Just got the router and set it up...
On the 2.4ghz side, I'm set up on the cleanest channel (per inssider) which is 6, channel width is auto (although I've tried it fixed at 20 also), N-only, and security is WPA2 personal. WMM support is enabled. I'm running firmware 1.0.02
The laptops continually stay around 72mpbs, occasionally jumping to numbers in the 100 range... twice I saw it actually hit 144. Inssider shows the max rate as 144, while other N networks in range are as high as 270. I'm sitting right next to the router with 5 bars -- why is the max rate 144? Why won't it run at 300?

Here are the available networks....
I guess I didn't realize that to achieve 300mbps you had to use 40mhz, which means you're using 2 channels simultaneously.
The laptop I'm currently on does in fact have an intel wireless adapter... I changed the settings for the adapter from 20mhz only to auto, but it's still the same... I'm assuming because the router is still only chosing to run at 20mhz... Is there a way to force the router into 40mhz mode?

I found another one of your threads and found my answers:
I guess even with the other weak networks around me, it might be more detremental for me to run 40mhz... I could live with 144, but it's still odd sitting directly next to the router and only seeing 72.
I hope my 450mbps trendnet usb adapter sees better results when it comes in. I will test everything with file transfers as well, as I realize the link rate doesn't necessarily have anything to do with actual throughput rates.

So with my old G only network, I was ftping files wirelessly from my laptop to my HTPC which is also connected wirelessly at an average rate of 1Mbps.
With the E4200, my test laptop connects to the 5ghz radio consistantly over a 200mbps link rate (currently at 270). My HTPC is still connected via my old ASUS router/bridge running on the G network. I was seeing an average of 2Mbps... when pulling from my HTPC back to this laptop, I was actually hitting 2.75mbps quite often. **note -- this isn't the same laptop I was using in my above posts. Anyway, there seems to be a big difference
The trendnet 450mbps usb adapter I mentioned earlier will replace the 802.11g bridge, so hopefully when that comes in, the next test will result in even better transfer rates.

I read all the threads about the 144Mbps limitation on the E4200 and the explanations about interference and stability. I understand that there is a trade-off.
BUT why does CISCO advertise the E4200 model as "Transfer rates up to 300 + 450 Mbps speed for a premium home network experience" if it can NOT achieve a rate above 144Mbps?
I`m far from pleased and this can be called false advertising.
Where am I worong?

^^ Because under IDEAL conditions it is possible to connect at the rate. However, you will be FAR from ideal and never achieve those rates. Remember whatever you connect at the wireless speed, you will only transfer data at 50% of that rate (on a good day with a tail wind).
