Debian Hardware :: Realtek RTL8192SU Stops Working Under Load

Mar 14, 2015

Have a very unusual problem that I am looking at troubleshooting. Only problem is I don't know where to start.I have the following wireless usb device:

Code: Select allBus 002 Device 007: ID 050d:845a Belkin Components F7D2101 802.11n Surf & Share Wireless Adapter v1000 [Realtek RTL8192SU]

Now it is fine when browsing the web, but whenever I download a large file/game from Steam it becomes unresponsive and stops working.I have noticed it happens whenever the download is maxed..which at the moment is at around 5.4mbps on steam.Never get a warning...just internet stops working...no pages can be displayed...The connection never disconnects.I can only get it working again when I unplug it and re insert it back in again.

Things I have tried:
- Returning it to the shop and getting a new one (didn't fix it).

Code: Select allzerocool@hal9000:~$ uname -a
Linux hal9000 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt4-3 (2015-02-03) x86_64 GNU/Linux

Ubuntu :: Network Manager Stops Working Under Heavy Load?

Jan 19, 2011

this is with both network manager and WICD, a problem i've had since i got ubuntu - multiple wipes and reinstalls the wifi is supported out of the box, the problem i've randomly run into since installing is, it will randomly stop detecting networks "no networks detected"

i've noticed over time as this as been happening, that it usually happens whenever there is a high load - multiple videos going on multiple tabs, videos queued up etc. its never happened during regular browsing - theres always a lot going on when it happens, almost like it collapses. the only way to fix this, is to quit the manager - shut off the computer (restarting doesnt work) and then it comes back after

Debian Installation :: How To Force Load Realtek-firmware Driver During Install

Dec 25, 2015

Now, my issue is that I have no access to ethernet in my apartment so I need to rely on wifi for my install. But during the install when it is looking for the network hardware it never sees the TP-Link Dongle and never asks if I wan to load the firmware. I even tried it with the CD image that has the non-free drivers included but it never asks for the drivers. Any other distro, like Linux Mint 7.3, sees the dongle fine.

So is there a way to force load the realtek-firmware drivers during install?

Ubuntu Networking :: Stops Working In 10.10 And Firefox Randomly Stops Working?

Nov 13, 2010

I'm running Ubuntu 10.10 Maverick Meerkat 64-bit on my desktop with a wired internet connection (with no firewall). For the past 2 days, I have observed that1. Firefox randomly throws up errors like "Problem loading page" whenever I click on a hyperlink. When I click on Reload, the page loads up just fine. This has been happening a lot recently..and I do not remember updating anything consciously. By the way, ipv6 is disabled in Firefox.2. The network stops working all of a sudden (usually indicated by the Firefox error). The Autho Eth0 indication is active, but I am unable to connect to any external machine.

3. Needless to say, this error is manifesting itself in apt-get as well. I get "something wicked happened" errors all the time, and am unable to download or install anything.That this is not a problem with the ISP is obvious because I also have Windows (from which I'm typing this, ironically), which is able to access the internet.Is this a bug in Ubuntu 10.10?

Debian :: NIC Stops Working Every Now And Then?

Jul 18, 2011

I use my debian machine for masquerading, packet filtering anilar for a tiny network.It runs the latest debian testing.Every now and then (i am talking about weeks) the connection to my internet stops working.ifdown eth0; ifup eth0 brings it back.The other interface (eth1) is never effected.The odd thing is, there are no warnings, no messages .. nothing.I cant find any entry. Nothing in the logs, nothing in dmsg and no kernel panic.The only way to find out when it might have been happened is to search in several daemons log files,to find out when their first error connecting to the internet occurred.I ran memtest without any results.The nic is e1000 compatible.

Debian :: DNS Resolution Stops Working Sporadically

Jan 31, 2016

I have a Lenovo Thinkpad R500, and recently I recently upgraded it with a Crucial SSD as well as 8 GB of DDR3, as I had a blank SSD installed, I decided to switch from Mint to Debian and see how I like it. I'm using Debian 8 with the MATE desktop and so far it's been quite a pleasure to use, besides one small thing.

Every 5 to 10 minutes, DNS resolution stops working completely. I can ping IP addresses as well as connect to websites by IP address just fine, however I cannot resolve hostnames. The problem exists regardless of whether I'm connected to my router via a wired or wireless connection. It is not occurring on any other computer in my house and didn't exist on my old Mint installation. If I disconnect from my home network by either unplugging the Ethernet cable or flicking the WIFI switch on my laptop, and then reconnecting, I can resolve hostnames again, albeit only for another 5-10 minutes, when DNS stops working again.

