My wifi seems to be very slow on Fedora 17 64-bit (Ubuntu as well). I have a 512kbps connection (which is already quite slow) but it takes forever for webpages to load. In many cases it isn't able to open websites at all. Chrome, for example, says Resolving Host and then gives up.
I use a wifi dongle and it seems to work out of the box. It's a DLink DWA-125 which uses the Ralink RT3070 chip. Here is the output of lsusb:
Bus 001 Device 002: ID 07d1:3c16 D-Link System DWA-125 Wireless N 150 Adapter(rev.A2) [Ralink RT3070]
The card is supported by the kernel so I haven't installed any third party drivers. Could someone please suggest how I could fix my problem?
I read a post which said blacklisting modules which aren't required will help. lsmod |grep rt gives me the following. Is there something here which I must disable?
rt2800usb 26758 0
rt2x00usb 19758 1 rt2800usb
rt2800lib 60984 1 rt2800usb
rt2x00lib 66508 3 rt2x00usb,rt2800lib,rt2800usb
mac80211 554733 3 rt2x00lib,rt2x00usb,rt2800lib
cfg80211 197072 2 mac80211,rt2x00lib
crc_ccitt 12614 1 rt2800lib
The devices page wireless.kernel.org says that the corresponding module for my dongle is rt2800usb.
Thanks in advance!
PS. I was running a yum update while typing out this post. In the beginning I had very bad speeds and the downloads would fail (I got the Trying other mirror message several times). But now I'm getting a good speed of 60+kBps which is close enough to my max network speed. yum isn't able to connect to Google's servers to update chrome however.
