Just got a new WRT54G V4 with latest firmware. The whole purpose of getting it was for the QoS. The Linksys QoS does not cut it. I tried to load DD-WRT V22-r2 and get "Upgrade are Failed" error. I loaded the latest HYPER-WRT and since it is Linksys based the QoS has same problem. I tried again to install DD-WRT with same problem. While I'm not new to routers I have never had a Linksys. Something I'm doing wrong?
