Ubuntu Networking :: Can't Find Wireless N Networks With RT2860
Feb 1, 2011
I went out and purchased a Sabrent PCI wireless 802.11n card with the RT2860 chipset because it was on the ubunutu compatibility list and has linux driver available from the manufacturer. I was impressed that the card worked in wireless G mode out of the box, which is a great start....
However, I can't find any wireless N networks. Dual booting I can find/use my N network, but in ubuntu I can only find my G network. This is somewhat frustrating because I bought this card and a new (read: expensive) Linksys E3000 router specifically to run a nice new N network...
I have downloaded, made, and installed (reboot) the latest driver from the manufacturer, but it still won't find any N networks. I found a few posts by searching here and google that alluded to changing this line: "HT_OpMode=1" (from 0 to 1) in the config file RT2860STA.dat located in /etc/Wireless/RT2860STA/ and a reboot. It didn't work for me.
Frankly all this rebooting is starting to **** me off ... I have spent most of last night trying to setup my 180$ wireless network and its still no better than the freebie DDWRT54g based wifi it replaced. I am frustrated, perhaps someone wiser in the ways of ubuntu and wireless N can shed some light on the situation....
I forgot to mention I am on Karmic Kola, amd64 with the standard gnome.

For some reason, ubuntu cannot find local wireless networks. In fact, the Broadcom wireless card Ralink RT5390 802.11b/g/n seems to be incompatible with ubuntu. I've tried numerous 'solutions' on the Internet, but none of them seem to work on my computer. Tutorials I've visited have recommended downloading the b43 drivers from the Synaptic package manager and also the bcmwl-kernal-source package. Nevertheless, the wireless never turns on and Additional Drivers never shows anything at all. After several exasperating hours of trying to get my wireless running I've decided to turn to the forum for help. I'm sure there's probably more information I should supply, but I'm honestly not sure what that would be.

i'm running ubuntu 10.04. i've followed these instructions:[URL]that got the light for the wireless on my laptop to light up but it doesn't seem to be able to find any networks.when i click on "connect to hidden wireless network" and enter the details + encryption code. it spends a few minutes trying to connect before asking for my encryption code again but i know that the code i entered is right.i'm using a belkin router with wpa/wpa2 encryption. but i think it's a problem with the wireless on my laptop rather than a problem with my specific network because under windows on other machines in my house i can see some of my Neighbours networks

I had a problem with using ndiswrapper to install Windows driver on Netgear WN511TA wireless adapter card. Problem solved by replacing Netgear WN511TA with Airlink101 AWLC6080 PCMCIA wireless adapter to work in my triple-boot XP Pro/Ubuntu Karmic/openSUSE 11.2 Toshiba laptop and using the latest Linux driver version 2.3.0.0 dated January 29, 2010 from Ralinktech site. I followed driver instruction in a Ubuntuforums tutorial (Howto: Ralink RT2860(m) PCI(e) RT2860...on Intrepid).
I am wondering if I can use the same Linux driver (RT2860sta) for openSUSE 11.2 on my triple-boot XP Pro/Karmic/openSUSE laptop, ie. copying over instead of building and compiling driver from source again, because I don't quite understand the build instruction given in the README file of Ralink's Linux driver file. Specifically, I don't know how to "define the GCC and LD (?) of the target machine, and define the compiler flags CFLAGS(?), modify your need (?)", etc. I already have gcc, cpp and make installed on the Ubuntu and openSUSE parts of my machine. I did try ndiswrapper in openSUSE but it doesn't work for the Windows version of the latest Ralink driver (error: invalid driver rt2860.inf).

My wireless download rate is absurdly low (0.3 mbps) compared to a faster upload rate (1.5 mbps). My girlfriend's laptop running windows gets much higher download rate (20+ mbps).

