I’ve just had a lot of unexpected expenses lately, so looking to spend like $50 or less.

We have

• 200 mbps fiber internet (so it’s just straight ethernet feeding into the router)
• 2000 sq ft home with same size basement, (just wood in between, no concrete)
• very few wireless devices (like 2-3 most of the time)
• NOBODY GAMING ON WIFI, this is just for my dad to watch videos online with a laptop
• need to be able to limit bandwidth by device
• prefer to be able to flash custom firmware (ddwrt or openwrt or whatever) to make an older router more secure
• would like to block ads on router level (DNS blacklists and IP blacklists)
• need it to be stable and not frustrating and constantly dropping signal or something

Thank you!
