Fedora Networking :: Wireless Much Slower In FC12/13 Than In Windows
Jun 11, 2010
"Dell 1525 WLAN PCIe card with11n mini-Card & external antenna" wireless card. It got recognized fine by FC12, but it was rather slow. I had read that life would be better in FC13 with the new kernel. After a long wait, I upgraded to FC13 yesterday.
It seems that the wireless is indeed faster. However, it it clearly a lot slower than under Windows 7 (it is a dual boot PC). My test is simply to play say Hulu in full screen: under Windows it looks fine, under FC13 it plays in slow motion.
I've been using fedora on my Lenovo R61i since I got it...I believe the first version I used on this laptop was f10. I always try to keep it on the latest distro and I also enjoy a clean install every year or so. One thing I was always impressed with was how quickly I could go from sleep to back up and online. So I decided it was time for a clean install this weekend to fedora 15. Now when I wake it up (open the lid), it takes over a minute for the wifi to connect again. This hasn't been the case for the last 4 distro's so I'm wondering what I can do to speed that process back up, is there a particular package I can downgrade or is this something on their radar already and I should just wait for an upgrade?
I recently switched my mom from Windows to Fedora , and ever since her Internet speed went down. Now it takes, on average, 6-8 seconds longer for her to load a web page with Firefox. Tried to replace the modem -- didn't help. She is on a DSL connection.
But here is the striking part. Her BitTorrent speeds are better than mine, and I have a cable rather than DSL.
I can't for life imagine how these two can coexist. An innocent web page takes forever to load, and torrents are so fast. By the way, she does say that torrents used to be *even* faster on Windows.
I'm having problems getting two wlan cards to work under Networkmanager with F12. I have an old server that I wanted to move, so thought I'd get a USB wlan device for it. before setting up the server, I thought I'd try the USB (an Edimax EW-7711USn - Ralink 2870) on my laptop first. My laptop has an inbuilt ipw2200 card that works fine under NM.
So I've down loaded the DPO_RT3370_LinuxSTA_V126.96.36.199_20100831.tgz file from Ralink, and built the driver (after changing the os/linux/config.mk file for the WPA supplicant settings). I also install the rt2870 firmware (from Ralink) in the /lib/firmware directory. I also blacklisted the rt2800usb driver to ensure that that didn't get loaded.
The problem I have is that I can now get both the ipw2200 device and the rt2870 devices 'working', but they both try to assume the same IP (I want fixed IP's and not DHCP for them) - what is the way to configure the 'devices' so that the rt2870 device is always given IP x and the ipw2200 given IP y?
I think my problem is really my lack of understanding where/how NM handles the files under the GUI config. I used to semi understand how the old network config tool set up it's files and where they were etc. But with NM I'm a bit lost as to how it equates the device with the network settings. Once I have the device working with the correct driver on my laptop, I'll look to apply the same settings on the server (which is then FC13 - but should be simpler as it doesn't have an existing wlan interface).
For some reason on these days i've noticed that my internet speed seems to go faster when i'm on my windows partition (shame on me i know xD) when i go back to my linux pages take too much time to load, which doesn't happen in windows, i have never had this problem before/
My school has (once again) chosen to change their wireless network. This means it has gotten a lot slower, and that only our hotspot works. Our hotspot however is secured so that im unable to enter facebook, and a lot of other websites, etc. So what i did in windows was installing a program called hotspot shield, which redirects you ip through a server, so the LAN Admin basically have no control of what you're doing if he haven't got more skill than the one we have. I think what Hotspot shield does is making a vpn connection (correct me if im wrong) and i would certainly like to do that i ubuntu as well.
Since I use my computer for some intense processor calculations, without any fancy graphical needs, I decided to apply a mild OC on the BIOS settings, to speed thing a bit up.I own an AMD Phenom II 1055T (2.8GHz) cpu. I changed the base freq from 200 to 203, and changed the multipliers of the standard and boost freqs to x15 and x16.5, so now the BIOS reads 3045 MHz and 3349 MHz for both speeds.
The same network environment, no matter which browser I use, my fedora 13 always works slower than windows XP on loading web pages. Others are better than windows -- like memory management...(I directly feel that). applications running more smoothly than those in windows xp.
