Have just loaded new N600 router and cannot view or connect to the 5ghz network, only the 2.4ghz. Have tried to locate on 3 x diff laptops. Why would this be? No use to me unless I can get dual access (the reason for purchase!), as will keep dropping out (like last router) on the one bandwidth.
I’ve tried 4 x diff laptops now. Some irony here, as the latest one I tried, is the oldest - 7yrs old - and it recognised the 5ghz network! The one I really want to get hooked up to the 5ghz network is a Toshiba L650-04k, only about a year old. It has a Broadcom 802.11n adapter, model BCM94313. How do I check if this adapter is compatible with 5ghZ? Why aren’t all recent adapters compatible!! Bl**dy pointless buying a dual-band router if most the hardware out there isn’t compatible anyway??
From what I know, this has less to do with newer or older, but probably price and performance. I’ve got two laptops – from around the same time frame.
1. The HP $400 laptop uses an older Broadcom – that when I Googled it – didn’t mention it was dual-band. (And when it doesn’t, it should be assumed it is 2.4GHz singleband).
2. The Samsung ultrabook use an Intel Centrino Advanced-N 6235 – which when I Googled that shows it to be a dual band chip – and indeed I can see both wireless networks from the one laptop.
3. And like I mentioned earlier, the family’s Apple products seem to come with both bands.
I also have a 7 year old “brick” of a Fujitsu laptop that was built for gaming (was very pricey when I bought it). And, it, too, sees both wireless networks.
It’s a valid point…the old laptop that views the 5ghz was top of the line at the time, with 17" screen etc…will just bite the bullet and purchase a usb plug in adapter…
