I have tried installing the driver from the asus web site but I think it was the exactly same as I already had installed..
I did manage to get almost full speed (around 11mB/s) yesterday by disabling firewall on my router... this lasted for some time, but after some time it started coping files again at 3mB/s 😕 ...which leads me to think that the problem may be in the router, even tho I had many computers at home and none of them had any problem transfering files during almost 2 years I had this router (its from virgin media super hub which is some netgear cg3101d) ...this is the first issue with speed on local network.
