I have a DIR-890l, version A1, firmware 111b02_20170519_beta01. My internet is Spectrum 60 Mbps but I can't get speeds any faster than 19.1 Mbps. Doesn't matter if I am connected with a hard ethernet connection or a wireless connection, my speeds are capped at 19.1 Mbps. I run the band width detect in the QoS Engine section it detects my upload is 6 Mbps and my download is 60 Mbps. Am I missing something or could I have something set incorrectly in the router setup?
I had a Spectrum tech here and he replaced my modem, reprogrammed my modem, verified my account settings are correct, and replaced my ethernet cable with no changes to my speed using speedtest.net. He disconnected my 890l and plugged in his own Netgear router and the connection tested at 48 Mbps via speedtest.net. We plugged my 890l back in and it maxed out at 19.1 Mbps. I have 29 devices connected to my router.
Any help would be greatly appreciated. Thanks in advance!
