Network adapter will not connect to 5G wifi

[Robinoz]

This new computer is fitted with a Realtek Network adapter (802.11b/g/n) that picks up my ISP's 2g Wifi connection but will not pick up the 5g connection.

It seems that the network adapter is not up to the task and I wonder if there is an updated driver for it or whether I should have it replaced. I've tried numerous solutions to get it to connect, but have been unsuccessful.

Any help appreciated.

Hi:

That model wifi adapter is a single band card only.

You can replace the card with this model if you want dual band AC...

Realtek RTL8821CE 802.11 ac 1x1 WiFi + Bluetooth 4.2 Combo Adapter (MU-MIMO supported) HP part # L17365-005.

You can find this model on eBay, or Ali Express,

The card will have the same 72 MBPS throughput as the RTL8723BE on the 2.4 GHz wifi band, but on the 5.0 GHz wifi band, it will have a max throughput of 433 MBPS when you have an AC router with an excellent wifi signal strength.

Thank you for your prompt and detailed answer Paul.

I bought an ASUS laptop for my wife at the same time as I bought my HP and perhaps should have simply bought two ASUS products which were slightly cheaper, but have a touch screen and a better Network adapter. I didn't think I needed a touch screen. Such is life.

I'll go buy a new adapter.

You're very welcome.

Yes, I find it hard to believe that HP is still installing single band wireless N adapters in notebooks. when we are now onto AC and AX dual band wifi speeds.
