Channel Width? Only supports 20/40/80Mhz. Not sure what 140 is.

Make sure you disable Smart Connect which will bring up more options for each band.

Are you talking about the wireless channel?

Yes, i disabled smart conect, i have 2 wireless network, one with 2.4 ghz and another with 5 ghz. The problem is when i leave the room where is placed the router,the signal is very bad  and i have only 80 square feet. The devices are disconnected continuously from 5ghz, it jumping on 2.4 ghz but same problem, very very poor signal, and all devices that i'm use are loosing the conectivity with the router. (Model Name: DIR-879   Hardware Version: A1   Firmware Version: 1.07)

I seen on another dlink router, that i can change the Channel Width from 30-140 on 5hz, and on 2.4ghz the channel from 1-14, curently my router is on auto, but on manual i can only select 4 channels. I gues, probably, the firmware is diferent, it has the same interface, i didnt remember the serial number of that router, it was black with 4 antena. 8)

I read about the wireless channel, that it might be interfence in my home, i scaned with an andoid aplication named "wifi analyzer" and the app it recommend to change the wifi chanel between 130-140 for 5ghz and channel 12,13 or 14 for 2.4 ghz.

What do you think guyys? my firmware is for europe, WITH WHICH FIRMWARE CAN CHANGE THE CHANNELS ???:o :o :o :o

Wireless devices will be regional since they have different rules and regulations regarding what channels can be used.  Keep the Channel Width on auto but change the channel to a clear one. Auto is the best since the router will find the cleanest connection. If you lock the Channel Width (different than channel) to 80MHz, then you will lose a bunch of distance. Auto is the best (or 20/40MHz).

For 5GHz, are the only channels you can select 36-48?

What devices do you have?

Also, try moving the router to a more central location. Is there a lot of wifi interference? Is the router near large appliances?  Mirrors? Fish tanks? The range should be much better with this router.
