Ralink RT5390

[bryce2]

So, I am brand new to Ubuntu, and have just installed Ubuntu 13.04. For some reason my wireless is half way working, It can detect routers and somewhat connect to them. But when I connect to my router and type in the password it will start connecting and then stop, and ask for the pw again. IT seems it won't let me connect.

my router has a WPA/WPA2 security, and my network controller is a : Ralink corp. RT5390 Wireless 802.11n 1T/1R PCIe

THanks in advance!

Have you tried it with no encryption/security set ? Temporarily disable encryption on the router and see if you can
connect. That way you can narrow it down to the WPA/WPA2 security.

Also, additional information would be nice. Please run the following commands in a terminal and post the output here.

lspci -nnk 
ifconfig wlan0
iwconfig wlan0

(of course, you should replace "wlan0" with your network adapter, though it should be working if you only have one wireless adapter installed)

Here is what code appeared in the terminal when i put in the above code


Usage: lspci [<switches>]

Basic display modes:
-mm Produce machine-readable output (single -m for an obsolete format)
-t Show bus tree

Display options:
-v Be verbose (-vv for very verbose)
-k Show kernel drivers handling each device
-x Show hex-dump of the standard part of the config space
-xxx Show hex-dump of the whole config space (dangerous; root only)
-xxxx Show hex-dump of the 4096-byte extended config space (root only)
-b Bus-centric view (addresses and IRQ's as seen by the bus)
-D Always show domain numbers

Resolving of device ID's to names:
-n Show numeric ID's
-nn Show both textual and numeric ID's (names & numbers)
-q Query the PCI ID database for unknown ID's via DNS
-qq As above, but re-query locally cached entries
-Q Query the PCI ID database for all ID's via DNS

Selection of devices:
-s [[[[<domain>]:]<bus>]:][<slot>][.[<func>]] Show only devices in selected slots
-d [<vendor>]:[<device>] Show only devices with specified ID's

Other options:
-i <file> Use specified ID database instead of /usr/share/misc/pci.ids.gz
-p <file> Look up kernel modules in a given file instead of default modules.pcimap
-M Enable `bus mapping' mode (dangerous; root only)

PCI access options:
-A <method> Use the specified PCI access method (see `-A help' for a list)
-O <par>=<val> Set PCI access parameter (see `-O help' for a list)
-G Enable PCI access debugging
-H <mode> Use direct hardware access (<mode> = 1 or 2)
-F <file> Read PCI configuration dump from a given file

I suspect that you copied the code I posted? Try enter each command separately, this should work. So first the "lspci -nnk" (without the "), then the other two.

[varunendra]

To keep the output short -

lspci -nnk | grep -iA2 net

You should copy-paste above to avoid typo. The pipe (|) symbol is on the same key as backslash (\) on my US-104 type keyboard.

And Welcome to the forums bryce2 !

PS:
While posting the output, please use 'Code' box. To see how to use it - please follow the "Using Code Tags" link in my signature. Thanks!

Thanks varunendra! Sorry, Like I said I am brand new to ubuntu and am a total noob lol. Ok, ill be sure to re enter the code seperatley instead of all together. Ill post back when i've finished!

[bryce2]

I have entered the code into terminal, this was the output:

05:00.0 Network controller [0280]: Ralink corp. RT5390 Wireless 802.11n 1T/1R PCIe [1814:5390]
    Subsystem: Ralink corp. Device [1814:f051]
    Kernel driver in use: rt2800pci
06:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8111/8168 PCI Express Gigabit Ethernet controller [10ec:8168] (rev 06)
    Subsystem: Hewlett-Packard Company Device [103c:2ab5]
    Kernel driver in use: r8169

[varunendra]

Let's try a few things available.

Please open a terminal and do -

sudo modprobe -rfv rt2800pci
sudo modprobe -v rt2800pci nohwcrypt=Y

Do not reboot after this since it is a temporary change and will be lost at next boot. If it helps, we can make it permanent.

If it doesn't help, then without rebooting, try saving your network's name (SSID) and security key in Network Manager settings. Also save your access-point/router's MAC address in the BSSID field of NM settings. Make sure "Available to all" checkbox is checked. Does this help connecting?

If not, please post the outputs of -

nm-tool
dmesg | grep rt2

[bryce2]

Ok I entered the first codes in seperatley and then tried connecting, same thing: it started to connect, asked me for the router password, then started connecting, then asked for the PW again.

The SSID, PW, and MAC addresses were already saved and "available to all" (Or in my case "All users may connect to this network") was also checked.

I entered nm-tool and this code came up:

In my case "CenturyLink8095" is my router. I also tried the other code dmsg | grep rt2, but when i entered it in the console nothing happened.
