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?
I believe that V4 hardware is not supported by DD-WRT as of yet. Here is a compatibility table: http://www.linksysinfo.org/modules.php?name=Forums&file=viewtopic&t=4289 V4 hardware is not listed in the table as it is too new. Wilton
