Debian Hardware :: WLAN Fails To Connect And / Or Is Very Slow
Mar 26, 2015
I've tried out many Debian distros and noticed the ones that I try based on Ubuntu, my USB WiFi adapter works fine and I don't really have any issues. When I try one that is based on current Jessie, I have sporadic WiFi issues and just overall instability with regards to connectivity and audio playback. I have tried two distros based on Jessie and had very similar results on both. Is there anything in particular I can try? I've done everything short of installing Debian stable and just pointing to Jessie. I've done that in a VM so I know I can handle it, but wanted to se if there was anything I should be trying first. I just didn't think a distro based directly on Jessie and Jessie backports would be any different from installing base Jessie as far as compatibility is concerned.

i use a telekom s100 set-top-box, which originally had a prism54 wlan-card. but wlan was very slow. but the driver was working well and it did not seem to be a configuration issue, so i assumed that its that card which is so slow. following i purchased a atheros based wlan-card which is working perfectly well with the ath5k driver of my linux kernel (2.6.26-1-686). but the connection is pretty bad anyway. i get max 300kb/s from pc to pc. as its the same with 3 different cards i tested in the s100 i assume it is a configuration issue? or might there be chipset or mini-pci-slot limitation?
when i check the connection with iwconfig the bitrate is somewhere between 1-54mb/s, rising to 54mb/s and then falls back to 1mb/s, rising to 54mb/s again, falling down, its an infinite loop. im using wpa_supplicant for the connection, but i don't think thats the malefactor. well, you never know .. i tried to set the bitrate with iwconfig wlan0 rate 54M but that ended in a disconnection ...

I've tried both the EeePC installer and installing squeeze and neither could work my wlan or ethernet. I'm currently running Ubuntu Netbook Remix, but I really want to stick with debian.

Since a recent update on Stretch, I have been unable to use the network-manager to connect to my home wireless network on my laptop. It was working fine before. I did not change any settings on the WLAN router. I can still connect to other wireless networks at work and university, just not this particular one at home. All other non-Debian devices in my household are still able to connect just fine.While figuring this out, I have tried connecting manualy with ifup but I don't really know how that works. Right now there is only the loopback entry in /etc/network/interfaces.
Below is the output of syslog, when gnomes network-manager is trying to connect, but fails.
Code: Select allJul 19 20:01:57 debian NetworkManager[6705]: <info> (wlan0): Activation: starting connection 'Affenbande'

I installed Fedara 15 yesterday. I was running Fedora 13 before. Since I did the fresh install, my wireless network runs really really slow, i.e. a few KBs every 30 seconds whereas it ran at full speed in F13. I couldn't find the reason for it. I now tried the live-CD for Fedora 14 and it runs at full speed out of the box (whereas F15 is slow even with all updates installed).
Does somebody know a solution?
Laptop: Lenovo X201
Network Card: Ultimate-N 6300
I gathered uname, iwconfig, lspci and dmesg output for both, Fedara 15 and Fedora 14. But as the number of links is limited here in the forum they're all linked here: [URL]

I'm running squeeze/testing. Two or three days ago I became unable to get my mail from pop.gmx.net. A bit of investigation and I found that the error message I was getting was: "could not resolve pop.gmx.net: Name or service not known". Now the funny thing is that I can ping, traceroute, or nslookup the site successfully. Telnet, rlogin and ssh give the same: "could not resolve pop.gmx.net: Name or service not known" error message.
I have tried using the IP address instead of the pop.gmx.net and everything works fine. There is no issue with connecting to pop.gmail.com on the same port. Obviously there is some cache somewhere with a messed up pop.gmx.net. Any idea as to how I can track this down?

I have set at static ip on eth0:
In have configured the /etc/network/interfaces as:
Code:
auto lo
iface lo inet loopback
auto eth0
[Code]....
However, I experience a slow Internet connection when using wlan.
Is this a routing issue, or have I configured the /etc/network/interfaces config file wrong?
I use Ubuntu 10.04, 2.6.32-22-generic

I finally have my system to where I can connect to proftpd but my uploads fail. I think my problem lies in the upload folder. I do not really understand where to put it. Will someone look at this config file and tell me where to put it and what I need to do to get it working. A basic anonymous configuration, no upload directories.

