View Full Version : [ubuntu] Slow wifi on Marvel 88w8335 (b/g) based PCIMCIA card

Hi, I've got PCMCIA wifi card with Marvel 88w8335 chipset, and I use ndiswrapper to get it to work in Ubuntu. But when I connect to my wifi network (D-Link Di-524 b/g, wpa2 protected), the connection is very slow: about 100 kB/s, both upload and download. The download should be something about 12 Mb/s (which equals about 1.5 MB/s). Today I discovered that lshw -C Network shows my card as wireless=IEEE 802.11b, and it should be 802.11b/g

Could it be the reason why the speed is so low? How to change it?
