Short disconnections both on 2,4 and 5
« on: August 14, 2016, 12:54:01 PM »

HI,

FIrst of all I want to say that I am musing the A1 version and I am from Romania.

I used DIR-868L Rev A Patch v1.10 B04 WW Region version which allowed me on the 5GHZ wireless to download at very high speed - 26mb/s.
The 2,4 wireless was also good.
Problem is when I brought home my laptop from work. I use Lync and there I could see I am having short disconnections on both wireless networks. I confirm the problem is not with the laptop. I also installed hamachi on my gaming laptop and opened a tab with my brother where I saw I was having short disconnections as well. It doesn't affect me when playing or anything else but when working I am logged out of Lync so there is a problem.

Now I switched to DIR-868L Rev A Patch v1.10 B04 FaceBook Edition - NA Region Only! which seems more stable (but I will update tomorrow) and I see my download speed dropped to 10 mb/s. Any ideas why?

Link>Welcome!

  • Was a Factory Reset performed before and after any firmware updates then set up from scratch?
  Link> >FW Update Process


Internet Service Provider and Modem Configurations
  • What ISP Service do you have? Cable or DSL?
  • What ISP Modem Mfr. and model # do you have?
  • What ISP Modem service link speeds UP and Down do you have? Link> Speed Testing Sites

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?
  • 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 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, so you might want to try TPIK 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 a WiFi Scanner to find out. How many?
  • 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.

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.

So the router was working well until you brought a laptop from work home and used Lync and then you noticed this short disconnection?
What OS platform is on this laptop?

I would return the routers FW to v1.10B04 WW as the FB version is not supported in your region and seems to be adversely effecting your router.

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. - I have different names
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? - I tried N, A and AC on the 5Ghz but best option is "all"
Channel Width set for Auto 20/40Mhz or try 20Mhz only.  - channel is set to 20/40/80
Try setting a manual Channel 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. - Strange but I can only choose channels 36,40,44 and 48. I checked 48
What security mode are you using? Preferred security is WPA-Personal. WPA2/AES Only. Some WiFi adapters don't support AES, so you might want to try TPIK only or Auto TPIK and AES. - WPA-Personal
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?

"What security mode are you using? Preferred security is WPA-Personal. WPA2/AES Only. Some WiFi adapters don't support AES, so you might want to try TPIK only or Auto TPIK and AES. - WPA-Personal" Try WPA2 and AES only before downgrading FW.
