Title: Problem with 2.4 Ghz Performance
Post by: selarom on August 10, 2016, 05:52:12 PM
Hello All,

My 880L has a problem where it looses connectivity for its 2.4ghz network. Wired and 5ghz are fine... But if I connect to the 2.4ghz network, it takes a long time to authenticate and if it does, then the connection is very bad. I get less than 1Mbps speed. If I reboot the router, it works fine for a while then the connection drops.

I tried factory reset and updating to the latest firmware without sucess.

Some more info.
It didn't do this at the beginning a few months back.. I started happening about a month ago.
My 2.4ghz and 5ghz networks are distinguished by the 5ghz SSID having a "-5ghz" at the end.
They both have the same password.
I also have a DAP -1650 which has different SSID, but password is the same. It is used as an access point. It also has both networks working with no problem.

Has anyone seen this behavior?  Could this be a bad unit?

What are you using to connect with that is causing such a bad rate?

Are all your 2.4 Ghz devices exhibiting this behavior?

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.

Turn OFF the DAP-1650 and test the 880L alone.
