnosing, obviously in hindsight, what happened? I suppose I should look in the log files, but I have no idea where exactly, and what to look for.

I have ubuntu lucid running on Dell 230 PC, linksys WPN600 N wireless PCI network card connecting to a Cisco E3000 dual channel router.
Kernel: 2.6.32-33-generic
Installed Ralink driver v2.4.0.0
iwconfig shows that the bit rate is 130Mb/s and link quality is 98/100. I'm using the wcid network manager instead of defaul gnome one. I'm getting lots of packet loss and performance is very bad. The connection is practically unusable. I've tried installing the compat wireless backport package but that did not work at all.

I did a clean install of Ubuntu 11.04 64bit and the start up time is abnormally slow. If I start up the computer and don't press anything, the start up time is 30 minutes but it usually doesn't start up at all. It just boots into a purple screen, no splash, then it sits there and the computer doesn't have any loading lights flashing.
I had a similar problem with 10.10, but I assumed it would go away when I did a clean install of 11.04.
I can't get a read out of what's going wrong because when I press Esc it doesn't display anything, though weirdly it can sometimes get the start up process moving. I have also found that pressing enter really fast can sometimes help and something that seems completely oxymoronic, if I press the power button while it's starting up that can make it work, but nothing works every time.

The problem is I have a wireless Belkin router which I can connect to, but after being connected for a few minutes the net disappears (cuts from the router) and my laptop will have to reconnect again to the router for internet to work again. After a few minutes (or seconds in some cases) the connectivity loss will happen again over an over.
How to fix this problem or some things I can try, I've tried updating to two different firmwares, two different channels and resetting the router. The biggest problem I find is that this happens on both my laptop, another laptop in the house and also my tablet PC but doesn't happen on two other laptops in the house, I've also tested with windows 7 and Ubuntu with my laptop.
My laptop wireless card is Atheros AR9285 802.11b/g/n WiFi Adapter

I am running Slackware 13.0 on a old dell dimension 4500. The install went fine. sound worked, graphics where good. Everything was going perfect. until i worked on wireless.i have a realtek rtl8185 wireless chipset card. I got the wireless. Linux wireless driver. It worked on both Mint 5.0 and backtrack 4.0.so I untar the file. cd to the dir and type make then make install and reboot. like I have always done.
I was having to fight with wpa_gui and finally got it working but then it would go in and out on the connect and disconnect feature. so I tried using iwconfig. did not get muc luck with that either so i installed wicd and finally got a ip address after fighting with it would give me in a ping like 75% packet loss. so I read a lot of post and try to find stuff before I post. and while reading I learned that you guys normally ask for info on the hardware and software so here you go. but I will say first that I read about adjusting the mtu to fix packet loss, I showed some of the changes I made in it around the pings I know it is a mess I am sorry I tried to make it readable. if you need more information let me know. I cant get online using a web browser or if I can only for one or two pages. any help would be great. thank you.
Code:
bash-3.1# ifconfig
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
inet6 addr: ::1/128 Scope:Host

Excited at seeing the new features in 10.04, I clicked the Upgrade button tonight. I am now really regretting it! Problems:
1. My screen resolution should be 1280x1024 but the System>Preferences>Monitors control panel only shows 1024x768.
I think I have onboard Realtek graphics. Do I need to install proprietary drivers? Everything worked fine out of the box with 9.10!
2. The sound isn't working. Again I think I have onboard Realtek sound, and again it used to work fine without any intervention from me...
3. Although on first startup wireless networking was working fine, I restarted to see if that would solve the display issue, and wireless networking stopped working too!
I have an RaLink wireless card.
When I used Grub to choose 2.6.31.20, I got some error messages at startup (e.g. mount couldn't mount /dev), but then it did eventually start up and the sound and wireless networking are working again. But the resolution is still not fixed. It is now offering 1152x864, which it didn't previously, but no 1280x1024 (my screen's native resolution).

