MyNet n900 old firmwares because if instability

Hello I am like everyone else who is having problems with their new n900 router. Instability and loosing Internet plus sometimes just disappearing off the network.
I was wondering if people have been having better success with other firmwares. Other threads have been suggesting this.
I have been unsuccessful trying to get the other firmwares can any other users host them if possible. When I type the full address and file name I get nothing.
Any help would be great as this router was supposed to be one of the best.

From the second perma-sticked thread at the top of these formes is a link to the older firmware straight from WD about 1/2 down the page from me.
