Title: DIR-810L Wireless Router extremely slow and drops the connection
Post by: abacabb on June 08, 2015, 11:58:51 AM

My new DIR-810L Wireless Router is extremely slow and drops the connection for 3 different laptops in my house.  I had an older dlink router that extended my current wifi connection from my AT&T modem and it never dropped the connection to any of my devices.  This one seems to roll in and out.  I had DNS relay enabled but it made browsing the web extremely slow so I had to turn it off.  I used the wizard initially to setup the connection DHCP, etc.  It's on the newest firmware 2.03.B02.  Is there settings I should change manually on either the router or the modem?

Odd thing is it seemed to be running extremely nice when I first installed it and set it up.  It was about a week or so I noticed it having issues.

• 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?
• 2.4Ghz and 5Ghz routers: Try single mode G or N or mixed G and N on 2.4Ghz and single mode N or AC on 5Ghz?
• 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. Try channel 48 or 149 on 5Ghz.
• 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.
• What wireless devices do you have connected?
• Ensure any devices with WiFi adapter drivers are updated.
• 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 (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.

Hello,

Thank you for the tips, I will try them out when I get home.  Do you know if these would fix the issue of the connection dropping?  I'll be on my laptop with full signal and all of a sudden it drops down to 0-1 bars.  Also, simple small downloads/uploads that took seconds before take up to 10-30 minutes.

Possible. Also we need more information regarding this so please answer the questions presented so we can get a better idea of your system. Most reason why there is a loss of connection is usually other wireless interferences.
