C5400X - Internet Speed issue
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
I have a TP-Link C5400X router with the latest firmware. All of my PCs are hardwired. LAN transfer speeds are fast, as tested by iPerf (~115-120 MB/s, 950 Mb/s).
I have gigabit internet, but my internet SpeedTests will only show around 350Mbps. If I reboot my router or change something like DNS or renew lease, the tests will be fast at >900Mbps. After a little bit of time (couple of hours), it’ll slow back down to 350Mbps (while iPerf remains fast) for all my PCs. Network monitoring on the router shows no bandwidth hogs when the slowdown occurs.
My previous Netgear Nighthawk router did not have this problem.
Any thoughts?

@Carl I'm still having the issue. I reset the router to factory reset and then put all my settings in
