Ubuntu Networking :: High Throuput Mode Aka 11n Aka 801.11n Mode On Airlink101 AWLL6075?
Sep 21, 2010
I ordered this USB 802.11n dongle for about $10 and am having problems.I found a firmware related bug (Bug #595455) that keeps it from working out of the box and got around that. I put the right firmware file in the right place and CAN CONNECT TO B or G Access Points.hen I put my AP in N-Only mode, I can see the network, but cannot associate. With the AP in mixed mode I can Associate using G.The most interesting thing I found was something that had very
few google hits (like 4). In the dmesg output after associating I see the message:
Successfully associated, ht not enabled(0, 1)The most interesting thing about this is the (0, 1) at the end.I don't know what that means but it seems like a clue as to what the problem is.This device uses the realtek chipset 8191S, there are conflicting reports on this, but all the reported possibilities seem to use the same driver from realtek (rtl8712_8188_8191_8192SU_usb_linux_v2.6.0006.2010 0625).Here is some random info:
Dmesg output:
[85082.620027] usb 1-3: new high speed USB device using ehci_hcd and address 6
[85082.754586] usb 1-3: configuration #1 chosen from 1 choice
[85082.755456] ==>ep_num:4, in_ep_num:1, out_ep_num:3[code]........

Below is a print out of my partition Table from Fdisk, in Cylinder mode, Sector mode, and then in expert mode?
Why in expert mode does it look like Partitions 2 and 3 share the same sector / hd / Cylinders? Is this OK?

Now that I have setup a proxy server, as a next step I want to run it in fail-over high availability mode, so that if one proxy is down due to any reason, second proxy should automatically be up and start serving requests.

Kernel 2.6.21.5, slackware 12.0
When you do 'man bash', you'll see some words are highlighted. I'll say that the video card has used high intesity in these instances. How do I disable this video card capability? Can this only be done by recompiling the kernel? Of course, I am talking about the text consoles, i.e., the video card in text mode.

I attempted to install Catalyst 10.11 for my ATI HD 2600XT and the system now only displays lines and a large block of pixels where the mouse would go. CTRL-ALT-F1 kills the system and does not provide a command prompt. This is a single installation, not dual-boot, but there is no Press Esc to access the Grub menu during startup so I cannot choose safe mode. I attempted to get into Recovery mode using the flash drive that I used to install the system and it tells me there is no Recovery kernel (I used the 64-bit Desktop installer, not alternative). Does anyone know an alternative to get into the Grub menu other than ESC during bootup? Alternatively, do I need to download the 64-bit Alternative ISO and create a new boot disk with it so I can access Recovery mode? Is there something else I'm not thinking of?

I installed ubuntu 9.10/9.04 on my usb key as live image couple of time. I have trouble when I try to install wine on my usb key. I am wondering what is the difference if I install my ubuntu into my usb key directly? will that be slower compared with live CD mode? I guess live CD mode may use memory as part of harddisk to save temepory files and normal usb linux installation won't do this for me. Is this true?
If so, do I have a choice to point my tmp directory to system memory area?

When I first installed ubuntu 10.10, the display was for some reason tinted green and shifted a few inches to the right. After experimenting with the resolution preferences, I eventually got it to a large resolution (1280x720 ... or something like that) yet is was quite blurry. I found out that the problem was with my monitor after I switched it to TV mode, then back to PC mode. It became perfectly clear! All I had to do then was adjust the screen positioning by shifting it left a bit.
Even though I have made the resolution I figured out to be default, whenever I turn the PC on after shutting down, it goes back to the "green-and-to-the-side" mode. :/ Ain't really a big problem, until I tried to fiddle with the resolution preferences s'more.
Somehow, I have set it to be twice as wide of the maximum my monitor can display, went back to being green tinted for some reason, and is completely shifted left (yet the right side is still visible) This means that I cannot see what is going on the left side, and cannot adjust the resolution preferences, nor can I click blindly cuz the border is only around my visible side of the screen. Now it is stuck like this.
I've researched many hours and eventually found the terminal command for the resolution preferences. it popped up on the visible side. Although it was to no avail cuz I HAVE TRIED EVERY SETTING AND OPTION and absolutely nothing changed. I assume a system restore would simply revert it back to the previous satisfactory settings, but the thing is I want to FIX it. I am new to this terminal stuff, so I want to learn it and all that. To put it simply, here's what I want:
Learn how to manually adjust resolution without depending on a simple dialog box. Make the satisfactory resolution default and consistent through turning it on and off. Link that could teach me the essential commands, all this googling is stressful. D:

My linux workstation recently crashed. After rebooting, Linux (Red Hat 5.3) will not boot properly and automatically went into emergency mode or recovery mode i think. I can still see my /home/user/ and all the files inside.I boot from CD to rescue mode and tried mounting read-only the /dev/sd5 which contains the files in the crashed hard disk to try to copy out my files but mounting was unsuccessful (invalid argument). I checked the filesystem type using fsck -N /dev/sda5 and shows it to ext2. i tried to mount another known working hdd and was successful.
My question is why in emergency mode, the crashed hdd is able to be mounted automatically as read-only but cannot be done in rescue mode thru a bootable CD?Is there any special mount options used in emergency mode?I also cannot copy out in emergency mode booting from the crashed hard disk as everything is read only.

