does anyone else have trouble connecting to dual band? - G2 Q&A, Help & Troubleshooting

in multiple places I cannot connect to 802.11n 5ghz dual band networks. I can connect to 2.4ghz networks though. tried at work and at home and both places I'm unable to connect. looks like it tried, then just gives up.

Try to configure different ssid for every frequency.

[Q] Wifi N

Hi,
I have a UK Desire Z. The spec says the phone is capable of connecting to b/g/n wifi standards. However I am having trouble seeing my N network on the wireless list. Has anyone sucessfully connected thier phone to an N network?
Are you trying to connect to a 2.4hgz network or a 5ghz one?
It should work on the 2,4 but not on the 5 ghz
I have dual-band router and Desire Z does see/connect to 2.4GHz N network. It does not see 5GHz network. But my 5GHz is running in two channel 40MHz mode, didn't have time to check if switching to single channel would allow Z to connect.
Mine connects fine to my home Wi-Fi network, which is 'N' standard. Not sure what speed it is connecting at, or whether it's dropping back to B/G though.
Do you have MAC address security blocking set on your router, and if so have you told it about the phone's MAC address?

This verifies that answer, changing to single channel on 5GHz will not make a difference.
The wifi radio on the DZ is a 2.4GHz radio.

[Q] 802.11n Issues

Is anyone else having problems connecting to an 802.11n network? My 802.11n network will not show up under networks. I've got no problems connecting to my g network, but cannot connect to my n network.
I've tried disabling all security, 2.4ghz and 5ghz and resetting the router with no luck. Network is working fine on my laptop and desktop.
I've tried using wifi analyzer and still nothing.
Any suggestions?

Can't connect to 5Ghz WiFi on Galaxy S4 I9505

I have a i9505 S4, it does not seem to be able to find the 5gHz network whereas on the iPhone 5, i am able to connect to the 5gHz network. Both 2.4 and 5 gHz network have different SSID names.

Change to different channel in 5ghz and try, 36 or 44 channel.
5G wireless

Me too, I9500 no issue with this, but I9505 can't search for 5 Ghz wireless network, chg router channel still the same. I 'm using Netgear R6300.
Same issue here
I had i9190 and it was working great. Now I have tried two i9195 and one i9192. Both i9195 only work on 2.4Ghz and do not show 5Ghz bands at all. I9192 could not connect to any network, DOA. All phones had 4.2.2 update so it was not software issue. I guess samsung started to block 5 Ghz band on i9195.

[Q] Automatic switch frequency band from 2,4 to 5 Ghz

Hey,
quick question: Does anyone know of a method to switch the frequency band on the Nexus 4 based on location or SSID?
Maybe via App, Tasker, profile or whatever? I would love to use the 5Ghz band at home, but work only runs on 2,4. If I use the automatic mode it only connects to the 2,4 frequency band of my router.

I am using 5GHz. Check if your AP has a separate MAC address for 5GHz and connect to that SSID and you should have no problem connecting.

Actually you're right. There is an option to separate both bands on different SSIDs. Guess I missed that option... thanks for the hint!

oneplus 6t 5ghz wifi

My oneplus 6t has issue in picking up the 5ghz signal from my router. It always connects to the 2.4ghz band when i go farther from the router but never switch back to 5ghz band. To put it simply, when i go to balcony, the 5ghz signal is very weak and onplus 6t is automatically switching to the 2.4ghz band but when i come back into the living room (where the router is), my 6t doesn't switch back to 5ghz. Hence slow speed and its kinda annoying. Is there any possibility to force my 6t connect only on 5ghz band.
note : my router has the option of disabling the 2.4ghz band but i cant do that because few of the devices are old and only have 2.4ghz band.
On the router you could set up one access point SSID using onky the 2.4 frequency and a separate SSID using only 5 GHz. Connect older devices to the first one and your 6T to the second one. My ASUS router supports this kid of thing; Netgear router I had before would do this also.
I'm not aware of a way on the phone to only use one frequency.
