X20 extremely slow ethernet speeds
Hi,
I am getting dial-up type speeds on my wired connection on PC but WiFi is working. My ISP data speed should be gigabit.
I have 2 - X20's and 1 - M4R.
Main X20 Deco is running FW 1.5.1
2nd X20 Deco is running FW 1.5.1Build 20210204 Re. 50738
M4R is running FW 1.4.3 Build 20200918 Rel. 74289
My set up is modem -> X20 Deco -> switch. Modem is in bridge mode. Both X20's are wired while M4 is wireless.
Speedtest thru Deco App shows speeds of 913Mbps down.
Speedtest on various cellphones range from 4-600Mbps.
Speedtest on PC is 6Mbps. Yes, that is SIX!
Speedtest on PC if connected directly to modem is 964Mbps.
After initial installation everything was running fine, wired and wireless. However last week I noticed that speeds on PC were atrocious.
After I tested connecting modem directly to PC and got gigabit speeds, I plugged everything back in, restarted main Deco and speeds on PC were 400is Mbps.
I updated the firmware on main Deco and speeds have maintained around 400Mbps for about 1 week.
Right now speeds have dropped back down between 6-9Mbps even after restarting main Deco.
I have tested wired speeds on 2 different PC's on 4 different ethernet connections and have swapped out all patch cables. Always get full speed when main deco is unplugged so have ruled out cables, ports, PC's (firmware/hardware), modem, switch or ISP issues.
I have searched for solutions but was unable to find anything. Any help is greatly appreciated.
