Netgear WNDR3700v2 - stuck on firmware 1.0.0.32? Need to downgrade to older firmare?

In my zeal to have the latest greatest router firmware for Netgear WNDR3700v2, 

I jumped to 1.0.0.32. However, I noticed that my Epson Workforce printer stopped 

connecting to the router, so no wireless printing for me. After some time now, 

my wireless network is not stable. Signal strength is awfully weak, and I started 

disconnecting form the router.

So the recourse was to upgrade the firmware. However, if you have 1.0.0.32 then
The instructions are pretty accurate, but they did not work for me.

1. I used a Mac.
2. Downloaded TFTP Client. It's a shareware, and it worked like a charm.
3. I had a difference router ip: 10.0.0.1 and a different password than the default 'password'. I think that was the issue for the posted instructions not to work.
4. I went to http://routerlogin.net/index.htm use admin and my password, then Maintenance, Backup Settings - Erase. Erase all the settings so now the router IP was 192.168.1.1 and username password: admin/password.
5. I then use TFTP server: No matter what I did, it won't allow me to upload any firmware. Searching for the issue, 

I found a few posts here and here. 

So these are the following differences:

Finally, the upload succeeded. Now I am back to v1.0.0.12.

Now its to be seen how it will fair! I will venture into other firmwares, but for now my wrestling with this router is at an end.

Thanks to the sources above.
