We have four locations. Only 1 location is experiencing heavy packet loss with these particular phones. We notice T29G, T27G, T53’s work fine. But any of these other phones, T23G, T43U, and T33G have massive packet loss like 5-15%.
We have narrowed the phones down on 1 switch, we have vlan’ed them and segmented them off in small groups, we have tried many different switches, even different brands. We have shut down the entire buildings electrical, and just fired up the switch to eliminate any interference.
When we take the phone and shut off the native VLAN; the problem stops. But once we turn that on; its as-if the phone is listening to the native vlan and getting bogged down by something; even in small groups.
Initially I thought it was the phones, then we started replacing switches, we also isolated any interference down by shutting down everything electrical nearby and just ran isolated tests.
We finally did a test where we shutdown all the PC’s only one evening and then ran the tests; the problem disappeared. So one thing we have out there is bunch of Windows 11 machines; and not alot of internet traffic flowing; our network is overkill. But whatever these machines are sending out, multicast, mdns, something, malware… Nothing is preventing it from bleeding over to affecting the phones.
Phones are on their own vLAN (they receive the detail\option from DHCP 139)
and all the computers are on their own VLANs
If you turn the VLAN off for native data on that port; the problem goes away, but once it has any visibility to the affected vlans; ping starts to drop. This is not the case on any of our other rollouts with Peplink and these phone deployments.
Is there something the Peplink can do to filter or block all this noise from these machines? Or do I need some other kind of firewall or tech to combat this issue? Or do I need to wipe all these machines and start over?
We not only see packet loss on ping plotter, but we see lag spikes from any pc behind the phone… (see command line ping)
