Title: 2.4GH is missing but the name is used for the Primary 5GH
Post by: rafaeltorchelsen on December 07, 2016, 06:28:29 PM
I have a Model Name: DIR-895L Hardware Version: A1 Firmware Version: 1.12.
I have it for a month and the signal was never great and now Iīm having a strange problem.
This is the configuration:

However what I see on a computer 1 meter from the station is only this:

(https://rafaeltorchelsen.files.wordpress.com/2016/10/wifi2.jpg)
 
Not that the name I gave for the 2.4 is used in a 5GHz and the 2.4 is missing. Also, note how low the signal is given that the computer is very close to the station. The smart connection is off.
I already did a factory reset and power down.
Someone can help me? Thanks

When Smart Connect is disabled, you need to give each radio SSID a different name. They can't be the same. Only when SC is enabled, can a single SSID name be used.

 The region is Brazil.

 The SSID is different for each as you can see in the first image.
 I think it is a hardware or firmware problem, because the names end up mixed and the 2.4GH insīt transmitting, but it is on as you can see in the first image.

Thanks!

Ok, use the slider buttons and disable both 5Ghz radios and leave the 2.4Ghz enabled. Does it appear at all then?

I did as you instructed and it does not appear as a 2.4Ghz, but as a 5Ghz using the SSID I gave to the 2.4Ghz.
Thanks

Do you have an android phone?  Try wifi analyzer app.

If trying a different wifi analyzer doesn't produce something different, I recommend that you phone contact your regional D-Link support office and ask for help and information regarding this. This unit needs to be RMAd. We find that phone contact has better immediate results over using email.


Let us know how it goes please.

I had this same issue very frustrating and time consuming. I called support who had me try various things to no avail at the end of the call tech support asked me to downgrade to 1.11. I did this and noticed no change. I then retyped all the SSID's and retyped all the passwords and saved.  After downgrade and SSID\Password changes I found that if I powered off the router and waited a few minutes and powered back on everything returned to normal. I plan to test this further as I would like to use the latest firmware 1.13. Anyway hopefully this helps someone else resolve this quickly instead of the 1-2 days I spent on this.

Downgrade to 1.11 (For me I did not have to do a restore to factory)
Rename SSID and Password and save. (I just typed in all the info again and not sure if this step is
needed)
Turn off the router for 2-5 mins and power back on. (I just used the button on the back)

What region are you located?
USA - Central

Was the router working before any firmware updates?
I have always had issues with 2.4ghz connection. Worked off and on for a few months after upgrade to 1.12. Had to restore factory a few timse. Then this issue started and had to downgrade.

What ISP Service do you have? Cable or DSL? Uverse
What ISP Modem Mfr. and model # do you have? Arris
Not sure I understand the need for this info?

Reason for asking for model and mfr of ISP modem is to confirm weather or not it has a built in router and wifi. As this can be a cause of problems with external routers.

After almost throwing out all my 2.4GHz only devices now I relapse the problem is actually with the Dkink!

I've been having the same problem. Despite turning off the smart connect it doesn't seem like 2.4 is available at all. And so far having really poor performance. I'm thinking about downgrading to FW 1.11 actually

No unfortunately it has not. Everything from 1.11-1.13 didn't work. I think my unit is faulty... calling a local support now to get it exchanged or fixed.

Is there a way to let Dlink know this is a prominent issue that needs to be patched where possible? It seems many are having this problem on this forum.

Let us know how it goes with support. There's been only you and a couple others at this time frame that have been posting about this issue.
While you still have the router, can you test by loading FW versions older than v1.11? Just to see. Be sure to factory reset first, then load FW, then factory reset and check.

I'll forward this onto D-Link support for review.

Sounds like you had a bad unit. Glad the new one is working well now.

Could you satisfy my curiosity and show a screenshot like you did in your orginal post, showing the networks of the new router? My guess is the 2.4Ghz issue has something to do with the older Wifi G networks around you. As for the 5Ghz, I think that has something to do with the secondary 5Ghz SSID and being TOO close to the router. Beam forming can do some funny things when dealing with multiple network and close distance.

With my new unit now and suffering the same old issue after 2 weeks of usage. I am not sure why this problem persists now that it is a new unit.
All of a sudden 2.4Ghz is just gone.

What version of FW came loaded on the replacement unit?

- ISP modem is from the ISP and it shouldn't have any interference with the unit given Wi-Fi is completely off and it is set to bridge mode.

What version of FW came loaded on the replacement unit?
Is Smart Connect enabled or disabled?

Came with v1.11 but then it kept asking me to upgrade to without an option to ignore the message so in the end upgraded to v1.12 but everything was functioning fine for 2 full weeks until one day I came back home to find out that my TV (2.4GHz only) is no longer connected to the router. It's always been set to Smart Connect.

I then tried disabling Smart Connect to see what's wrong with 2.4GHz, then same issue persisted where it doesn't matter what I do, the setting for 2.4GHz seems to be instead working for 5GHz for whatever reason.


Any 2.4Ghz or 5Ghz cordless house phones or WiFi APs near by that maybe causing interferences?

I have no cordless phones. WiFi APs near this is out of my control given I live in an apartment building but there is none that could potentially causing that massive interference.

Any other WiFi routers in the area that maybe causing interferences? Link> Use a WiFi Scanner to find out. How many?
There are up to 4 that could potentially cause interference on both 5Ghz and 2.4GHz.

Please downgrade to v1.11.

"There are up to 4 that could potentially cause interference on both 5Ghz and 2.4GHz." What channels are they using?
