Wireless much better on Windows XP

English Network/Internet

I am in a similar position to View Profile: jadaml - openSUSE Forums in his post/thread here:
Unusually slow Wireless

ie, from windows I get significantly and consistently better speeds.

Would the kernel update improve things for me?

I use a USB wireless adapter (a hawking dish):

Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 002: ID 062a:0000 Creative Labs Optical mouse

I use ifup from YAST to control the settings.

The method that you use to control the device makes no difference once the
connection is up.

The zd1211rw devices are obsolete and that driver gets little attention. If you
want to improve the throughput, get the kernel source and fix it. Otherwise your
only alternative is to use the Windows driver with ndiswrapper, but that will
likely not work if your Linux system is 64 bit. In addition, you run the risk of
system crashes with Windows code allowed to run in kernel mode.

Just a bit curious:

Because the trying to rebuild the driver as open source on
zd1211rw - Linux Wireless

…]
Performance

* RX performance is about half that of vendor driver, will be improved (probably better now, needs re-measure)
* TX speed should be OK, can be optimized to remove memory allocations in critical path

…]

and
Supported Zydas ZD1211 devices - Linux Wireless
and
RFtypes - Linux Wireless
was not promoted by the vendor?

Would it be possible (or possibly worth the trying)
to use the driver from
SourceForge.net: ZD1211 USB WLAN Linux Driver - Develop
?