I've been happily using this lappie with LTS but wanted to try out 11.04. It looks great but wireless has been an issue:
1. No wireless during install
2. Had to manually blacklist the rt2860pci etc modules
3. Wireless still not resuming after suspend
05:00.0 Network controller: Ralink corp. RT2860
Subsystem: Ralink corp. Device 2790
Physical Slot: 0-2
Flags: bus master, fast devsel, latency 0, IRQ 18
[code]...
The latter manual mod improved things slightly but still no cigar

I have a MSI A6000 laptop (the laptop that won't accept 10.10 because of the nvidia card) so finally I opted to get Ubuntu 9.10. I successfully installed with a dual boot.
There are two problems though that I have ran into.
1. Ubuntu 9.10 is not picking up wireless networks.
2. The Ubuntu graphics (icons, taskbar and windows) are much to large. I am guessing this has to do with the Nvidia card (nvidia GeForce 8200m G).

well traded my desktop for it and its a Dell Inspiron 1721. The Wireless was working fin when it had Windows vista on it but when I installed Ubuntu 9.10 The wireless just seemed to not exist. The LED wouldnt even turn on. So I installed wicd and then the wireless icon began working but it still won't find any wireless networks.

I like to do a lot of my tasks through the command line, and was wondering, is there a way to see all the wireless networks available in the terminal? I tried 'iwlist scan', and it said all the interfaces do not support scanning. Is there anything I can do?

I have an HP Netbook that has Linux MintI have absolutely no issues with awired connection, however my internal wireless will not search and find wireless networ in range. It appears I have one saved (my home network) and I can connect to that, however, if I take my laptop to school or work, it will not find any networks to connect to. On a side note, I have no icon on the taskbar indicating wireless, and I used to have one. I have no idea where it went or what happened. I can answer most questions you may have but im a relatively new linux user (but I have a coworker that "knows all" and could help answer a question that I cannot.

I am using 11.3 (64-bit gnome) and have a new Tenda w322p wireless n card, this works absolutely fine under windows, but I also bought it due to reviews saying it worked with linux. The card appears in network settings as RaLink WLAN controller and uses kernel module rt2800pci, I have also tried typing in the network ssid etc manually but it hangs on exiting network manager (will post what it says later, after writing this) I used drivers from here:Ralink corp., and used the rt3062 one(5th one down?)
for lspci
Code:
00:00.0 Host bridge: Intel Corporation 82X38/X48 Express DRAM Controller (rev 01)
00:01.0 PCI bridge: Intel Corporation 82X38/X48 Express Host-Primary PCI Express Bridge (rev 01)
00:06.0 PCI bridge: Intel Corporation 82X38/X48 Express Host-Secondary PCI Express Bridge (rev 01)
00:1a.0 USB Controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #4 (rev 02)
00:1a.1 USB Controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #5 (rev 02)
[Code]....
I have also had the same problem of not picking up networks in Ubuntu, not sure if the drivers are 64-bit compatible or something.

I could use Wireless network. I could see several different networks in my range. Then suddenly the network stoppedworking, and I can no longer see any networks under "Wireless networks".The Wired networks works fine.I tried upgrading ubuntu, but nothing changed. Just to confirm, I rebooted the computer in Windows Vista (Dual boot) andconfirmed that Wireless worked fine there. No hardware problem then.The suggestions I have found on this and other forums suggest looking at the output from iwconfig and ifconfig. But since I'm a n00b at Ubuntu I don't know what to make of it.
This is the output:
emil@emils:~$ iwconfig
lo no wireless extensions.

