Title: Maximum Date Rate of Wireless N
Post by: nettewurk on March 27, 2015, 11:07:14 AM
I'm using inSSIDer 4 on Lenovo X61 with Intel Wireless 4965AGN.  It detected both my 2.4GHz and 5GHz SSIDs.  However, checking their maximum data rate, the 5GHz indicates 1300 but its 2.4GHz only indicates 216.7, instead of 300 or even 600 as advertised.  Checking my other access points, both my DIR-655 and DIR-636L indicate 300.  I thought that the Wireless N can give as high 600 throughput.  All of them are set to hidden SSID, maximum high rate/power setting, same encryption type and almost same location with different channel ID and 20/40 auto channel width.  Any idea why I can't obtain 600 Mbits/sec?

Does your Wifi adapter support 600Mb connections on 2.4Ghz? If not, then this would be the reason.

As said, not only 600 but I can't also get 300, only 216 unlike the other WiFi router I indicated.  The adapter's specs includes only WiFi A but the rate is 1300Mbps, how's that?  (http://C:\Users\rcalzado\Pictures\WiFi-Info.png)

1300Mb on 5ghz. From the spec, this adapter only supports up to 300Mb on 2.4Ghz.

Please don't use red on the gray background.

Again, as said not 300Mbits but 216 only while for my DIR-655 and DIR-636L, all indicate 300M exactly.  For 5GHz, can't see AC support but A only with 5GHz radio frequency. But it suggests to use WiFi N to reach until 300M, and not 1300M as you indicated.

http://www.intel.com/products/wireless/wireless_n/overview.htm

Given the 655 and 636L, 880L cannot give me at par speed.  I'm not here to debate on the specs but the setting to boost my speed.  I already copied 5GB movie on all 3 WiFI access points to test and the slowest is 880L.  That is why I'm here to know on how to boost its speed if possible.  Thanks.

There maybe interferences or something faulting with your router. If your using single mode N on either radio and can't see 300Mb, then I would phone contact D-Link support and ask them about this. Let them know that your seeing 300Mb on other routers, just no the 880L.

Thanks for the advice.  But is there a setting to MIMO N  mode in 880L?  Or the MIMO would depend on the terminal that connects to 880L?
Title: Re: Maximum Date Rate of Wireless N
Post by: FurryNutz on March 27, 2015, 12:49:30 PM
Depends on the client side HW and what it supports.

Test single mode N, Auto Channel Width and WPA2/AES only and see. Test at about 6 feet distance.

Post by: nettewurk on March 27, 2015, 05:30:06 PM
How could I set to single mode N?  Do I need to disable the 5GHz SSID of 880L?

You can set single mode N on both radios...

Looks like SNB did a review and found the 2.4 throughput at around 147Mb

You configure single mode N ON the router under wireless settings.

Title: Re: Maximum Date Rate of Wireless N
Post by: nettewurk on April 01, 2015, 05:29:45 PM
Single mode setting means disable the 5GHz radio signal? Want to retain 2.4GHz since since most of my WiFi N devices operate at the lower frequency. Is this right?
Title: Re: Maximum Date Rate of Wireless N
Post by: FurryNutz on April 02, 2015, 07:03:16 AM
Both radios can operate on Single mode N at the same time.
Title: Re: Maximum Date Rate of Wireless N
Post by: nettewurk on April 04, 2015, 04:40:21 AM
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 (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.
Title: Re: Maximum Date Rate of Wireless N
Post by: FurryNutz on April 04, 2015, 07:05:08 AM
I wonder if thats a typo.
I see 600mb is listed here:
http://us.dlink.com/products/connect/ac1900-wi-fi-router/ (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.
Title: Re: Maximum Date Rate of Wireless N
Post by: FurryNutz on April 04, 2015, 09:00:37 AM
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.

(http://i.imgur.com/PLRFsBX.jpg)

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.

Post by: FurryNutz on April 09, 2015, 07:12:34 AM
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.
Title: Re: Maximum Date Rate of Wireless N
Post by: FurryNutz on April 09, 2015, 08:03:30 AM
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.
Title: Re: Maximum Date Rate of Wireless N
Post by: nettewurk on April 09, 2015, 08:27:11 AM
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?
Title: Re: Maximum Date Rate of Wireless N
Post by: FurryNutz on April 09, 2015, 09:21:28 AM
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.

Called yesterday but they simply told that there are many factors affecting the connection speed from interference from other cordless appliances, confirming first client adapter's MIMO N specs, security/encryption setting, etc. Did discuss what we had did exchanged a few days ago but difficult to understand with a Chinese accent seems irritated from the tone of her voice suggesting to look for another product.  Anyway, I'll continue wait fore the next F/W update, perhaps it might resolve these.

Ok so I got some info back. The 880L does support 600Mb on the 2.4Ghz radio. There maybe a typo or error in the information the Russian web page. Which that region doesn't apply to your region.

Looking at your actual regional D-Link support sources in the Philippine area, I don't see the 880L listed on there web site so I presume that either it maybe and the web page has not been updated or it's not listed on the web page as it may not be officially supported in your region.
http://www.dlink.com.ph/products/prodlist.asp?idCategory=285 (http://www.dlink.com.ph/products/prodlist.asp?idCategory=285)
If it's not officially supported in your region then you may need to return the unit to place of purchase as this may cause you some hassle with D-Link and there support policies later on down the road. If it is then you'll be ok. I'd ask them if this model is officially supported there in your actual region.

I hope to test the 880L out soon and see how it does connect on the 2.4ghz radio...

Any status on this?

I have connected my 880L to my 890L in bridged mode to the 890Ls 2.4Ghz radio. I presume it's connecting at 600Mb however I don't have a way to check the connection rate. I hope D-Link would re-add the connection rate feature back to there routers.
