Alpha ring, wifi slowness comparing to public release

You are in a build that is in the Windows Insider Slow ring. This is a beta build not yet released to the public.

If your friend is in the Xbox Insider Program, it might be that the Guide re-arrangement feature is currently in testing for the Alpha and Alpha Skip-Ahead rings. He could start the Xbox Insider App and check which ring he is enrolled in.

If he's eligible, he might have the chance to move up to an Alpha ring, but also at the risk of new stuff not working. So he should really consider if it's worth moving up to a less stable ring.

When that new feature is being released to lower rings or the general public depends on how many issues the Alpha Testers find with the feature.

Only if it's considered to run stable, it'll be released to lower rings or for general availability.

Your friend is incorrect.

The feature is being tested by people in the Alpha rings of the xbox insider program but has not been released to the general public yet so you still need gold to play games like Fortnite for the time being.

This has supposedly been fixed, along with a bunch of other stuff, in an update that's available for people in the preview program (alpha ring) now.

So, if you're in the alpha ring, check for updates and you should see it there ready to install.

If you're not in the alpha ring, or you're not in the preview program at all, I expect they'll roll out an update with a bunch of fixes in it to the public fairly soon.

The new update is only out for some Alpha & Alpha skip ahead insiders at the moment.

If you're in the Omega ring then you'll probably be the last ring to get the update before it's released to everyone.
