On the flip side, I flashed my Buffalo WHR-G125 and have a few issues.
The first was my mistake. I did not do my homework. If I had, I would have known before I flashed that I cannot go back to factory firmware. I want to stress that this is not the case with every router.
My second issue is that since I recently flashed to the latest and greatest, my router reboots randomly. There is now a newer release out and the fix may be in it, I'm not sure. I believe I can flash back to the version I was using prior, and I would assume that my stability will return.
In my case, I did not need the extra features and I did not need the extra power. I wish I had stayed with factory firmware.
Just letting you know that it's not necessarily all a bed of roses.
