General :: Use Ralink RT2501 / RT2573 As WiFi Access Point In Debian
Jan 4, 2011
I have a fit-PC server with Debian GNU/Linux (Lenny). I would like to use it as a wifi access point since my Linksys WRT54GS has become unstable.I have a USB Ralink wifi NIC. When I insert the card to USB I can see this with lsusb: Bus 001 Device 002: ID 148f:2573 Ralink Technology, Corp. RT2501/RT2573 Wireless Adapter.I have tried following various HOWTOs on using wifi card as AP in Linux, however, it seems that the card cannot go into monitor mode. I believe this is because I must use a newer driver or upload non-free firmware or something like that.I have tried installed wicd, but it does not help.
I bought this wifi adapter because I was told that it is one of the most common used Linux supported wifi cards that can be used as access point and a lot of other stuff.How do I set up this USB wifi card as wireless access point in Debian Lenny?

I've just installed Debian Wheezy on my old Toshiba Satellite A10 (Intel celeron 2.20 GHz, 1GB Ram, 30 GB hard drive) and tried to connect to my home wifi network with a usb wifi adapter (Hamlet HNWU254G). lsusb in terminal says it is Ralink RT2501. Ethernet worked fine, so I installed firmware-ralink package, the adapter was recognized and I was able to connect.
However, I heard quite frequently a strange whistle and realized it came from the usb wifi adapter; it also got very very hot. Other strange thing: the computer some times freezes: screen flickering, loss of control of mouse and keyboard, need to shut down with power button.
At first I thought it was the video card not being powerful enough for Gnome (even classic), but then I installed Xfce4 and nothing changed. Instead, when working offline, freezes happen less frequently (but still happen).
I've tried the usb adapter on another laptop with wheezy: it gets hot, but there are no whistles and freezes.

First time poster, some time Linux user. I've been reading and trying to create a wifi access point on my debian server. that is {intenet-router} <-> {server + usb-wifi} <-> {network users}
I've opted for this configuration as the server will become a firewall, traffic monitoring (sick of my windows machine getting hacked). I've spent a lot of time and I don't seem to have any un-clicked links in google left. I've read quite a few howtos and threads on this site and others ... I'm definitely missing something. Running: Debian Lenny (no gui)
[Code]...
I've also installed hostapd, and attempted a few things in there. Long run I want to allow wifi users to access the net. But will probably need iptables etc but just want to pass this step. I've see a few howtos seem to use ath0. It's probably only a minor issues.

Even with both machines in the same room, I'm only getting 1Mbps when using a pair of TL-WN321G wireless USB adapters to link my main box and my laptop. I'm using Fedora 11 on both machines. It is just as bad if I use the laptop's built-in wireless. lsusb shows the adapter uses the Ralink RT2501USB chipset. iwlist wlan0 rate gives "wlan0 unknown bit-rate information."

I use Ubuntu 9.04 and try to get a Sweex LW053 USB wireless card (Ralink RT73/RT2500 chipset) to work. According to the Wiki list in the sticky thread, this one should work "out of the box" since 8.04.
lsusb delivers
Bus 002 Device 002: ID 148f:2573 Ralink Technology Corp. RT2501USB Wireless Adapter
and there is also some wlan0 entry that doesn't look too dodgy when typing ifconfig.
From this I get that my laptop recognizes the card.
I also typed in some numbers such as SSID and DNS server address in Preferences>Network Connections where asked (although the information that I had wasn't 100% what was asked for so I tried to guess what needs to be filled in which fields).
However, I don't get an internet connection (Firefox can't find server...)
What else do I have to (or can I) do?

Whilst my office is decorated I have to move my computer. To make this as easy as possible I have setup my first ever wifi. An access point (wired to adsl router). It is working by using wicd and I am wireless at the moment. What security should I put in place (wicd says unsecured). I am probably quite safe as the nearest road or house is 200m away but I would like to learn what I need to do as this is the first time in over 20 years of computing that I have gone wireless.

