Hi,
I am having troubles when using ASUS WL-138G V2 Wireless LAN PCI Adapters.
I am using ad-hoc mode and kernel version 2.6.28.7. There is no rate
control for these cards. When I set the bit rate to auto, they always use 1
Mbps (they are very close to each other, around 1 meter). Also when two PCI
cards talk with each other, they do not support bit rates 48 and 54 Mbps.
The link quality for 36 Mbps is very good. When I ping from one to another,
most of the time, no packets can get through. Sometimes, I can get two ICMP
responses. They can use these rates for ACK frames when talking with an AP,
which means the modulation is there, but not works well for data packet?.
I also attached the output of dmesg and lspci below.
Thanks,
-Bo
