PC with a 4 port GbE NIC running PFSense and a Ubiquiti AC Lite AP. Since<br>
the upgrade I have been experiencing intermittent latency spikes peaking<br>
between 5000ms and 10000ms lasting for anywhere between 3 and 5 minutes.<br>
There seems to be no regular interval that I can determine as my wife has<br>
reported these issues during the day and I've experienced them firsthand<br>
when I get home from work. Some days I will see several in the course of<br>
an hour or two and other times we'll go days without seeing it a single<br>
time.<br>
<br>
I was curious if anyone here has seen similar behavior before and might<br>
be able to provide some clues as the it's source. Originally I thought<br>
that this issue was related to my ISP but a ping test against my local<br>
gateway shows that it persists when communicating with devices on the<br>
same local network. The last set of tests I ran to determine that the<br>
latency existed on the local network was done while connected to the<br>
wireless. By the time I finished testing from the wireless last time and<br>
got down the basement to try while plugged directly in to the PFSense<br>
box the latency has subsided. It has not re-appeared since (about a week<br>
now).<br>
<br>
Aside from confirming whether the latency persists on the wired network,<br>
what other steps should I take? Are there any settings on either the<br>
PFSense box or the Ubiquiti AP that could cause this? Perhaps some<br>
confirmation conflict between the two devices that I'm not seeing? One<br>
thing I should probably also mention is that this issue persists across<br>
devices. We usually notice the latency spike occur while watching<br>
Netflix on the living room TV (a Samsung "smart" TV) and I can confirm<br>
the latency on both my personal and work laptops as well as my phone.<br>
All of these devices are connected to the same SSID. I have not tested<br>
it from the guest SSID.<br>
<br>
Thanks in advance for any information or advice. This issue has been a<br>
real pain in the arse. Finding a solution here would make for a happy<br>
household once again.<br>
