Before you trash it try this. There is a 3rd party firmware that will allow you to drop your firmware to less than 1.21 but first you must drop your current fw to 1.21. Then go to ispgeeks and get the downgrade file and reflash your router to 1.15. Once you're up on the 1.15 you can flash it to 1.16b3 which was the best fw that I used. I ran it on the a2 d-link sent me to replace the a1 that was hosed by the 1.21na fw. I'm gonna dig that old a1 out of the box once I find it and downgrade the fw on it since my a2 died this week. Once I reflash it I'm gonna keep it in reserve. Just dropped some cash on a netgear wndr4500 to replace the a2. I have both files if you need them and if you do just pm me.
