AC versus N Wifi internet performance issue

[ardent73]

So I was using ac wifi with no problem until last week the internet slowed to a crawl. I rebooted everything, poked and peeked, and nothing until I switched back to n and suddenly the internet is flying at warp speed again. Switched back to ac, the internet is a trickle, back on n it's a flood.

Has anyone else experienced this? Because I don't know what changed...

MacBook Pro is 4 feet from the Airport Extreme

Is your SSID's separated between 2.4 and 5 GHz networks?

Could be lots of different reasons. Maybe your neighbour is running interference?

If the MBP is only 4 feet away why not use an ethernet cable? Much faster and not subject to interference.

Yes.

No new Wifi in the neighborhood, but they could be hiding the SSID.

Don't have an ethernet port nor a usb adapter.

My advice:

Go with WHAT WORKS for you -- even if the seemingly "slower" setting actually works faster....

My best advice here is to try a factory reset and leave the networks under one SSID and give it a try. Then try separating them back out if you choose.
