Ubuntu Networking :: Connection Stop Working With RTL8187 Wireless Adapter After Few Minutes

Feb 4, 2011

I buy a new usb network adapter (Through DX), when I try to use it in ubuntu or BackTrack4 Final it is working, and connecting networks even with WPA encryption. But after few minuts it stops working totally. It is showing that I'm connected to the AP but web sites do not respond.

Notes:
- I have another PCI Wireless adapter which works fine.

- The problematic adapter works great on windows.

- A driver CD came with it, including a linux driver which I wasn't succesfully installed.

- A BackTrack3 Disc came with it, claming by the instructions that the adapter will work with it. I didn't try it because i have backtrack 4 final.

It took me dozens of surfing the web hours, and too many restarts,

Ubuntu Networking :: AWUS036H - RTL8187 Wireless Adapter Slow

May 29, 2010

This is wireless adapter: [URL]... USB/Detail.bok I have 2 AWUS036H Wireless USB adapter that uses the RTL8187 Chipset connected to a USB 2.0 Port. It is very slow when I try to go to websites or download anything using Ubuntu 10.04 Lucid Lynx. The max speed I can get out of it is 135 Kilobytes per second when downloading anything. But when I am on Windows I can max out 2.6 Megabytes per second. I have been trying to find a solution but have found none. When I look at the light on the wireless adapter and compare it to what it looks like on both Ubuntu and Windows. It seems that the wireless adapter light is dimmer on Ubuntu. So I was thinking it was txpower set very low. I changed it but no success on changing speed. I am using WPA2-PSK which obviously uses AES. I have also tested it while it is in WEP and when it is Open with no change in speed. Speed results Ubuntu 10.04: Speed results Windows 7: I changed the settings to Megabytes on those speed results.

Ubuntu Networking :: Wireless Connection Drops Out After 15 Minutes?

Jun 13, 2011

Having struggled to get the wireless connection at least working I find it drops out after 15 minutes or so. When I check for wireless connections I can see none at all and the "Disable/Enable wireless conncection" has disappeared, the Network one is still there. I get an auto reconnection if I reboot and all is well for another 15 minutes. Is there any way i can recover the situation without a reboot? I am trying to install the hplip-3.11.5 driver for my new wireless printer,the program take a while to install and by the time it has started looking for the printer the connection has dropped out. I can't be sure but I don't think it was dropping out before I connected the printer using my wired pc. All good fun but I'd like to get it sorted so I can get the engine back in my motorbike, the sort of technology I prefer!

Ubuntu Networking :: Dell 1545 - Wireless Connection Drops After A Couple Of Minutes?

Apr 10, 2010

I have a Dell 1545 laptop with ubuntu 9.1 32-bit installed (the 64-bit had a bug with the wireless drivers which is why I have not used it). Initially, the laptop worked well with the wireless (a sky router with WPA security) but now, the wireless signal drops after a couple of minutes of usage. I have to reboot the laptop or sometimes reboot the router as well to regain the wireless signal. I am using the Broadcom STA proprietary wireless driver.

I have an older dell inspiron 6400 as well with the same OS and driver and it works perfectly without any problems for hours / days.

Ubuntu Networking :: Wireless Connection - Takes Upward Of 10 Minutes And Over 20 Times Of Me Clicking 'Connect'

Jun 20, 2011

I have been having trouble with Ubuntu 11.04 when connecting to the Internet via Wireless Networking. It will connect, and has good speed once it connects, however it takes upward of 10 minutes and over 20 times of me clicking 'Connect'.

Is there a way to connect to a wireless network quicker? My network is unsecured and without a keyring. It is not only slow connecting to my network, but the network of other's.

Fedora Networking :: Worthless Wireless Connection \ Works Well For A Few Minutes Then Has A Period Of Inactivity - Then Slow?

Nov 24, 2009

I'm running Fedora 12 on an Acer Aspire One with KDE. The built-in wireless works without a problem EVERYWHERE except at work. It's a shared wireless connection using WPA/WPA2 security.I can connect but it's "hit-and-miss" if I can do anything with it. Somedays it works well for a few minutes then has a period of inactivity - then slow - randomly receives...It worked flawlessly when the computer was running Windows7 no one else has connectivity issues but I'm the only one using Linux.

Ubuntu Networking :: Wired Connection Stop Working?

