USG60W Throughout went from 500Mbps download to 70Mbps after UTP services expired

Hi Team,

My USG60W performance has went down from 500Mbps down to 70Mbps shortly after my UTP services expired. I only really tested the Content Filtering service for one month and everything was disabled. Now I have disabled content filtering and I still get poor speeds.

I have already connected directly to my router and I am getting the correct speeds so there is no problem with my ISP.

@Zyxel_Stanley any thoughts? Nothing changed in my configuration.

Thanks

I have discovered the problem. It looks like I had to set the ports to auto negotiate (already on that before). Went through the logs and all I did was a graceful shutdown and startup but this shouldn't have happened surely?!?!?!

Hi @RCP,
Supposedly this shouldn't happen. If you reboot the ISP router again, will the same symptoms occur?

Hi @Zyxel_Cooldia,

I've tested again and it did happen, unplugging and plugging the WAN cables fixes, same if I move the ports from auto negotiate and back.

Hi @RCP,

It could be related to NIC compatibility and operation Issues. It causes dropped packets, reduced throughput, and session drops.

You can try to connected a dummy switch between USG60W and ISP router to see if it is helpful about this issue.