Ubuntu 10.10 (kernel 2.6.35-23, amd64), Network Manager is installed, the laptop HP 6735s (I am certain that wifi is working, - I can connect to other wireless networks), connected to the Internet through ppp0 (VPN), eth0 looks at LAN interface, WiFi - eth1 (info from iwconfig).
WiFi driver "Broadcom 802.11 Linux STA wireless driverfor use with Broadcom's BCM4311-, BCM4312-, BCM4321-, andBCM4322-based hardware" is installed.
Objective - to create WiFi access point and connect through it to ppp0 with my phone (HTC Desire) or other devices.
My VPN connection (ppp0) and network are registered through my internet provider's script - [URL], not set up not by Network Manager. If I create a new wireless network in NM (point-to-point or access point, IPv4 set to auto) - laptop can not find the network, Internet immediately fall off. Through the manual settings and complex scripts that I found websites and forums I could not get it to work ..

I ought to understand the radio aspects of wifi better than I do. That said, is there a bad-good-best choice for wifi access point channel number? How does one select a channel number systematically (scientifically) rather than trial and error?

I just did a Wheezy reinstall (I just started using LVM on LUKS), but my Ralink RT5370 usb wireless adapter wouldn't work, even though I have firmware-ralink installed. When I click on the Network Manager icon, it lists my home network (WPA2 passphrase) as available, but clicking on it yields no result.
Before the system reinstall, I've been using the adapter with firmware-ralink without problems. As far as "apt-get update && apt-get upgrade" goes, my system is up-to-date.
I tried uninstalling and then reinstalling firmware-ralink (rebooted too), but to no avail. The adapter seems to be undamaged.
Here are a few pieces of info that might be useful:
Code: Select all$ uname -a
Linux watershed 3.2.0-4-amd64 #1 SMP Debian 3.2.60-1+deb7u1 x86_64 GNU/Linux
Code: Select all# lsusb

i keep reading about hostapd but i never figured out how to get the daemon working properly, heck i haven't figured out how to get the ethernet card ti bridge to the wlan card through command line
ps the wireless interface i want to set up as an access point is an SMC usb card that uses the zd1211rw firmware, i checked and it supports AP mode.i was told that you don't have to put the card into master mode all you have to do is configure the hostapd.conf daemon correctly and start the daemon, it will automatically brodcast an ap without an further configurations.

So theres this project I'm going to try working on during my free time and part of it includes using a wireless NIC as an access point. The way I see it, if a wireless NIC can send and receive wireless signals to a wireless router/WAP, why can't it be treated like one as a router/WAP? A router is a specialized computer after all.From what I heard this idea is possible but I'm having trouble finding results, since search engines don't know exactly what I'm talking about. Does anybody have any idea how I can accomplish this?

My wireless is 'almost' working, but frustratingly not quite there. Debian Testing (squeeze). I have two different wireless adapters. Both work flawlessly from an ubuntu live CD in the same machine, connecting to the same unencrypted access point so the problem is not faulty hardware, weak signal, overpowering signal, interference from other AP's, MAC filtering, or anything to do with WPA.
I have loaded the correct (I think) firmware packages for both adapters. dmesg is not complaining about missing or incompatible firmware. I have googled the various error messages reported in dmesg and found that the /etc/Wireless/RT2860STA/RT2860STA.dat missing config file is normal. I could not find anything that I understood concerning the BSS returned, data->length messages but since I see the same thing in Ubuntu (where the wireless is working flawlessly) I assume they are also normal and not related to the problem.
Both adapters can see all the available access points (using iwlist {iface} scan or using gui tools such as wicd, wifi-radar) NEITHER adapter will associate with any access point (and I've tried three different unencrypted AP's so far). I can connect to all/any of these AP's from an ubuntu live CD using the exact same hardware, so this is NOTHING to do with MAC filtering, etc... using 'iwconfig {iface} essid' as root to set the essid "appears" to work, but simple does not set the ESSID on either wireless adapter.
Using the GUI tools (which are only a front end for the command line tools so I have no idea why everyone thinks a GUI front end like wicd will magically work where the command line tools don't!!) I simply wait a long time for "getting network address" before it eventually fails. LOTS of information in pastebin, please make the effort to read it before asking me for things I have already supplied. And please keep any "RTFM noob" or "go back to ubuntu" replies to yourself. I HAVE read the f*cking documentation and I do not want to go back to ubuntu. I just want to get my wireless working in debian.

