Hi, I have Intel centrino Ultimate-N 6300 wireless card, but it works only 54Mbps speed, Drivers are latest from intel support site, in device manager I see only a/b/g mode. Where is wireless N mode gone? I update drivers, configure my router: (Linksys E1000) if I leave only N mode, I cannot connect to router at all with wireless...

Somebody can help me?

reboot didn't help

[idata]

Wow!

New driver, Thanks, I will try

Did you install the wireless card on your computer yourself?

This card has 3 antenas.

I guess your router got some problems too. Would it be the faultness of the DD-WRT version?

Is there a 32bit driver version? I could not find can you help me? I use Windows 7 32bit.

Did you install the wireless card on your computer yourself?

No.

I guess your router got some problems too. Would it be the faultness of the DD-WRT version?

It can be. I think I need try to connect another computer with wireless n card to check the router. It's no new DD-WRT firmware version.

Is your computer a Dell one?

[idata]

Thank You!

Yes, I have Dell Latitude E6410.

First time after installing windows I installed drivers from Dell support website. I tryed to update them, but this didn't help too.

This thread says his Intel Centrino Ultimate-N 6300 card was not compatible with Linksys E4200 Router, got the same trasfer speed of 54Mbps.

[idata]

You have tried version 14.1.1.0 drivers and it didn't help?

[idata]

Yes, now I installed version 14.1.1.0 drivers, but speed still only 54Mbps

[idata]

So I need another wireless network card?

[idata]

SAD! It should be the problem of the router.

[idata]

How far is it from Notebook to router?

http://www.intel.com/support/wireless/wlan/sb/cs-006205.htm Intel® WiFi Products — Power Save Polling (PSP) causes connection issues with some access points

If you change 802.11n channel width for band 2.4 from 20MHz only to auto, does it work fine?

[idata]

Though the end result is the same, different manufacturers are using different methods to have the user pick their 20/40 channels.

·Recent builds of DD-WRT have you choose the 20MHz Control channel and by specifying whether the Control channel is the "upper" or "lower" portion of the 40MHz block. You may need to toggle between upper/lower to unlock the channel you wish to use.

·Some stock firmwares have you choose a Main and Aux.·It wouldn't surprise me if some had you also choose a main and then the center frequency of the 40Mhz channel.Channels are specified by their center frequency but instead of displaying (center of main 20 MHz + center of additional 20MHz) the devs opted to display it as (center of main 20MHz + center of 40MHz).

Thanks PudgyOne, I've tryed these settings, but still no luck... That number (54Mbps) is driving me crazy...

The router is 1 maybe 2m from computer.

When changing channel width for band 2.4 from 20MHz only to auto, working fine.

So which setting I need choose?

channel set to either 1, 6, or 11?

Advanced Settings

WMM is required to be on for any Wi-Fi Alliance Certified N product. By default WMM is already on but many users disable it which may prevent N rates or lower throughput.

I haven't tried a DD-WRT firmware yet.

[idata]

Is it your router a v1.0 or v2.0?

You could try a 4MB flash DD-WRT.

Not N draft 2.0