I want to know how could I make it faster on loading web pages.
I recently upgraded my CPU (just before the release of FC12), to a 64-bit compatible Intel Core 2 E7600. Upon the release of FC12 I moved to the 64 bit version (via a clean install).
I noticed that NVIDIA does not work (as many topics on this forum confirm). So I reinstalled and used the FC12 default drivers (I think they are called Nouveau-drivers). This seemed to work, so I ran "yum update", and now all X-windows fail.
KDE complaints: "kstartup4 does not exist or fails" and GNOME also complains (sorry forgot the exact error message)
I'd be happy to send logs, but if these are required, which log you want and where I can find it.
how to get or KDE or GNOME running ? (preferably KDE)
Is it possible to have fedora 12 join a specific wireless network (my home network) before i login to the gnome enviroment on a standard install? i would like to be able to hit the machine via ssh without needing to be logged in.
My current task is to add windows 7 to fc12. From other postings it seems the next step is to use the fc12 install disk to create a windows partition from the unused space. Could someone inform me about whether this will delete my current installation of fc12 and my home directory.
The relevant details of my setup are: Samsung R522 laptop Realtek RTL8192E wireless network controller (PCI) Fedora 12, kernel 188.8.131.52-70.fc12.i686 (automatically updated using software update)
My problem is that my wireless card has never worked - basically there aren't any widely available linux drivers, and there are many threads on getting the RTL8192E to work on many different forums, e.g. here, but none specifically for Fedora, so I think that this thread could potentially guide many more users. FYI, my hardwired network connection works perfectly.
Fantastically however, by emailing Realtek support, they'll send you their Linux driver, which most people have claimed works perfectly (although why they haven't just put it on their website is beyond me). SO, I've got a Linux driver for my wireless card. When Realtek emailed me to send me the driver, they said to just 'cd' into the driver directory, then do
su make clean make make install reboot ./wlan0up or ./wlan1up
OK, so I tried to do this and get the following error: make: *** /lib/modules/184.108.40.206-70.fc12.i686/build: No such file or directory. Stop. make: *** [all] Error 2
I don't know enough about linux to understand this error. I really don't want to have to recompile my kernel, and I hope there is some way to install this driver with not too much hassle. How to overcome this error, and install my wireless driver so I can get wireless network access on my Fedora 12 operating system. I've found Fedora 12 really easy to use so far, but this is proving quite hard!
This is the output of 'ls -lh' in the folder which seems to be causing the error, namely /lib/modules/220.127.116.11-70.fc12.i686/ total 3.1M lrwxrwxrwx 1 root root 46 2010-03-16 22:53 build -> ../../../usr/src/kernels/18.104.22.168-70.fc12.i686 drwxr-xr-x 2 root root 4.0K 2010-03-03 05:28 extra drwxr-xr-x 11 root root 4.0K 2010-03-16 22:53 kernel -rw-r--r-- 1 root root 498K 2010-03-16 22:53 modules.alias .....
I have a FC13 box that has both Gnome and KDE sessions installed.
I have noticed on the KDE session that data transfer rates are slower than when I use Gnome.
In Gnome, I can transfer files between my FC13 machine and my Ubuntu 10.04 pc at a rate of 6.5 MB/s (52 Mb/s if my maths is correct), but in KDE the rate is only 3.5 MB/s (28 Mb/s).
"ethtool eth0" shows my NIC speed as 100 Mb/s. Obviously I am not hitting anywhere near that speed in either session, (a separate article may be happen in the future to address that), but I am curious as to why KDE is that much slower for file transfer.
I've been experiencing a problem with Fedora in which when I enable Wireless in Fedora, Wireless networking does not work in windows. HOwever, when disabled, it works correctly. Windows claims it is "not able to find any networks to connect to"
EDIT: It seems that when wireless is disabled manually on fedora before shutdown, there are no problems in windows.
I installed Fedora Core 12 on a Dell Latitude 610 laptop. Networking isn't working. I tried to start networking with '/etc/rc.d/init.d network start': there were no errors or warning messages, but before and afterwards, I could not ping anything.
