Installed the 6230 into a Dell XPS 15 L501X, replaced a Wireless-N 1000. Ping times shot to 400 MS and eventually the laptop disconnects, 6230 is also causing other laptops on the same AP to fail.
Reverteted to older Wireless-N 1000 and everything returned to normal.
Updated drives and uninstalled/reinstalled drivers, nothing corrected this problem.
Running Windows 7 64bit, connecting to Verizon / Westell SFU 9100EM configured with WPA
I had exactly the same issue with my new Dell, Intel N 6300 AGN wireless card. Kind of still do.
With WEP it connect to router just fine, but not with WPA or WPA2, all other laptops and smartphones connect without any problems using WPA.
It sounds very strange, but this is how I finally got it working:
After I had entered security key for wireless and it was trying to connect to router I changed Multicasting options on router to off. It does not matter whether I change it on or off, but at that very moment I was able to connect and can connected after reboot just fine as well.
I did more testing and uninstalled drivers and the issue occurred again (with Multicasting being off this time, as at first I I thought it was the reason), So I tried changing the setting once again when connecting and it worked again!
This does not make sense to me nor can I use such workaround anywhere else but home...
Sorry, I wasn't registered but I fixed my problem. So if this doesn't so on the support, will you repost?
I have AT&T Uverse with WPA2 and was not able to connect. I went into the router settings and removed MAC filtering. My laptop connected. I then enabled MAC filtering and my laptop disconnected. So I copied the laptop MAC address and put it into the "allowed" group. I have been able to connect ever since.
I have the same XPS15 laptop with the 6230.
Mine connects to the TP-LINK router but a lot of pings are slow and quite a few just timeout
I've tried the Advanced Enterprise Intel drivers but it didn't help.
If anyone finds the Windows update that might have caused this, please let everyone know
I might uninstall all updates to see if things improve.
After 45 minutes on the phone with 3 different Dell “techs”, they finally came up with an answer that my Centrino N1030 was a dual unit; didn’t believe them (it is not). Call Costco concierge to try and get a trustworthy answer, again 45 minutes went by, low and behold the Dell representative (seated halfway around the world) recommended the Centrino 6230. Again I didn’t believe the Dell techs. Found this site, after reading all the responses there’s no way I’m going to change to a 6230. Thank you all for taking the time to alert interested people. Regards, Ed
I have an L502X with the 6230 wireless card and everything seems ok. except for the fact that i dont get full performace out of the card. i have tried every power setting and all drivers. i have reinstalled all the drivers and the problem persists. I did discover that if i run windows 7 in safe mode with networking that the wirelss works great. im thinking its a problem with compatability of the card with windows 7 or other drivers in the l502x. ive contacted dell support and had to send them about 8 emails before i could get an actual person to email me back saying they will help resolve my issue. they have since replaced my wireless card with the exact same one. which obviously didnt work. i believe the only real solution to this issue is using a different card in the system which i suggested to dell and am still waiting on a response to see if they will give me a different card to put in my laptop.
Just in case someone else is searching and finds this thread, because I did when I was searching... the solution for me and my connection issues is as follows:
I found a recommendation to set QoS / WMM on my router to "Enabled".
For the E4200 it is under Application and Gaming / QoS / WMM Support = Enabled.
2.4Ghz speed jumped from 54Mbps to 270Mbps
5.2Ghz speed jumped from 54Mbps to 300Mbps
You may also want to enable WMM in the Device Manager / Network Adapter / Advanced-N 6230 / Advanced / Ad Hoc QoS Mode = WMM Enabled
I hope you are doing fine,
I registed to intel just to replay this post.
I had the same problem witth TL-WR1043N and I solve.
This what I did:
1) I upgraded to the last firemware version
2) I configure manual de WPA/WPA2. As always says recomend left settings in automatic I left that why but this time I change that I found the following message when I put the first try:
"We do not recommend using the TKIP encryption if the device operates in
802.11n mode due to the fact that TKIP is not supported by 802.11n specification"
So you do have to configure manueal with the protocol AES and your "Intel Centrino Advanced-N 6230" will work fine,
I hope you can solve your problems as I did.
