    ASUS N13 w/Slow Connect Speeds?

    OK so I've read over a few threads on this but have found nothing to resolve it. This computer in question has both Windows XP x64 and Ubuntu 12.04.2 x64 on different hard drives along with an ASUS N13 USB wireless adapter. On the Windows XP OS I get connect speeds of 144 MBPS but in Ubuntu 12.04.2 it only connects at 57 MBPS? Kudos to the developers for getting Ubuntu to see the card and automatically configure it but it's way slow at file transfer so I need to get it's connect speed up to at least what Win XP will do. The router is only good for 150 MBPS wireless so with Windows doing 144 KBPS I figured that was pretty good.

    Here is the output from lsmod that shows this wireless network adapter with an rt2800 chipset. Most of the info I see on these states that most of these have a rt8169 chipset but few people seem to complain about actual throughput speeds??

    Code:
    parport_pc             32867  0 
    rt2800usb              22903  0 
    rt2800lib              59396  1 rt2800usb
    crc_ccitt              12708  1 rt2800lib
    rt2x00usb              20809  1 rt2800usb
    rt2x00lib              55575  3 rt2800usb,rt2800lib,rt2x00usb
    mac80211              555272  3 rt2800lib,rt2x00usb,rt2x00lib
    cfg80211              208382  2 rt2x00lib,mac80211
    parport                46563  3 parport_pc,ppdev,lp
    So can someone tell me how to make this N13 adapter connect as fast in Ubuntu as it does in Windows XP? Lightning has fried two 1GB wired network cards on this computer so I'd rather not buy another one as sooner or later it's going to fry more than just the network card.

    Thanks

    Thanks for your reply. Here is that info in the order you wrote in your post.

    Code:

    The Second one seems to be a bad command?

    OK tried this but it's still running about half the speed of Windows XP? I moved a 775MB movie file from my desktop to my Wife's new Dell Laptop across the wireless Draft N router and it took just over 5 minutes using Windows. Using Ubuntu it took over 9 minutes? Any other suggestions?

    Thanks,

    Re: ASUS N13 w/Slow Connect Speeds?

    I've been having problems, using a USB-N13 as well. As far as I can tell, there is a kernel bug in kernel 3.8. The only way I can get the damned thing to work at all is to downgrade to an old kernel - works fine in kernel 3.5.

    Is there any news on a fix to this bug yet? There are several threads lurking about complaining about this specific brand of wifi adaptor. The problem is that the kernel driver is broken. How long before an Ubuntu or Linux kernel developer pushes a fix to the repos?
