Ubuntu Networking :: Lost My Wifi All Together / Get That Back?
Jun 20, 2011
I was running a patch of my wifi connection and now i have NO wifi at all. I am totally lost right now. i have been running throught all the threads but nothing is really working. Is there a way do a full system restore (like windows) that will undo all my mistakes? my wifi has always worked until i screwed something up!
I am running ubuntu 9.1 on a Dell Dimension 2400. After installing ubuntu on the pc, it was automatically recognizing my router and connecting to the internet fine via ethernet. Then, my roommate unplugged the router and it won't recognize it. I can't access my router settings, and ubuntu is recognizing it as "inactive" but every other computer in the apartment runs fine. My PC uses a broadcom ethernet controller, and my router is a Linksys wireless N.
I upgraded my netbook (HP Mini 5101) from 9.10 to 10.04 yesterday. Everthing (including bluetooth) seemed to work, as it did before. Today I tried to install a 2.6.35 kernel from maverick backports (the kernel ppa), but it didn't work for me and I removed it again. Now my bluetooth is gone (bluetooth applet does not show any devices) but wireless still works.
I already tried to remove and reinstall the driver package via apt-get (sudo apt-get un/install bcmwl-kernel-source bcmwl-modaliases) but nothing helped. code...
i have a acer aspire one (zg5) with a 2 week old installation of unr. shortly but not immediately following my last update my wifi no longer functions. when i go to the network connections tab in my toolbar it does not list available wifi networks. does not apparently recognize wifi capability at all. but the wifi worked right off the rip on new install.
Reading recent posts, it seems that 11.04 has seriously screwed wifi. I have an Advent QRC430 laptop which worked perfectly until I upgraded to Natty. Now wifi is broken. The wifi driver is rt73usb. When I run lspci in terminal, no wifi card is listed. Running rfkill shows wifi hard blocked, but the switch on laptop makes no difference. I've installed and run Hardware Lister - this shows wireless interface "has been disabled"
I turned down my txpower with the command: sudo iwconfig wlan0 txpower 3 Which works to fine turn down my broadcast power from the default value of 15 dBm to 3 dBm. But it is reset every time I restart Ubuntu 11.04 to the default value of 15 dBm. How do I save my modified txpower settings so they don't reset after a restart? It is really annoying having to re-enter the command every time I reboot my computer!
I was going fine yesterday and today I logged on and it seems as if my packets are being bundled up and sent at once, because websites spend ages loading, then all load together at the same time, my IRC lag bar increases and increases then pops back to 0 around the same time the web finished loading.
I am running Ubuntu 10.10 Netbook Remix on a Toshiba Netbook NB300. After performing an upgrade I find myself unable to connect to my wirless network and have lost the wifi icon in the task bar. Ethernet connectivity is however working.
iwconfig shows: wlan0 IEEE 802.11bgn ESSID:off/any Mode:Managed Access Point: Not-Associated Tx-Power=20 dBm Retry long limit:7 RTS thr:off Fragment thr:off Power Management:off ifconfig shows
I need to take to bring back wireless connectivity to my netbook and restore the wifi icon to the task bar.
Alright so I lost a sd card that I had uploaded to my comp before it crashed but I wiped the card before I lost it and I want back what was on it..I have ran testdisk and photorec and it has only brought me back 5 or so pics, but when I search the card in deleted files through either program it lets me see the file names, and when I try to save it the computer doesn't read the jpeg file when I go to open the recovered file.
I have lost wifi access with the upgrade to 11.4.Previously, the receiver icon showed on left click a menu of available networks, and on right click, available network by network settings for editing. The menu also included enable wireless connection and enable wired connection. I have wireless enabled.
But with the upgrade, the same menu appears on left click or right click, and they both show a greyed out "wireless disconnected" tab, so you can't connect from there, the tab is disabled. There's also no place else to go to find available networks or to lock into one. There also does not seem to be a place to find wired networks either.I installed my wifi network in it, and put in the correct password and set it to come on automatically, and 3x restarts did not yield any changes. Apparently network finding is disabled in this version or at least my copy.It isn't the computer: I'm on line with it now on the Windows XP side.
This is doubly problematic because if I can't get on line, I can't download a fix, and even if I could by downloading it to the Windows side, it is probably a binary with some very scripts and meticulous BASH coding or tarballing something else that I have no idea how to do even with a walk through by an expert because most of the time the experts assume I know as much about using a Linux terminal and code as they do, and I basically know absolutely nothing, it is all Greek to me from the point at which they say "open a terminal." "Go to root" might as well be said in Chinese as far as its usefulness to me. What is the plan here? A complete redo from the get go?
I am happy with ubuntu it's cool, but I want to go back to windows. I lost my windows cd. So I made a blank disc with an iso file. But the problem is. When I try to keep it inside my computer and restart it won't load. I think grub has something to do with this.
I have a harddisk which is partiotioned in C & D. I've installed WIN XP on C and WIN 7 on D. Then I installed Ubuntu 10.04 on D beside WIN 7. Now I can't access to WIN 7 and also to drive D in XIN XP and in Ubuntu. What can I do to get back WIN 7 and drive D ?
Login in problems: I was trying to fix the brightness on my toshiba T130 Satellite laptop and found these instruction [Note: I did not try XRANDR option] If backlight control doesn't work with the 'XRANDR' option above, use this code...
Safe the file, run 'sudo update-grub' and reboot.
