    intel centrino advanced-n 6230 can't see 5ghz & speed for 2.4ghz only 130mbps


      I have 2 issues, please someone help me


      1. I just upgrade my wireless router to LINKSYS CISCO EA4500 (dual band) and i do have some issue not seeing 5Ghz on my wireless list (i have create SSID for 5Ghz and 2.4Ghz)


      My laptop has "intel centrino advanced-n 6230" wireless card and i believed this support dual band (2.4 and 5ghz) but i tried to set many things yet unable to see 5ghz in my wireless list - what could be the problem? (i used my ipad and im able to see 5ghz - so i know i setup everything correctly)


      2. IF i connected to 2.4ghz (regarless close to router or 20 feet from the router) i got 130mbps - i read from some forum people able to get 450mbps or 300mbps.


      ** i have update latest firmware for this software


      in my router i have setup Channel width (auto for 5ghz and 2.4ghz) and Channel: auto for both of them and has its own SSID


      Please give me advise what can i do so i can see this and also how can i improve my speed for my 2.4ghz as well


      Thank You in advance

          Hello owenintel,



          Thank you for your post. First in regards to the speed of the connection check the link below for recommendation on settings. Note that in the 2.4GHz spectrum there is the most amount of interference; in this case the speed would decrease. The maximum speed possible with this adapter would be 300Gbps.:


          What are the recommended settings for 802.11n connectivity?



          Now in regards to the 5GHz that cannot be detected by the adapter, most of the Intel® Centrino® Advanced-N 6200 adapters are capable of 5GHz, except for the 622BGHMW model. You might want to check with the laptop manufacturer if the laptop was designed for 5GHz support, for this support they would have needed to go through additional validation and installed a specific 5Ghz antenna.

            I just had this problem myself.  I just discovered I had to change the default settings in the device properties.


            Click start ---> right click Computer ----> properties ---> Device Manager ---> Expand Network Adapters ---> Right click Intel(R) Centrino(R) Advanced-N 6230 ---> Advanced Tab ---> Wireless Mode ---> Select 6. 802.11a/b/g.


            I don't know what 802.11A has to do with Wireless N, but that worked for me.
