Wireless Internet forum: Intel(R) Centrino(R) Advanced-N 6250 AGN won't use n band

Nope, not a dell. It's a Toshiba Satellite M645-S4050. I DL'd the most recent version of the driver from the Toshiba site(although the windows check for updated drivers and said it was good). So I went from 13.1 to 13.3....without effect. I'm still connecting on g.

Is there a way to tell it to connect on n?

D-link: DIR-628
most updated firmware from the dlink site 1.24NA
I tried setting the router to 802.11n only but while my computer could see the available connection, it couldn't connect.

This is what I copied from the status page from the router:

Wireless Radio :Enabled
802.11 Mode : Mixed 802.11n, 802.11g and 802.11b
Channel Width :40MHz
Channel :6
Secondary Channel :2
Wi-Fi Protected Setup :Enabled/Configured
Security Mode: WPA Only - Personal

I don't know what other information you need. Other computers can connect to this router as n. just not mine for some reason. I can't find a place to set my adapter to use n only

The OEM Intel drivers by default install the "Intel(R) Centrino(R) Advanced-N 6250 ABG" adapter instead of the "Intel(R) Centrino(R) Advanced-N 6250 AGN" adapter. You can verify this by going to Device Manager. To resolve this issue, download the latest Intel drivers in zip format and then do an update drivers and manually select the AGN version.

Your router setup is not compatible. I find it disturbing that no maker is offering online courses in networking. Even when it comes to how to select the router wifi settings they fail.

Here I have spent too many posts asking for the router settings and it's becoming clear that folk DO NOT WANT to become IT GURUs. They want it to work, right out of the box.

Over in the Cnet Networking forum we tackle this a lot. But it does require folk to reveal the settings, make, model, version, firmware versions and by now you get it that folk do not want to work that hard.

But do try it the Cnet Networking Forum way (see the stickies.)

We have the answers but we need the details.

When they can't try the methods that our techs use. We send them out with setup notes and space PC-Cards and usb wifi sticks to sniff out if some card has gone south.

There are those that try far too hard to fix an onboard wifi card. Since we charge by the hour we could try to save some cranky card but I'm sure the customers would start talking bad about us if we racked hundreds in service fees like that.

I realize this thread is several months old, but apparently his problem is still evident. My machine is an Asus G73JH-BST7 running Windows 7 Home Premium and sports an Intel(R) Centrino(R) Advanced-N 6250 AGN built-in wireless adapter w/WiMAX. My router is a DLINK DIR-855 which is capable of generating wireless g/b/n at 2.4GHz and 5GHz simultaneously. For quite some time I battled with the same issued mentioned by several in this thread. All other machines connected without issue to wireless n (including my Mac Book at 5GHz respectively). The Asus would "see" the SSIDs (wireless signals) at both signal ranges and even prompt for the security key when attempting to connect. However, the connection would fail with an error message generated by Windows that the SSID could not be found and prompt the user to use the builtin network troubleshooter which also did not provide any viable solutions. I wanted to exhaust all possibilities before upgrading the firmware on my router. I tried removing the security protocol from the wireless; changing the g-signal to n-only; resetting the router to manufacturer defaults; running Windows updates; checking Intel updates for the wireless adapter; uninstalling/reinstalling wireless drivers; reinstalling the OS using the Asus restore media; disabling all other wireless devices accessing/not accessing the network...and a host of other troubleshooting approaches that are too detailed to name. The solution, in my case, was a firmware upgrade on the router. It was sold to me brand-new using revision 1.02 (This revision supported using the shareport for a 3G wireless adapter. All subsequent firmware upgrades removed this capability which is why I was hesitant to upgrade the firmware.)I upgraded my router to the latest firmware revision 1.23NA as of April 1/2011. I reapplied my original router settings manually. The Asus connected to wireless-n without a hitch. Perhaps someone can offer an explaination regarding what changed and why this worked and hopefully my scenario will help others.

I applied this exact fix on my machine. Switched from TKIP to AES in the router setup, and my Dell E6410 connected via N instead of G.

Same Intel wireless card, but the router is a Netgear RangeMax NEXT WRN834B v2 with firmware version V2.1.13_2.1.13NA.

Moved to a wnr3500 (hope that's the model) and all good.

Yes, I'm using the suggested settings from the CNET Networking Forum sticky.

I know this thread has been dead fo quote some time, but I have the same issue with my dell precision that has this wireless card in it. I have went to advanced settings on the device and enabled 802.11n mode, changed the width and prefered band, but when i go to "wireless mode" at the bottom of the list, it lists everything up to 6.802.11a/b/g, but there is nothing in that list that has "n" in it. When I go to connect to my network it shows that the routers radio type is 802.11n. Any ideas? It is a rosewill rnx-n4ps router. The device in device manager is listed as Intel(R) Centrino(R) Advanced-N 6250 AGN and I just installed the latest drivers from intels site. Thanks!
