On an established Unifi AP network with 4 access points, a problem just occured where all wireless clients are not receiving a DHCP address, and therefore no internet access. All wired clients are working fine. Have restarted all AP's. DHCP is provided by MIcrosoft SBS. If I set a wireless client to a static IP address, I still cannot access the internet or ping the wireless client from a wired client. All four AP's are exhibiting the same behavior. Thanks for any help.

Our outside IT vendor (who sells and installs Ubiquiti products) came in yesterday and tried a few things. He could not find any real issues. We installed the DHCP server on anither VM, which didn't help. So we purchased and installed four new UAP-AC-LR access points, which solved the issue. So we really never found the issue, but it is resolved.

When you connect wirelessly with a static IP, how far can you ping/tracert through? Ping all the APs? Ping the controller? Default gateway? Ping internet via IP address (not FQDN to eliminate DNS)?

I found two devices which can connect DHCP (see connection list) wirelessly with no problem. After upgrading firmware in AP's, I was able to set a laptop and an iPhone to a static IP address and regain full connectivity. But if I change them back to DHCP, connectivity is lost.

Welcome to the community!
Tried restarting the DHCP server?

@RobbieH yes, I can ping the DHCP server. Weird, huh? And a couple of wireless devices are working fine. But several desktops, laptops and printers on DHCP are not. Also, not a single mobile device will connect - Apple or Google phone.

You know what, I've seen some issues reported with Android in general and iOS 12 on Apple. I don't see those issues on my network, but some others have reported success from changing their DTIM period to 5.
