Okay I will give this a shot when the house and the network here are quiet in case something goes haywire. If I do run into problems how do I execute a firmware default reset?

 

Also once the firmware is updated do I have to make any changes in the router settings or will the router save my info like my network names and the channels that I have the 2.4ghz and 5ghz networks on, etc?

 

Thanks again I really appreciate all the help:)

First step is to backup your configuration settings.  Add information to the file name so you can tell what firmware version was installed when the backup was saved.

If you have to update the firmware in more than one group of versions, you should save a configuration backup with each different version of firmware you install.   Simply best practice to avoid potential trouble.

A firmware default reset (factory reset) is accomplished using the recessed button on the back of your router.  Here are the details:  https://kb.netgear.com/9665/How-do-I-perform-a-factory-reset-on-my-NETGEAR-router

Your existing settings should come with you as you update the firmware.  Should is a key operative as you are jumping a number of firmware versions.

When you are updating this number of firmware versions, after the last one the recommendation would be to perform a firmware default reset and configure the router from scratch.  Save a backup configuration first.  Step through the user interface pages and take notes or save screen snips that indicate the section they came from.

Overall this is not a task for a few minutes time.  Your firmware is significantly out of date.
