The router I currently have is one of the netduma R1 from a few years ago and while the software side is brilliant the WiFi has started to wane and results in a couple of drops a week. Also while we don't have issues with signal when my sister stays and use iPhones they do, they connect but have little to no bandwidth so just use 4g. This is at less than 10 metres away but in a different room so not far at all.
I have fibre at 80mbps/20mbps and no one is a heavy user really, there's minimal streaming one in a while.
Last year I bought an EAP225 in the aim of better WiFi but saw no difference. I think the times come to replace the router. It's used for general Web browsing on mobiles and tablets, minimal streaming to chromecast and gaming.
Gaming is the big one, I know gaming routers aren't a thing as such but I have heard routers with openwrt are better for gaming traffic speed.
So what router would you recommend with strong WiFi signal and would you recommend third party software over first party? My budget is less than £80.
