Delayed login when Laptop connected on wireless network ( Stays in please wait screen for 5-6minutes and then logs in)
Hi
We have 90 Laptops using the Wi-Fi network and 200 PC connected to wired network and 3 domain controller the DHCP server is installed on the DC-1.
We have a delayed login problems only with the laptop connected to the wireless network. When I log in it takes 5-6 minutes to log in and load the desktop. And after it logs in if I do gpupdate / force it takes 5-6minutes to complete and comes with this error as attached.
From the time I logged into the laptop till it loaded the desktop icons I made the note of the timings and have saved the events generated on the event viewer on 2 different logon attempts. I am not able to attache the events file . so i have taken the snapshot.
At the same time if I disable the laptop Wi-Fi network connection and connect the laptop through a LAN cable to a wired
network. It log in within 40 seconds and also if I do gpupdate /force completes in 10 seconds.
The wireless is on separate subnet compared to wired network. We have three SSIDS and for each of them separate DHCP scope is created on the DHCP server. I tried logging in connecting the laptop to other 2 SSID and still the problem remains the same with delayed login.No sure where the underlying problem is, this is happening only with the wireless network.
Please guys any help to find the fault and resolve would be really great. Let me know if you need any further information.
Thanks in advance.

I am not sure if these is any firewall rules between these subnets .Our firewall is hosted outside our network and I don't have access and only when we need any ports to be opened, a request is raised and the firewall team open the firewall ports .
Apart from this we have core switches and I do have access to them and I didn't make any changes here.
This setup was working since fine since 1 year after implementation and all of sudden this behaviour.
I can ask our firewall team to check this if any policies are set up for the Wi-Fi subnets.

This is the same DNS server IP address used , when I do a ipconfig on PC that is connected to the wired network.