I have new emachine 1401 and I can't get it to connect to wireless. It does detect networks but when connecting keeps asking for password over and over and never connects. I don't have wired connection at all and the wifi router is not managed by me, so I'm retyping output through my windows xp samsung netbook which works over the same wireless network...
I have tries some other solutions I found around here (install bcmwl-kernel-source, rt3090-dkms_2.4.0.4, blacklist rt2800pci...) so it's not original configuration but behaves exactly the same.

I just purchased a RALINK WIRELESS G PCMCIA WIFI CARD VISTA/LINUX (UBUNTU).
It is supposed to be UBUNTU plug and play out of the box with no driver downloads needed.
I installed it but could not find a way to search the active Wi-Fi networks available like on my Actiontec card on windows xp. The wireless router/ethernet I have is an Actiontec setup for Qwest-DSL and Actiontec is the name of the wireless network.
Strangely I tried to choose setup a "new network" and entered Actiontec as the network name and it found the network and said it was connected to it. However the internet still is not working?

After having my usb wifi adapters working fine for some time, they stopped working and I can not get network connectivity.
Some one else was using my box and they reported seeing a kernel panic and then rebooted the box. Now there is no connectivity through the wifi interfaces.
I have seen the kernel panics related to this driver before, but usually a reboot has no ill effect.
Code:
root@Algalon:~# iwconfig wlan0
wlan0 RTxx70 Wireless ESSID:"a800" Nickname:"RT3070STA"
Mode:Managed Frequency=2.412 GHz Access Point: 00:0B:86:9A:08:80
Bit Rate=54 Mb/s

I have done the follow steps.
sudo ifconfig wlan0 up
sudo iwlist wlan0 scan (I see my access point without problem)
then...
sudo iwconfig wlan0 essid MY_ESSID key s:MY_PASSWORD
I get the follow error:
Error for wireless request "Set
Encode" (8B2A) :
SET failed on device wlan0 ; Invalid argument.
I used s: because I want to pass and ASCII password.

Im a Linux newbie and am running OpenSuse 11.3 (Gnome, 2.6.34.7-0.5-desktop Kernel) and Ive an Asus N13 wifi dongle (linux compatible). I currently connect using my laptopś internal wifi but I bought the dongle due to trouble with weak signal. It came with some sort of code that can be "compiled" but I havent got a clue how to do that (and I have been researching this matter for quite some time now). I then came across a post where someone with the same USB stick created and added only two small files to his filesystem and it worked...for him (maybe becasuse he was on a different Distro )
Ralink RT2870 USB Stick and created the two files mentioned in the post (network_drivers.rules and network_drivers.conf) and placed them in ETC... etc, etc! I rebooted the system but NetworkManager only lists it as "device not ready" ... So now back to square one.

I have an HP DV6 3143se which has a Ralink 3090 wifi card in it.the only thing that doesn't work at the moment is the Wifi. I tried installing the Linux backports module, but the trouble is that sometimes, my home wifi network is shown on the list of available networks and most often, it's not. when the network does show up, and i click on it and enter my WPA2 password, it takes ages to handshake and then it tells me that my password is wrong. the same password works in windows 7 so something's not working.
when i try to disable and re enable wireless network on the network manager applet, i get a Wireless device not ready or Network manager not running message.

