Welcome!- Was a Factory Reset performed before and after any firmware updates then set up from scratch?
>FW Update Process- Was the router working before any firmware updates?
Internet Service Provider and Modem Configurations- What ISP Service do you have? Cable or DSL?
- What ISP Modem Mfr. and model # do you have?
- Is ISP Modem/Service using Dynamic or Static WAN IP addressing?
- What ISP Modem service link speeds UP and Down do you have? Link> Speed Testing Sites
- By-pass the main host router and check internet connection by connecting a wired LAN PC directly to the ISP modem to verify connection access and ISP speeds.
- Check cable between Modem and Router, swap out to be sure. Link> Cat6 is recommended.
- Check ISP MTU requirements, Cable is usually 1500, DSL is around 1492 down to 1472. Call the ISP and ask. Link>Checking MTU Values

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?
Forcing 40Mhz is not supported on newer generation D-Linkrouters due to the
Good Neighbour Policy. - 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.
- If you have any of these options, Try turning OFF or ON Short GI, 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.
Disabling HT 20/40Mhz Co-existence is recommended when using single mode N only.
Router PlacementForum 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.
http://www.smallnetbuilder.com/wireless/wireless-basics/31083-smallnetbuilders-wireless-faq-the-essentialsWhat Mfr and model device are you testing with wirelessly?
Its not really recommended to speed test via WiFi due to many variables that can cause inaccurate results....Mfr wireless device design and support will be a factor. We don't recommend speed testing over WiFi as a default test due to issues like this and many other factors and variables that lead to inaccurate results. Testing over wired LAN cables for default speed tests is preferred.
Here are my results. I just got the DGL-5500 a couple of weeks ago off Amazon. I am running the latest firmware 1.13.b04.
Does anyone know if the channel width can be set manually instead of AUTO 20/40? I can set 20Mhz but I want to force only 40Mhz band on the 2.4Ghz Band. I have tried disabling the Coexist HT 20/40 Band but my speeds drop drastically on the 2.4Ghz Band when that feature is disabled.
