Hello,
All the Iphones, Ipads, Nintendo DS XL, PS Vita, and Samsung Galaxy cannot connect to this 2.4 channel only 5. How can I check the if the radio bandwidth is clogged? Thanks a lot.

It scans for all local 2.4GHz radio networks. There are atleast 3 different bands of frequences which do not interrupt each other. Sometimes these routers do not manage these frequencies on their own.
