[Q] Wi-fi N connection to Dlink DIR-655

I can't get my Note II to connect to my Dlink DIR-655 running in N-Only mode. My Blackberry Torch would connect and my laptop has never had an issue either. I have not changed anything recently and have been using this router with it's current settings for over a year without issue. The N2 sees the wi-fi network but, fails to connect once the password is entered (password verified). I can connect to other G mode wi-fi routers just fine.
DIR-655
Firmware Version: 1.35NA
Hardware Version: A1/A2
802.11n - Only
40MHz
WPA2 + AES
Anybody else experiencing this problem?

Hi 09GraySilverBusa
I have a DIR-825 and I had almost the same problem with my note 2 but I kept getting the reauthorizing problem. I went to dlink and posted there and the thing that finally worked for me was to change from AES to TKIP.
I have my 2.4 ghz band set at n and g
Auto 20/40 mhz
Auto (WPA or WPA2)
5GHz band is set to n only with all the other settings the same.
Hope this helps

Thanks but, I suspect your Note II is connecting via G mode. Also running in N only mode I can't select TKIP instead of AES. I'll try posting in the D-Link forum.

Tab Pro 8.4 connects to wifi on 2.4 and not 5, any way to get it to use 5?

I have a Netgear Knighthawk router and the main network is one name that utilizes both 2.4 and 5 and as long as the connecting device supports it, it should connect on that band.
My Nexus 5 and wife's S4 which are right next to my Tab are connected on the 5 band.
Any ideas on how I can force the Tab Pro to connect mm on 5?
Thanks

I can't remember in detail but I had mine connected to 5ghz but switched to 2.4 a while back.
If your tab can't see the network or is having a prob connecting to it, then enable broadcast if its disabled

Try changing the 5GHz channel your router is using.

My network only has one name but it is both 2.4 & 5 so when I connect its only one option.

I will try this, I have been messing with the channels for the 2.4 but forgot to do that with 5.
Thanks

If your using both 2.4 and 5 at same time, that might be your problem. Change the name of one of them. Xxxx5. Or something

I would really like to keep it as one network, I have had it like this since I set it up and have had zero issues. All AC devices connect to 5 and N to 2.4, this is the first time it may be an issue but my wife's S4 connects to 5 with no issues currently.

It seems your tab pro might be defective and not able to connect to 802.11ac, it can only connect to 802.11n which on your routher is running on 2.4GHz.

I had an issue with wifi one, for some reason it wasn't connecting right after some investigations. I enabled ssid broadcast and it worked again. I'm figuri g it was the rom being glitchy.
So try enabling broadcast if its disabled and see it that works

Tested out my Tab by connecting to my guest 5ghz network and tab connected fine. My router let's you combine the main network 2.4 and 5 into one name but guest network must be two separate names for the 2.4 and 5.

Are you sure that your guest network 5Ghz is running with 802.11ac and not A/N mode?

There are some incompatibility with tab pro and some routers.
I'm using tp-link wdr4600, 2.4ghz and 5ghz works fine. A friend, using different router, has the same problem as you, and sometimes the connection drops.

Have you loaded a ROM other than USA? I'll look for the link, or search for posts by me, but i had a similar problem with an S4, and it turned out to be some countries outside US use different frequencies that keep it from connecting at 5ghz. Just needed to change a couple of settings in some files and all was good, or load a USA ROM.

I haven't loaded any ROMS, running stock version that came with Tab from my US Best Buy purchase and I also did the OTA update.
I haven't checked if my Tab is running on N or AC when connected to my guest 5ghz network, I will have to check that soon. I will also need to find someone who has an AC network and a different router so I can test it out there, but I have a feeling this may be a little difficult for me to do.
Edit: So I checked my router and the 5GHz guest network is automatically set for a/n/ac and there is no option to change it. When viewing my Tab on the connected devices screen I cannot tell if it's connected as n or ac, how can I find this out? Any way to find this out via the Tab?

you can get a app called "network signal info" and install on your tab and other phones. in the app it can tell you what frequency you are connected at.

Tried that app out but all I could see on the statistics was that I was connected to the 5.something Ghz band, this was while I was on my guest 5Ghz specific wifi. I did not see anything about being "N" or "AC". Maybe I am not fully understanding this, but I thought AC was always in the 5Ghz band, is that not correct?

Unable to detect wifi network...!!!

I am using D-Link 2750U ADSL router, the issue I am facing is quite weird. My Phone, Laptop, Nexus 7 Tab can see Wi-Fi Network in range but Samsung Galaxy Tab 3 (10.1) cannot see Wi-Fi network. I tried connecting it manually by providing SSID, it says Network not in range. Interestingly, Samsung tab connects to Wi-Fi network in my office without any issues. So I am clueless as to where the problem is – is it with Router or Tab? Can someone help please

crash your router, try again
access your router, check your settings,history
try unsecuring your wifi, seemif it picks up, then resecure
tab does 80211 abgn, check you're setmfor wpa2-passkey
in your tab if always scan is enabled, toggle it
check system/etc/wifi/nvram* - if present
it's most likely the router and the tab.

Issue resolved (hopefully) by setting channel to fixed number rather than using auto option in router wifi settings.
Interesting aspect is my phone, which is also samsung (s4) and laptop had no issues.

@heeemz
channel!, Uhhh, weird,
My best guess is that you have a router with Full open channels like for Europe or Japan and that the TAB3 is an American version. So as American Wifi is not allowed to transmit on EU/Japan extended frequencies?

How to Broadcast Wifi on 5 GHZ band???

Hi ,
Has anyone tried to create a wifi hotspt via 5 ghz band on your Galaxy A50. When I try to create one, I only get 2.4 GHZ option. My two year old infinix zero 5 pro gives me an option to choose between 2.4 ghz and 5 ghz bands while creating a wifi hotspot. Sadly I dont see such options in my Galaxy A50. Is there any workaround for this? As per GSMarena.com A50 does support dual wifi bands.
Thank You.

I got 5ghz band wifi connection...my phone still can connect 5ghz wifi...i am using 505f

Thank yoh for your response!!!
But were you able to create a wifi-hotspot on a 5ghz band on your galaxy a50? If yes, how?

i have this problem with my gopro5...too bad don't connect

It normally works.
The Galaxy A50 can create a Hotspot at a frequency of 5GHz, but you need to enable the advanced setting of 5GHz. It normally works.
A505FN

how can i hotspot as 2.4 ghz from 5 ghz ?

I'm thinking of using my phone as a wifi repeater to use my pc. The wifi I get from the modem is 5ghz. When I make a hotspot from the phone, the wifi adapter connected to my pc does not see 5 ghz networks. Can I share this internet as 2.4 ghz from the phone?

I just realized that you can't change to 5Ghz unless you share it from your own mobile data. But i been trying something but doesn't really sure that it's working or not, the first things is you have to set your wifi from mobile data as 5Ghz then you can connect your n8p from your 5ghz router, here as my attachement in poco F4 says that my note 8 pro broadcasting 5ghz
