Centrino Wireless-N 1030 not connecting at 300 mbps with linksys E4200

[LCrev]

My Wireless-N 1030 of my laptop works at 300 mbps when conneted to the D-link DIR-615. Great! BUT i cannot get more than 54 mbps when connecting to the my new Linksys router E4200. When I set the E4200 to Wireless-N only, it doesn' connect at all.

However when using the Linksys AE1000 adapter instead of the intel 1030 it connects on both frequencies (2,4 and 5 Ghz) at 300 mbps.

Why is the Centrino 1030 not compatible with Linksys wireless-N?

What happens when you disable the bluetooth in the adapter

Does the speed increase?

BT was disabled.

Enabling and disabling doesn't change speed.

I have the same problem just different router (Netgear WNDR3400v2). According to this link, you should be able to set the 5G settings for your wireless-N 1030 adapter:

http://www.intel.com/support/wireless/sb/CS-030709.htm http://www.intel.com/support/wireless/sb/CS-030709.htm

Problem is I can't find the setting for 5G but according to that link, it applies to our wireless N 1030 mini-card:

PropertyValue802.11n channel width for band 2.4Auto (not in 20 MHz only)802.11n channel width for band 5.2Auto (not in 20 MHz only)802.11n modeEnabledFat channel intolerantDisabledRoaming aggressivenessMedium (or less)Throughput enhancementDisabledTransmit powerHighestWireless mode802.11a/b/g802.11n channel width for band 5.2Auto (not in 20 MHz only)

This setting does not exist so I am confused as well. If your adapter has this setting, change and hopefully it will work. It says its a Wireless N adpter so unless Dell sold me something that will never connect to N, I am confused how it will ever work.

Indeed you won't find the 5 Ghz channel in the 1030 settings, because the 1030 is a single band adapter. The centrino advanced-N 6230 has dual band and the same driver as the 1030. Hence the settings for 5GHz band.

It seems the 6230 has a similar problem !

Just remember that I connect my 1030 with the D-link wireless router DIR-615 on wireless-N at 300 Mbps.

Where is the difference ? linksys wireless-N vs d-link wireless-N vs intel wireless-N ???

I saw that the D-link DIR-615 is compatible on Intel's compatible list PDF (I tried to find that PDF again but couldn't locate it). I may just go ahead and take back the Netgear WNDR3400v2 (not on the compatible list, but WNDR3300 is btw) and get the DIR-615 instead. Sorry, I don't want to hijack this thread but thought there might be some comparible issues / resolution.

I did see for the 6230:

/message/146180# 146180 http://communities.intel.com/message/146180# 146180

I found a recommendation to set QoS/WMM on router to "Enabled".

For the E4200 it is under Application and Gaming / QoS / WMM Support = Enabled.

2.4Ghz speed jumped to 270Mbps

5.2Ghz speed jumped to 300Mbps

So I guess the related links that show up to the right of my post after I made it were of excellent help, although the one I clicked was not my adapter or router, the suggestion still applied.

I have seen a LOT of issues with the Advanced-N 6230 with no solutions... I suspect this solution of enabling WMM in QoS will solve many of these issues.

Hi waterbound,

Fantastic, the WMM did the trick! Thanx m8.

The WMM in my E4200 was disabled because of trouble with the upstream VOIP priority. I couldn't imagine that this WMM was related to the wireless-N !!

(default for WMM in E4200 is enabled)

Now i have wireless-N 2,4 Ghz at 300 mbps with intel 1030 and linksys E4200 router.

Problem solved.

Nevertheless i will look for replacing the intel centrino 1030 with a 6230 with dual band (5 Ghz has less interference)

Gr,
