Why? I have the channel selected manually, but I DO have adaptive Channel on (11, 7) Without that I won't get the full benefit of my srx400 laptop card. Why should I switch it off? Is it buggy? Where's the QoS setting? Do you mean in the TCPIP settings on my client PC? Or is it there in the admin pages somewhere? And why will turning it off help? Yep I do have a 2.4 GHz phone, but in times when my router isnt working, I turn that off (for days at a time) and it doesnt really help.
