I noticed that HP does not provide a Windows 11 Wi-Fi driver for the Intel(R) Dual Band Wireless-AC 7260 on the HP EliteBook Revolve 810 G2 support page. Since Intel has also ended support for this adapter, this could indicate a compatibility issue between the legacy wireless adapter, the Windows 11 Insider Preview build, and the T-Mobile 5G Gateway.

At this point, I'd recommend checking whether the same behavior occurs on a stable release of Windows 11 or, if possible, testing with a compatible USB Wi-Fi adapter to determine whether the built-in Intel(R) Dual Band Wireless-AC 7260 is the source of the compatibility issue.

Answer 1

Hi, good day!

To help me narrow down the exact cause, could you tell me

Does the Wi-Fi disconnect on both the 2.4 GHz and 5 GHz bands, or only one of them?

Are other devices connected to the T-Mobile gateway experiencing random disconnects, or is it only your HP EliteBook?

Does the connection stay stable if you connect the laptop to a different Wi-Fi network, such as a mobile hotspot?

In the meantime, you can try the steps below.

Open Device Manager, expand Network adapters

Right click Intel(R) Dual Band Wireless-AC 7260 > Properties > Power Management, then uncheck "Allow the computer to turn off this device to save power.

I look forward to receiving your update and I'm willing to collaborate with you till we resolve the issue. Do keep me informed by clicking "Add comment" below.

I noticed you reported my answer doesn't resolve the issue, and I want to make sure I answered your question completely and accurately.

Have you tried disabling the wireless adapter's power-saving feature?

A few more questions

Does this happen on both the 2.4 GHz and 5 GHz bands, or only one of them?

Is your T-Mobile gateway using a single Wi-Fi name (SSID) for both bands, or do they have separate names?

Are other devices connected to the T-Mobile gateway experiencing the same fluctuating signal or disconnects?

If possible, I'd also recommend temporarily moving the gateway closer to the laptop or to a location with a stronger cellular signal. You may also try moving your laptop to within a few feet (about 1–2 meters) of the T-Mobile 5G Gateway and use it for a few minutes. Kindly check whether the Wi-Fi connection remains stable or if it continues to disconnect and the signal strength still fluctuates between Excellent and Weak.