Oct 25, 2010

Ubuntu 9.10. Everything works fine until yesterday when I cannot connect to network. My lan card is Realtek PCI and is present on system (i can read mac address and all settings). In connection manager I was try to set everything manually (IP, netmask, gateway and DNS) or leave automatic - without success. I am connected to router. I don't want to feed "log-hungry" people because how to resolve ubuntu lan problem can help me (not someone who will want to try). I cannot connect manually because there is no option when I click on network icon (I can just uncheck connection, but that's all). I can't even access to my router (from computer with Ubuntu, because I can access from another computer). All logs shows lan card proper. Windows XP on the same computer booted from another HDD works fine.

Ubuntu Networking :: Wireless Adapter Not Working / Fix It?

Aug 26, 2010

As the title reads. My wireless adapter does not work when I boot from the Ubuntu 10.04 LiveCD. The adapter in question... tricky. It's this one: [URL]...- however, aside from a mention in one of the comments to a "Ralink RT2780", I don't see any reference to a make/model.

The software that ships with this product is indeed Ralink-branded, but again there's no mention of a specific make/model. So I assume it's just a driver issue, however I've no idea where to begin in my search for one as I can't identify its model number.

Ubuntu Networking :: WG111T Wireless Adapter Not Working?

Feb 28, 2010

I have been searching for days on end trying to get my machine to detect my Netgear WG111T wireless adapter...and I've gotten absolutely nowhere at all.Most tutorials suggest I use ndigstk(sp?), which allows me to use Windows drivers for my adapter. I've been told many times to use the wg111t.inf file, but all I've been able to come up with is the w11t.inf file. Whenever I start up the Windows Wireless Drivers application, I usually get a popup which tells me "Unable to see if Hardware is detected"--yet when I hit the OK prompt, next to the w11t.inf file, it says "Hardware detected --Yes", yet I still have gotten nowhere. I grasp some basics of Linux, but overall I'm still pretty new to it--and I have a big headache from the whole thing.

EDIT: I forgot to mention, my install is 9.04, so if 9.10 resolves this, how would I go about upgrading without downloading an ENTIRELY new disc (I have a horrid internet connection, it'd take HOURS to download the 699MB ISO, so perhaps make that a last resort)

Ubuntu Networking :: Wireless Adapter Not Working After 10.4 Upgrade?

Aug 7, 2010

I upgraded to Ubuntu 10.4 on my Dell Inspiron 6400 yesterday (32-bit). Everything was running great, but when I turned it on today my wireless adapter is no longer working and the hardware switch doesn't do anything. It's working in Windows fine so it can't be the hardware.Here is some information:

Adapater name: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)

Code:
iwconfig:
wlan0 IEEE 802.11abg ESSID:off/any[code]....

Restarting the network with 'sudo /etc/init.d/networking restart' didn't work.I've tried Ubuntu several times before but usually there is one small issue which makes me go back to Windows. I love 10.4 so I hope I can get this working so I can stay on Ubuntu!

Ubuntu Networking :: Wireless Adapter Not Working After Wlan.conf Update

Jan 19, 2011

I updated Ubuntu to 10.04 after which I noticed the wireless indicator lights on my HP laptop were continually flashing between blue and orange and network performance seemed slow. I did some searching and found and implemented the following change to stop the flashing:

gksudo gedit /etc/modprobe.d/wlan.conf

Copy and paste the below line:

options iwlcore led_mode=1

Since making this change the wireless connection is shut off and I can;t get it to work at all. I first tried simply to remove the change to get back wher I was, but I can;t do that. Can sopmebopdy toell me at least how to get rid of this wlan,conf file ( it was created by the above command) so I can start over?

Coincidentally since making this change my Windows Vista OS fails to start because of errors attributed to a software or hardware change, of which there were none other than the Ubuntu wlan.conf change. . It may be unrelated but I am suspicious of the coincidence. I am running Vista and Ubuntu in a dual boot configuration and all ha run very well until I did the Ubuntu wlan.conf change.

I am now attempting a complete recovery of my Vista system, since it seems irreparably broken. Again coincidence or not?

Ubuntu Networking :: Atheros AR5001X+ Wireless Network Adapter (rev 01) Not Working

Mar 3, 2011

I have a Toshiba MX35 laptop it's a little old but does the job. I'm have a problem getting the wireless to work. I can boot a live CD either Ubuntu 10.10 or Fedora 14 and they will see the wireless card. The card is Atheros Communications Inc. Atheros AR5001X+ Wireless Network Adapter (rev 01).

I have Ubuntu 9.10 installed and that is the OS that is having the problem seeing the wireless. The computer will not handle Ubuntu 10.10 (at least it won't handle the desktop effects under Ubuntu 10.10) but handles them just fine under 9.10 and that's why I have 9.10 installed. I really need the Wifi to work because I'm going to travel in a few days.