I tried to configure and start networking with system-config-network. The ethernet network card shows up, but the activate button is greyed out.
I can ping the loopback address 127.0.0.1 after I start networking with '/etc/rc.d/init.d network start' but I don't really know what that means.
lspci tells me that my network "card" is a "NexXtreme BCM5751 Gigabit Ethernet PCI Express".
I know the eternt cable is good because I used it on another machine.
I been a windows guy forever, and wanted to make the switch. Anyways, I am hoping to do a wireless wake-on-lan from a windows box. I have an older laptop that has a dead screen and I am trying to use it as a server. So, I want to be able to VNC the linux box from my vista machine. I think that's going to be straight forward. But, the linux machine doesn't have a builtin wireless card, so I am using a USB wireless deal. If I let the laptop hibernate/sleep after being idle, can I wake from my vista box over my network?
I have a tricky problem which I could soIve with a c program. I wrote one and found I didnt have gcc so I tried to install it. I was told I needed to install packages. I acknowledged and an error was generated gcc-4.4.2-7.fc12.i686 requires libgomp = 4.4.2-7.fc12 I try to install libgomp and go round again.
I have just upgraded to FC 12 from FC 11 everything on FC 11 was fine, I has samba, openvpn, subversion, tinyproxy and apache all working fine. Friends could vpn in and do all the stuff they where allowed to do,
Now unfortunately I have this issue after upgrading to FC12, All the samba mounts have disappeared from all my friends computers, when I look at the log files I now see this;
smbd/server.c:457(smbd_open_one_socket) smbd_open_once_socket: open_socket_in: Address already in use
/sbin/lspci reports this: 01:00.0 Network controller: RaLink RT2800 802.11n PCI iwconfig reports nothing Network manager doesn't see it. The card works when I run it from Win 7. I tried rt2800 and rt2860. no results I am fairly new to Linux and I don't know all of the command line functions, How to get my wireless PCI card detected. After I installed the rt2860 driver, I didn't reboot. After rebooting, the card lit up and now I am functional. Woo Hoo.
It used to have a lightening speed. But now every application is taking few seconds to start, even on Konsole, the commands take some seconds to get typed ! (I literally have to wait for cursor to move and commands to get typed on Konsole). Folders are taking some seconds to get opened !
I rebooted the computer but that proved to be useless.
Here the ps output:

I've installed Ubuntu Maverick on a testing machine, a Samsung N510 (Atom N280/2 GB RAM), and I've been quite surprised that I haven't been able, due to slowness, to reproduce MPEG2/DIVX videos (using VLC).When I subsequently installed Windows XP, the videos were playing fluidly.Now, I also noticed, although this may potentially be biased, that the overall responsiveness of the system is a bit slower than when I use Windows XP (drawing speed of objects).I remember having the same feeling I switched (years ago) entirely from Windows to Ubuntu.
Why is video decoding so much slower on Ubuntu?Providing that the second point (desktop system speed) is not biased, is gnome inherently slower than Windows XP's GUI? Why, if so?
I'm posting this here because I have no idea how to address this issue. I have an Ubuntu 11.04 with Windows XP on VirtualBox, Firefox 5 on both machines (virtual and real).I thought my connection was slow when I realized that the browser in VB was much faster than the one in Ubuntu.The problem doesn't seem to be on firefox because Chrome also is slow (I haven't checked Chrome in XP-VB).When I type an address in Firefox Ubuntu it takes a long time to show the page and sometimes the whole browser gets stuck for somewhere around a minute.
kernel-22.214.171.124-90.fc12 seems to break 802.11n with my intel 4965 chip on my thinkpad t61p. Anyone else seeing the same thing? iwconfig shows extremely low bit rate. dmesg doesn't show anything at all unusual.
I have a big archive with about 10000 documents in a usb stick. What I have noticed is that browsing of that archive with gnome is much slower with ubuntu than winXP ( dual boot , same PC ) where it is almost instant.I have disabled assistive technologies and installed Thunar file browser. It improved things but again the lag is important. Linux is in general much faster than windows, so I wonder why is it happening ?
