Title: Android device connection issues
Post by: jimtn on January 02, 2015, 09:10:53 AM

Have several Android devices that suddenly will not connect to internet.  They connect to router.  Resetting  router will temporarily fix problem .  This has been an ongoing problem for months, made worse by have more Android devices.  IOS devices do not have this problem, not do laptops. No problems wire wired connections which has 4 computers, two sat dishes and 1 smart TV

Comcast internet  cable modem is aa Arris WBM760A

Router DIR-655  B1 2.11NA

Have tried all the config info listed in stickey  threads.  Any other suggestions.

Thanks

• What region are you located?
• Has a Factory Reset (http://blog.dlink.com/what-is-a-reset-button-when-should-i-use-it) been performed?
• Was a Factory Reset performed before and after any firmware updates then set up from scratch?

FW Update Process (http://forums.dlink.com/index.php?topic=42457.0)

• Was the router working before any firmware updates?

• Ensure the default (dlink) SSID name is changed. Can be anything and not something that's already in use by any neighboring WiFi routers. Under Setup/Wireless/Manual.
• What wireless modes are you using?
• 2.4Ghz Routers only: Try single mode G or N or mixed G and N?
• Channel Width set for Auto 20/40Mhz or try 20Mhz only.
• Try setting a manual Channel (http://en.wikipedia.org/wiki/Wireless_channels) to a open or unused channel. 1, 6 or 11. 11 for single mode N if the channel is clear. 13 for EU regions.
• What security mode are you using? Preferred security is WPA-Personal. WPA2/AES Only. Some WiFi adapters don't support AES (http://en.wikipedia.org/wiki/Advanced_Encryption_Standard), so you might want to try TPIK (http://en.wikipedia.org/wiki/Temporal_Key_Integrity_Protocol) only or Auto TPIK and AES.
• Any 2.4Ghz or 5Ghz cordless house phones or WiFi APs near by?
• Any other WiFi routers in the area? Link> Use InSSIDer (http://www.techspot.com/downloads/5936-inssider.html) to find out. How many? Use v3, its free.
• If you have any of these options, Try turning OFF or ON Short GI (http://www.smallnetbuilder.com/wireless/wireless-features/30969-what-do-80211ns-optional-features-mean-for-you), WLAN Partition, Extra Wireless Protection and HT 20/40 Co-existence if you have it. Also testing with HT20/40Mhz Co-existence enabled will impact results as well. I prefer to use this option OFF. Recommended settings are default. Under Advanced/Advanced Wireless.

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.
