Westell - 7501 Wireless-G Broadband Router

Edit: to clarify. I posted what I've used in the past, not what I want to use next. The first two were recycled. I added an image of what I've used over the years (Linksys WRT54G, Westell 7501, Asus AC-1900). I feel like the 3 primary routers I've used have been great and reliable. I think I got lucky. I'm looking for a moderate upgrade, even though I don't really need it. My current Asus is pushing 10 years and I'd like to retire it and keep it as a backup. My wishlist: ~$75 (I can wait for a sale), super reliable and automatic, dependable, WiFi6 or 7 just to keep up, would work well with older WiFi tech. A mesh system is not required, but my parents have a 2story house so it might help. I've got the ability for wired back-haul. Honestly a single point would be fine for us i think I want this for my family, my parents, and my grandparents. None of us are power users. All 3 of us have the same AC-1900 router, which makes management super easy for me. In-fact, besides powering off and on occasionally, they've been very reliable for the non-tech-saavy. Just looking for something to continue that tradition. Last year, I bought an ASUS AX3000 WiFi 6 Router, but I returned it. I used it for ~3 weeks, but it was super unreliable compared to my current Asus AC-1900. I never figured out why. I thought it would be an upgrade, but it seemed slower and had tons of connection issues. I have some older tech that was the primary connection problem, but even newer ~4 year old tech was having trouble. Maybe i screwed up the configuration, but it was also more complicated than my current Asus. Hoping to avoid that again. Need something the other family members can handle without any input, like we currently have. Thank you!