I've been running Karmic since it was officially released on my Dell Studio 17 (specs are in my signature) with a Broadcom wireless half mini wireless card.hen I installed Karmic, it gave me the option to install proprietary drivers for my video card as well as 2 Broadcom drivers, STA and one of the BC43 drivers. I installed all of these, and the only problems I had were with the audio. I spent a few days troubleshooting the audio and finally got PulseAudio set up for my card.
Almost 3 months later, I was making use of my wireless network at home, as I had done plenty of times over the previous 3 months, when I closed the lid (thus putting the computer into sleep mode) and took it to the hospital to stay with my fiancé¥ after her surgery. When I got to the hospital, I couldn't get their network to show up. Network Manager didn't even recognize the network. We had also brought my fianc饧s laptop (same machine with a slightly less powerful CPU and only 4 GB of RAM). She is running Windows 7, which detected the hospital's network with no problems.After trying to ad-hoc the hospital network with no success, I finally just gave up and played Sudoku and toyed with some graphics stuff in GIMP until we came home. Upon returning home, however, I was shocked that my card didn't even detect our home network.
I have been unsuccessful for the past 3 days in getting Network Manager to identify our wireless network. The wired network connects without issue and I am able to make use of a USB Belkin adapter, which identifies all 7 of the various wireless networks in my neighborhood, including our home network.While I would be able to simply carry my Belkin adapter with me in order to make use of wireless networks, I would really like to solve this problem with my Broadcom adapter. I've gone through the Ubuntu Wireless Network Troubleshooting guide, but I still can't get it to workOutput of lshw -C network:
Code:

I can't use my wireless card in slack 13.1 (slack64-current). Looking at the dmesg output I saw that the firmware was missing, so I download it from ralink website.After this I was able to up it with ifconfig. I also was able to see my network with wicd, but after connection I can only transfer very few packets and network becomes unresponsive, no traffic.In slack64 13.0 this same card works fine. I don't even need to install a firmware. how I can make this work in slackware64-current?

Desktop PC with Trendnet TEW-642 PCI wireless N adapter (Ralink 2860 STA driver). Running openSUSE 11.3 X8_64 with KDE 4.4.4. Software Management and KNetwork Manager both identified rt2860STA as installed. However, KNetwork Manager's authentication window keeps popping up every few seconds and I cannot get wireless.
1) uname -r:
Code:
2.6.34-12-desktop
2) /sbin/lspci -nnk:
Code:
03:06.0 Network controller [0280]: RaLink RT2800 802.11n PCI [1814:0601]
Subsystem: RaLink Device [1814:2860]
Kernel driver in use: rt2860
3) dmesg:
Code:
[ 6.270671] rt2860sta: module is from the staging directory, the quality is unknown, you have been warned.
[ 6.275290] alloc irq_desc for 21 on node 0

[code].....
I have downloaded and extracted the latest rt2860.bin file from the Ralinktech website to Desktop but even as root I cannot copy it to /lib/firmware or replace the existing rt2860.bin file in /lib/firmware.

I have been having trouble getting my network card to access networks. I currently am using a wired connection. A while ago when I first installed Linux on this same computer, I got it working by installing the driver. But since I reinstalled Linux, I tried the process again with no success. Can anyone give me explicit instructions on installing the network card driver so I can use it on Linux.

I'm dual-booting Ubuntu 9.10 (upgraded from 9.04) and Windows 7 on my Dell Inspiron 1525 laptop.Ubuntu doesn't recognize any wireless network (both in 9.04 and 9.10); my Windows OS works perfectly well with wireless, as does my wired Internet connection with Ubuntu and Windows.I've had this problem on previous installations of Ubuntu (I've removed and re-installed it several times) but I can't locate the solution anywhere. I've tried numerous fixes that I've found online, but none of them have worked.System>Administration>Hardware Drivers tells me that the Broadcom STA Wireless driver is activated and currently in use

I'm running Ubuntu 10.04 64bit on a Thinkpad T61, and I keep running into some issues with the wireless networks. For a while, the connection works fine (sometimes several hours, sometimes 15 minutes or so--there doesn't appear to be an event associated with it). Eventually, though, the connection disappears; first, though the widgets say I'm connected, nothing will go through, and soon after, it realizes I'm not connected and, moreover, it can't find a single wireless network, despite the fact that it was just fine a couple of minutes beforehand (and other devices still have access to the WLAN, so I know that the router hasn't crapped out). I've tried using wicd, but the same thing happens.