Credits: https://bugs.launchpad.net/ubuntu/+s...id/+bug/392948[/INDENT]http://www.linlap.com/wiki/toshiba+satellite+t130 However after running these instructions and rebooting my laptop I lost the GUI, and do not know how to get it back. If it helps the loader screen with the 4 dots has gone slightly skewed, and I've downloaded the most recent update changes.
I can get GUI through recovery mode and running it in failsafex, but I don't think this is a good solution.
I'm using Windows 7 and Ubuntu in two differents partitions in my hard drive. I was on Windows 7 and decided to reboot. When the grub screen should have appeared, instead the computer rebooted itself. It continues to do so. I put Ubuntu 10.10 Live CD and it keeps "loading" forever, but doesn't hang. In the console, it said something like "input/output" error. I tried with my Win 7 DVD and it was the same: it doesn't reach the part where it shows the menu with all the installation options.
I tried with Gparted and it loaded fine. It showed all my partitions, but there wasn't (I think) more that I could have done with it. I tried then user Super Grub Boot. I finally could enter Ubuntu. Everything is fine except that it doesn't show my Window partition. It's like it doesn't exist anymore, so I can't backup my files. Now, I haven't tried loading Win 7 from Super Grub Boot (I'm going to do it just as soon as I post this), but this is pretty weird. Anyone have any idea what is going on and what can I do to this this?
I had everything backed up so it is no great disaster, but drop box lost a lot of my files. Some of the folders with missing files now have thumbs.db in them, but when you go to the dropbox site, you don't even see that.
I had thought about using dropbox as my main backup solution. That would be a big mistake.
I installed Ubuntu 11.04 on a usb stick and have been running it from there. I was messing around with the "Login Screen" utility and changed the session choice to "User defined session" (or something similar). I thought this would allow me to pick the session to use (Unity, Gnome) but that was wrong. So right now, when I login, I have a blank screen with no menu bars. If someone could give me the commandline command to run the "Login Screen", I should be able to switch it back.
So I am working on a clients PC, and after I saved their data on an external hard drive I left it plugged in while I reinstalled Windows for them.....I HATE Windows. Stupid OS doesnt know any better than to just go deleting everything. Ubuntu would have known better than to delete multiple hard drives like that.
Anyway, please tell me I can salvage this data for my client? It was probably just reformatted. The data should still be there right?
I have a problem I don't know how to solve. Today I bought a netbook and while waiting for the new Ubuntu Unity release to come out, I thought of trying out Crunchbang instead of Windows that came with it. Browsing on my Ubuntu desktop machine, I found a guide for making Crunchbang live USB stick, and i followed the procedure. However, I made a very stupid mistake. The guide said I should enter the command: sudo dd if=/path/to/iso/crunchbang-10-alpha-01-openbox-i686.iso of=/dev/sdX bs=4M;sync
where "of=...." part should be replaced with the name of the HDD. I forgot that I have an external HDD mounted and mistakenly copied the data to it. After this, I cannot see the content of my external HDD anymore. Instead, i have this 620mb large Crunchbang-install device.
I know what I did was stupid, but is there a way to get the content of my HDD back? I have some valuable data on it.
I was trying to free some memory as my /var was about to fill.I went to Add /remove software and ried to remove some of the unwanted software and it asked for dependency and i clicked ok.After a while i saw some of my aplication like Evolution,Empathy blackening and i killed the Uninstallation. I was sure by time that something wrong has happened and i did not switch off my monitor so that i can retain my application.I tried lot to increase teh /var so that i can update my yum and install some lost application but allin vain i tried Gparted which can only decrease the size . I had 40 GB unallocated space so i tried to boot from Live Fedora 12 DVD and was able to see my all the files and filesystem. All my data in /home was intact.I tried to go to grub and went to boot hte kernel and Initrd and was able to go to #root but again was not able to update the system as network was missing.The SYSTEM was Not booting and stuck in between. Tried to change the /var to var1 copied /var content to /var1 and made changes in teh /etc/fstab still did not work ,so finally went to repair with Live cd but could not get "Linux rescue" anywhere not even to upgrade option so finally installed the New linux without touching / and /home partition rest were deleted and formatted for new instalation.Now i could not see my data in /home directory although i could see data in /root(old) and all ..i am now lost ..my data is nowhere ..please help me.I can only see /home(old) but it says empty and shows 6 GB unused and 3.3 GB used when seen in Gparted .
I shut down my laptop this morning and headed to the office and fired it back up to find that I no longer had the use of any of my usb ports! messages are saying that the ports have been disabled. curious if an update broke something? the ports have been working fine, I use a usb mouse instead of the touchpad most of the time.
We have 2 computers connecting the wireless network. I reinstalled the linux machine and lose the saved wifi password. I don't have the router access password. I am looking at other computer running Mac and see wifi password as xxxxxxxx. Is there a way to see what wifi password is (from the Mac computer)? The "show password" button is disabled.
I've just had a phone call from an 8.04/win xp duel boot user who has lost the boot entry to xp after a 8.04 update. I guessed at a system upgrade but she checked and is still on Hardy. They write and only have the xp for printing as there is no Linux support for the cannon printer. Using the printer is important. I've said I'll pop round and try to sort it out. Any ideas how I can do this. Update grub in recovery mode maybe or if I need the command line what should I try? I'd like to know before calling as though I'm not quite a novice this isn't a problem I've had to cope with since grub 2 beta ( didn't solve it then either an am still using 9.04 ). Hacking legacy will be new to me. As this is a writers machine with all her work on it I'd regard it as a critical pc, don't want to mess things up for her.
