Dlink Dir820 router band problems
« on: October 03, 2015, 05:05:52 PM »

My D Link Dir820L  works fine .. but I have an issue that I wanted to clarify in this post and fix . .or understand ..

This router has duel band 2.4Ghz  and 5.0 Ghz..  both channels work and are setup for password ..  question I have is :

when I do a search for my network available and see that I am currently logged into the 2.4 channel if I log out of this area and then setup and enter the 5.0 ghz .. it logs in and I can surf the net etc .. but within seconds it will change over to the 2.4 ghz  all by itself ..  I realize the dual band router with the second band of  5 ghz  band is not as  'popular'  as my 2.4ghz   but why the switch over  ??

Reason why I am exploring this area is when I am logged in my wireless to view Netflicks thru my Blue ray player to my Big screen TV .. the signal is okay  ( seems to fluctuate  between 240p and 480p  and occasionally up to 720p) ..  all my smartphone using the same 2.4 ghz I get no internet on my phone.. its like the netflicks is 'sucking the 2.4ghz  bandwidth dry' and therefore no internet with smartphone  using ALL THE  2.4ghz to run my netflicks WIRELESS viewing  .. 
so I then switch the phone to the the second band  ( 5.0ghz)  which appears to work.. but seconds later I relaize I am back to the 2.4 band ... 


Ideas ?????

Link>Welcome!

  • What Hardware version is your router? Look at sticker under the router case.

  • What region are you located?

Internet Service Provider and Modem Configurations

Wireless Configurations
Links>Wireless Installation Considerations and Managing Signal Congestion and Good Neighbour Policy
  • Ensure the default (dlink) SSID name is changed. Ensure that different SSID names are used between each WiFi 2.4/5Ghz radios. Can be anything and not something that's already in use by any neighbouring WiFi routers. Under Setup/Wireless/Manual.
  • What wireless modes are you using?
  • Any 2.4Ghz or 5Ghz cordless house phones or WiFi APs near by that maybe causing interferences?
  • Any other WiFi routers in the area that maybe causing interferences? Link> Use InSSIDer to find out. How many? Use v3, its free.

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.
