Router Making Hissing/Fizzing Noises

I have AT&T Uverse internet at home. I am currently connected and things are working fine. My modem is model number 5268AC (FXN)

Within the last 3 days, it has begun to make some strange noises. The noise sounds like hissing or fizzing. It's very similar to what my refriderator does in a cooling cycle sometimes. The noise is NOT high pitched, which is a common thing I've seen on Google. At first, I thought my refridgerator was going out. The modem is not excessively hot and there are no perceived issues other than the noise. Connection is steady and fast.

Now, I'm very concerned about my modem.

Any ideas on what this is and how to remedy this? I've tried calling support and was told there is high volume of calls, which I totally understand. I'm not sure how to get in touch with a technician or if it's even possible.

I am working from home in this crisis and can't have my internet go down.

Any help would be greatly appreciated.

No idea what you're hearing, but the gateway doesn't normally make any noise, especially noise you can hear across the room. If it were mine, I'd contact 800.288.2020 and request a replacement be sent.

Thanks... and I agree this piece of equipment is definitely not supposed to make noises.

I'll be calling first thing Monday to see what can be done about a replacement.
