I have a Netgear router that sets up two networks: a 2.4 GHz b/n and a 5 GHz a/n. I'm using WPA2-PSK [AES] and I have the right password. My 6.0.1 iPhone 5 connects to the 2.4 GHz network fine but "cannot join" the 5 GHz one; any ideas how to fix that?
By default, some routers will broadcast the same SSID for both bands, & your phone will automatically connect to the band with the best combination of signal strength, noise, etc. So, make sure you have different SSID's for both bands. After verifying that, on your phone, Settings>General>Reset>Reset Network Settings. Now see if your phone sees the 5GHz band & you can connect.
I've got 2 different SSIDs. If I do this reset, what else will get re-set (wiped) - what settings will I have to re-enter? I jut want to know what will be lost before I do this. thank you!
You will lose all saved WiFi passwords.
I have the same issue. Only restarting the router will allow me to connect to the 5ghz wifi. But the unable to join message happens the next time it tries to connect unless I restart the router again. Resetting my network settings never fixed the problem.
For me, the SSID for the 5Ghz band does not even appear in the wifi network (only the 2.4 Ghz band). However, my Ipad2 can see both the 2.4 and 5 Ghz bands.
I have reset the network definition in General and reset the router (a brand new dlink DIS-835 router) to no avail.
Can anyone help?
Forget to mention - iPhone 4 with IOS 6.1.1
Your iPhone 4 won't see the 5GHz band, as only 2.4GHz is supported.
The fix I found that works is to make sure that the SSID does not have a hyphen in it. Mine was like this, "Name-5G". Removing the hyphen from the SSID and making it "Name5G" allows it to connect. The only catch is you have to connect manually using the "Other" option. This was the only way we could get our 6 to connect to 5G. Seems like there might be an issue w/ connecting when there are special characters in the SSID. Good luck!
iPhone can't connect to 5 GHz router network