I am quite new to Ubuntu, so please give me easy to follow steps.So, I have just installed Ubuntu 10.10 x64, but cant get my wireless to work. It detects my networks and tries to connect to them - infinitely, whithout success.I have tried it on an unprotected and on a WPA2-personal protected network with the same results.My card is a RaLink rt3090.

I have a pretty beat-up laptop, on which the inbuilt wireless doesn't work, and so I now have an ASUS WL-167g, which is acting up!It almost always connects to the required networks without an issue, but then once I'm connected it's REALLY slow on some of them! For example, while I'm at school, it works flawlessly! And at a couple of friends' houses, it works too! however, at home, and at a couple of other places, despite the fact that it connects, its so slow, that google takes like 5 mins to load and searching for anything on google leads it to time out!! This happens whether I'm right next to the router (full signal strength) or 2 floors up (at like 3 bars strength)!
It's getting pretty frustrating to have to swap my lan cable between my desktop and laptop constantly, and also to not be able to use my laptop away from my desk!Does anyone know what might be going on??Also, while i have you guys here! I have another problem -- with the inbuilt card.. Initially, it wouldn't work at all.. but more recently, it has started to function (it connects and works on my home network fine) the only problem is that about 10 mins after I turn the wireless switch on on my laptop, it hangs! (EVERYTIME) (if it's relevant, my laptop is a SONY VAIO VGN-S46GP). Again, any input would be appreciated!!

I installed Lubuntu yesterday on an older Dell laptop and the installation went fine. The only thing not working after the installation was the wireless. After hours of searching, I was finally about to get it to recognize the wireless card, see wireless networks, and connect successfully by running these commands.code...

I have ubuntu 10.10, and at my house I primarily used wired, and it works fine, and under windows earlier today I was able to locate networks, so my wireless card is working. I'm currently at my girlfriends house, and trying to connect to her wireless internet. When I try to connect, I can't find any networks. I've made sure her network has sharing and discovery enabled, however in my wirelss manager it comes up as blank. There's the option to add wireless manually, but do I really need to go through the trouble of finding the routers mac address and all that, it should just show up?I could switch back to windows to see if I can connect, but I'm almost positive it's just the linux wireless manager..

I arrived in the Central African Republic only to find that my wireless (on an HP Mini 5102) wasn't working -- it didn't detect any wireless networks. So I wiped off Windows and installed Ubuntu 10.10, Luckily, it did! (Partly.) At first, I still didn't get any wireless networks. I messed around with all the various things you have to do to get Broadcom wireless drivers working. Finally, following a forum suggestion, I installed Wicd -- and this did the trick. Not knowing any better, I kept Network Manager alongside Wicd, but Wicd is what works much better. (Is there a reason to un-install Network Manager?)
However, when I try to connect wirelessly to the network at this country's one cafe with wifi (which usually works really well, by CAR standards), the network doesn't appear. At the office, when I open Wicd, it includes a box with the message "<connection name>: obtaining IP address", and bit by bit it connects. But when I open Wicd at the cafe, this doesn't happen -- it just gives me a list of random signals from nearby offices (all secured and low-signal), none of which I can connect to. Any ideas how I could get the cafe network to show up?I'm at the office now, and so it's working. However, in order to get it working I had to restart three times -- Wicd only seems to work about half or 33% of the time. Sometimes I get the message: "Connection failed: unable to get IP address" and sometimes I get the message "No wireless networks detected." Then I try again and eventually it works. So far.

First time ever switching from windows. Mainly doing this cause I though it would be fun to learn a new OS and see how it is.From watching a few videos it looked like all I have to do is click on the wifi logo at the top of the screen and I would get my router and a bunch of others (does this on windows) but when I click on it I dont get anything. I think it might be that im running this on a laptop. My wifi card is: Standard Dell Wireless 1501 802.11 g/nIts a new dell inspiron 5000 laptop i customized a little with more ram and a new video card.
Im guessing I will need to provide more info but as I said at the start Im new to this and not sure how or what info I would need to provide. Please just tell me how I can get any data you need and il get right on it. (I used Wubi to install this, went off without a hitch)
