simultaneous dual band n900

[dethman]

i have a dual band n900 router (netgear wndr4700) and a dual band usb adapter (netgear wnda4100). they advertise 900mbps throughput (450+450 on each band)

is it possible to connect a single computer running Win 7 with a single wireless adapter to both bands and actually obtain 900mbps throughput?

or can you only connect to one band at a time and thus only achieve 450mbps throughput?

thanks.

It's an either/or. You'll have to pick your band and be limited to n450.

Welcome to the wonderful world of marketing. Pick and band, and hope you hit 450. If transfer speeds and throughput are what you're after, I suggest wired. Wireless is for conveinence.

..... and you will never hit 450Mbps on an n450 setup.

If your setup can consistently hit 150+, call it a day and be happy.

If you need more, go wireless AC (450Mbps is about what I got with ac1300) or wired gigabit.

Throughput does not mean functional Network output.

It means that Chipset inner work can run this speed.

It is like being surprise that I bought a 100 Horse Power car and see only 60 Horses in front of the car doing the schlepping.:hmm: - - :awe:.

yeah I only really get about 125mbps on my 5ghz network. was hoping to be able to simultaneously connect 2.4ghz to double it. guess not. LAME.

I highly doubt the adapter is simultaneous dual band. It is probably only dual band. Most client devices have a single radio that can operate in the 2.4GHz ISM and 5GHz UNII-I/III (sometimes -II as well) bands. Routers/access points usually have a seperate radio for 2.4GHz and one for 5GHz, so they can operate in both bands at the same time.

Some routers/APs do actually let you band the bands together when connecting to a similarly capable router/AP in bridge mode. It is uncommon though even in true concurrent dual band devices to connect to the same device using the same bands.

I guess lucky with my equipment. I can get 180Mbps 2.4GHz with my TP-Link WDR3600 and Intel 7260ac, and it is only 300Mbps "capable". I get 200Mbps on 5GHz (same room ONLY there of course). Just a lil' ole N600 router.

As for the advertising, it is misleading if you don't understand what it means. However, it isn't actually false at all.

It is almost exactly like a vehicle's horsepower rating, if you could see the dyno numbers while you were driving. A typical 200HP car is probably only putting 160HP to the road once you factor in gearing and drive train losses (which are tyically in the 18-25% range depending on the gear box and drive type).

In the case of wireless, you lose a certain percentage to forward error correction, beacon frames, lost packets and a few other things. Of course the further away you are, the lower your SNIR becomes and you drop in link speed.

The best of the best I have seen for link utilization is 224Mbps out of a 300Mbps connection, which translates to ~75% utilization, which doesn't include the fact that a few bits of that are getting taken up by packet headers and stuff, which actually makes utilization probably closer to 80-82% (this was/is with SMB file transfers).

That certainly isn't typical. I've seen other 300Mbps 11n setups barely hit 140Mbps, even when I KNEW there was no source of interference and I was close to the router/AP in question.

Different equipment is going to behave differently, and of course a noisy wifi environment or strong signal attenuation (or worse, both) will and can drastically impact what you can get.
