My wife and I work from home and typically have a few other devices on at the same time (smartphones, smart tv, a few Alexa’s, etc.)

Our modem is 5 years old and router is 4 years old. I notice my zoom calls freezing for 3-5 seconds every 20-30 minutes when I’m on them, which is more problematic than you’d think. WiFi strength upstairs is weaker than downstairs. Internet seems just a little laggy/buggy at times. Would these two products be worth the purchase?
