Apart from telling us very little useful information, this isn't the best place to ask for help with a router.
You have posted your message in the section of this community given over to Mobile Routers, Hotspots & Modems. (This is easily done, given Netgear's complicated community structure.)
Many questions apply to different types of device, so you might get responses here, but these devices are very different from your router, so you might get more help, and find earlier questions and answers specific to your hardware, in the appropriate section for your device. That's probably here:
Feed in your model number and check the documentation for your hardware.
You may have done this already. I can't tell from your message.
I mention it because Netgear gave up on supplying paper manuals years ago and people sometimes miss the downloads.
If you do want more assistance, you can help people to help you by providing the information suggested in this forum's header:
Subject (Include model number and brief summary) Model (Recommended - Helps the community give the best answers) Body (Include additional detail including model version, firmware, OS and environment where relevant.)
