Networking :: Fail To Connect To WLAN With Realtek 8172 Device
Nov 9, 2010
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.

I bought a Toshiba A500 two days ago (was in a rush, my old A200 had a catastrophic failure) and the wireless doesn't work. I have two network related devices listed with lspci:
Code:
07:00.0 Network controller: Realtek Semiconductor Co., Ltd. Device 8172 (rev 10)
0c:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 03)
[Code]...
To my question: I found this article (HOWTO: Xplora E16 Ubuntu 9.04 32Bit and 64Bit with wired and wireless networking - Novatech Community Forums), which seems be consistent with my situation (wired connection works, wifi doesn't and my kernel is 2.6.31). I ran the installation and it appears it worked...BUT, is this going to create major problems down the line (kernel upgrades, etc.?)

(For the record, I have already read the other threads. Either they don't work for me or are too difficult.) My laptop is an Acer TravelMate 250. I have installed Ubuntu 10.10 (2.6.35-28 generic i686) after erasing Windows 7. At first, the usb wireless adapter worked. Then, I restarted the PC because of some updates and it didn't work anymore. In "edit connections" I find "Auto SpeedTouch8350DB" which is the wireless connection (on my sis's computer it works). When it tries to connect, I'm asked the password but it doesn't work.

I bought an RTL8187L USB wireless adapter, and have had trouble getting it to work. I have managed to get it to work via manually configuringtime, but lost that configuration, and now it is once again not workingThe root issue appears to be (if I'm understanding correctly what I'm seeing) that when I connect, routes don't get setup properly, so when network manager (or WICD, which I've also tried) get to the DHCP step, my wireless router can't be reached by dhclient.
This is on Ubuntu 9.10, and I'm using the updated driver from realtek.com, btw, though the in-kernel driver was exhibiting the same behavior.So, two questions:- Is anyone familiar with this problem, and is there a fix available?- I believe I can work around it by setting up routes manually (e.g. with a post-connect script in WICD), but after staring at the "route" manpage, I'm not 100% sure of the commands. My router (a FIOS MI424WR) is my DHCP server, and is at 192.168.1.1, and route -n on a working PC (wired connection) gives:
Code:
dave@MinasTirith:~$ route -n

I've just installed Ubuntu 10.04 on my samsung n150. It has the 8192 device in it. Have installed ndiswrapper, however cannot get the drivers for it. How to fix/where to get the driver from so I can get my wireless card working again.
On lspci:
00:00.0 Host bridge: Intel Corporation N10 Family DMI Bridge
00:02.0 VGA compatible controller: Intel Corporation N10 Family Integrated Graphics Controller
00:02.1 Display controller: Intel Corporation N10 Family Integrated Graphics Controller
00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 02) .....
I think the driver may be there, however I just can't 'enable' it. On my laptop there is a blue light saying that wifi is enabled however who knows.

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.

Running Linux mint 10 After the installation the wireless connection worked but it was very weak and intermittent. The icon would show 1 bar or none. iwconfig showed the rate at 1Mb/s. The same card worked fine in windows and on a 32bit version of linux. Installed new driver from realtek. Now the iwconfig readings look good and the icons shows 2 and sometimes 3 bars. But it will not connect at all! I even turned off all security on my router but it would not connect.

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.

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

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:
Code:

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 desktop that has a d-link DWL-520 wireless card, which was working under Windoze. Today I installed Centos 5.4 on the system , which went cleanly. I then used Network Configuration to set up the wireless card. I specified to use DHCP, set the SSID and authentication password. When I tried to activate the card I get these error messages
Error for wireless request "Set Mode" (8B06): SET failed on device wlan0 ; Operation not supported. Error for wireless request "Set Encode" (8B2A): SET failed on device wlan0 ; Invalid argument. Error for wireless request "Set Encode" (8B2A): SET failed on device wlan0 ; Invalid argument. Determining IP information for wlan0.
The hardware manager seems to have correctly identified the card and chipset, (Intersil Prism 2.5) and installed driver hostap_pci which came with the distro. This web site seems to suggest that this is the correct driver: [URL] searching forums I've found a few references to these errors, but they were from several years ago, and for different distros and cards. I did find a reference to using Network Manager to configure the card instead of Network Configuration. I started the NM service and configured a connection using it instead, but still no luck.

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]...

I have just installed the last FC distro, and everything works good, except the wireless network.I have a Linksys N-Ultra WirelessN USB wifi card, model WUSB600N.It uses the rt2x00 driver, concretely the rt2870 driver (at least, thats the driver included in the original device drivers CD).Right now, the problem is that i don't know how to make my Fedora 12 to enable and/or connect to internet.

I just upgraded to 15 and was wondering if it was possible to specify which devices to prioritize a route through. I have my machine, a laptop, connected to my family's router for an internet connection and a wired connection to a personal router for a faster and private connection between my other two computers and a network storage device. Whenever the laptop is connected to my personal router everything goes through it and it can't connect to any external web sites. But when I unplug it and go only on my family's wireless everything is fine, except I can't connect to the storage device since it has no external connections.

I have a ZTE 3G USB modem (MF645).
When I plug it, 5 devices appear: /dev/ttyUSB[0-4]. The modem device is /dev/ttyUSB2, and I can successfully connect wvdial on it.
NetworkManager detects the modem, however, it tries to connect to /dev/ttyUSB1 instead, and fails.
How does NM decides which device to connect to?
Is it possible to instruct it to connect to a specific device?
