Title: Certain Wireless Devices won't connect or are very slow
Post by: DWard on March 28, 2016, 05:43:38 AM
I just bought my 890L in October.  I have a cable modem connected to a switch for wired ethernet throughout the house.  the 890L provides wireless connectivity for primarily iPads but also a new Amazon Echo.  Certain specific devices, including one iPad, my iPhone, and the Echo, have a very difficult time connecting.  Sometimes Speedtest tells me they get 30Mbps, but most of the time they get less than 1Mbps or, frankly, nothing.  Just these 3 devices (all relatively new, so this isn't about old hardware).  I have tried using QoS to "favor" these devices, and when I reboot they will usually work, but then in a day or two they cannot connect again.  I have tried taking all the "cards" out of Qos (since some forums suggest turning off QoS) but that doesn't help either.  I am at my wit's end and about to junk this router and buy a new one.  Any ideas before I waste $300?

Router Placement
Forum User - "Well I feel really dumb. After moving the router away from other electronic devices my speeds are back to normal. Just a heads up for anyone experiencing slow speeds, you might want to move it away from other electronics and see if that helps."
3-6' feet minimum safe distance between devices.
Placement on main level floor and central in the building and WELL ventilated is preferred. Not in basements or closets as building materials, or near by electronics devices could interfere or hinder good signal propagation.
