Only getting 5Mb/s in Ubuntu
 
Hi


My rt2500 network card works fine in Ubuntu live session but according to connection details I'm only getting 5Mb/s. My network card is 802.11G so I should be getting something like 56Mb/s, but how do I do that?

I haven't had to do anything to get it to work and it works fine with WPA, so I don't think there are any major driver problems, but I have heard of the unreliability of these linux drivers.

Please help.

Hey there linuxisgreat.

I'm glad to see I'm not the only one who had that problem with Ubuntu (before I got rid of my wireless card that is.) I had that same card, with the same problem, but I was only getting 1 MB/s. The only way I ever fixed it was to install NDISWrapper and use the Windows driver (which gave me full speed)...

Its not the problem with Ubuntu. I have seen this problem almost everywhere in India, from cyber cafes running windows to my office, running on Linux. Our LAN cards are capable of 10 MB/sec of speed but I never got more than 2.1 MB of transfer. Same for cyber cafe, you never get more than 80 KB/sec of transfer.

Hmm...that's really odd...and the 80 KB/s transfer rate is all you get when moving files across the local network too?

As I said, these days, in my office, I get 2.2 MB/sec, when it should be 10.

Hey now I'm now getting 2Mb/s too, that's even slower! This is really strange as I think I get the full 56Mb/s when I use windows with this card.


I can't check right now as windows has stopped working on my machine and I can't do what I need to do to fix it.


I haven't tried moving files across a network, I've just been using the internet with ubuntu.

hopefully duplex settings is set to autoneg and ipv6 if set to off if you are not using it.

Are you using NDISWrapper or the native Linux driver?

As an answer to your question read what I said in my first post above:

I didn't have to do anything to get the card to just work, I'm using ubuntu from live cd with the native rt2500usb driver.

Also I tried my network card in windows safe mode with networking and in status it said my network card was getting 56Mb/s.

If it's working in Windows like that, then it's as you said, the unreliability of the Linux driver...I had alot of bad luck with it on mine...so i had to switch to NDISWrapper and use the Windows driver...
