Title: How to get Wireless N speeds?
Post by: mco on January 28, 2010, 09:00:39 PM
Just installed DIR 655 (A4 model; NA 1.32 firmware).  With exception of Shareport (topic for a different day), router works largely fine.  Curious issue though.  I have 2 older laptops (a 2yr old Dell Inspiron, a 1 yr old Acer) which both show up as connected with Wireless N and speeds >>54Mbps.  My new Lenovo x301 (Windows 7 64 bit, Intel(R) WiFi Link 5100 AGN) won't do better than 54Mbps.  I have played around with a lot of different settings based on various posts on different fora incl. this one but can't seem to get it to work.   Diagnostics (below - 1st line is mine) that access point is of unknown type.  Maybe has something to do with this?

List of visible access point(s): 10 item(s) total, 10 item(s) displayed
        BSSID      BSS Type PHY   Signal(dB)   Chnl/freq    SSID
-------------------------------------------------------------------------
00-26-5A-B4-1C-3B   Infra    <unknown>-21      1    my network
00-1C-DF-3B-E3-FB   Infra    g   -82      6    K-Town

Any ideas for how to get this to work are welcome.  Kind of sad to have bought a N router with USB connection for harddrive, etc and all I can use is G router with no USB connection so hoping I can get this solved at least so I have something to show for my $$ spent on this.

Did you read the sticky on how to get N speeds? It's at the top of the forum.

I ran into this last night. In my case, the router was set to wireless n only and the intel adapter wouldn't connect at all.  When I switched the router to mixed it worked at 54 mbps.

A little research turned up that if you have the router sert to wpa-2 aes/tk.. it links at 54mbps.  If you set it to only aes, then it works fine.

You will however, need to delete all of your network profiles on the other machines and create new ones.

Hope this helps

Thanks.  I missed the sticky.  I'll give this a go.  Unfortunately I have an older wireless print server that may not support the encryption settings required to get N speed.  May have to choose between speed and printing.   Oh well. 

Editorial....  After having spent hours getting new router and computer set up and working reasonably well with printers, harddrives, Blackberry, etc I must say I am disappointed in how hard it is to get it all to work even for somebody who once upon a time wrote operating system level code.  If somebody figured out how to make computers and related devices easy to understand and use together they would make a fortune.  Or - maybe there is more money to be made selling hard to understand and hard to use stuff?

Check you Device Manager adapter settings for WiFi Link 5100 AGN.

Mine was set, by default, to 20 MHz. I had to change it to auto.

 I am about to give up on this.  I have reset encryption, adapter settings, etc.  Darn thing still only connects as wireless g at 54Mbps.  Router is fine as I can get my other computers to connect at higher speeds.  Got to be something with the PC/adapter.

Thanks.  Just not doing it for me - although I have not tried to set the router only to Wireless N.  I need to run in mixed mode n/g due to other devices that aren't n compatible.   I find it curious though that when I look at the output of the adapter diagnostics in my original post it claims that my network/access point is of "unknown type".  When I look on the router status page it says the PC is connected as wireless G.  When I look at a little Lenovo Access Connections tool or hover over the windows network symbol it says the network is of type wireless N.  In all cases though 54Mbps is reported as the connection speed. Maybe an issue w the mixed mode after all?  Will check.  Other ideas welcome as well.

what happens when you force N only mode on your intel adapter?

have you checked for updated drivers for the adapter?

Thanks. I have latest driver so that's not the issue.  Any idea how to force n connection on the adapter?  I can't seem to figure that out.

Got this solved.  See how in separate posting.  Thanks all!
