Only Power & Internet LED's are on

[Bellpsych202]

Recently lost router connection.  Modem is working properly, but on router only the power and the internet LED lights are on.  No other lights.  My laptop has no ethernet port so can't plug modem or router directly into computer to perform some of suggested troubleshooting options. Have also tried to reset the router by using the reset button on bottom.  Unplugged and replugged everything with connectivity and rebooted. 

Currently connecting to my home network via iPhone hotspot which is recognized as a network.  My regular home networks are no longer listed.

SOS  Is my router just DOA?

Details:  Netgear N750 Model=WNDR4300V2  OS=WINDOWS 10 64 bit

X380 Yoga Laptop (ThinkPad) - Type 20LH (I have 2 thinkpads-no desktop or tower computer - neither one has an ethernet port and I do not have an accessory adapter)

Any assistance is very much appreciated!

The reset button/hole has to be pushed in for 10 or more seconds while router is on. Did you do that?

Your model is getting old, I'd look for a more recent and supported router.
