Archer AX20 AX1800 Dual-Band Wi-Fi 6 Router

Been using Tplink AX20 since around Wifi 6 (ax) was kinda new, was around 18k back then & have served really well so far apart from rare occasional quirks. AX23 which is currently available in your budget is probably the same model with minor changes. Specs are good (quad core with enough ram) and dual band is definitely 100% 'not just marketing'. You get high link speed with wifi 6 devices. I get upto 1200Mbps link speed between wifi 6 PC & the router (depends on distance) and have played competitive multiplayer game on wifi with similar experience to Ethernet. If you ever end up transferring files over local network (between laptop & PC for example) you get good transfer speeds due to stable and higher link speeds. Large files can be transferred over network & there's also option to stream content over wifi within your local network. If you have an android tv box connected with wifi (or get one in future), it better be supporting 5Ghz for it to stream HD over wifi and a dual band router is needed in that case (when you don't wanna run an Ethernet cable) I have it connected to a line interactive sine wave UPS though, and probably that's the way to do it or you are just risking your router. It did survive Karachi heat so far. The more expensive AX50 version was known for overheating so I would still avoid AX53/AX55 unless they have fixed those issues. Also with tplink routers, for stability, it's a good thing to set them to auto reboot daily or at minimum weekly at some hour when no one is likely using internet.

Archer AX20. Rock solid.

The tp link archer AX 53 is currently on offer right now on Amazon and has max speed of 3000mbps so should be well enough for your usage or if you want to move further with virgin. The AX 18 should work too but for the extra 20 quid and with it being on offer may aswell go balls to the wall.

I've been using TP-Link Archer AX23 for about a year now. It's a WiFi 6 router and has been going great. I think I got it around 23-25k.

I use TP-Link EasyMesh without any issues. C6 v4, AX23 and AX53 in one mesh network. The AX53 is the master (also works as DHCP server), others are nodes. Works pretty well.

Archer ax23 is a perfect choice in your budget.

I feel that expensive routers as a whole are a waste of money. I have a 2.5G wired network with a NAS. Had a TP Link Archer AC1800 router. I'd typically hit 500-700 mbps transfer speeds. I tried a handful of more expensive routers from Asus, tp link and Netgear. They barely made a difference. I ended up settling on the tp link BE6500 dual band. Does all I need it to do, and is plenty fast.
