Ubuntu Networking :: RTL8191SE Wireless Connects But Fails?
May 24, 2010
I have a Compaq Presario CQ42-195TX laptop with Ubuntu 10.04 (64-bit) installed on it and fully updated. It has a Realtek RTL8191SE wireless chipset which I am having trouble with - its wired connection is working perfectly.After starting up, I am able to see and connect to wireless networks. Once connected, the wireless functions correctly for a very brief period (under 10 seconds) in which I am able to access the Internet and so forth. The connection then stops working - although it doesn't get disconnected. When I say it "stops working", I mean I can no longer access the Internet and trying to ping the router gives me a "Destination Host Unreachable" error. If I disconnect from the network I cannot reconnect, nor can I connect to any other network.- though I can still see the list of available networks.
I thought that maybe this was a 64-bit issue, but I tried the Ubuntu 10.04 32-bit live CD and experienced the same problem.Please note that while this thread is about the RTL8191SE chipset, the RTL819xSE chipsets all use the same driver.Below are the results of various commands while connected to the network but after the connection has stopped functioning correctly:lspci -nn | grep "Realtek"
I have a Toshiba Satellite L655-S5061 laptop and dual-boot Windows 7 and Kubuntu Lucid Lynx. Windows detects and connects to the wireless network just fine, but in Kubuntu it will detect the network but can't connect to it. Sometimes Network Manager will say it's connected, but Konqueror can't load any websites. Plugging in an ethernet cable doesn't give me access to the internet, either.
I am trying to connect to a windows 2000 VPN server at work, with my current settings in DOES connect to the VPN and i can ping the domain server which is 10.1.1.2 but the first issue is i cannot ping the other computers on the network(via hostnames) can't remember the ip address of the other machines . second issue is when the connection is established and i RDP into 10.1.1.2 ok great i am connected to the server but any interaction in the RDP session even moving the mouse on the screen kills the session and the VPN connection fails.
Running Ubuntu 10.04 LTS 64Bit
Image of current settings in network manager:

How To: Uninstall/Remove Old Wireless Driver to make way for New Driver (RTL8191SE)?
Here's the new driver:
I have been having trouble with my wireless connection intermittently disconnecting and reconnecting repeatedly (sometimes every couple of seconds). I posted a thread about this here on Ubuntu Forums titled: Ubuntu 10.45 & NetworkManager Applet 8.0: Connects & Disconnects Frequently.
I've got a Zotac MAG HD-ND01 with XBMC live installed. This is built on Karmic Koala and runs very nicely through the wired NIC.
I configure the box using a cable. I'm using WPA2-PSK and it is clearly authenticating OK.. It gets an IP address.. the AP shows a connection to the box. My XP laptop connects to the access point OK.. just can't connect to the box via the wireless, and it can't see the network using wireless.
I have followed a number of threads on connecting Atheros 9XXX wireless [URL] but no joy.
Also, can Ubuntu connect to the AP at any speed greater than 54MB? My windows PC connects at 144MB+ . Will ndiswrappers connect at those sorts of speeds?

My wireless connection always worked. When I log in, I already have internet access.I went on holiday and connected to several other networks.Now the laptop will not connect anymore. Sometimes after 5-10 minutes.When I forse to connect ("Connect to hidden wireless network), the laptop connects after several seconds. But not automatically.My wireless modem uses WPA2, MAC filtering and has a hidden access point.I use Ubuntu 10.4 on a HP Probook laptop. In "Network connections", under "Wireless", the "Connect Automaticly" and "Available to all users" are selected. When connected, the signal strenght is very good.
I've recently installed release 11.04 and am trying to get wireless networking operational. I'm using a netgear wg111t usb wireless adapter. I've installed ndiswrapper and have got the netgear windows drivers installed ok. My problem is when I try to connect wirelessly I get a system crash, think it tends to be called a kernel panic in linux. The network connection is confirmed and about 5-10 seconds later the crash happens. I've updated the linux kernel to 2.6.39-0-generic but thats not helped.
I can connect with a cable but that is somewhat limiting.
I recently installed UBuntu 11.04 and dual booting it with WIndows 7, I really like linux and considering removing W7 and only have Ubuntu But the problem is I can only connect when using an ethernet cable, when it comes to wirelesss, I type my password, yet a ring keep rotating and it never connects. My laptop is HP-G62
I am using Fedora 8 on my laptop, newly installed, I can see the network card(Linksys WPc54G v2) and Network Manager sees the wireless router, however as soon as I tell it to connect my computer freezes and I have to restart. I searched for solutions but all I found was Ubuntu problems.
Actually it seems that the trigger is when the keyring comes up and asks for a password. As soon as I start typing the pass it locks.
