My Linksys WUSB6100M isn't detecting my 5GHz wifi signal, only the 2.4GHz

One day, my usb adapter stopped connecting to my 5GHz wifi signal. I started manually trying to connect it but it didn't seem to work. Do I need a new usb adapter because this one is faulty?

Not sure about the full scope of what you attempted via "manually trying to connect" (e.g., wired connection perhaps).

However, in any case, more information is needed.

Make & Model USB adapter? Does it feel overly warm or even hot? I have had a couple fail on me and the "heat" is often quite noticeable.

Do other wireless devices use/detect 5 GHz?

I would start by downloading the applicable wireless adapter drivers and reconfiguring the adapter as applicable to your wireless network.

I have checked all my drivers and they seem to be up to date. The usb doesn't seem to be hot or warm. All other devices in my house are detecting the 5Ghz signal fine.

Do you have any other 5 GHz network devices you can temporarily relocate to host computer's location. Could be interference.

Try using an USB extension cable to move/raise the USB adapter up and about. Adapter may be degrading and just no longer as sensitive as it once was.
Get the adapter clear of wires, furniture, and other possible sources of interference.

Try another known working USB adapter if available: borrow from another computer.

Try the existing adapter on another computer.

Determine if the problem stays with the current computer or follows the USB adapter.

My wifi router is downstairs so that might be the problem. If you would like to see my adapter I can send a picture to you. I've borrowed a wifi card from someone for a day and it could detect the 5GHz wifi signal, so I think it might just be my adapter.

try your adaptor to a pc located as close as you can do it (i.e. use a laptop turn internal Wi-Fi off use the WUSB6100M to see if you can see 5ghz, it is possible distance is the fault, possible the WUSB6100M needs to be changed as well

 

[anthonyseptic]

I have tried this and it still didn't detect the 5Ghz signal when I was right next to it.

 

[The Paladin]

time to get a new one then

In agreement with The Paladin.

Those adapters are made as inexpensively as possible with little or minimal QA.

Your efforts so far very much seem to narrow the problem down to being the adapter.

Do recommend that the adapter make be the same manufacturer as your router if at all possible.

Otherwise the differing manufacturers will just blame the other guy....

Rip. Well it only lasted one year so it must have been a shitty one. Maybe I'll just get a wifi card