I played with the graphics in kde4 and seem to have losy my installation. i have tried the rescue system option, recover system options and in desperation (i was just about to reinstall) tried booting in failsafe mode, and it worked!
where do i go to find out what the problem is regarding the normal boot mode? i think my pc is starting to resent the continual use of the reset button!

I was reading about ext3 feature and I have read about its journaling modes. I would like to ask what is the default journaling mode of ext3 fs in slackware(or is it in all distro using ext3)? I'll install slackware when my new pc arrive and the fs I will use will be ext3 and I like it to have data=journal mode for its journaling. I have read in some wiki how to set the journaling mode into data=journal mode.
Code: # tune2fs -O has_journal -o journal_data /dev/sdXY Do i need to issue this command or is this the default mode in ext3 in slackware?

I am an emacs user, and I noticed that on my new machine (running F15, 64bit) flyspell-mode will not work in tex mode.
I get errors that look something like this:
Code:
Spell-checking inequality-model.tex using hunspell with default dictionary...
Spell-checking region using hunspell with default dictionary...done
ispell-send-string: Process ispell not running
When done with a buffer, type C-x #

I am getting a pop up window saying: "Not optimum mode. Recommended mode 1280 x 1024 60Hz" In my case, this is happening after installing Debian 504 AMD64, the Samsung "SyncMaster 940N" that gives this message or warning was working fine for a few years on another machine under the previous Lenny distro.
The only way to get rid of this unwanted pop-up window (the monitor is working fine) is to press the "AUTO" switch on the monitor, there is no such option in the menu of the monitor to disable anything or change the resolution and it seems to me that, unlike what was suggested as an answer in similar threads, the problem is not with the monitor but with the distro unable to detect the monitor properly. The only mention in the "xorg.conf" file is as follows and running "dpkg reconfigure ..." has no other effect than creating a new exact duplicate of the file.
Section "Screen"
Identifier"Default Screen"
Monitor"Configured Monitor"

I have an AWL6075 Golden N Wireless Mini USB Adapter from Airlink, and I'm running Ubuntu 9.10. (Kernel 2.6.31-20-generic) I've learned that in order to get this to work, I needed to download this firmware update: http://launchpadlibrarian.net/373876...8192sfw.bin.gz and copy it into /lib/firmware.I have also needed to download and install the drivers at http://www.filestube.com/f76673d157e2ab6203ea/go.htmlI've even Edited my connection to make it available to all users.This is great, and it gets my internet running. Unfortunately, I seem to have to make the module, and insmod the module 8712u.ko everytime I boot up. I know I had it set in 9.04 to be able to do this on boot up, but in 9.04 I didn't have to re-make it everytime.

This AirLink101 AWLL5088 Wireless N 150 Ultra Mini USB Adapter would work on the 11.04 os. Meaning that I can access the internet, because I don't think it has a broadcom driver but realtek one.

All other modes except secondary work fine.
The wireless cards are both PCI, a Netgear WG311v1 and a Linksys WMP54Gv4.1, though I'm not sure which is which.

...to be able to configure the usb modem in my linux computer. As I've been using Linux there onwards, I didn't mind any longer.
Now I plugged the usb into a windows computer but the driver installation routine doesn't start. It's obvious that's because I deactivated the cd mode. How do I bring it back?

I have never had a working suspend. But ... every year or so I try it DOH!!! to see if the updates have solved itI used suspend mode today, and when I woke the system up , all seemed fine untill I tried to browse the internet.It told me I was offline. no ammount of clicking "go online" would work.So, then I noticed the network connection was broken.I did a few things to get connected, and I want you all to tell me what I need to put back again ! IPV4 and IPV6, I unclicked the box to require this for connection to complete.Somewhere else, there was a list of servers to ignore. I removed them all. (I think there werre 3) one was localhost another was similar, and the third was a number.I just want to know what these should be set at, because just because it works - doesn't make it right

After seeing those 4G phone commercials with that newfangled mobile hotspot tech, I have to admit I was eager to trade in my crappy 2 year old CDMA phone for one. That is, until I saw the price tag. 30$ a month for hotspot? No way, so what I did was activate the tethering feature buried deep within the primitive OS accessible only with a plethora of codes and hackery. So long story short: I can now network on the go because Ubuntu sees my device as a "mobile broadband device". Unfortunately, my ipod lacks a USB port for tethering so I use my freed up wireless card to make an AD-HOC network for my ipod to connect through my makeshift modem. Now, my issue is that the modem isn't really that mobile any more because I have to have my laptop OPEN to keep my networks on ,otherwise I close my laptop and no more Adhoc or mobile broadband! So, my question is if I can close my laptop but still keep it connected to the mobile broadband and broadcasting the adhoc network.

I have a HP Pavillion DV7 laptop running Ubuntu 10.04, and I am having some problems with Ubuntu handling a network connection. Every so often, I leave my computer in locked mode overnight to download something. But, when I do this, the network just deactivates early on [there is a symbol of a blank wireless symbol with a red "?" by it]. Both the wireless and wired network connections are deactivated, and I am using a wired connection. This also sometimes happens in suspend mode, too, but less often. I have to restart my computer before it will connect again, as logging out and back in again does not suffice.
