Ubuntu Networking :: Totally Erratic Wireless In Maverick
Nov 2, 2010
wired is fine and fast. Wireless connects but connection goes from 100% to 53% at random, making the connection pretty pointless to use.Probably get fixed in an update. I have tried uninstalling network manager and using wicd. No luck. Well, luck, as in I could connect, but exactly the same as Network Manager.The card is a Realtek RTL8191SEvB. Machine: Toshiba Satellite Pro L510. Any takers? Would really like to get this happening as everything in Maverick is working great apart from it.

I've upgraded to Maverick but now I cannot get my wireless card working. In Lucid it didn't work out of the box, but worked perfectly by wrapping the Windows driver with ndiswrapper.
I noticed when I installed Maverick that wireless is enabled in Network-Manager and it gives me the option to create a wireless network or connect to a hidden network but it's not discovering/showing any of the wireless networks in range! So it seems as though the card is being recognized but the driver isn't working fully...? I tried wrapping the windows drivers, but that didn't change the situation at all.
Details of my system:
Code:
Ubuntu 10.10
2.6.35-22-generic x86_64

I'm using Maverick and since yesterday, my wireless hasn't been working. It was working before with Maverick and I don't recall doing any updates that might have changed wireless configurations.
By "doesn't work" I mean it doesn't recognizes any networks, as if the wireless was turned off (there's this button on laptops, but it's turned on). I had that problem some time ago, but rebooting solved the problem, which, now, didn't.
My laptop is a HP dv6420la.
Where to start?

After hours of searching and trying different methods I am still unable to get my wireless going.. I have tried the PPA method from Chilli and looked through craneman's thread. I have installed the proper realtek driver and done modprobe for the device to no avail. In Additional drivers nothing shows except for my ATI drivers.
dnkbd@losnix:~$ ifconfig
eth0 Link encap:Ethernet HWaddr 00:1e:33:bd:d5:10

I just installed 10.10 for netbooks, and apparently it's using the RT2800PCI driver for my wireless NIC in my EeePC 901. That driver is causing havoc with my school network, I keep getting disconnected, and loading websites is really slow.
Now I know that 10.04 uses a different driver RT2860 which seems to work far better on this network.
How to change to the driver from lucid. Or does anyone know of an even better solution? I've heard rumors about something called ndiswrapper...

When booting from the netbook USB, there are two wireless connection stages:
the first appears at the "TRY/INSTALL" selection screen, and after supplying the keyring password, the connection appears to succeed.
the second appears on the desktop, after selecting "TRY"; the keyring dialogue appears & seems to work, but then the network login dialogue pops up, and refuses to connect.
Both my Acer machines connect to the same AP under Maverick and the EEE PC works in Lucid.

This is a fact I have to share with you. I've tried it on liveCD version, and also have tried to fix the problem, but nothing worked. I even installed ndiswrapper, but the Windows drivers didn't solve the problem:
- the system sees the card (lspci)
- the card doesn't see any wireless network (iwlist)
- no command line manipulation helps (iwconfig, ifconfig)
Conclusion: the network manager is out of order.

Does anyone else experience this phenomena? It only happens on one of my PC's, my Compaq Presario M2000 laptop.The icons for various applications in the top panel load eratically on boot up. E.G sometimes the wireless icon doesen't appear , sometimes it loads twice. Sometimes the Sound Preferences (the speaker icon) is missing, Evolution Mail etc etc. Even the shutdown icon occasionally is gone. It sees limited to the ones on the right side and doesn't seem to affect ones such as Firefox that I've dragged up there myself. It doesen't happen every time, I'd say about 20% of boot ups this happens.

I just upgraded from 8.04 to the lucid beta (yes I was slow to move on that), and chromium's scrolling is HORRID! It jumps and skips both when I use the mouse wheel or when I drag the scroll bar.
Any ideas? Firefox scrolls just fine. It makes using chromium very unpleasant because any time I have to scroll I feel like I'm back in 1992.
I did some searching and found lots of complaints, so I thought I was close to an answer until I looked at the date, it was late 2008/early 2009 when this was an issue.

I've been having some problems copying files to USBs. If I'm copying a large (100MB+) amount of data, at random points the transfer will just stop for 30+ seconds before continuing. Sometimes it doesn't start up again at all. Consequently, the write speed drops to less than 1MB/sec, sometimes as low as 100 KB/sec. I do not have these problems on Windows 7, where I achieve speeds of ~16 MB/sec easily. I have had the same results with several USBs (2-32 GB) on several file systems (fat32, ext2) with several different computers running fully patched versions of Ubuntu 10.04, which suggests the problem is related to the way the OS accesses the hardware.

I built a RAID5 storage array using 'mdadm' on 3x WD Green 1TB hard drives. I used the Disk Utility GUI to create the array and it took about 24 hours to build. When I started copying files to it I noticed it performed at decent speeds for a while, then got really slow, the sped back up. Just for laughs I ran the Read-Only Benchmark function in the Disk Utility and got a graph that would even confuse stock brokers.Any thought on what the issue might be? I tried searching around for an answer, but most people are only affected by wirte performance issues not reading.

