Wireless connection dropping

Post by barnburner » Sat Dec 09, 2017 11:14 pm

Hope someone here can help me figure out why my wireless connection drops and reconnects at random intervals. However, if I open a terminal and run a ping the connection will not drop while the ping is running. If I stop the ping I notice the same behavior, wireless connection drops and reconnects after a while. If you can assist please let me know what information is beneficial. I can post logs and provide detail.

Help is greatly appreciated. Thanks...

Router is a Linksys EA7500. What else might be useful?