I have a Thinkpad X100e with Realtek 8191SE wireless, which I am having little luck getting to work with WEP in Debian Squeeze.The only Linux driver for this wireless chipset is r8192se_pci from Realtek (out-of-tree, but GPL; includes binary firmware); I can vouch for this, having built wireless-testing from git on the 19th. After installing the headers and building the driver from source (no warnings), the module loaded fine.When I try configuring wlan0, it appears to work.
I go ifconfig wlan0 up iwconfig wlan0 key <key hidden> essid <essid> iwlist wlan0 scanning iwconfig dhclient wlan0 #I've also tried with 'busybox udhcpc -i wlan0'
iwconfig shows association has succeeded; both dhclient and udhcpc succeed in getting a dhcp lease.But if I try accessing the network (busybox ping or links2), I get "Network is unreachable"; aptitude reports a 'temporary failure to connect'.If I do not boot with the 'quiet' boot parameter, r8192se begins randomly spewing messages through the console right about this time, indicating that the driver may be randomly disconnecting.
Kernel: linux-image-2.6.32-5-686 Debian squeeze, installed via debootstrap from Ubuntu.
Under Ubuntu, this driver is patched into the kernel; I have a functional connection with WEP under 2.6.35-24-generic on Ubuntu 10.10.wpa_supplicant on Ubuntu, however, causes random disconnects. Switching the card is not really an option, as Lenovo has a BIOS whitelist that prevents booting with an 'unauthorized' wireless card.
First- clean installation of Ubuntu 10.04, with default network manager installed, I had a taskbar icon, and it could see the available wireless networks, could not connect to them, even the ones with no security. Purged all network manager files suggested in various threads here, Installed wicd- it could see all available networks, could connect to unsecured networks, but not to my own secured network. Password was correct in the wicd/configurations file. Removed wicd, and reinstalled network manager from synaptic. I have to network manager applet. When I try to add it to the notification area with alt-f2, applet-nm, I get a brief flash of something in the notification area, but no applet.
System=>Preferences=>network connections shows no wireless connections, but I'm obviously connected to something (probably my neighbors unsecured network) since I"m reaching this webpage. I tried to run sudo wpa_cli from the terminal to see what network the computer is connected to, and it gives me this error:
Quote: Could not connect to wpa_supplicant - re-trying wpa supplicant is installed according to synaptic Various troubleshooting output:
I've configured an openvpn server on a wrt54g using dd-wrt firmware. I can connect from the command line...at least it appears to connect, but I am unable to access any resources. Trying to use networkmanager's openvpn client fails every time. Everything I find googling relates to Ubuntu, so just for kicks I booted into my Ubuntu partition for the first time in months....and the wireless lan disappeared when I restarted network manager, which is why I don't use Ubuntu in the first place, so much for the "easier distros". I'm assuming there are people successfully connecting to openvpn servers from Slack. I could definitely use a pointer.
I am getting trouble with knetwork manager. I created a new connection by scanning and connecting using knetwork manager. But every time connection gets disconnected and ask for password and again it connects.
No wireless networking. The ethernet works fine, and the wireless interface itself works well in Windows 7 (dual boot). Tried: Ndiswrapper, notoriously quirky, does not seem to work with the XP driver (the oldest driver available for the RTL8191SE). The linux driver offered on the manufacturer's website lacks any installation instructions. I have no clue how to install a linux driver. SUSE seems to have two network managers that are constantly complaining about control: Network Manager and Yast. Neither are great and I am left missing my Ubuntu.
However, my audio only seems to work on SUSE. I have tried almost every distro on this machine. Ubuntu lacked sound and wireless, Fedora played startup sounds, but would not play an mp3 or wav file (fiddling with the mixer did not help). And Fedora also lacked wireless support. PCLinuxOS, my favorite, lacked sound and wireless. Tried some oldies too. ELE, DSL, Puppy, Ubuntu Netbook remix, Vector, Browserpuppy, Crunchbang, Cruncheee (just for experimental sakes) and probably others I am not remembering. So far, installing a free linux distro has cost me 14 dvd-R's and countless hours of installing, reformatting and reinstalling. Part of me really wanted crunchbang to work, as I love the minimalism and blacked-out theme.
I need wireless network access. The wireless light remains red in Linux and pressing the key does nothing to start the device. In Windows 7 it always lights white and works perfectly. Why hasn't SUSE adopted a gui for ndiswrapper? Other distros have it. Why is my brand new laptop, which is by no means abnormal in make or configuration, not 100% supported natively by any Linux distro? I just updated to the new kernel yesterday. So I should be running the most modern operating system available. Yet good-ol Windows 7 is my only fully functional environment.