After updating to kubuntu 11.04 natty, I have a problem with my internet-connection. The problem happens when I use VoIP-Software like Skype or Twinkle and also when using ktorrent.
When using the mentioned software, after 30-90 seconds the internet gets very slow. In f.e. skype, I can hear the one I phoned very badly.
I use kubuntu on a desktop-PC with a Linksys USB-Wlan-Stick. Detailed information is below.
Code:
uname -a
Linux pr1-desktop 2.6.38-8-generic #42-Ubuntu SMP Mon Apr 11 03:31:24 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux

I just installed ubuntu as my primary OS, but I have the disk with XP on it and I don't want to go back, but I need faster network connectivity. I have a T60p with Intel Gigabit jacked into my Gigabit router which also has my desktop (running XP) and my NAS. If I FTP files from my NAS (or SCP), I get transfer speeds around 250-500 KB/s (which is not very fast). On this same switch, from my XP desktop I get transfer speeds around 12 MB/s. I get the same speeds using my 802.11n card (Atheros) as with the ethernet NIC (250-500 KB/s).The drivers for the ethernet card and the atheros card are e1000e and ath9k respectively.I have disabled IPv6. Since the problem occurs using either interface, I am just going to concentrate on fixing it for the Ethernet interface (since I believe it to be a systemwide problem).
Code:
skinnersbane@albert:~$ sudo ethtool eth0
Settings for eth0:
Supported ports: [ TP ]
Supported link modes: 10baseT/Half 10baseT/Full
[code]....
Clearly my card is running at Gigabit, but why the bad transfer speeds? I am using filezilla for FTP (technically FTPES). I closed every other program. My CPU utilization does seem high and I wonder if this is part of the problem. I had no problems with throughput using either interface in Windows XP just one week ago.

I've decided to try out Ubuntu again on my Samsung netbook. I tried 9.10 before and a lot of things didn't work so I gave up, but that was quite a long time ago and I wanted to see if the new one will work.
I booted 10.10 off the USB stick, don't want to zap my Windows 7 installation if Ubuntu doesn't work. Everything seems to run fine, the webcam works, wireless seems to work, it shows the networks in the range and allows me to pick the one I want to connect to.
Sounds good so far, but when I try to connect to my WLAN and put in my password it thinks about it for a while and just pops the password again. It can't seem to connect to the network even though it sees it and the password is correct. I triple checked the password, it's definitely correct.
I can only assume there's something wrong with ubuntu and the driver. I have a Samsung N140 netbook which uses Realtek 8192E chipset.

Linux is what i'd like to learn, so Howdy to all and i hope to speak to you all regularly
in short, I started with Ubuntu Linux about 6 months ago, Didn't like it, i researched various distro's and came across, PC Linux OS, it was really cool, But i couldn't get it to connect Wirelessly, so i tried something else... the bottom line is i finally settled on SUSE Linux Enterprise Desktop 11, i seem to like it a lot.Ok.. now that introductions are out of the way
Background info: I've installed SUSE Linux Enterprise Desktop 11 on my Sony Vaio Laptop (VGN-NW15G) with no major issues, after a bit of mucking around, i got the LAN to Connect to the internet, after some more mucking around, i figured out how to get the WLAN to connect to the internet.MY Goal: To be able to Wirelessly Network my Laptop with My PC.so that i can access the files on the PC, From my laptop, and Vice Versa, but the important thing is to first be able to access the PC files from the Laptop.
NOTE: My PC has 4 Hard Drives (1 for the O/s, 3 Backups) they are all configured and Shared correctly for Networking and Wireless networking, and all the permissions are set correctly.Hardware and Software Environments:My Laptop : Sony Vaio VGN-NW15GOperating System : SUSE Linux Enterprise Desktop 11Wireless Capable, and has no issues Wireless Networking when running of a Hard Drive Loaded with Win 7 Ultimate 32bit, Therefore all Hardware is Compatible

I am trying to connect to a WEP encrypted WLAN without using the DHCP server of the AP. (=giving myself a static IP)
So far i have tried:
Code:
But i cant even ping 192.168.1.1 (Network unreachable error). Is it possible that Ubuntu tries to use eth0 (which was connected to a similar /16 before) to ping 192.168.1.1 or is there somethign wrong with my commands?
Also will an AP allow access to the network although i don't have an IP from its DHCP server?

I have a RedHat linux server box connected to LinkSys router through ethernet port. I've assigned a static IP to the Linux box, which is out of range with router's DHCP range.
The Linux box has Apache, JBOSS, SVN and several other services installed, but none of these services are accessible through the WLAN. However, SSH and SFTP are accessible from WLAN.
Another interesting observation is that if I open a browser on the linux box (by exporting the DISPLAY to Exceed on my laptop on the WLAN) and point the browser's address bar to localhost:80 or localhost:9080, then I can access these services!!.. So, I suspect that something is wrong with accessing these services from a client on WLAN and I am looking for a solution for the same.

Since I have installed Fedora 13 it seems that I can't connect to WLAN APs which aren't secured by WPA. I'm surprised about the inserts to the messages logfile:
[Code]...
Most surprising insert for me: Jul 5 20:43:21 nbtobiaslnx NetworkManager[1328]: <info> Config: added 'key_mgmt' value 'WPA-PSK' Is this the reason for my problem? I use KDE and Network Manager for managing my networkconnections.

