Wireless Intermittent laptop connectivity

[edpmrc23]

Hello everyone,

First time poster here. We are trying a slow migration of Cisco & Ubiquiti devices, but we are having some Wi-Fi connection issues.

So, the problem:

We plugged in two of our AP's DIRECTLY into the Dream Machine and created the Networks. Everything was running beautifully! We were able to get the public network going and the Radius Server connections. On top of it, we were getting EXCELLENT speeds. We verified everything was working well and decided to move to the next step: plugging the AP's into the Cisco switch.

We currently have the Dream Machine connected to our Core Switch and our AP's connected to the same Core (Cisco) switch. We have configured the ports to be trunks allowing for our current VLAN's and the VLAN's created for our Ubiquiti networks. However, we are unable to connect, we get the dreaded "Connected, no internet" message. But, when we do connect, it is extremely slow and drops quickly!

Update!  Made some progress, but I still have issues on the cisco switch our phones connected/stayed connected without any issues, but our laptops can't seem to say connected. The laptops will connect to the Unifi AP, receive an IP address of 192.168.152.x from Mr.Public, able to access the internet and browse like normal for 5-45 min then drops. Mr. Public WiFi says "No Internet, secured." Also, even with No Internet, secured on laptop I am still able to see it as a client with poor experience on Unifi with an IP address of 192.16.152.x and I verified the IP address on laptop WiFi Mr.Public IP settings & ipconfig /all. So connecting to the Unifi AP is not the problem. I thought it might be some Unifi firewall rules that I created, but I paused all the rules I created and the issue is the same. I think it might be a cisco switch or router setting/configuration. Any suggestions?

Hi,

So this issue started when you connect the APs to the new Cisco switch? Was it all working before with the other vendor's switch?

Can you post the output of "sh run" from the switch and point out to what ports the APs are connected?

Hi Reza,

Yes we were able to get the Ubiquiti Dream Machine Pro and 4 - U6-LR AP's to mirror, but function independently of our current Cisco network providing wireless Public and Radius networks. Attached are the setting for our Cisco switch. FYI port GE#1/0/21 is used so we can view the GUI of our UDM-pro without that link we are unable to see the Unifi GUI/devices.

@edpmrc23 hi, check the logs in switches and routers in between to identify any abnormal logs, check interface counters and status of AP connected ports in cisco switch. check interface bandwidth utilization of cisco switch when issue is happening. 

keep continues ping to default gateway and internet IP (8.8.8.8) and monitor for delay and drops.

Kasun,

I will try that thank you.