I have a complicated situation due to my goals and network structure. I have in mind a potential solution, a bridge, but I do not know whether it is feasible or what hardware it will require.
The network:
My apartment community provides residents with free Internet access through an ancient T1 line. We do not have the option of other Internet providers, so having a router and modem in the home are not an option. The T1 line is split among some 24 switches, one for each building, and each switch has one port per floor. At each floor, there is a D-link WAP, and each has a separate SSID and WEP key. Additionally, they control access at the switch level using Access Control.
My goals:
I'm used to being in control of my networked environment. I like to have friends over often, and most of them have a laptop, a smart phone, or both, which makes Access Control a pain. I don't want to have to think ahead and get their MAC addresses to the IT consultant while he's here during business hours. My wife and I have 6 devices, two of which require an Ethernet connection.
I use a few applications for streaming that utilize UDP (I'm not sure if the WAPs are smart enough to even handle this) and I don't like having my traffic muddled with my neighbors.
I should note that I tried extending the network with my Airport Extreme router, which apparently only works with other Apple devices. I've also looked into WDS, but that seems to require an unlikely amount of cooperation from the IT consultant on site.
The potential solution: a Linux server that acts as a router. Ideally, it could act as a webserver for a small static site as well, but let's focus on the routing. I'd like to bridge two NICs and use masquerading (Internet Connection Sharing). The public interface would connect to the WAP using WEP. The private interface would allow up to 8 devices to connect to the server.
It seems easy enough to configure the public interface, and even to bridge the connections. What I've never done before is purchase a wireless card that can accept multiple clients. Maybe they can all do this?

I'm using some software that using mount point such as truecrypt. I also mount shared folder on other machine (fileserver) and publish it using ftp. The problem is when the truecrypt volume dismounted or the shared folder mount point loosing connection to the fileserver, user can write to the mount point without knowing that they actually not writing to the truecrypt volume or to the shared folder.
My question is, when sometime the server reboot and truecrypt volume is not mounted yet, how to prevent write to the mount point? I dont run truecrypt mount automatically for security reason.Some question for shared folder, if fileserver restart and the shared folder mount point got disconnected, how to prevent write to the mount point?

I recently bought a HP g62x laptop for myself. It sports a decent Core i3 processor, 4 gigs of RAM and a 500GB HDD. It also came with Wireless-N, a real bonus because I am using a Wireless-N router. The chipset is a Ralink 5390. It came preinstalled with Windows 7, and everything works fine in there (obviously).
I then proceeded to install Ubuntu 10.10 x64 a few days ago (this is before Natty came out) and everything worked . . . except WLAN. So I plugged in via Ethernet and went looking and found that I clearly wasn't the first to discover this issue. I found a guide here that I followed to download the Ralink Linux driver (which is stated to support my chipset), configure, compile, and install. Everything went perfectly, I restarted; lo and behold, I have a list of access points. I went to connect to mine, entered the password, and now the animated "WiFi wave" logo keeps going indefinitely until you click it, and it freezes for a few minutes. It will unfreeze if you let it sit but clicking it causes the same freeze again.
I couldn't really care less about a WiFi icon freezing, but a.) it freezes everything else in the system up, not just the icon, and b.) it never actually completes the WiFi connection. I really, really don't want to be forced to use Windows because of a crappy WiFi driver!
Since Natty came out I installed that and I can't even compile the driver without fatal errors, so I reverted to 10.10 and everything is the same as it was before. Note that this is a clean Ubuntu 10.10 Desktop Edition 64-bit install, nothing updated/modified/changed besides (attempting) to install this driver.

If I have only 1 physical WLAN interface, is there some hackery that can be done so that it can be a client of an existing access point and at the same time also act as an access point for other clients? I have an existing 802.11g ADSL router, and I'm going to be building an HTPC which will have 802.11n. My laptop also has 802.11n, but at the moment it only connects at 54Mbps because thats what the AP supports. I'd like to be able to have the HTPC be a client of my ADSL router, but have my laptop be a client of the HTPC, so copying files to it will be faster.

I am dual booting with windows xp on a dell computer I recently acquired. I am running Ubuntu 10.10. The computer didn't have a wireless connection so I installed a wireless pci adapter from a company called ZONET. I installed it perfectly on windows xp, however, I cannot install the driver and the "Ralink Wireless LAN" on Ubuntu. I inserted the cd, and opened the setup.exe file with Wine Windows Program Loader (I have installed Wine 1.3 by following the instructions on http://www.winehq.org/download/deb and clicking on the link that says "click here".
I am currently temporarily connected to the internet by borrowing my main computers ethernet cable). I followed the instructions on the InstallShield Wizard only to have two windows pop up saying there is an error (see attached image).
