I have an Archer AX20 router, planning to purchase a mesh Wifi extender to plop one in my son's room, which is about.. 7, 8 meters away? With 2 PCs in it. I'm on Unifi 300mbps, currently looking at RE305, or is RE205 sufficient? Thanks guys!

I have an Archer AX20 on 500mbps connection, with about a dozen+ devices connected. Works just fine, no throttling whatsoever.. except when any of my sons download new games (games these days and their dozen gig sizes) from.. Steam or wherever, at certain point my router will reboot itself, which is almost certain to happen. They're both on Wifi, and my PC which is connected by ethernet, faces no such issue. Do I need.. a more robust router? Or cap the download speed on my kids pc? Or any settings I should take a look at..? Thanks guys!

I just replaced it with an AX72, no more issues after that(other than problems connecting to a TC60 camera). Than you for your reply!

Yes, just noticed it, thanks to you! Will see and experiment
