Fedora Networking :: Wireless - Harsh Packet Loss - Cannot Find Any Native AR5008 Drivers For My Card
Nov 2, 2010
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.

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 try to setup a locale network between 10 (Web) Servers (openSuse 11.2), each Server is connected to the internet (eth0) which works fine on all servers.
A 2nd NIC eth1 (1GBit rtl-8169) on each Server is connect to a Switch and should function as a LAN. I installed/configured the 2nd NIC with yast, and than added a route for the local network (192.168.20.0) to use eth1. So far every thing works (ssh for example), but I have a packet loss of 10%-60% (ping) on the local network, and I cant find the reason for the packet loss. I already installed a Debian Lenny on 2 Servers (just to test) but I have the same problem on Debian.
No firewall or any other application is in the way. With tcpdump I could figure out that the packages are send but never show up on the destination server.
I put some more information about how I configured the LAN below. I have not done this my first time and from my experience if something is wrong with the network configuration (wrong routing, firewall in the way, etc.) this usually leads to a packet loss of 100% or the destination is simply not reachable.
The 2nd NIC is installed with either yast on suse , or by editing /etc/network/interfaces on debian. The Kernel module rtl8169 is loaded.
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 UP LOOPBACK RUNNING MTU:16436 Metric:1
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.
Just made the jump to Ubuntu, and until this install I considered myself very tech savvy. Now not so much! Built my new desktop, loaded Ubuntu 64 bit no problem. But I'm having a terrible time figuring out how to load the native driver for my realtek wireless adapter. I successfully un-tarred the file, and used the terminal to run the make command by using cd command to navigate to the file. It returned a wall of text, and in my mind looked to work. Next I go to run "./clean" in the same file location in the terminal and it returns:
"ERROR: Module r8192s_usb does not exist in /proc/modules ERROR: Module ieee80211_rsl does not exist in /proc/modules ERROR: Module ieee80211_crypt_ccmp does not exist in /proc/modules ERROR: Module ieee80211_crypt_tkip does not exist in /proc/modules ERROR: Module ieee80211_crypt_wep does not exist in /proc/modules ERROR: Module ieee80211_crypt does not exist in /proc/modules
Not completely sure if this is an issue, I try moving to the next step of instructions issuing the command "insmod 8712u.ko" in the terminal same file location and get the error message insmod: error inserting '8712u.ko': -1 Operation not permitted I've tried running "sudo insmod 8712u.ko" from both that file directory, and from my home file directory. My guess is I'm missing a step or need to be typing these commands in a different file directory in the terminal.
I am just starting my adventure into Ubuntu. After installing and configuring Shrew Soft in Ubuntu 10.04 64Bit, I am having some serious packet loss issues. The LAN is wireless, however the only packet loss I experience is over the tunnels. I have tried different algorithms, and it seems as I fiddle with the MTU client side, it clears a bit, but the best I have managed is 23% loss average.
I have installed Fedora 14 on my new laptop Thinkpad T410 but the wireless card is not detected. I tried to install the drivers but got error. How to install the driver.
I got a new X201 which is running Ubuntu 10.04. While at home, everything is fine, at work, I encounter some issues with wireless. the signal cuts in and out repeatedly.Here's the output of ping. I set it to ping a server every 90 seconds, 10 times. So this is a snapshot of 15 minutes of network activity...
Code:
PING (REDACTED) bytes of data. 64 bytes from (REDACTED): icmp_seq=1 ttl=252 time=1.50 ms 64 bytes from (REDACTED): icmp_seq=2 ttl=252 time=2.13 ms 64 bytes from (REDACTED): icmp_seq=3 ttl=252 time=1.38 ms

Also I tried this (from a 2 year old thread which was most relevant solution I could find):
Code:
Changing AVAHI_DAEMON_DETECT_LOCAL=1 to AVAHI_DAEMON_DETECT_LOCAL=0 in /etc/default/avahi-daemon has got rid of the irritating pop-up. Basically, every 5 minutes or so, for a solid 60 seconds or so I get no signal. I've tried updating the kernel, and doing apt-get remove avant-daemon, but still have problems.
I have a following configuration: 4 PCs (say, A, B, C and D), running Ubuntu or Debian, interconnected using a gigabit switch, which is connected to the Internet. Two machines (say, A and B) also have a direct private connection between them (provided by another pair of NICs).
Now, when I test the connection performance with iperf, the results vary. The private connection between A and B performs well - about 930Mbps using iperf's UDP test. Between C and D it is about 800Mbps which I find tolerable. Packet loss when running these tests is negligible.
However, when I run iperf between any of {A,B} and {C,D}, the performance significantly drops as there is a huge number of lost packets.
For example, here is the result of testing between A and C:
Why is there such a large number of packets which are generated, but lost somewhere?
A<->B private link works fine, so system level parameters on both A and B are correct. Furthermore, C<->D works ok, so I guess I shouldn't blame the switch.
Is there a per-NIC configuration that I should check or it smells like a hw problem? Problematic NICs on both A and B are of the same type - Allied Telesyn AT2916T.
I have 3 Dell Precision M4400 machines. After getting updates yesterday or today, I get random network dropouts like crazy, on wired or wireless. On one machine I was able to turn off ipv6 in grub and reboot, and it works now. However on the other 2 machines, still have the same problems. All 3 are running 9.10 64 bit. Is there a way I can back out the updates so the network works again? Anyone else see this behavior after updates today?
I'm using kubuntu 9.10 desktop edition as a server and I set the IP statically, what happens is that when I ping it from another machine on the same network, I get intermittent packet loss (up to 80% and sometimes even higher). When I ping any other machine on the local network everything's fine with 0% packet loss. Packets go directly through switch, no router or anything in between.
I suspected wiring issues, but that doesn't seem to be the problem after I changed the wiring. I was connected to wireless and suspected that but no go either. Same thing when I turn wired. I just changed the ethernet card suspecting drivers but that's no good either. Iptables is a cleanslate installation, it's totally empty.
I am running Linux Mint Isadora 9 and recently installed a wireless USB adapter. After installing RT3070 drivers for my RT2070 card I got everything working and life was good. Now, all of the sudden I am having a world of problems connecting to the internet. I can connect to my AP fine, but I cannot access the internet. If I attempt to ping my AP by IP address I get severe packet loss. I cannot ping my AP by url [URL] at all so Im guessing there are some DNS issues as well.

