Not all devices can use the 5Ghz frequency. It depends on what wireless network adapter they have. If they can not see it they can not use it.
It's a windows laptop, and it connected to 5Ghz fine until I followed the instructions earlier on in this thread to fix the Macbook - now the Macbook is fine but the Windows laptop will only connect to 2.4Ghz and not 5
The helpline at BT said it should just automatically connect to 5ghz but... it's doesn't!
Open Network and Sharing Centre then go to manage wireless networks. Highlight your 5GHz network and move it to the top of the list.
We have just been connected to fibre optic/Infinity ( after a titanic struggle with BT about costs!) -any way - all seems OK, but back to the problem of switching between 2.4 and 5.....so does the fix that ChrisSmith92 suggested work for Home Hub 5 as well - to fix the fibre optic at 5 for my MBPro?
Thanks for advice.....but BT wont acknowledge that this is a problem...!?
Apple devices seem to have a problem with the dual bands having the same SSids. Apple won't acknowledge that this is a problem. In answer to your question. Yes it will probably work, assuming you have the same problem.
If that doesn't help another thing to try is to change the Homehub to WPA2 only on both frequencies.
See link how to do this.
Thanks Chrismith92! I was getting crazy and now following your instructions I can work from home with my MacBook Pro.
