Hello all, I am looking for some guidance on the optimal router configuration. A few months ago I purchased a new router, Netgear N600 (model WNDR3400). For internet service I have the 20 mbps from Time Warner Cable. My internet speeds have been extremely slow, so I went out and purchased a dual band adapter for my laptop. After installing the software, I did a speed test and I'm only getting 4-5 mbps. I shut off the built in wifi on the laptop and am only using the adapter and this doesn't help. When I plug the network cable directly from the modem to my laptop, I'm getting the 20mbps.
I logged into the router but don't know enough about the configuration so I didn't want to adjust anything and screw it up worse.
For what it's worth, these devices are configured for wifi:
PS3 (gaming or Netflix)
Please let me know what additional information I can provide.
Thanks for your help!
