I can never connect at anything higher than 270Mb/s with Wireless N. Even when my laptop sits 2cm from the router.

Also, even though I'm connected at 270Mb/s, the speeds that I get are around 2MB/s.

Is this normal? I've done all that is on that forum topic about acheiving a 300Mb/s connection but can't quite get there and the speeds are nothing like 270Mb/s either.

System:
HP Tx2z Laptop/Tablet (Wireless LAN 802.11a/b/g/n)
Windows 7 RC 64bit

Thanks.

Tried different channels?
And what's the brand of your network card?

[davevt31]

300 is the theoritical number, if your getting 270 thats pretty good.  Think of it has the MPG rating for your car, the number they say you will get is never the exact number you actually get.

It's a Broadcom 4322AG 802.11a/b/g/draft-n Wi-Fi Adapter.

The thing is, even though I'm connecting at 270MB/s, I get max transfer speeds of 6MB/s. Shouldn't I be getting over 20MB/s?

[Msradell]

Don't forget the transfer rate not only depends on your end of the connection of the other and also.  The other end could either be another computer in your own or over the Internet through your network connection.  The speed of each of these could and probably will be the limiting factor.

20 MB is also theoretical. You can be happy with 12 MB/s, there's quite some overhead on wireless.

It will be very difficult for you to get and maintain 20MB/s transfer speeds. In all my testing, i've only got around 10MB/s and that wasn't a maintainable number. Your 6MB/s is about what I see on average on a good day with no other wireless clients. Through the Win7 perfmon I see about double digits for throughput.

Even though the router will report your connection as 300Mbit, I can tell you that you will probably not see such throughput in your wireless network. One would think that a connection like that and you would be able to stream HD content flawlessly, but that's not accurate. The highest I can get without stuttering is 15Mbit throughput.

It's not entirely clear to me what DLINK means exactly when they mention the 300Mbit. All I have really seen despite the router reporting high throughput values, is 54Mbit-like connections in the real world.

If that 2MB/sec is from when you download from the internet, count your blessings.  That's quite fast.

Negative, through LAN. Using the Gigabit ethernet cable, I can transmit at around 30MB/s (due to limit of my DNS-323), but when I connect using wireless at connected at 270Mb/s to my DIR-655, I can only achieve 6MB/s.

So basically, this is normal speed for Wireless N? Bare in mind that my laptop and DIR-655 are within inches of each other.

[lizzi555]

yes, this will be the most you can achieve in the moment.
The Broadcom chipset in your Laptop is not fastest with the Atheros wireless in the DIR.

Due to that Broadcom chip you are also limited to 270 Mbps and not 300.

Few more Qs

- In the moment? Until wireless N proper drivers come out?

- Is the bottleneck is in my router or laptop?

- Is 6MB/s average speeds for wireless N?

Thanks

I hope they will release better drivers for the broadcom chipset which work better with other chipsets.

The bottleneck is between the different chipsets, not the router and not the wireless card.

6 to 10 MB/s is a good speed for a good 11N connection. This can vary and there is a lot that can affect a wireless connection negatively.

[ShMiCk]

Righty-O.

What are the average speeds for Wireless G? I read that it's around 2.5~3MB/s, basically 54/2 (2 way), then /8 bits.

[EddieZ]

Yes, that's the average speed.

This guide is what I normally go by for a reference



Comparing the 270mbps most brand new DELL latitude will show 270mbps for DIR-655 as there is where their chip sets max out at. Other brands will show 300mbps for chip shown in the top of the list. 120mbps is actually rated speed most of us are getting.

Since N is going standard in Sept 2009 so I take it firmware will be out for that.
