Inspiron 15 3000 no 5g wifi

[Ieatbrains83]

Hey so I have a inspiring 15 3000 under adapter prop. It says I have a Qualcomm. Qca9565 802.11bgn am I wrong in assuming that should pick up the 5g signal my router is putting out. ? It will pick up the 2g signal. I know there is a 5g signal here my phone registers both bands labeling one as" routername"-5g the other just "routername" what am i doing wrong here peoples please help

802.11ac is the 5Ghz standard where as with 802.11n it's optional to have 5ghz. Seems like the big brands like Dell and HP are slow to add it. You could buy a usb adapter if it's necessary.

Your laptop's WiFi adapter evidently isn't a dual-band one, so it can only see 2.4GHz networks.

My laptop is the same so I disabled the built-in adapter and bought a dual-band USB one.

Yep. Your network card doesn't support dual band. So either live with the max speeds that your card can handle on the 2.4Ghz band or buy into and adapter for potentially faster speeds. Be warned though, if you are using your laptop in another room and have a couple of walls/objects and walls between your router and your laptop then you won't get better speeds on the 5Ghz band because it can't penetrate objects like walls as good as 2.4Ghz. That's the trade off unfortunately with the bands. The higher the band, the faster the potential speeds (limited by your ISP of course) but the less range and penetration ability. So take into account your location from your router first before buying into an adapter because if you are in a scenario where you will get worse speeds on 5Ghz compared to 2.4Ghz then it is going to be a waste of money. A good way to test this is to connect to your network with your phone in the exact spot where your laptop will be with you and run a speed test on both bands with the phone to determine if you will be getting anything out of connecting to the 5Ghz band with your laptop.

However, if you don't have 100+ megabit connection to begin with then it is kind of pointless to bother connecting to the 5Ghz band in the first place. Unless you are trying to share files across devices on the network with your laptop being connected via WiFi, then maybe there would be a use for it.
