R6700 Slow Ethernet Speed

[heedafaf]

I'm using this router in AP mode and the other router is working fine.  If I reboot the router is will get over 200 Mbps but within a few minutes it will drop down to 20-50 Mbps - both test in a wired connection.  

V1.0.4.120_10.0.91

Any suggestions on what to try?

Have you tried a factory reset?

Did it just start or has it been going on for a while? (if so, how long)

Thanks for the reply.  I did a reset and it didn't help.  About 10 minutes later it went from 200+ down to 20-50.

Does it stay constant in router mode? maybe the primary router you're using has a qos thats slowing it down

Disabled AP mode off it didn't help. The QoS on the other router is off and has never been on.  Any other ideas?  Very perplexing.

what is the primary router?

TP Link ax1800

*AX1800 is a speed not a model*

If you swap the tplink and the r6700 with the r6700 in router mode, is it still slow?
