dual band USB Wifi adapter

Post by craig11152 » Wed Jan 18, 2017 10:14 am

I just "upgraded" my Comcast router/modem/gateway or whatever I'm supposed to call it. It has both a 2.4 Ghz and a 5.0 GHZ network. My phone sees both but my computers (one desk top, one laptop) only see the 2.4 because my Wifi cards are not state of the art.
Its not a big deal because my desk top is hard wired with ethernet /cat5 and the laptop use doesn't need the faster speeds.....

BUT

I see these USB Wifi adapters that suggest I could make use of the 5.0 network if I stuck one in a USB port.
Out of curiosity does anybody know if they work well? And more importantly if I plugged one in would my 5.0 network suddenly appear as an option?
As it stands on my cell phone I see both the 2.4 and the 5.0 networks and can log in to either but on the computers the 5.0 network doesn't even show up.
Would installing the right USB Wifi adapter magically make the 5.0 network show up?

Beware that the only way you can get full use of the 5GHZ spectrum over USB is if you're using a USB 3.0 adapter on a USB 3.0 port. If either is only 2.0, your theoretical cap is at 60mbps, and realistically that number will be considerably lower. In other words, your connection speed will be comparable to what you can already get on the 2.4 GHZ spectrum.

Your best bet if you want to take full advantage and if your PC doesn't have USB 3.0 ports is to use one of your PCI expansion slots and buy a PCI card. Beware though they're kinda pricey, ranging from $60 to $120. Search Amazon or ebay for AC 1900 PCI.

My experience, at 2 different rural residential locations with 2 phones, a tablet, and 3 laptops, is to continue to utilize the 2.4 GHz 802.11 connection. It talks further, and more reliably.

First and foremost, the speed delivered by the carrier at each occasionally bursts to about 50 Mbps, but is consistent around 20-30.

Second, #1 is insignificant, as the serving sites rarely move that fast. Even YouTube takes a minute or more to download a 200 m TV show. What good is an ultra-fast connection to the curb, but not so fast out into the cloud? I mean, I have 1 Gbps cat 6 Ethernet too, but I don't move data that fast on that either. Do I need faster, and am I willing to give up the range (below) to get it from the few sites than may be able to deliver it?

Third, I find the connection quality, given the same router and the exact same device, about 1/2 as good at 5.8 than 2.4......the RF field strength is about half as good. Wooden houses, etc. Did a lot of testing with that.

Fourth, although okay for some location-changing uses like my phone or a laptop, anything important that I do with lots of data (desk computer or 4K UHD TV) is done over Ethernet anyway.

I think you might find some advantage in apartment or condo environs where there is a lot of 802.11 use and (for the time being) not so much said use at 5.8 G......but given the RF penetration and quality I'm seeing, not so much. You may also have data-moving tasks between devices on the same routers that may also be improved at 5.8, but......really?

Equipment at both locations is ASUS RT-AC66U router, new Panasonic Toughbooks, Samsung Tab S2, and Samsung S7 edge.....so I don't think it's an equipment problem.

Personally, I think that internet service beyond the 20-30 Mbps I'm seeing consistently on speed tests is pretty much a waste of money until the rest of the 'net' and all the important serving sites can deliver data faster than that.

I bought a cheap 5ghz usb 3.0 adapter off eBay and I wasn't impressed at all... Half the time I have to put my finger on it in order to make it load webpages. I use 5ghz on my phone as well, shaves a considerable amount of time off app updates. I never move that far from the router so the diminished signal strength isn't a big deal to me.