I just upgraded to natty last night, and everything is working fine except for the network manager. I can enable and configure the wireless card via bash, but the network manager widget will not manage the wireless card.
When I first boot up, the "Enable wireless" check box is greyed out. After I enable the card via the terminal, the "Enable wireless" check box becomes ungreyed, but every time I click it, it instantly unchecks itself. I feel like Currly from the Three Stoogies. Check, uncheck, Check, uncheck.. "Slaps face repeatedly."
Dell mini 10 with ubuntu 10.04/windows xp, connecting to linksys wrt54g. Connected when I was using 9.10, has worked for several months since 10.04 was installed. Still works if I boot XP, but, when booting Ubuntu, router won't accept the passkey which I obtained from my wired computer. I've glanced through a bunch of posts and see several which are close, but no solution. Only cause that I can think of might be a shut down while connected. I say that because it was working and I had no need to change settings.
I upgraded from 9.x to 10.10. Under 9.x my wireless usb dongle worked correctly. After upgrade it does not. I checked the dongle on another machine and it works correctly. I inserted a usb memory stick and the system found it as a drive correctly. I assume from this that both the dongle and usb port are ok. The wireless device is a D-Link G122 A2 which is on the supported list (it ran out of the box on 9.x). The link light did not even come on. So I installed ndiswrapper and the windows D-Link driver (note that this was not needed in 9.x). Now the link light comes on and the wireless router is found but the unit will still not connect.
The log file entries on dongle insertion are as follows:
It appears that the problem is with wlan0 not being ready. If this is the case how do I make it ready?
When connecting to any wireless network, DNS lookups completely fail to work. Over a wired connection, there's no trouble.
I can ping machines by IP address, and I can dig and nslookup domain names using the DNS servers assigned by Network Manager or by myself. When I try to ping by domain name, however, nothing happens. Similarly, I cannot ssh into machines by domain name or browse the web.
My wireless card (Intel 4965AGN) is managed by Network Manager. The issue is seen regardless of whether DNS servers are obtained automatically by DHCP or assigned by me through Network Manager. This started about a month or two ago while I was using Maverick and presents again with Natty. I dual-boot Natty and Windows 7, and everything works fine in Windows.
Somehow, this seems to be linked to Nautiluswhile connected to a wireless network, Nautilus won't open, my desktop icons won't show, all that jazz. If I'm connected to a wired connection at login time, Nautilus works fine.
I've managed to workaround the browsing issue by setting up an ssh tunnel through a machine at school and forwarding Firefox's DNS resolution through that tunnel. But I'm at a loss as to how to resolve the core problem.
Here's some diagnostic info. I've modified my IP and hardware addresses below.
I've tried all the basic steps killing and restarting Network Manager, renewing my DHCP lease using dhclient, restarting /etc/init.d/networking. I'm at the end of my rope, though, and ready to reinstall. I'd be much obliged if anyone can think of a less "Microsoft" solution.
My wireless adapter connects to my WPA2 network perfectly, but when I run firefox it says it can't load the webpage, no matter what page I go to. Also, downloading new software doesn't work either. Any ideas please?
The nm-applet starts automatically as it should, and also tries to connect to the local, wireless LAN, but always fails its first attempt. If I click the icon and ask nm-applet to connect again, it always succeeds.
The server, running the wireless LAN, never sees the first attempt to connect, so no wonder this attempt fails. But it would be nice to make it succeed!
I have an Atheros AR242x card. It can see my wireless network (WPA2). When i attempt to connect to the network it asks for the WPA2 passphrase. After entering the password it begins connecting but hangs up for about 3 minutes before saying wireless disconnected. The wireless worked for one day on a fresh install (Ubuntu 10.04)and then started doing this.
I recently installed Ubuntu 10.04.1 LTS and have it set to dual-boot with windows 7 on my gateway tablet PC. Since installing, sometimes when I suspend or reboot, my wireless does not work. To be more clear - it is working fine, then I either suspend/reboot, then I come back and no wireless networks show up at all. I can still connect with ethernet cable though. I can solve it by rebooting multiple times (usually around 1-5 times) and then it (magically) seems to work again. I have also tried switching from network-manager to wicd, but the problem persists. With both network-manager and wicd, I've tried simulating a reboot for the wireless by using the command 'sudo modprobe -r iwl3945 && sudo modprobe iwl3945' (network-manager) and 'sudo /etc/init.d/wicd restart' (wicd), but these do not seem to work.
I'm using the new opensuse 11.4 with KDE desktop. I can connect to my WPA2 personal network fine, but some other networks, like a WPA2 enterprise network connects, but no Internet(pinging too) resolves.