Sometimes the screen displays four miniature versions of itself. Sometimes there is no display of the pre-boot message. When normal boots occur, often the screen display disappears entirely and irrevocably after about ten or twenty minutes.Sometimes everything behaves well with no troubles.

I upgaded my system last weekend with a Gigabyte GZ-X58A-UD5 motherboard, i7 processor, ASUS EAH5770 video card, and 12 GB RAM. Sound has been erratic since then. It generally works for a short time after a reboot, but after awhile (within a few hours) it stops working properly or even completely. I've tried several different settings in /etc/modprobe.d/alsa-base.conf, but nothing I've tried helps.
I am running Kubuntu 9.10 64-bit.
Here is the output of aplay -l code...
I don't have anything connected to the HDMI connection on the ATI video card, and only inputs on the M Audio Delta 44 card.

I have a dv7-4172us laptop from HP, a new laptop. It has AMD Phenom II N950 -64 bits processors. I am running LiveCD version 10.04 LTS 64 bits in "Try Ubuntu" mode. If I type type fast, the character cursor (not the mouse pointer ) moves away randomly, like a few rows up from present typing location. Sometimes, something else, like another application scrolls it self while I am using Gedit to type this posting. the cursor jumps here and there. Typing on this forum page also produce the same erratic cursor jumping problems!
I also disconnect my optical wireless USB mouse, and still have the same erratic cursor problem. I do not have the ANY problems with Win 7 -64 bits. This is a serious problem. It will render any laptop useless with Linux I so look forward to using Linux.

I am having a problem with how my windows behave.My windows will maximize and minimize over and over, scroll bars will scroll to the bottom/right automatically, if I click a menu it will pop up for a fraction of a second and then go away. It makes my desktop almost unusable.I can't figure out if this is a mouse or video issue. I have a radeon 9500, and a logitech LX3 optical mouse. BTW, this problem is present in other distributions on my system. I am running KDE. It even does this on the livecd.

Upgraded via Update Manager from 9.10 sound-previously-working-just-fine-system. Now, for example, running any audio-producing app (Rythmbox is a good example but its the same for anything including out of a VirtualBox XP install or with MythBuntu): The main volume control functions, but goes from muted to full volume in just 4 steps; raising it higher has no effect. It gets stranger: in Alsamixer or gnome-alsa-mixer I can see that lowering the desktop volume control to mute causes Master, PCM, Front, Surround, Center, LFE, and Side all to go to zero. Raising the desktop control one step causes all of these but Front to go to 100% instantly. Increasing the desktop control by a few more steps causes Front to step to 100%, after which no further volume increase is perceived. It's as if each step in the desktop volume equals some 25% of the Front setting, and 100% of the others. The audio setting in System, Preferences, Sound, Hardware is "Analog Stereo Output."
If I click 'Mute' on Master in the mixer then all the speakers mute, but unmuting Master does not unmute anything else. Only after I move and release the mouse-down state from the master volume do the other channels unmute. The volume control in Rythmbox, on the other hand, works seemingly correctly (maybe its going thru Pulseaudio?) And as an aside, why are there no controls for Pulse if it sits on top of ALSA?
I'm really confused by this, as all of it work as "expected" while running 9.10. Here is some output from this system (an ASUS M4A78T-E):

So, I use Ubuntu 10.10 on an old Dell laptop as the router for the house. It shares its Vodacom 3G with the rest of us, via the network port of the laptop. This works fine. We can all surf to our hearts' content.I can also VNC into the desktop of the router machine if I ever need to accomplish X, Y or Z on it, which is handy.However, I cannot for the life of me SSH in, or connect to the MySQL server that also lives on that machine. This is a pain.What I want to do is set up a database on a remote server, and then tunnel in via SSH. I'm trying to test that configuration using local machines on my network. My desktop machine happens to be XP, and I'm using Putty to try to initiate the SSH connection, but I keep getting a message saying NETWORK ERROR: CONNECTION REFUSED.

I'm not sure what to call the semi-transparent sidebar with a random collection of unconfigurable icons, but I don't think it's working properly.
1. When I move my mouse to the left edge of the screen, it doesn't always appear. Sometimes I have to move my mouse back and forth, back and forth, several times.
2. What it's doing right now is even worse... it appears, but as soon as I move the mouse a *little* bit to the right to actually click an icon, it disappears.
What is causing this? Surely it's a bug? How do I make the sidebar the absolute top priority for the screen edge so that it always catches it and appears? how do I configure it? I can't right-click on the sidebar itself. I can right-click and remove some icons. Other icons, like the grayed-out (but still active) "recent files" thing cannot be removed.

I just installed Maverick on my netbook (Lenovo S10-2) and am having network issues. I had to plug in to the ethernet port before installing to get extra packages and updates. I was going to get the Broadcom STA wireless driver after it was complete. Installing the OS worked fine and it downloaded everything it needed to. But when I restarted, it didn't recognize when I plugged in the ethernet cable, making getting the wireless driver impossible. I reinstalling twice. Same story.
I tried different cables and none of them worked. Also, I tried to compile the wireless driver myself so I could put it on without having internet.

