Hi everybody, I have updated my WRT54GS v1.1 to HyperWRT 2.1b1 WRT54GS based on the official firmware 4.70.6. Everything works fine except that nothing happens when I tried to change transmission power (up and down) or when I tried to change the transmission speed (always 54 mbps according to Windows, 36 mbps according to Network stumbler). As this router is really working very well, I wonder if I am doing something wrong. For example, Am I suppose to activate something in order to have the changes accepted , etc ... ? I would really appreciate your helps. Regards. By the way, i tried a prior version of the modded firmware (based on 3.36.7 , I think). and it is exactly the same thing.