Under OpenSuse 11.2 i cannot connect to my wireless network. Sometimes computer doesn't see network, sometimes computer cannot connect to it. Encryption: WPA & WPA2 Personal Kernel driver: ath5k Also I am embarrassed that in lspci and yast written various models of my wifi adapter.

I have installed opensuse 11.2 on a second partition, with the ultimate aim of leaving windows altogether. Unfortunately, I seem to be having terrible trouble (as do many others) getting my wireless internet connection working. I have viewed lots of posts in these forums and done everything I can think of, but since I am a linux novice, am unable to identify the problem. The card is working, since it can identify local SSIDs, it has been set up (to the best of my knowledge) correctly in YAST, but nothing seems to work.
I'll include some information I have recorded from my system.. I typed the commands below with the accompanying output listed:

I have a problem on Ubuntu 11.04 64-bit. The wlan does not connect automatically on reboot, although "Connect automatically" is ticked in network manager. I always have to choose "Connect to hidden wlan", choose my config, enter my password, then connect. Once connected everything works fine. But it's kind of annoying to manually connect each time after a restart.
- hidden SSID from router
- mode -> infrastructure
- connect automatically -> ticked
- available to all users -> ticked
- Encryption -> WPA & WPA2 personal

I'd like to go one step further now, with my laptop. As I'll be travelling more often in the foreseeable future, I'd like to be able to connect to WLAN hot spots in hotels, railway stations and air ports with a minimum of hassle. What's the best way to go about it?
Of course, Wicd is quite useful, but I'd prefer a KDE application, and I'd like to be able to define "profiles" for various scenarios. Certainly I am not the first Slackware user with this requiremnent, and probably there are tons or docs regarding this topic. However, searching LQ and the internet I haven't found what I am looking for.

recently I risked a look to the Linux world and I'm happy so far, but now I've got a Problem, I'm unable to solve by myself. I installed Mint (Julia) on my old Laptop to test Linux. The Laptop has a very old PCMCIA WLAN Card with a Realtek rtl8180 chipset. Everything seems to run perfectly so far with one exception: the WLAN doesn't find any Network to connect although the card and the driver seem to be installed correctly.
Here some code from the terminal:

I upgraded Ubuntu to 11.04 I can NO longer connect wirelessly using my BCM4312 WLAN Card. It connected with no problems before dist upgrade using Ubuntu 10.04. Im really not sure why I cannot connect. I cannot even see my router in edit wireless connections settings. I can however see my neighbours routers who are using WPA2 encryption. But I cannot see my router.
I have uninstalled and reinstalled The Broadcom STA proprietry wireless driver several times using Additional drivers. This did not fix my issue.
I am connected by ethernet at the moment so I do have internet connection.

I have a ThinkPad x100e with a wireless card.Code:03:00.0 Network controller: Realtek Semiconductor Co., Ltd. Device 8172 (rev 10)my problem is that I can't connect to my wireless network with Gentoo. I've been running Slackware64-13.1 on this computer and now have Windows 7, Ubuntu and Gentoo installed. Slackware, Ubuntu as well as Windows 7 connect to the wlan without problems. I'm using the driver rtl8192se, the module is loaded r8192se_pci and is the same with Slackware and Ubuntu.
I've read many posts and found that other people experience problems with Realtek wlandevices as well. But I have no Idea how to get connected with Gentoo at my wlan. It looks like that the netbook is connected for a very short time, but when dhcpcd broadcasts for a lease the connection is already closed.

There is no wlan0 interface when trying to run FRITZ!WLAN USB Stick N 2.4 on OpenSuSE 11.2, though it works fine on Fedora 11 and Mandriva Spring 2009.1. All 64bit. Contrary to Fedora and Mandriva, there is no need to compile the compat-wireless module ar9170usb for OpenSuSE 11.2 because the kernel is very recent and includes this driver. Kernel: 2.6.31.5-0.1-desktop The /var/log/messages gives this after I put the stick in the PC. At first it is seen as a mass storage device:

so far i testet 4 wlan cards (prism, ?zytel?, realtek and another realtek) they all work without a problem with kubuntu. but with ubuntu they dont want to build up a connection to my router. it looks like the passphrase is wrong..he asks me after a short time to reenter the phrase. but the phrase isnt wrong(copy pasted) the phrase has some special characters but only '=' and a few '!'. so i doubt that that could be the problem im pretty sure there are more people out there who have the same problem. I hope someone knows a solution :/
edit: i did some searching and found this... seems to be a major problem[URL]...
