RT3090 slow rx

Hey guys, this is my first post in here, I'm from Chile, so please excuse my english

Well, this is the problem, I've a new laptop, a Lenovo z475 one. And it has a Ralink wireless card (it sucks btw).
For default, my arch (3.4.2-2-ARCH) has a rt2800pci module load. I tried a lot of guides, and the most of them fixed this problem by downloading the RT3090 module (From AUR or the manufactured support page). On the guides they say to blacklist the rt2800pci rt2800usb modules and dependencies. I do that but RT3090 gives me a Kernel Panic error.

Also I've tried another guide who says that the module rt2860pci works fine with this issue, but when i load the module, the module don't recognize the interface now i'm using the Rt2800, works, but a little bad.

Ty and let me know if you guys need more information.
Thx to all.

Re: RT3090 slow rx

Hi and welcome to the forum. Your post title does not match your text (or is sarcastic about slow ..) , be sure to correct that.

Also post the device ID of your card here (lspci -nn line) as that is what usually determines which driver to use.
But I reckon RT2800pci is the standard driver your card is supposed to use.

Whats your actual problem? Is it just slow? Or does the connection drop?
Have you looked at the logs? Any hints there? Router Signal is strong enough?
Any other wireless modules loaded that might interfere?

Re: RT3090 slow rx

Oh dude, thx for the answer..

Output of lspci: 02:00.0 Network controller [0280]: Ralink corp. RT3090 Wireless 802.11n 1T/1R PCIe [1814:3090]
@The internet goes so slow, and the signal is at 95%. When i tried RT3090 that marks my actually 30mb/s download (but it get kernel panic in a few seconds), and with rt2800pci the download speed is about 0.7mb, The other modules loaded are dependencies of rt2800

lsmod | grep rt output:

Re: RT3090 slow rx

Please always use [ code ] tags for longer console output next time, thanks. I don't see anything in there though.

RT3090 is deprecated unfortunately for you. I googled your card and I guess rt2800pci is the correct one to use. With that poor speed you should see some network errors though.

The only suggestion I have currently is that you do

modinfo rt2800pci

to look and try some of the available options. For example try to disable wifi-N.

Maybe someone else has another idea.

Re: RT3090 slow rx

Try disabling hardware encryption

modprobe rt2800pci nohwcrypt=1

Your upload speed and ping look good.

edit: typo in module

Re: RT3090 slow rx

did you make a config file in /etc/modprobe.d/ to set this value every time this module is loaded?
