Hi,
We have a broken Netgear wndr3400v2 dual-band wireless router. The wifi doesn't work correctly. We can see the wireless networks, however, every time we try to connect via the 2.4GHz bandwidth (for example, using wireless G), we can never access the internet / router. The router sees the device's MAC address but never assigns an IP address. If we try using a static IP address, it doesn't work. Wired works. I believe the 5 GHz band works but haven't checked.
Anyway, I have taken it apart and identified a component that I think might be bad. It appears kind of burnt, I'm having trouble identifying it though. It's next to the button that allows us to turn the wifi on/off. It's labeled on the board as U40. The device has printed on it, DF-J16. Here's some pictures. The front of the whole board was hard to get a good pic of. I can upload multiple pics in sections of the front if needed.
Can someone help me identify it please so I can try and find a datasheet for it? I was thinking it might be a BCW68F, package SOT-23 (we measured length and width of the chip and it seems to match the SOT-23 package size measurements).
