WNDR3400v3 is very slow with firmware v 1.0.1.4_1.0.52

I recently updated the firmware in my WNDR3400v3.  The version now installed is 1.0.1.4_1.0.52.  All connections, wired and wireless, are very slow with this new firmware.  My internet provider indicated that Netgear firmware has a problem and has released a beta version to fix the speed issues.  How do I either go back to the old version of firmware or obtain the beta version?

I did the factory reset after submitting the question, it seems to have helped.  I am monitoring it for a few days to see if things are improved.

Welcome to the community, @tpsynd

Did you factory reset the router after firmware upgrade?

After factory reset, reconfigure the settings and verify your speed. 

To downgrade the firmware, you download the previous firmware from this site and follow the instructions below on how upload it. 

How do I manually upgrade firmware to my NETGEAR router?
