AC1750 Smart WiFi Router Model: R6400
Hardware Version: R6400v2

I bought this router two months ago? But suddenly two days ago the router's adapter caught fire and the router shut down. I bought a new adapter and the router is on but the lights are on and off. So I opened the router and saw that the IC was burned. So I can't find this IC and I don't understand the IC number. Will anyone help me? To purchase this IC, give a link to the Wave site?

That appears to be a 4558 series Op amp...

But the worse news is that a bunch of other stuff on the board is burned and it's possible you burned actual pcb traces too.

This requires the right tools and skills to fix...

This is a really low end router now.
I would look for a new one on eBay, or whatever you have similar in India.

Old topic, but in the signal path and with 16 pins, recognized this IC must be a variant of:

Qorvo RFFM4558A
5 GHz 802.11a/n/ac Wi-Fi Front End Module

https://www.qorvo.com/products/p/RFFM4558A

Seems really silly of them to put that 4558 marking on it, considering the opamp with same # is far more popular, historically.
