The non-psychics in your audience have no idea which version you had,
to which version (of what) you updated, or what "NetGear suggested".

"I"? Do _you_ have a wireless network connection, or are you talking
about some (unspecified) computer-like device? Define "fast" and
"slow". Generally, a 5GHz connection should be faster than a 2.4GHz
connection.

Sure, if you want. Otherwise, depending on what you did, you might
want to try installing some previous verion of the firmware, or
resetting and reconfiguring the router, or supplying some basic
information about what you're doing and what happens when you do it.