I have followed the guide posted here: https:[url]....I stuck am at "Under the desktop menu System > Administration > Hardware/Additional Drivers, the STA drivers can be activated for use"I can not navigate to this menu because it does not exist in my build. Is there a way to circumnavigate this?

I recently upgraded from Lucid to Maverick, and I noticed that a new error message caused by a "cp" command call, including the hard links option. Fortunately, I kept the last Lucid kernel (2.6.32-25), so I could check the different behavior with booting successively on each kernel. Here are my configuration files:
On the server (192.168.1.2):
/etc/fstab :
UUID=... /mnt/Backup ext4 defaults,errors=remount-ro,relatime,async 0 2
/etc/exports :
[code]....
If I check permissions of /net/Backup/Folder2 from the client, I get :
owner = nobody (Create and Delete files), users (Access files), others (Access files)
cp -alR /net/Backup/Folder1/* /net/Backup/Folder2
- under kernel 2.6.32-25: no problem
- under kernel 2.6.35-22: all the subdirectories are created, but all empty; moreover, I get as many messages as number of files from the source:
"cp: cannot create the link ...: operation not allowed"
I can copy manually any file to /net/Backup/Folder2 from the client. Why the behavior has changed from kernel 2.6.32-25 to kernel 2.6.35-22 ? Should I modify the permissions or the way the mount is exported with options like "(no_)root_squash", "all_squash", or "anonuid", "anongid" ?

I had Bluetooth PAN network working fine in Lucid. For some reason (mainly hardware) I had to upgrade to Maveric. After that my Bluetooth PAN network stopped working at all. I found out that server host do not even expose any PAN or GN profiles. The only profile it exposes is "Hands-free audio". Setting PAND_ENABLE=1 in '/etc/default/bluetooth' did not have any affect. I attempted to start PAND in listening mode and it exposed PAN profile but any connection was unsuccessful. When I try to connect to any other PAN profile it also had no success with 'Permission denied' message.

I upgraded to Maverick over the weekend from Lucid, and at school yesterday, I could no longer connect to the campus wifi network in my office. I have no problem connecting to the wifi network at home, and my phone still sees and connects to the campus wifi network, so I think the problem is with my laptop (Gateway T-6345u), which doesn't even detect the campus network. As of last week, it connected automatically, and now it can't even see the network.

I am having some trouble getting one PC (Windows XP) to see the printer attached to the other PC (Ubuntu). I went to System > Administration > Printing in Ubuntu and did the following: Checked the box next to "Publish shared printers connected to this system" Checked "Enabled", "Accepting jobs", and "Shared" in the properties of the printer. I have an HP Deskjet 5650. Is there anything else I need to be doing?

This week I did a fresh install of Ubuntu 10.10 on a newly assembled PC. The hardware I am using is below.
My wife has a Macbook with built-in Wifi connected to our Linksys router. Previously, the connection would drop 0-2 times a day. She would turn off Wifi on her Macbook, turn it back on, and it would reconnect immediately.
Since getting my Ubuntu PC, these disconnections have become more frequent, every 30-90 minutes. They effect both computers simultaneously. And now, I MUST turn off Wifi on my Ubuntu box to regain the connection. Switching it off and on with the Mac doesn't help. Unplugging the router doesn't help. I have to run upstairs and uncheck "Enable Wireless" on the Ubuntu Network Manager outlet.
The connection doesn't seem to drop if the Ubuntu PC is sitting idle. But it can happen with web surfing, Samba file transfers, or torrent downloading.
I noticed that Encore has a linux driver for my card called RT2860. It looks very difficult to install. Ubuntu automatically uses RT2800. So I don't know if this could be a driver issue. Also, shouldn't my bit rate be more than 1Mb/s? Both the router and the card are 802.11n. Are the dmesg errors something to be concerned about?
Machine Brand and Model (PC/Laptop): Self-built Desktop. AMD Phenom, Gigabyte motherboard. Router Brand and Model: Linksys Wireless-N Broadband RouterWRT160Nv2. (I already updated the firmware to the most recent version)

I do not have access in my laptop with ubuntu 10.10 maverick 64bit installed. I deleted network manager when trying to set up a static I.P follow the guid on this page www.liberiangeek.net/2010/09/setup-permanent-static-ip-add I've googled around. The methods suggested to solve it have not been useful in my case. I tried to the method by a user on this forum

sudo ifconfig eth0 up
sudo dhclient eth0
If you have wireless it's a little more complicated, but if you have an unsecured network (no WEP or WPA) and your wireless interface name is say eth1, and your wifi network essid (name) is "mynetwork" it wo
uld be something like this:
sudo ifconfig eth1 down
sudo iwconfig eth1 mode managed essid "mynetwork"
sudo ifconfig eth1 up
sudo dhclient eth1
