Intel Centrino Wireless-N 1030 card does not see N network

Hi,

My new laptop (Asus N55SL) has a built-in wireless-n 1030 adapter. I'm using a Netgear DGND3700 Dual-Band router which is already being used by a few devices (via the g and n networks) so I know my router is working fine.

Both wireless bands are broadcasting their SSID.

My new laptop does not detect the n network. It can see the g network fine. I've even tried manually adding the n network with no result.

I've checked adapter properties and they are set as the following:

802.11n Channel Width for band 2.4 - Auto

802.11n mode - Enabled

Ad-Hoc channel for 802.11b/g - 11

Ad-Hoc QoS mode - WMM enabled

Bluetooth AMP - disabled

Fat channel intolerant - disabled

Mixed mode protection - CTS-to-self Enabled

Roaming aggressiveness - 3. Medium

Transmit power - 5. Highest

Wireless mode - 3. 802.11 b/g

I think the last 2 are for when I wish to use my laptop as a wireless station (?).

Everything looks like it should be able to connect to an n-network but it can't.

I'm using the latest wireless adapter drives from Intel.

Laptop specs are:

Windows 7 HP w/ SP1 x64

Intel i5 2450M (2.5Ghz)

6GB of DDR3 RAM

Hi Chris,

Note that the Intel(R) Centrino Wireless-N 1030 is a Single-Band card, where will only connect to a 2.4ghz Network.

If your Netgear DGND3700 Dual-Band router is broadcasting Wireless-N on the 5Ghz spectrum, then the card would not be able to even see the SSID at all, and this explains the behavior you are seen.

We would recommend either contacting Netgear* and see if there's a way to change the router's setting to broadcast Wireless-N on 2.4Ghz spectrum.

Cheers!

Thanks for the clarification. My router supports Wireless Network (2.4GHz b/g/n) upto 145Mbps but I only seem to be getting 54MBps at 2.5Gh/z via the wireless adapter.

Can you confirm what max speeds I should be getting from my wireless adapter?

Chris,

The speeds on the card would vary, depending on the integration from each OEM, however you may want to try the following:

1. Have the most current driver from the OEM manufacturer

2. Set router to 20/40 Auto channel width, mixed n/g

3. Turn on WPA2/AES encryption, not TKIP

4. Enable WMM and QoS on router

See the following URL:

Data rate will not exceed 54 Mbps when WEP or TKIP encryption is configured

Steps 1, 3 and 4 are confirmed.

Not sure if my router supports 20/40 auto channel width. I'll look into it and report back.

Hi mailto:Stitchz@intel Stitchz@intel

I saw your response to Chris, which said that the N-1030 was not dual-band. That is very helpful

 

information as it explains a problem I was having.

To be honest, I thought any adapter that support 802.11n was dual-band by definitiont. Apparently I've learned something.

I was looking at the product specs for the N-1030, (http://www.intel.com/content/dam/www/public/us/en/documents/product-briefs/centrino-wireless-n-1030-... http://www.intel.com/content/dam/www/public/us/en/documents/product-briefs/centrino-wireless-n-1030-...) and while it states support for 802.11b/g/n I don't see where it says anything about single vs dual band, or 2.4 vs 5 ghz.

So, I guess my question...as I look for WiFi solutions, what should be I looking for in the specs to be assured that it can operate in both bands?

Thank you,

Brian

Buy a laptop that has the "802.11a" or "802.11ac" on their specs. For example, the Intel Centrino Advanced-N 6205 has this specification: 802.11a/b/g/n. If you see the letter "a" before "b" it means it has 5 GHz capability. follow this thread for more information: /message/220265# 220265 https://communities.intel.com/message/220265# 220265