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 been running F13 since it came out, with the wireless working fine since I got it working (using the RPM Fusion repository, broadcom-wl-5.60.48.36-1.fc13). Since I updated software (without reading what was to be updated), yesterday, I am unable to even find wireless networks, although I am, as you can see, able to access through eth0 It is not a hardware problem, as I can not only find them, but access them on Ubuntu 9.10 live disc.

I'm trying to find out what is the difference between wifi0 and ath0 (atheros wifi card) in terms of packet counters shown in proc/net/dev pseudofile. The fact is that wifi0 and ath0 packet counters are different. I've read that wifi0 refers to the physical device and ath0 refers to virtual device over wifi0, so, as far as I know, packets counters in both devices should be the same, isn't it? Another annoying question for me is that ath0 doesn't show any erroneous packets, while wifi0 does.
I am the new user to ns-2. I would like to know is it possible to send the keys or some value as the packet data (content of the packet) in ns-2 (for wireless environment).
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 have installed ndiswrapper, and the correct drivers for the wireless card.
Code: ndiswrapper -l: bcmwl5a : driver installed device (14E4:4320) present I seemed to be having a conflict with the generic drivers which loaded for my wifi device 'b43-pci-bridge' and the ndiswrapper drivers i installed.
So i ran the command 'rmmod ssb' and now my broadcomm wireless device is "unclaimed"
I'm having problems getting the wifi to work on my toshiba satellite pro l40 (psl4be). My laptop has a wifi card built in but linux cant seem to be able to find it. I tryed following these instructions and i got this output:

as you can see its telling me i have no wifi card, even though i am fully aware i do. ive tryed using ndiswrapper to install the windows drivers of the ethernet adaptor but my wifi still doesnt work, im guessing ethernet has nothing to do with wifi.I intend to convert from windows, however if i cant get the wifi to work i can only see linux at a major disadvantage as i use my wifi alot.
I have installed Fedora 8 on my laptop. My laptop has a " Network controller: Broadcom Corporation BCM94311MCG wlan mini-PCI " wireless Card. I want to get the wireless working. I did an 'lsmod' and I found that the modules for this card is not installed. I tried to start Network Manager, but network manager cannot connect to wireless but it cant. How and where can I get the drivers for this and how do I install those modules. My laptop is a Dell vostro 1400.
I am new to fedora linux. I want to know how to install wireless driver for my Dell Wireless Dell Wireless 1397 802.11b/g Half Mini Card. I am using fedora 13. Below is my lspci command outuput.
I believe printers and printing are 2 most retarded things on this planet, completely useless and unnecessary.I haven't had one and never needed one, until now, as in my little retarded country bureaucratic and accounting reasons forced me to buy one, as I have my own company (and I really really hated to do it, but...) Whatever, I got Samsung SCX-4623F (and I will hate myself till end of my life to buy such retarded device), and now I can't seem to figure out how to get it started in Fedora 14. I dont need scanner, just printer. Naturally, there are no native drivers for linux, and I have cups installed and Printing tool in System->Administration doesnt do anything.
My laptop is Gateway M-6335 and I have problems with wireless drivers. I couldn't find any drivers for it. I searched in Software Centre and tried to google it but it didn't work. I have also problems with Bluetooth driver, but it's an other story. I'm using Ubuntu 10.10.
I recently received a used laptop that I was going to use for my kids, a Compaq Presario 2100. Everything went fine on the install, however I could not get the WiFi to work. The internal card, a Broadcom BCM4306, was attempting to use the b43legacy drivers, which I understand to be the native driver for this card, but would get all sorts of strange errors in 'dmesg', and would never get a solid connection.
After fiddling with this for 2 days, and reading countless troubleshooting guides, I finally gave up and decided to get it working with ndiswrapper. Everything worked perfect, except I can only get it to work if I first load b43legacy, then load ndiswrapper, then unload b43legacy. If I blacklist b43legacy, and just load ndiswrapper, iwconfig does not report a wlan0.
I ran across this posting, and decided to try this, but it also did not work. Plus, with this file in place, any attempt to use modprobe would complain about every line of that file.
I have Fedora11 running in my machine and it has no LAN port (RJ-45). I have a wireless PCMCIA card.The model of the wireless card is NL-2511CD EXT2(ETSI).When I insert that card to the PCMCIA slot a window pops up and ask for a WEP key. My wireless router is configured with WPA but above pop-up has no WPA option. I suspect my fedora installation does not have the necessary driver for my wireless card.I want to install that driver. I can transfer that file to the machine via thumb drive since it has no network connection yet. How do I install this? Please refer below images as I'm still a newbie at linux.
