Linksys WRT300N 802.11n Router
802.11n ratchets up the speeds... if you're in a perfect environment

With the 802.11n draft standard complete, 802.11n based products have been showing up on the market from all the major players. According to the version 1.0 of the draft standard, 802.11n supports link speeds of 150 Mbps and 300 Mbps -- the devices tested by eWeek offered as much as 112.17 Mbps of real-world full-duplex traffic.

But while the performance gains over 802.11g products are quite remarkable, there are many caveats to this performance. For one thing, with the current draft standard, compatibility with legacy networks is a problem. eWeek's testing showed that performance of the Linksys 802.11n gear dropped to below 40 Mbps when legacy wireless devices were detected. The Linksys router tested also caused performance issues with legacy 802.11g devices even causing one router to drop its clients. And to top things off, 802.11n draft standard products are well over $200 for a router and accompanying client adapter -- that's a pretty penny for a product that is not even guaranteed to be upgradeable to the final 802.11n spec. From eWeek:

With this uncertainty in mind, it is not advisable to invest in these products lock, stock and barrel. Enterprise-grade WLAN manufacturers continue to wait for the standard to fully bake, and enterprise customers should do the same. Like the Airgo MIMO-based products we've tested during the last year and a half, draft 11n products should be considered only for highly specific needs requiring a fast wireless connection. And buyers should not yet expect the products to support the standard down the road.

Lawsuits

I smell lawsuits if these items actually degrade legacy wireless network signals. I for one will get pissed if this does happen, considering it will be a couple years before these items are priced reasonably.

According to FCC radio interference class protection policy, "This device must accept any interference"

That policy protects Linksys and all wireless vendors/chip manufacturers from lawsuits if the product is infact not compatible, does drop packets, etc.

If people are using wireless technology for mission critical tasks, they deserve worse than having clients dropped.

I hate how people throw around the term "couple of years" to try and make their point weigh more. These products could be reasonably priced and available in less than a year vs. 2+ years. If it isn't 2 or more years, its not a "couple of years"


Belkin MIMO Pre-N
By Ibrin on 4/26/2006 1:59:38 PM , Rating: 2
I own the Belkin MIMO Pre-N. I bought it for one simple reason. I have a mixed mode B/G network. My notebooks have G, but my wireless printer had B. Putting the printer online drug everything down to 11Mb/s. The Pre-N allowed everything to run at it's native speed. In addition, it happened to eliminate the dead spot I had in the house.

I don't have any Pre-N cards, and don't need the N speeds. If there is a G-class product with MIMO, it might solve this same problem. But, the Pre-N was the only thing I knew about. Early adopters should expect (and be used to) bumps in the road, Pre-N is no different.

I also have a Belkin Pre-n. I bought it for the increased range. It beats the hell out of my older D-link "Super G" router in both range and throughput.

Same here - pre-n is awesome - great bandwidth and great range. I don't see any reason to upgrade to the final-n.


Degradation of 11g networks was known

I'm amazed. Atheros told these idiots that there were severe issues regarding degradation of 11g networks and these bozos still pushed ahead.

Greed plain and simple. Hopefully someone will find a fix or you're basically going to have to rip our your 11g network and replace it because Draft N products may not play nice.

G is so susceptible to interference anyway. Anything near it's spectrum and it drops the connection. Perhaps it couldn't be avoided.

A lot of wireless routers have freguency ranges one can choose from (like wireless telephones). You may need to select a different frequency range.


Seems like another scam...

I made the mistake of rushing out and grabbing a D-Link MIMO router when they came out and upgraded to their "Super-G" speeds... what a mess! My generic MS G router was MUCH stabler and had twice the connection strength, though it was not as fast. But, if you can't keep a connection, what good is speed? Further, the whole point of MIMO was to have incresed range! Let me restate - it gets half the range of a generic MS G router!

I gave up and just keep it in G-mode, what a waste. Even with firmware updates it still drops transfers and clients - it's the most consistent thing it does do. And, I did swap it out for another one to no avail. The kicker is that they advertise the thing as backwards compatible. Which, for them, means that if you turn off the advanced speed features it is backwards compatible. It's Super-G or G/B - NOT both. In other words, it is not backwards compatible. *sigh* Why do they have to lie?

This seems like a lot more of the same. How are they supposed to get wide-area wireless broadband up when they can't even do it inside my house?

A: D-Link sucks, don't blame 802.11n. Every D-Link wireless product I've ever used has been utter crap. They make decent 24 port budget switches though.

B: Your experience on range flies in the face of mine and many others experience with pre-N stuff. See point A.

C: Wide area wireless broadband will not be powered by a $100 wireless router from Circuit City.
