So for the last 3 days I've noticed numerous devices loosing WiFi intermittently but no impact the the ethernet devices. I did recently switch 2 Deco locations around. The ethernet clip on one isn't holding the cable securely so I've relocated this one to the basement as it won't be disturbed. it was previously in the living room and was touched by someone or something at some point or another and was probably the cause of it switching to wireless backhaul.

 

I am seeing pretty consistent WiFi disconnects on my Work laptop when I am connected to our Global Protect VPN. However my iPhone and other devices see the drop intermittently as well. 

I ran a ping from my laptop to the gateway and to google DNS server and can see some pretty high latency, no packet loss. 

 

--- 192.168.68.1 ping statistics ---
500 packets transmitted, 500 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 2.511/30.566/760.166/80.828 ms

 

--- 8.8.8.8 ping statistics ---
503 packets transmitted, 503 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 7.240/39.650/1054.565/90.206 ms 

 

Is there any known issues with Global Protect VPN? Why would I see such a high latency to the gateway?

I did confirm I am connected to my living room deco which is about 7 feet from where I'm sitting. I would think I should stay sub 25ms to the gateway.

  @DcMasta,

I would try and hardwire the laptop to see if the latency decreases any, that way, the wireless connection can be ruled out. 

 

VPNs work by bouncing your traffic around different servers, so it could be that your VPN is connected to a server that is difficult for the internet to router your signal too.

 

Have you run the latency test when you are not connected to the VPN to see if the latency still exists? 

 

You may also attempt to change the DNS server to Cloudflare to see if the latency follows.

 

 

For the dropped connections, there are a few settings that you can attempt to change such as beamforming, or fast roaming; which may affect how devices reconnect to the network's wireless bands. When the disconnect happens, do your phones and such remain connected to the network, does the wireless network continue to broadcast, and does this affect multiple units at one time?

 

 

 

As a side note, it is relatively easy to create your own ethernet cables and ends. If the securing clip breaks, you can order additional RJ45 Connectors and cut the older connector off the cable. Just make sure that you have a crimping tool.