I am recently trying to get a steady wireless connection running. I am currently using the default settings/driver Fedora 13 is stocked with. As my internet browsing is somewhat up and down in load times, I decided to check in a video game which is generally a good test for me. haha I am harshly spiking and cannot find the source of my problem so my guess is a driver issue.
lspci | grep Network:
Code:
Code:
It is is seemingly right, my Windows 7 harddrive works just fine, this is just one last of the few issues I'm having from fully formatting my winblows HD to use as Linux storage.
I cannot find any native AR5008 Linux Drivers for my card and it has been a frustrating day. I guess I'm not cut to be a network analyst just yet.
System specs:
ASUS P5Q SE/R
Intel Core 2 Quad Q9550
4GB DDR2 667
Gigabyte GTX465 1G
TP LINK TL-WN851N Wireless card

I have a Acer Revo R3610 nettop on which I installed oS11.3. It has an Atheros AR5001 wireless network adaptor.I'm getting very bad latency and throughput on with this card. In comparison my Thinkpad with Intel card achieves at least 10 times the throughput from the same location. Also when I boot my wifi will come up authenticate and then a few seconds later disconnect and reconnect. I've tried updating the kernel to 2.6.35 as one of the fixes was to improve the performance of the ath5k driver. I'm using wpa2 authentication.
Here are some details:
Code:
mediacentre:~ # /sbin/lspci -nnk
00:00.0 Host bridge [0600]: nVidia Corporation MCP79 Host Bridge [10de:0a82] (rev b1)
Subsystem: Acer Incorporated [ALI] Device [1025:0222]
[code]....
Is there anything else I paste that will help determine the cause of the bad throughput. Browsing the web or copying files across the network is bordering unusable.

I haven't done Linux since before it had Wireless support, and have never had to tinker with network settings, so I am at a loss.My searching may be weak, but when I tried, I found nothing relevant except to determine some of the things usually asked for in threads of this nature.The symptom is very slow connection when using wireless, but it does fine when I hardwire it. Using Windows 7 on the same system it flows nicely.

I have managed to compile and load the RaLink drivers for my wifi card and get an internet connection.My problem is that when I do a broadband speed test on using chrome I get about 1.5 Mbs and on my laptop (Windows 7 meh :-( ) its closer to 7Mbs. I was wondering if there are any other settings I can modify or tweak that could potentially change to improve this. or maybe a better way to test the through put of my connection?I downloaded the latest drivers for my device from Ralink and compiled new module, but I get a little confused on what settings to do and where it reads any configuration information from.
Also this may be off topic or thread, if so I apologise, but I am sure there is a quick answer to this and there is a lot of different information out there on where and how I load my new rt3562sta.ko module into the kernel on start up. As currently I am calling insmod on it manually every time I start up then the Network Manager picks it up and connects.

I have an Intel Celeron 2.80 Ghz processor, 1GB RAM, GeForce 8400 512MB video card running Ubuntu 10.04.When I open VLC it takes 15 to 20 seconds to open. I just setup another computer: Pentium III 1.1Ghz with 256MB of RAM with Crunchbang Lite, and VLC opens in less than a second. No problem with VLC on my computer at home.
I have tried uninstalling and reinstalling VLC but no change.No errors from the command line.What could cause VLC to open slowly on only one computer?

I have had an extremely slow startup (upwards of a few minutes) for awhile now, and nothing seems to work to fix it. Regular boot time is far slower than it should be, and the time of logging in to a workable desktop is just really bad. I will log in, and then I will either get a blank desktop screen for awhile or an all black screen until the desktop will fully load with errors from gnome-panel and AWN not starting up automatically.Some of the fixes I have tried:
Disabling floppy from bios
Downgrading gnome keyring
Removing gnome* and gconf* from the home directory
Putting this script in /etc/init.d
#!/bin/sh
echo "nameserver 0.0.0.0" > /etc/resolv.conf
Here's my bootchart and a link in case the upload has problems http:[url].....

