Good luck!
The Network+ All-in-One Exam Guide was far and away the most detailed, yet friendly and useful resource I ever found for basic IT networking and Network+ prep. It's been years since I took the the exam, but the most current version of the book is here and my guess is it's just as good.
Professor Messer's videos are an obligatory recommendation for fundamental networking information and CompTIA prep.
I found these free ExamCompass practice quizzes to be a good way to identify areas I was weak in prior to taking the test. They aren't quite as in-depth as the test questions, but they are a decent review of concepts.
If you analyze traffic and configure routing for a living, a lot of the Network+ is likely going to be review for you, but a little review never hurts.
Depending on what type of higher paying position you're looking for, I might be able to suggest more certs/resources.
Best of luck.
The problem is that 008 just came out not too long ago, so all of the usual sources are still developing new materials. 007 hasn't been retired yet and has a boatload of materials, and a lot of the content creators are suggesting to take that instead (because it covers fewer things).
Anyway, Professor Messer has got about 4/5 of his videos out for 008 so far here: https://www.youtube.com/watch?v=As6g6IXcVa4&list=PLG49S3nxzAnlCJiCrOYuRYb6cne864a7G. I like his videos as ways to review stuff I've learned through a textbook. I'm using Meyer's All-in-One book to study for 007 right now, which has been decent, except that the chapters cover a little too much for my tastes. His 008 book doesn't come out until January: https://www.amazon.com/CompTIA-Network-Certification-N10-008-Comptia/dp/1264269056