The system will also crash when booting if it is not plugged in. However, this behaviour is not consistent. The crash is not really a crash so much as a complete system freeze, where not even the numlock light on the keyboard will turn on or off. I have to do a hard reset to get it going again.The last entry before the reboot in /var/log/messeges just shows eth0 link going down.
I'm using openSUSE 11.2 64bit in Dell E6400 with Intel video chipset. I can play x264 720p files without any problems in Windows 7, but in openSUSE, I could play it in Totem, but it is very slow (lots of stopping).
In addition, in songbird, if I use the mediaflow add-on,the scroll becomes really sluggish.
In general, I feel like openSUSE is showing less ram usage but higher CPU usage than Windows 7. Is my video card driver is messed up? I really like openSUSE a lot but so it is disappointing....
I have a 2-year old DELL XPS M1330. I used to have Windows Vista on it, but over time, I believe it became clogged with too many programs and so I wiped the hard drive and installed ubuntu 10.04 LTS about 2 weeks ago. However, ubuntu many times seems to run slower than vista did. I have 4 GB of RAM, an Intel Core 2 Duo T8100 (2.1 GHz, 3MB Cache, 800MHz FSB), 320GB HDD, 128MB nVIDIA GeForce 8400M. Ubuntu recognizes me as having dual processors at 2.1 GHz and 3.4GB RAM, but when I'm watching a simple video, whether online or locally on the computer, my CPU usage invariably jumps to 100% and it lags. Sometimes, even simple word processing makes it slow significantly.
Debian lenny, old install (I've upgraded to lenny when it was just about to become the stable release), versus windows 7, fresh install.Comparing browsers speeds with numion.com/Stopwatch.html, I had results such as:Iceweasel (firefox) on linux: from 9.154 seconds to 21:860 seconds (the same webpage, reloaded)Firefox on windows: 4.32 seconds - and never much slower than thatThe fastest browser on linux was Opera, ranging from 8.562 to 5.503 secs to load the same page, but even internet explorer beat/match it with its timing of about five seconds.
I have not other browsers on windows; on linux there is aroraonqueror (KDE3), kazehakase, chrome, and dillo, besides text browsers. I didn't test on dillo; Kazehakase and chrome were the only ones which had nearly decent results, but still very bad, 11 to 13 seconds for chrome, and 21 for kazehakase. Konqueror just seemed to never finish to load the page, I gave up when it was still loading somethingfter nutes and 5 seconds.'ve emptied the cache every time I would test, and I was running almost only the browsers and not much else. Whatever comes by default on windows, and on linux, I was on openbox, with nothing much going on I guess, I think the most memory consuming processthe time, besides xorg and the browsers themselves, was dictd.
I've researched a little bit about, but not enough to make a list of possible things to change in order to improve the speed on linux. Most of the time there are people just agreeing that on windows the rendering is faster, and other people saying that with them is the opposite, with some minor variations like people saying that linux is faster for plain downloads while windows is faster for web browsing due to better graphics.
(by the way; I haven't installed any graphic card driver on windows, which is still running on 1024x768, while linux runs on 1280x1024, with the "nv" generic driver, without fancy options, not supported by my old card) The closest to a suggestion of possible solutions was someone saying tha compilation may affect performance, I guess it was both about kernel compilation, and the web browsers themselves.I'll google a bit more about how to "compile for speed", both kernels and programs (maybe the x server
When I copy files to my External NTFS HDD using Ubuntu the write speeds are about 10-12 MB/sec, but when I copy files using Windows the write speeds are about 25-30 MB/sec.
Exact same files, tried all three ports on my netbook and even timed it to see if the speeds are by any chance miscalculated by either operating system and Ubuntu is definitely writing at half the speed.
So what could be the problem? When I had Windows on this Netbook I never got had a problem with write speeds so I don't think it is a hardware issue.
Im experiencing a strange problem with 10.04. When it first boots up its reasonably quick (as snappy as Gnome ever has been) but after its been running for a day or two it gets ununsably slow and has to be rebooted.
I dont see how it can be anything to do with my hardware as it runs OK when first started. Ive monitored RAM usage and it doesnt seem to differ much. There's always the same amount unused.
