Samsung Galaxy J3 (2016)

[Anonymous]

I have a new phone (Samsung Galaxy J3, 2016) but it will only recognise one of my two wifi networks - 2G.  I have a 5G network that I want the phone to find, but I can't get it to recognise this, even when I manually type in the correct details.  What's going wrong ?  Is the J3 not capable of recognising 5G ?  Please help someone. Thanks.  B.

According to specs:
Wi-Fi 802.11 b/g/n, Wi-Fi Direct, hotspot.

802.11 a is required for 5ghz stand alone but the "n" should be both.

Thanks for quick reply to my post today. I'm not techie but from your reply I'm assuming you think my new J3 phone should find my 5G network ?  What does the "n" stand for ?  If I can't get my phone to connect should I get back to o2 as a phone issue, or is it a problem with my network ?  Sorry to be so ignorant - Help !

5 ghz networks are problematic on many devices. 2.4 is the standard that is most compatible.
It also depends on what channel you are transmitting on from your router as some phones won't see anything above channel 12, regardless.
Yes, in theory you should be able to see it on your phone, the "n" denotes compatibility with 2.4 and 5ghz networks, but theory is very different to practice.
If you can set your router to 2.4 only and just use that you shouldn't have too many problems.

Thanks for the explanation. I can now get on with 2G without thinking I'm lacking a better connection (although I wish o2 had been half as helpful with their advice as you have been) !  

Many thanks.
