Not getting 300mbps on N600 WNDR3400v3

I have searched and searched on these discussion boards, and everything tells me that the speed of my router (N600 WNDR3400v3) doesn't get to the advertized 300+300mbps that it says on the box. Right now, I have a modem that, when plugged directly into it, I get the 150mbps that I pay for through xfinity. Connecting the modem to the router, and then wired in via ethernet to the router from my computer. I'm only getting 90mbps. I did a factory reset to get it to that speed. Am I missing something simple with the settings or something that would prevent me from getting the 150mbps? I've updated the firmware and power cycled it multiple times. 

 

Thanks in advance for any insights into this.

As per the WNDR3400v3 Data Sheet "Five (5) 10/100 (1 WAN and 4 LAN) Fast Ethernet ports with auto-sensing technology" as well as the fine N600 Wireless Dual Band Router Model WNDR3400v3 User Manual p.12 "Four local area networks (LAN) 10/100 Mbps Ethernet
ports for connecting the router to your local computers.", p.106 Internet connection, ..., Port speed 10/100 Mbps Autosensing ... there are only Fast Ethernet ports (100 Mbit/s) - so the total Internet traffic you experience (100 minus some protocol overhead) is about all what you can expect.

 

The 300 Mbit/s wireless PHY rate would allow slightly more over the air under ideal conditions, while concurrently talking to the Internet and multiple LAN ports, but it's more a theoretical number.

Thanks for the reply. So if I understand correctly, when I'm connected to the router and getting high speed internet, the 300mbps is saying that the router can handle, say 5 devices, each downloading at like 50mbps or some ballpark number like that. It doesn't mean that I should be able to do a speed test and get the max speed that I'm paying for up to 300mbps. Is that correct? 

 

I feel like that is a little misleading on netgear's side if that's the case. I guess you still have to read the fine print to know what you're actually buying.

Well, I'm not Netgear. The max Internet data rate is 100 Mbit/s (minus some protocol overhead) on this router. No way to see 300. Similar, each LAN connection can't exceed 100 Mbit/s, so again, same limitaiton. Marketing wise, the router is promoted as N600, this does translate to 300 Mbit 802.11n on 2.4 GHz and 300 Mbit/s 802.11g on 5 GHz. Each wireless can reach some more than the 100 Mbit/s, e.g. for talking to multiple devices on the LAN and/or the Internet concurently. Afraid, that's it - and yes, I had to check the documentation, too.

The original WNDR3400 dates back to 2010. It was never a powerful router and the technology has moved on a lot since then. For a start, they phased out 100BASE-Tx LAN and WAN some years ago.

 

Your wifi speeds also depend on the clients you are using.

 

Then there is the fact that wifi standards are just that, standards rather than anything you will see in the real world.
