Orbi RBR50 and Slow WiFi Problems with iOS Devices
I’ve been experience a very strange problem with slow WiFi speeds on my iOS devices for a few months now and was wondering if anyone might be able to point me to something to try to fix it. It se...
In the advanced wireless settings of orbi try unchecking the box that says Enable 20/40 MHz Coexistence I know this has improved performance for some IOS devices.

DarrenmM, thanks for getting back to me!
For some reason or another, after a recent reboot, things seem to be working normally again. This is after three months or so of issues. At any rate, one thing that appears to have eliminated the Internet access stalls is I made a change to my DNS servers. I previously had a Mac Mini server as primary DNS server and my NAS server as secondary. Switching these seems to have resolved the stalls. I haven’t had time yet to troubleshoot the Mac Mini, but will see if I can find a problem with the DNS server app on it.
So, for now, I’m kind of waiting for the other shoe to drop and the access speed slowdown issue to occur again. Hopefully it won’t, but since I haven’t changed anything that should have impacted it, I’m thinking it will rear it’s ugly head again at some point.
Well, as expected the issue has reared its ugly head again. Tonight when I got home from work, my iPhone immediately showed symptoms of low access speeds and stalls. My iPad was fine for a few minutes, but then it, too, did the same thing. No amount of monkeying with either device would get them to work properly, but my MacBooks and PCs were all working just fine.
I eventually rebooted the router and the iOS devices started working again normally.
Does anyone else have any ideas what might be going on?
I am running the latest firmware on the Orbi, 2.1.2.18 and the latest version of iOS, 11.2.5.
If DNS was your issue before, try disabling your personal DNS servers temporarily and using Google's DNS or your ISP DNS servers and see if that resolves the problem. If it does, then you would know the issue is something with your DNS servers.
Thanks for the suggestion. I actually went through and tested several DNS configurations using Namebench and it turned out that my Mac mini server was 7 times faster than any of the other options, so I once again promoted it to primary and it has worked as expected ever since.
I’m just counting down the days until I next need to reboot the Orbi router to keep all the iOS devices happy.
