    And Firefox doesn't connect to anything. It looks it up, and then goes into the "waiting for...." state.

    If I use ethernet, neither of those is a problem.

    I have the latest .24-18 kernel which is supposed to have this built in. But I have done all the blacklisting and installed rt73 per the directions. It works sufficiently to get connected and ping. The STATISTICS show a lot of data passing in both directions. That's why I thought they were two unrelated problems. But they disappear completely when I go to an ethernet connection.

    In fact, I can eliminate the wireless router as well. I'm connecting my ethernet cable to a Linksys bridge and it works fine. It looks like ethernet to the computer of course, but it is actually connecting to the same wireless AP.

    since you can ping, but not browse, and you have disabled ipv6 then you likely have a dns resolution issue.

    to fix this, try using opendns servers according to the following howto:

    Re: [SOLVED] RT2500 an absolute waste of time and effort - any better suggestions?

    Jack Rickard,

    I did some looking around and can't find anyone with similar problems as you, but there are some suspicious things about your situation. First, your interface is named wlan1. Where's wlan0? Second, I think that the serialmonkey drivers should name your device rausb*, not wlan*. So I think it might be the case that something strange is going on with the drivers; possibly they're interfering with each other.

    When you get a chance, please post the output of these commands so we'll have a better idea of what's going on:
    Code:
    iwconfig
    cat /etc/modprobe.d/ralink
    modprobe -l | grep rt2
    lsusb
    Please also run this command:
    Code:
    sudo -s
    echo 'blacklist rt2570' >> /etc/modprobe.d/blacklist
    exit
    to add rt2570 to the blacklist (I read about some people having conflicts between that driver and rt73. rt2570 shouldn't be installed unless you compiled it, but it can't hurt to blacklist it).

    Finally, have you done anything else on this system that could affect the Ralink drivers? Did you build any drivers besides rt73, like other serialmonkey ones or the ones from Ralink's website, or anything?

    If we can't figure it out from this, we can still always to the serialmonkey forums, but I hope we'll find a solution here.

    please see post number 21 above yours. i believe you're having a simple (and common) dns resolution problem. if the opendns servers do not fix your problem, please let me know.

    I don't think DNS is his problem. He seems to be able to resolve domain names using the 'host' command, and he gets the same faulty behavior in Firefox even if he enters IP addresses in place of domain names. I'm no expert on DNS, but based on these observations, it seems like DNS resolution is working correctly, isn't it?

    if ping works to external sites by both dns and ip, then it seems reasonable that the wireless drivers are working correctly. something else is wrong here.

    it's possible that using opendns will not fix the problem, but it's easy to try and won't hurt anything even if it doesn't work.

    i also highly suggest rebooting the router.

    Re: [SOLVED] RT2500 an absolute waste of time and effort - any better suggestions?

    Adding open DNS did nothing.


    /etc/modprobe.d/ralink is however interesting.

    alias wlan1 rt73
    alias ra0 rt2500



    I HAD previously compiled rt73. Now, I've compiled rt2500 as well????

    I had originally installed a D-Link USB wireless and it was assigned wlan0. When I replaced it with the Hawking Technologies WHUG1, it was assigned wlan1.

    I've never had an ra0.

    If I delete the first line of the ralink file, it cannot find ra0 or any wireless device.

    If I make clean and recompile and make install the rt2500 CVS, it tells me it is adding ra0 to the alias file. But I don't wind up with a device tied to it.

    Yes, I did compile the rt73 drivers from the serialmonkey post here on ubuntu forums. YOUR post in this thread seems to compile rt2500. Is this the same driver or different.

    iwconfig

    lo no wireless extensions

    eth0 no wireless extensions

    wlan1 RT73 WLAN ESSID:"Riverhouse"
    Mode:Managed Frequency=2.442 GHz Access Point: 00:1A:70:48:7F:E6

    Re: [SOLVED] RT2500 an absolute waste of time and effort - any better suggestions?

    sorry to hear that opendns did not help, but i still do not believe that your problem is ubuntu.

    try some simple things like checking ethernet cable connections (between router and modem). reboot your router (unplug the power, and plug it back in). do you have another computer with which you can test your wireless network? is there another wireless network that you can attempt to connect to?

    everything you've posted shows that you have a perfectly functional card. how is your network physically set up? what kind of equipment are you attached to?