I was originally using DHCP and my ISP's DNS servers, but switched to my laptop using a static IP address and Google's DNS Servers at 8.8.8.8 and 8.8.4.4, the problem persisted after this change.

Debian :: 8.0 - Icons Disappear And Terminal Stops Working

May 16, 2015

I am having a problem which I am having a hard time finding out about. To start I am running Debian 8.0 on a laptop through an external Seagate 2TB HDD that I connect via USB 3.0. My problem, basically, is when ever I use Linux for an extended period, for what ever reason, some of my icons disappear and my terminal breaks. More specifically, say I were to try to shut down the computer at the time of the problem the icons and text telling me which option is which, in xfce4, are gone. Then if I click on the would be shut down button it just goes to a black screen with a white underscore and hangs there. This symptom is probably due to the fact that commands in the linux terminal stop working. As in, if I were to type ls it tells me there is no command (something like that) and tells me some folder directory that I think is where bash is located. I wish I could be more specific with some of these details.

Anyway the only way for me to "fix" it is to just do a hard shut down, then upon reboot it clears the orphaned nodes. Also, before, when I installed linux several weeks before I never noticed this issue, if it was ever present. However, now that I have seen it, I have since tried re-installs of debian to no avail. I have a feeling it could be the external hard drive, but that notion is not based on any evidence.

Debian Configuration :: Web Site Stops Working / Have To Reset Networking

I'm running Debian server 5.0.6 and the latest stable version of Apache. I am hosting a website and it will stop responding after an unknown amount of time. In order to make the website work again I have to run /etc/init.d/networking restart. The server is running a static IP address and is not resetting when the website goes down. I don't know where to start looking.

Debian Configuration :: Wireless Stops Working After Kernel Upgrade?

Aug 17, 2011

Testing distribution. Installed Linux 3.0 but left 2.6.32 on as backup. When I boot into the old kernel, wireless mostly works OK, but never when I boot with the new kernel.

Results of dmesg|grep wlan0 on 2.6:

[ 22.005102] ADDRCONF(NETDEV_UP): wlan0: link is not ready
[ 28.196774] ADDRCONF(NETDEV_UP): wlan0: link is not ready
[ 28.644779] ADDRCONF(NETDEV_UP): wlan0: link is not ready
[ 30.688053] wlan0: direct probe to AP 00:19:5b:06:9f:ba (try 1)
[ 30.694053] wlan0: direct probe responded

[Code]...

Noticing the Access Point looked like it needed the MAC address, I ran iwconfig wlan0 ap <MACADDRESS> and sometimes it will work, and wicd can connect to the access point. But sometimes the command fails to run.

Ubuntu Networking :: 10.04 RTL8192SU Driver Causing Boot /freeze Ups?

Jul 10, 2010

So I have recently been making attempts at setting up my RTL8192SU chipset usb wifi. After struggling to set it up by following the steps on this link: [URL]../url?sa=t&jUyXQukrfIw After doing this I had no idea what it was supposed to look like but It did display several warnings along the lines of "warning: cast from pointer to integer of different size" I continued following steps as another error occurred "cp cannot stat autoconf.rtl8712_usb_linux.h" I then entered sudo modprobe 8712u and my screen went black i was forced shut down . Upon rebooting I found it also would lock up if my usb device was plugged in It will boot with it unplugged but as soon as it is plugged in again it will lock up my system and send it to a black screen.

Fedora :: How To Get Realtek USB Wireless Working

Oct 22, 2010

Supported chipsets:
8188
8191

Terry Polzin on the Fedora list today posted a request for help with getting a Realtek 8188S(U) working. I replied saying that I had a similar device and shared my experiences.

I told him that there is a driver in staging which supports the device, but that Fedora only ships quality working drivers by default, so no staging drivers are included. It's easy enough to get them though, just add the RPMFusion Free repository and install their kmod-staging package which (as the name might give away) includes the staging drivers for the current kernel.

Once you have that installed, the r8192s_usb module can be loaded, but the device still needs external (presumably proprietary) firmware to work. Fortunately, although the driver available from Realtek does not include it, it was included on the disk, and is also available in the Billion driver from their website. So, once you have put the firmware in the right place, the device just works.

Here are the steps to get it working (you will need to have RPMFusion enabled, and run these as root).

Code:
yum install kmod-staging unzip
depmod -a
wget http://au.billion.com/downloads/3011N/3011N_Linux_Driver.zip
unzip -j 3011N_Linux_Driver.zip "*rtl8192sfw.bin" -d RTL8192SU

[Code].....

