In my original post, can't attain the 600Mbps connection for wireless N.  Checking the site below, it seems that the specs indicates a maximum of 450Mbps connection rate.

     http://www.dlink.ru/lv/products/2/1931_b.html

Attained the above speed theoretically with 220Mbps++ of actual connection.  Now I'm done.  Thanks to all your replies.

I wonder if thats a typo.
I see 600mb is listed here:
http://us.dlink.com/products/connect/ac1900-wi-fi-router/
Again, your client HW has to support the connection rate regardless of 600 or 450mb.
Good Luck.

I've used my smartphone, iPad2 mini and laptop PC which are able to connect to AC3200 and AC1900 wireless AP at dual mode N600 in our office  but their connections register at 450 in DIR-880L and sometimes switching 215M from time to time.  There are no other active nor hidden WiFi SSIDs in our vicinity.  But I'm happy with the present setup.

Thats probably the max connection rates they support.

I'll forward the link you sent me to my contact to have them check on the accuracy of the web site information.

Thank you.

Just to show the connection I'm getting from my DIR-880L, see channel 1+5 in the attached image for WiFi N connection.



Channel 11-7 is my DIR-655L which tops at advertised 300MBps, unlike my 600MBbps of DIR-880L at 450MBps only
2 PCs, 2 smartphone and 1 tablet of mine show the same maximum rate so client adapters don't matter in my opinion.

Thanks for posting what your seeing. I see the rates however client adapter rates do matter in regards to there support of there designed connection rates. You need to make sure those adapters support 600Mb connection rates as this is relevant to the situation. Contact the Mfr of these adapters to confirm there official connect rate support.

What Mfr and model are these adapters and devices?

There could be some issue with the FW if you can confirm that the adapters officially support 600Mb on 2.4ghz.

What is the Mfr and model of the routers tested at the office?

I have forwarded the linked web site on to a regional contact to review whats posted on the web site.

For the notebook, it's Lenovo ThinkPad X1 Carbon Type 20A8
For the smartphone, it's Lenovo Vibe Z2 Pro
For the tablet, its Apple's iPad mini 2 Wi‑Fi + Cellular model.

All of these supports 802.11ac so I assume that 1300mbps display also supports N600 MIMO connection on all these gadgets.
But if it very difficult to check 802.11n max speed connection just checking its datasheet or product specs.  Unless, its wireless chip specs should be confirmed.

If they support AC mode then thats only on 5Ghz AC, not 2.4Ghz N mode. AC mode is NOT supported on 2.4Ghz. You need to find out what they support from the Mfr on 2.4ghz and 5Ghz for each mode. If AC is support then I presume they could support up to 1300Mb on 5ghz, however I think the Apple only supports up to 450Mb on AC as My Mac Mini has AC support however in testing and confirmed with D-Link, it only supports up to 450Mb on AC 45Ghz. I'll have to check my Mini I have at home. Its a mini 3 I think.

I appreciate for your prompt response.  I apologize that my post seems getting in circle.  I'm aware of the 80.2.11ac specs operates at 5GHz spectrum.  For my ThinkPad and Vibe Z2 Pro, I confirmed its 802.11n support for both 2.4GHz and 5GHz or MIMO capabilities because in NetGear & ASUS AC1900 router, it registers WiFi-N connection and indicates max data rate of 600Mbps.  Anyway, this is just theoretical speed but I was hoping that there is a setting in DIR-880L that can set to connect at 600MHz.  These settings/monitoring screens are present in old wifi N/AC routers. 

Just a wishlist that there is someway the following  features would be restored
1. WiFi transmission rate setting (1mbps, 2, 54, 130 300...)
2. WPA cipher mode (TKIP/AES)  setting.  I believe the WPA2/AES would achieve the highest transmission rate setting
3. WMM enable setting
4. device info screen for all network related connection
5. log details viewable within its WebGUI (syslog requires external storage and viewing)
6. connecting gadgets/terminals' wireless mode connection mode/rate/signal
7. internet session screen, other than the statistics graph screen
8. details QOS engine rules to further control multimedia connection.

As said these are just wishlist so I hope D-Link would check upon these features and weigh in its usability.  Thanks again.

Ok, thanks for posting the information about the other router. If that router support 600Mb and that connection rate was seen on that router, and you can't see it on the 880L, then I presume there maybe an issue with the 880L in the FW. I recommend that you phone contact your regional D-Link support office and ask for help and information regarding this. We find that phone contact has better immediate results over using email.

"2. WPA cipher mode (TKIP/AES)  setting.  I believe the WPA2/AES would achieve the highest transmission rate setting" You can set WPA2/AES only on the UI for both radios if you have not tested this already.

Please feel free to add your requests here:

Sorry but the UI only indicates the setting below:



May I know where I can set to WPA2/AES only?  Or are you referring to the setting of connecting terminal in WPA2/AES mode?

What part of SW Asia are you located if your still in that region? I need more specific area please.

When using WPA/WPA2 mode, the router auto detects what the best mode should be. I presume if the connected device supports WPA2/AES the router will use this mode. Most new generation devices all support WPA2/AES now days since WEP is less secure and WPA and TPIK are used on older generation devices for compatibility.

I'll set up my 880L to connect to my 890L since it supports 600Mb on 2.4Ghz and see if I can figure out how to tell it's connected. These are the only 2 devices that I have that support 600Mb currently. I'll post my results here. I would recommend contacting your support office on the phone and discuss this with them. Let them know you tested on a different router to verify the supported rates on each device and that this model router doesn't seem to operate as expected.

Mine is Southeast Asian/Philippine unit. Thanks for the time and effort. To report this, I need to call Singapore as our regional hub. Keep us posted.
