To negate any setting changes I may have made I upgraded the switch to the latest firmware version and did a factory reset.  The only change I made after that was to set the admin password.  I checked and the problem is still there.  It is not a Layer 1 or Layer 2 problem.  All populated port LED's are showing connections at the appropriate speed and activity.  Here is my network as it is:

ER605:

- Port 1 WAN Uplink to WAN Fiber Modem

- Port 2 VACANT

- Port 3 homeassistant

- Port 4 EAP110

- Port 5 Downlink to TL-SG108PE

SG108PE:

- POE Port 1  EAP225

- POE Ports 2-4 VACANT

- Port 5 Laptop

- Ports 6-7 VACANT

- Port 8 Uplink to ER605

1] All devices except for the laptop are working fine including Internet access. If I move the EAP110 to one of the Non-POE ports on the switch devices connected through it do not have internet access.

2]  I have tried the EAP225 on all 4 POE ports and it works fine on all 4; devices can access the Internet.

3] The laptop does not work on any port on the SG108, but does work when connected wirelessly through the EAP110 and EAP 225.

4] When plugged into the SG108 I cannot ping microsoft.com because there is no DNS resolution.  I can ping it by using its public IP address.  Also, local DNS inquiries resolve to IPV6 addresses, not to IPV4 addresses.

So it appears to be a Name Resolution problem for anything on the SG108PE except the EAP225 and devices connected through it.  

Any ideas on what may be causing the problem and how I may resolve it?
