Title: 5.0GHz signal disappeared?
Post by: Encyclia on September 08, 2016, 01:23:09 PM
Hello,
I am a real rookie at this stuff, but my router recently stopped broadcasting the 5.0GHz version of my signal. The 2.4GHz version still seems to work fine. None of my devices can connect to the 5.0GHz signal including my phone, Roku, etc. when they used to work just fine.

I tried to set the router up again through the connection wizard and I tried updating the firmware to 1.10 (successfully, it appears).

Thanks very much for any help you can provide.

Mark

What Hardware version is your router? A1
Link>What Firmware version is currently loaded? 1.10
What region are you located? United States
Was a Factory Reset performed before and after any firmware updates then set up from scratch? Not the first time, but I just went through and did one and gave it a new name.

What ISP Service do you have? Cable or DSL? Fiber through the city of Longmont, CO.
What ISP Modem Mfr. and model # do you have? Calix/Anatel 716GE-I

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. Already done.
What wireless modes are you using? The default? 2.4 and 5.0 2.4 works, 5.0 doesn't
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 don't know what this means.
Channel Width set for Auto 20/40Mhz or try 20Mhz only. I don't know what this means.
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. I don't know what this means.
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. I think is WPA2, but not sure. Password is 32 characters long.
What wireless devices do you have connected? Do they support 5Ghz? Roku, Smart TV, phones - all used to use the 5.0 and now they can't
Ensure any devices with WiFi adapter drivers are updated. N/A
Any 2.4Ghz or 5Ghz cordless house phones or WiFi APs near by that maybe causing interferences? Not that I am aware of. We are in a house, not an apartment. No new signals in the list.
Any other WiFi routers in the area that maybe causing interferences? Link> Use a WiFi Scanner to find out. How many?

Thanks!

Log into the router and see it its been turned off. If so, turn it back on. That should be your fist action taken.

Once you do a factory reset, both radios should be enabled by default and will have default SSID names. Change both names to some thing different and keep separate.
I would try one test where you disable WPA security temporarily and then test to see if any of your devices see's the 5Ghz ssid name and connect. If so then turn ON WPA Personal and set WPA2 and AES only and test.

Ok, I disabled the security by setting Security Mode to "None." Sure enough, the 5.0GHz SSID was visible and connected just fine on my phone and Roku box. I then set the Security Mode back to WPA-Personal and chose "WPA Only" for the WPA mode and "AES" for the Cipher Type. The radio disappears again with these settings.

Thanks again for helping me,

Mark

Does setting WPA2 and TPIK show?
Title: Re: 5.0GHz signal disappeared?
Post by: Encyclia on September 14, 2016, 05:58:47 AM
Nope, doesn't show with those settings. 2.4 is fine in all of the modes you have suggested, though.

Thanks!

Ya, this is odd, 5Ghz works with out WPA then doesn't when it's activated.
Can you tired all of your 5Ghz supporting devices while WPA was enable?
How long have you had this unit? May need to get this unit RMAd.  :-\

Yes, I did try both my phone and Roku. I agree it's strange :-) It may be time to call D-Link support and see if they will take it back.

Thanks again for all of your help.

Ya see if there is an RMA option. This is a great router too. Let us know how it goes.

Turn off smartconnect. When I turned that off the 5GHZ channel came up for both Guest and normal. Make sure they're named differently though. Both were named the same so I added "5GHZ" to each 5GHZ channel.

Hopefully the OP has found his solution since it's been 4 years. Thanks for posting.