The main downside here (apart from the obvious) is that you will be relying on RPMFusion to build an updated kmod-staging version when you get a Fedora kernel update. Sometimes this might not happen before you get your kernel, so when you reboot, you lose your wireless (because there's no driver). If so, boot to your older kernel for a while, or build the driver yourself, or create an akmod instead of kmod.

Ubuntu Networking :: Realtek 8185 Not Working ?

Feb 15, 2010

I am brand new to ubuntu (I installed it about 2 hours ago on my new PC). Everything so far has seemed really easy and straight-forward, but I am having problems trying to connect to my wireless network.

I have a Realtek 8185 wireless card, and have the disk with the inf file on it. I installed ndisgtk but when I pointed it to the inf file, I got an "error while installing" message, then it showed up in the list of currently installed drivers in ndisgtk but as an invalid driver. I'm not really sure what I'm doing wrong.

I actually have another wireless card in my old PC (a belkin of some sort) - would I be better off using that? I'm using an ethernet cable at the moment and it works absolutely fine, I just plugged it in and off I went.

Ubuntu Networking :: RealTek 8192e And 64 Bit Amd Not Working

Jan 1, 2011

I have tried ndiswrapper using 32 bit and 64 bit winxp drivers and the 32 bit driver just doesn't work period (as expected.) The 64 bit driver locked the system up completely and I ended up reinstalling ubunto. I have now reinstalled and updated and upgraded ubunto 10 times in the last 3 days of trying to get this to work and need some external!

using
Code:
lshw -C network

I do see my network card and driver.

Where I am at currently: I have a fresh install of ubunto 10.04 with it upgraded and updated. I do not have ndiswrapper gtk installed and I have not downloaded any drivers for the wireless card.

Ubuntu Networking :: Driver For Realtek RTL8185 On 10.10 Not Working?

Oct 4, 2010

when I updated from 10.04 to 10.10 beta, I lost my wireless on my Gateway MX3410 laptop. In 10.04, the wireless Realtek RTL8185 card was auto-detected, worked with the default driver.

So I installed the linux driver version of Realtek RTL8185. Although the driver shows up in the "Additional Drivers" panel under "Administration", the computer is not recognising the driver.

Below is all the specs of the current situation.

OS: Ubuntu maverick (development branch)

Ubuntu Networking :: Get RealTek RTL8111 Wireless Working On 10.10?

Oct 20, 2010

The Realtek RTL8111 wireless does not work in Mint 10 or Ubuntu 10.10. Works perfectly in Mint 9 and Ubuntu 10.04. No proprietary driver necessary. Has anyone managed to get it working in Ubuntu 10.10? : You can click the one you want to connect to and enter your security key. I just use WEP because it's easy. I enter the key and the system just tries to connect until it times out. You can repeat this process indefinitely. Wired works fine but after any available updates are installed, still no wireless capability.

Ubuntu :: Realtek Alc650 Audio Not Working On Intrepid Ibex

Apr 15, 2009

Just installed latest Ubuntu (intrepid Ibex) on my DFI Ultra Infinity II system. It has onboard audio via a Realtek ACL650 chipset. Unfortunately, no sound. Have searched various forums, etc. and found recommendations to download the ALSA driver from realtek, but those posts are from ~2007 and the drivers are dated from back then as well. Nobody present-day seems to be suffering audio problems with this motherboard or chipset. I did install the 2007 realtek driver, but no change. What logs can I check?

CentOS 5 Hardware :: Realtek 8169SC Network Card Not Working

May 28, 2010

I am not very experienced using Linux but I never had big problems with Ubuntu. Now I am busy writing my PhD thesis and therefore I had to install CentOS to use one lousy program that I could not get to work under Ubuntu. However, it seems to be quite fine and it is working well besides one fact: The network card stopped working. In the beginning it was working fine although the speed was only on the level of 100mbit. The switch and the LED on the card indicated gbit connection, though. I tried to install the driver for the 8168 card which reduced the card to 100mbit (indicated by the LED on the switch and the card).

Ethtool indicated it was gbit capable but I couldn't activate it. After reading more and more I figured I have to use the 8169 driver again and live with the 100mbit. Unfortunately, after uninstalling the old driver and reinstalling the driver 8169 the network isn't working at all anymore. The network-manager displays the card as inactive and when I try to turn it on it complains about the wrong mac address, which I am not able to change to the proper one. I am using CentOS 5.5 with the latest updates.
