olvasása után.
Idézet a ChangeLog-ból:
Linux 2.6.18
zd1211rw added to mainline kernel
Firmware
Firmware is pulled from userspace, get the files here
The location the firmware has to be put to varies from distribution to distribution. See dmesg output if loading firmware fails.
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
Tehát szerezz be egy gyári firmware-t. Pl windows driverből kicsomagol stb.
Talán az segít.
