Poor wifi speed from TL-WR840N router
Hi,
I have a FTTH connection which runs at 100Mbps . When I connect my laptop to my fibre router via an ethernet cable I get my full 100Mbps (in fact it goes at 200Mbps). I have bought the TL-WR840N wifi router which I have connected with the ethernet cable that came with it to my fiber ONT . I have connected my iphone xR to the wifi network and ran a speed test standing right next to the router and I am only getting between 50 and 65 Mbps . The router is advertised as 300Mbps over wifi so what is the problem? The signal also seems to degrade quite quickler the further I move away from the router.
Any suggestions ?
Thank you
Chris