I have an Acer Aspire 5920G laptop, which uses Intel PRO/Wireless 3945ABG wireless card. I upgraded from 11.3 to 11.4 using live upgrade and after the upgrade wireless internet became really slow. Now I'm back to 11.3. I experienced the same problem with speed when I was choosing Linux distro - first I tried Fedora and Ubuntu and both had the same problem, but when I tried openSUSE 11.3 it worked fine. With 11.4 Network Manager showed that signal is at 100% and it connected to router with normal speed, but when I tried downloading a file I got 30kB/s max, while I used to get 1,1 MB/s with windows and 11.3. I also noticed that right after boot I got decent speed, but it only lasted for less than a couple of minutes.
Since 11.4 should have better or at least the same driver as 11.3, problem is probably with configuration, but I am using NetworkManager, so I have no idea what could be wrong.

Whenever I start a text editor, such as kate, kwrite, gedit, it takes at least 10 seconds to start up.This on a PC with 4 cores and 3GB RAM.I know that these text editors should start up much faster, like, I click the launch icon and it should already by there.But instead it's 10 seconds waiting and then the editor is there. Why, what's it doing during those 10 seconds, and most important, how can I fix this?

Since upgrading from Heron to Lynx (64 bit) Gnome is slow to start. It seems like it is waiting for some sort of automated timeout, since the harddrive stops in the middle of Gnome startup (after login) for around 10 secs or so. Is there a logfile of the startup-sequence somewhere that I could look at and/or post here?

I don't think any changes have been made to my laptop, but it suddenly loads Ubuntu extremely slowly. The time it takes to get from the Toshiba boot screen to the Ubuntu Log-in screen takes easily 20x as long.
Has anyone else been experiencing this kind of lag or have any ideas where to begin?

I have a Dell Vostro 200. Have been running Ubuntu on it for 18 months - no probs. Recently it became very slow to boot. 5-10 minutes before Ubuntu startup screen appears. Have installed Ubuntu 10.10 (on a reformatted hard drive) today. No change. It's fairly certain to be a hardware problem but I don't know where to start.

I've been using Opera 10.11 on two different computer systems, two different locations (work & home), and two different Slackware versions (13 & 13.1 current). Opera 10.11 runs very quickly on both. After upgrading to Opera 10.60, I now find that linking to new web pages takes 5 to 10 seconds, but returning to a previous page is almost instantaneous.
I've tried installing 10.60 using slackbuilds and Opera's installer - both give the same results. I've since reverted to Opera 10.11. why it is so slow to open web pages? Opera 10.60 for Win7 works great, so what happened to the Linux version?

The nfs-client service isn't starting after boot up. This is causing problems with the user as they cannot access the remote folders on the server. The PC is a Thinkpad X60s with oS11.3 and KDE4.4.4. The problem started about a week ago after some updates (new kernel update, kde4 updates and some system files) were applied on the laptop.
After logging in none of the remote folders are available. Checking the nfs-client service under Yast>System Services (Runlevel) shows the nfs-client service is not running. If I enable and start the service I get the pop-up confirming the service has started but still cannot access the remote folders even after issuing a mount -a. Opening Dolphin just opens a blank grey window which needs to be terminated.
Trying to restart the nfs service using su -c 'rcnfs restart' sticks at Starting NFS client services: sm-notify Just leaving the PC for 10-15mins eventually sorts itself out and the remote folders become visible. I cannot see anything obvious in the logs so am a bit stumped.

I installed fedora15 on my laptop. and after an upgrade, with the kernel 2.6.40-4.fc15.x86_64, my fedora boot is taking almost 10 minuts.....Its take so manytimes to boot. does someone knows why?I installed jdk, eclipse, glassfish, firebird and postgres for my workspace.....
---------- Post added at 11:16 AM ---------- Previous post was at 10:55 AM ----------
ok I I figured out why the long time to boot.I have here installed glassfish and I add a Line on /etc/hosts like that:
Code:
[vinny@vinny-fedora ~]$ cat /etc/hosts
127.0.0.1localhost.localdomain localhost
#127.0.0.2 vinny-fedora
::1localhost6.localdomain6 localhost6
127.0.0.1 vinny-fedora
If I comment the last line, the starting is normal. But without this line I cant start up Glassfish. is there another way to sat my hostname?
