WNDR4300 v2 Slow speed

[az6351]

Hi, I recently ran into an issue that my WNDR4300 v2 router has slow speed, especially for wired connection. For instance, online video stream start constant buffering 1-2 mins after opening; BT download speed remarkably fall from 2-3 Mb/s to 20-80 kb/s; Downloading in browser start with high speed but end up with 0 speed after serveral seconds. After I reboot the router the speed would come back for like 10- 20 mins and then falls again. If I plug my computer directly into port on the wall the speed would be normal.

I have 100Mbps Internet service. My firmware is 1.0.0.32.

I suggest that you contact support and get an RMA since it's not normal for the speed to drop.

Welcome to the community, @az6351

Did you try to factory reset the router? 

It might be possible that the router is slowly degrading. 

Have you also tried using all LAN ports available? Is it the same result for all?

Hi @ElaineM

Thanks for your reply. I have tried factory reset and 30-30-30 reset. Also changed different ports on the router. Still same problem.
