Connected at 450Mbps, and N dual-band router question...

Hey guys, so I can actually prove that one of my routers connected at 450Mbps, and isn't it true that we're supposed to be able to get 600Mbps connections once 802.11n was ratified by the IEEE, which actually happened without many changes at all.

I'd love to know what these "small" changes are, and why it took them *seven* years to put this baby to bed.

Finally, I have the Linksys WRT610N v1, with the May firmware upgrade. Is there any way to be able to connect to BOTH the 2.4GHz, *and* the 5GHz frequencies for even higher speeds? Such as the 600Mbps I read about somewhere. It's amazing how my girl's laptop is simply not affected at all on "her" band, the 2.4GHz one. lol...I downloaded a 10GB file just for the sake of trying this out. I can even work with Firefox with little to no difference in speed while downloading a massive amount of data. Wireless N makes *such* a difference. Amazing!

Thanks for any (technical?) help. What WiFi equipment do you guys have? I'm still a die-hard Linksys fanatic. D-Link is supposed to be killer, though!!

 

Impossible!

 

don't confuse mbps with mBps. Different speeds entirely.

 

As long as you use Intel WiFi Link 5300, then 450Mbps max since it has only 3 antenna connections for 3 spatial streams (3x150Mbps) at both transmit and receive sides. So, in order to have 600Mbps, it needs 4 spatial streams, which means it needs 4 antennas. I don't know if this kind of wireless adapter has already existed in the market, but certainly not WiFi Link 5300.

 

How can I get 450Mbps with my Intel 5300 card?
I can only get 300Mbps..

 

Does your router support 450Mpbs?

 

Thanks Greg.. that must be it.
My router only support max 300 Mbps.

I'm using TP-Link TL-WR941ND.
Is it possible with future firmware update this router will run on 450Mbps?
(the router runs on 3x3 mimo, but not dual-band)
Thanks in advance

 

Impossible nothing...I even have a snip shot of the speed, as I was as also surprised. I have the WRT610 from Linksys with the latest firmware (May '09), but it may have been an AVM router I used overseas. I don't remember.

Oh, and I just got my new Thinkpad, so the wireless card I used in my T60p is the Atheros AR5008X. I've not seen 450Mbps w/ the Intel 5300.

 

Is there even such a thing as a 4 stream router/wireless card at the moment? Last I heard a few months ago, 3 stream routers were only just entering the market.

 

I checked on some more info regarding the 802.11n standard, and it does talk about Max Throughput: 600Mbps.

Anyway, I found the snip of where I had said that I noticed reference to 450Mbps. See below. I had the 5350 card w/ WiMAX at the time, though. Did the damn thing use WiMAX "antenna" for the extra 150Mbps?

Thanks again!

 

Wireless N specifies 150Mbps for each antenna, to a maximum of four, so the highest theoretical connection speed is 600Mbps for wireless N. You need the hardware to support that, however, and I don't think there are any products available to the home user that use 4 antennas. So a network card can connect at 150Mbps and connect at full N speed, and your Intel card connects at 450Mbps it is at full N speed because it is 150Mbps for each antenna.

 

I have a wrt 600n and a wrt 610n with the 600adapter and the best I can get is 300mbps and that is within 15 feet of the router

 

Yes, correct. That's what you'd think...So in theory, 3x150=450Mbps. However, my Intel 5300 card is not connecting at that speed, but rather at only 300Mbps!?

I used to have the Intel 5350, instead of the 5300. With the 5350, I encountered the 450Mbps connection but once only. Hmmm...Could it be that the WiMAX (and also 3rd) antenna somehow connected to my DUAL-N Cisco router?

I also have the WRT610 with the latest firmware, and it rocks for sure. I'm in the same room as the modem and the router, but I don't think that's the problem.

I've always wondered if I can't somehow connect to both the 2.4, and 5.2GHz bands on the same computer with an extra N adapter (USB/PCMCIA/Express, whatever), or, with the 5350 (see above)?

 

That's because your 5300 is only connecting to 2 spatial streams wireless router (even though the router has 3 antennas, it doesn't necessarily mean that it's a 3 spatial streams wireless router).

5300 WiFi function is the same as 5350, which both capable of 3x3 spatial streams of 450Mbps.

Did you or do you have subscription to a WiMAX service? Your 5350 can only be functioning as WiMAX adapter if you have subscribed to a WiMAX service provider operating in your area. And if you did/do have, you would have known that WiMAX and WiFi function on 5350 cannot operate simultaneously.

 

So, if all it takes are three antennas, and gobs of routers out there sport 3 antennas, how come they all are being advertised as 300Mbps only versus 450Mbps?

 

The mere presence of 3 antennas is not sufficient to provide >300 Mbps connection rates. You also need a wireless chipset that is capable of supporting master mode with 3 or 4 streams. At the moment, no routers are available with such chipsets. Ralink and some others have recently introduced new wireless chipsets into the market for use by 450/600 Mbps routers -- sorry, didn't save the links -- so we'll hopefully see routers using these chipsets on the market by next summer.

 

Interesting. Never mind the 5300, or 5350, etc. Do you know of a USB N stick that will do the trick, or maybe one that fits into the ExpressCard slot? With 802.11n ratified, didn't the IEEE make some final adjustments, one of them being the possibility of 450 and 600Mbps?? I guess not, or we would have heard of it, huh?

WiMAX is a joke. Both Sprint and Clear aren't doing anything that could be construed as a serious deployment.

Thinking it might have been the 5350 that gave me the 450Mbps speed, was wishful thinking on my part, although it did display it...Hmm....

 

Summer? Summer???? Cisco and D-Link,...and Netgear, and whatever else DID know about the fact that it would eventually be a 600Mbps technology, no???

What about the so-called Dual-N band routers, such as the one I have, the Cisco Linksys WRT610? They just came out with a hardware refresh of that baby (WRT610v2), but there is no indication of anything in the sense of what I'm looking for...

Hmm...So again, those dual-N routers...two computers can simultaneously log on to "their" networks, both at 300Mbps each, and 300x2 is...ah, never mind that. lol

If I put my USB Linksys G adapter to use, will that help? This is all theoretical thinking obviously, but why not...

What say you guys about all of this?

 

Currently available dual-band routers won't get you 450Mbps or 600Mbps for a single connection. A transfer between any connected PC and the router will still be limited to 300Mbps (actually less, as the 300Mbps number refers only to the raw speed and not to the actual real-world rate with overhead & such -- which will be closer to 150Mbps).

 

i got that wifi card in my notebook; for connectin 450Mbit, ur router must work dual band-dual radio.

on wireless connections; 5Ghz for 300Mbit and 2.4 Ghz for 150Mbit, most routers can broadcast only one at same time but if u have dual radio router (not dual band, all of them dual band) u can connect it 5Ghz and 2.4Ghz at same time with 5350 and u may see 450Mbit speed.

 

hi yabani, what router are you using ?

 

Yes. That's exactly what I saw on another W700 that has the 5350 in it. This one doesn't though. Oh well, I figured it out for myself. Check this baby out.

NON-draft 802.11n goodies are coming our way shortly.
