Hi @hk6230 ----- Thank you for the follow up and the clarification.
Moving forward, if this behavior is occurring outside of our application, I must be firm when I say this has to be related to some kind kind of network issue occurring in your setup. The two places I would STRONGLY recommend investigating are the following:
- TL-SG108E Gigabits Easy Smart Switch
- Did you experiment with enabling flow control on this device or give the link that Geoff posted a read?
- The ISP provided Zyxel PMG5318-B20B router.
- I would be hesitant to put 100% confidence in ISP provided gear, as we have seen users run into issues with these devices in the past. A good 802.11ac router as suggested here should be up to the task.
