I’m dreading setting up (upgrading) my home network, I know I’ll have issues and making threads is slow and a pain. Where could I get some live help for one night?

My work depends on an internet connection, so when I begin I can’t really let it fail and have to successfully set it up that night.

Basically I have a Comcast modem, and I have an aftermarket Unify Access Point Pro router which I actually use for spitting out my WiFi signal, and have my modem WiFi signal disabled.

A colleague set it up for me and I don’t necessarily know how.

I got a new modem from Comcast and I’m ready to upgrade, but I imagine when I plug in the new one it will mess up my existing Unify access point stuff, that’s the part I know I’ll need help on. I’d kinda like to set up a whole new network which means hard resetting my Unify stuff, and now I have two of them I’d like to place somewhere. My colleague downloaded my network software, but the computer that had the admin system is gone and I forget the password now. So I’m guessing I basically need to hard reset and start everything from scratch but I’m not even remotely a network expert.

Making threads is slow, I’m sure I’ll run into questions. Is there some way I could find a network specialist who could answer my questions as I try to go through it? Where would I look?
