SL510 can't connect to 5GHz N network

Question

I have Thinkpad SL510 laptop and DD-WRT flashed Netgear WNDR3300 router. The laptop can connect to the N-network when it is running at 2.4GHz but when I switch to 5GHz N-network, the laptop does not see it. Is it because SL510 does not support 5GHz or I have a problem with my configuration? Laptop is running 64-bit Win7 with all the updates installed. I am using the Lenovo wireless tools to connect to find and connect to the wireless networks.

Answer

Not all wireless network card supports 5GHz.

The following network card that supports 5GHz N network are:

  • Intel Centrino Advanced-N 6200
  • Intel Centrino Advanced-N 6205
  • Intel Centrino Advanced-N 6230
  • Intel Centrino Advanced-N + WiMAX 6250
  • Intel Centrino Ultimate-N 6300
  • Intel WiFi Link 5100 AGN
  • Intel WiFi Link 5300 AGN
  • Intel WiFi Link 5350
  • Intel Wireless WiFi Link 4965AGN

 Legacy or low end wireless card or router would not support 5GHz N network.
