For the past few months, I have had random packet bursts dropping my internet for a few seconds or a few minutes. The packet burst usually happens every 20-30 minutes. AT&T has sent out 2 technicians that have swapped out my routers, and neither fixed the issue. The issue started after AT&T came out and rewired outside, and have not fixed the issue since. I have swapped the ethernet cable as well. This is all an issue while hardwired and wireless. My speedtest is fine, the issue is just annoying having a disconnect every 20-30 minutes because of packet burst. I have tested it all on my end. The issue started when AT&T came out and changed wiring outside. Anyone know a fix?
