Ralink RT2500 Wireless problem: openSUSE 12.1 GNOME

ap1985 · August 26, 2012, 12:32am

Hello:

I researched everything that could be found on the forums and haven’t still been able to connect to my wi-fi.
When I check my routerlogin account, it shows my PC’s ip address under attached devices, which i think means that my PCI network card is communicating successfully with the router. It’s just that I can’t get internet via my wireless.
I also downloaded the firmware from this website.

After nothing seemed to work, I was reading this thread, post reply by nrickert, and made changes to “DHCLIENT” in “/etc/sysconfig/network/dhcp”. Still the wireless internet doesn’t work!

Is it something to do with the default firewall that the webpage do not load and gives this error?

Though, I was able to configure my LAN connection and the internet works fine if the ethernet cable is connected, just my wireless doesn’t want to work!

lspci output:

03:01.0 Network controller [0280]: Ralink corp. RT2500 802.11g [1814:0201] (rev 01)
    Subsystem: Linksys WMP54G 2.0 PCI Adapter [1737:0032]
    Kernel driver in use: rt2500pci

Thanks.

I get output for the ESSID of my AP and the MAC address as well as others (neighbors) in my surrounding, so the interface is receiving data.

My wireless network is WPA2 encrypted.

wpa_supplicantand wpa_supplicant-GUI both are installed.

/usr/sbin/iwconfig
outputs ESSID of my AP on the first line and MAC address next to the “AccessPoint” label (I verified this MAC address with the one from my routerlogin account. So I think this is not an issue.

/sbin/ifconfig
gives an output, which shows my ip addresses for eth0 (192.168.1.5) andwlan0 (192.168.1.3)

I have disabled my IPV6.

In general, you should never try to “interpret” the data. After all, you are the
one with the problem, and we are supposed to be the experts. In this case, it
does not matter - see below.

Same comment here!

And again.

Pinging an address on your computer shows noting. You need to ping the router,
which probably has the address of 192.168.1.1. In addition, it is not possible
to have both the wired and wireless interfaces both be active. As long as the
wired iface has a connection, it will be used as it is assumed to be faster.
Only when the wire is disconnected will the wireless be used.

Other than the problem with mixing wired and wireless, I think you have a
routing problem. Please disconnect the wire, make a wireless connection, and
post the output of ‘/sbin/route -n’.

Your router is NOT at 192.168.1.0. As ping pointed out, that is a broadcast
address.

Your routing table should look like


finger@larrylap:~/wireless-testing-new> route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
0.0.0.0         192.168.1.1     0.0.0.0         UG    0      0        0 wlan0
192.168.1.0     0.0.0.0         255.255.255.0   U     0      0        0 wlan0
finger@larrylap:~/wireless-testing-new>

It appears that you are not using NetworkManager. If not, then your wired
interface must be enabled “when plugged”, not “on boot”. With that fix, your
routing table will probably be set correctly; however, if it is not, then you
will need the command:


sudo /sbin/route add default gateway 192.168.1.1

That will add the line with the UG flags.

Thank you sir: Larry aka lwfinger
I changed my wireless card “Device Activation” to “On Hotplug” and executed the command that you posted. Now my wireless works!

Thank you for taking time to read and reply this thread. I really appreciate it!

Wireless should be “On Boot”. Wired should be “On Hotplug”. The command will
always work, but if you have the activation wrong, you will need that command on
every boot.
