My wifi signal has gotten worst with every firmware update, I think. I don’t know why I didn’t noticed before. Maybe it is because its the 5Ghz that is the worst, but also the 2,4 Ghz drops signal strength from it goes from -48 to -60. on firmware 1.03 and up. So I went back to ver. 1.00 and suddenly the wifi signal was the best ever on the 2,4 Ghz, but also the 5Ghz has improved.
I did a few short test every firmware with Acrylic WiFi Home and with my laptop apro. 10-15 meters away  from the router in my house.

I would really like to use the lates firmware, but not if gives me this pure signal. Maybe DLINK should test the firmware better? Well I don’t know why the 890L deliver such pure signal, with the latest firmware, but works well with ver. 1.00. On all other firmwares the 2,4 GHz band strength is -60 -62 from where I was was testing, but with 1.00 I was -45-48

Ver. 1.00


Ver. 1.03


Ver. 1-06


Ver. 1.07


Ver. 1.08


Ver. 1.09


Ver. 1.10B07

hmm... since FW 1.00 does not work well with my 890L, iphones can not connect to 5Ghz and have troubles with 2,4 i'm back with 1.10. Maybe I need another router  . The FW 1.00 did seam to have the best WiFi signal strength compared to all other firmware version on the 890L

I previos had a linksys wrt 1900acs, but it rebooted frequently, so that did'nt work as well.

DLink 6555 VS Dlink 890L on 2,4Ghz band.... 
655 almost as god as signalwise as the 890L

What are some sample captures with SC enabled?

What is the distance in between you and the router when you capturing this?

Might try FW from the EU region to see if there maybe any differences since you are in the EU region.

I know from what I was told that Broadcom had introduced some bad wireless behaviour in the Smart Connect feature a while back thus SC was broken. Not sure if there was more to this as well.

I've only seen bad behaviour in an early FW version and have not see issues since then with my 4 iPhones and other wireless devices along with my 2008 Mac Book Pro which is getting old now. I have had two 1300Mb AC class bridges online at the same time streaming my DISH tv service to my two Joeys. Two NEST controllers have been nothing but stable. I've even seen some good speeds with my new DWA-192 adapter:

Bar some initial setup issues I had.

FW 1.10 with SC on, connectet to 2,4Ghz measured at same distance/place as before, 15meters from router. Difference between FW 1.00 and all other FW are signal loss of -10db to -20db on the 2,5Ghz band. I think thats a lot.


No improvement with SC on I think.

There was some issues with the broadloom drives, not sure if things were really resolved or not. This maybe something we need to contact D-Link support about and let them know.

[Blueyed1]

Well, the firmwares I have tried was from this ftp: ftp://ftp2.dlink.com/PRODUCTS/DIR-890L/REVA/ for the first testing, is that US?
When using the update feature of the router, I would asume that it downloads fw from eu?

Did a quick test with EU FW 1.01, 1.02, 1.06, 1.08 and 1.09… signal strength are similar to the test with US FW. FW 1.01 gives the best signal on 2,4Ghz and 5Ghz.
EU ftp://ftp.dlink.eu/Products/dir/dir-890l/driver_software/DIR-890L_fw_revA_1-09_eu_multi_20160512.zip

Stopped as FW 1.09 EU for now,

[FurryNutz]

Yes ftp2.dlink.com is the USA FTP site.

Yes I believe the update feature of the router is regional and should find updates from the EU region for your region.

So those versions you tests from the EU site are having better results than from the USA site?

[Blueyed1]

No. There is no differens in signal strength in the firmware from eu site. They are doing as good or bad as the eu firmware.
Theres is some differens in FW version numbers and sizes. FW version 1.01 EU deliver the same really good signal as 1.00 US firmware.

I wonder is DLink has turned down the signal strength of the 890L in all other fw versions on purpose?

[FurryNutz]

Anything is possible...may have been turned down my the WiFi driver Mfr, not D-link.

[Blueyed1]

Maybe its the Wfi driver?
I wonder what to do get better WiFi signal stregnth. To me it looks like the 1.00 US firmware and the 1.01 EU firmware has a better signal strength in my setup, all other firmare versions delivers a lower signal strength. Not that I really want to, but I am tempted to try out the DD-WRT firmware for the 890L, but it may be risky?

[FurryNutz]

There is code with in the FW that comes from Broadcom and other 3rd party Mfrs depending on which chip set D-Link uses. In this case, Broadcom is the Mfr.

Would be worth a try for DD-WRT and see. You can always revert back to D-Link FW. Just know that WRT maybe using same drivers. 

[Blueyed1]

I have written to DLINK, but not with high hopes  but I have to try that, before doing DD-WRT, since I dont know what to do

[FurryNutz]

Let us know how it goes. I would try phone support for more immediate information.

[Blueyed1]

The answer from support was to install FW 1.11, but it it just as bad as all other firmware versions but 1.01.
New test 1.01


Test with 1.11


About FW 1.11
On the EU FTP there is 2 different FW 1.11 they are also different in filesize 19.565KB and 19.441
ftp://ftp.dlink.eu/Products/dir/dir-890l/driver_software/

On the US support site the DIR-890L is named DIR-890L/R and on the US FTP there is 2 folders, with different FW contens
ftp://ftp2.dlink.com/SECURITY_ADVISEMENTS/DIR-890L-R/REVA/ 19.590KB
ftp://ftp2.dlink.com/PRODUCTS/DIR-890L/REVA/

The new FW 1.11 that I got from dlink support "DIR890LA1_FW111b01.bin" has filesize 19.593KB.

So none of the FW 1.11 has the same filesize  .

Ya, I wish D-Link wasn't so regional. To many differences especially with it comes to devices that are globally sold.

Only think I can think of is that they may have had the power up at one point then were made to back it off some here. Or the change came in from Broadcom and D-Link has nothing to do with it.

I would pass this back to D-Link support if you can with your results.
