User connection cap / max with an Ultimate-N 6300 AGN

[DH1]

Hello,

I've been having an odd issue with my wireless card for a while now. A lot of the time, I can get my wireless to work fine, however, certain things seem make it cut-out: I have trouble connecting to public wifi networks (coffee shops, etc) and my connection at home cuts out whenever a certain number of my roommates are in the house. However, it doesn't seem to occur while on large scale corporate or academic networks.

It became very clear that it is a user cap issue because each time one of my roommates gets home, I get booted off a few seconds later. Over time, I realized that there seems to be some kind of user cap or something and it boots my wireless off the network when this cap is hit. It is only this computer though as it doesn't effect any other devices on the same network. Just to be clear, it actually shows that I'm still on the network, just with "limited" (i.e. no) connectivity.

I've updated and reinstalled the drivers with no success and I'm unsure what to do next. Any advice would be really helpful (perhaps I'll just buy a new wireless card). Thank you!

Here are my settings as an FYI:

802.11n channel width for band 2.4 -> Auto (tried 20 MHz as well)

802.11n channel width for band 5.2 -> Auto (tried 20 MHz as well)

802.11n Mode -> Enabled

Ad hoc Channel 802.11 b/g -> 11

Ad Hoc QoS Mode -> WMM disabled

ARP Offload -> Enabled

Fat Channel -> Disabled

Preferred Band -> No preference

Roaming Aggressiveness -> Medium

Transmit Power -> Highest

Wireless Mode -> 802.11 a/b/g

bobthejanitor7,

We understand you have uninstalled/re-installed and updated the drivers. Where did you install them from? Our first recommendation is that you check with your computer manufacturer in order to obtain the latest drivers from them. http://www.intel.com/support/oems.htm Computer Manufacturer Support - On Windows® 10, if this is the case, the Intel® Centrino® Ultimate-N 6300 is supported by this OS own inbox drivers.

From the configuration you informed:

1. Preferred Band -> No preference ( Set this to prefer 2.4GHz band ).

2. Roaming Aggressiveness -> Medium ( Set this to lowest ).

3. Set Wireless Mode -> 802.11 a/b/g according to the support mode of your router.

4. Optimize your connection as well by choosing a less crowded channel. Usually channel 11 and 6 are used by default by certain routers and most of the time these channels are croweded

5. Set your computer to work at maximum performance both on battery and plugged in: Control Pannel >> Power Option >> Set the High Performance to default. Also change Advanced Power Settings >> Wireless Adapter >> Power Saving Mode >> and set it to Maximum Performance.

6. Set the 802.11n channel width for band 2.4 to 20 MHz

As a second option, you can try the drivers in our https://downloadcenter.intel.com/ Download Center. *Please note that the drivers are Windows® 7 and Windows® 8.1 compliant, You can access the links below.

https://downloadcenter.intel.com/download/25510/Intel-PROSet-Wireless-Software-and-Drivers-for-Windows-7- Intel® PROSet/Wireless Software and drivers for Windows 7* - Flie name: Wireless_18.21.0_ s64.exe

https://downloadcenter.intel.com/download/25511/Intel-PROSet-Wireless-Software-for-Windows-8-1- Intel® PROSet/Wireless Software for Windows 8.1*- Flie name: Wireless_18.21.0_ s64.exe

1. Download and save one of the drivers above.

2. Go to Control Panel, Programs and Features and Uninstall "Intel® PROSet/Wireless Software", if it is installed. When prompted, choose the option to "Discard settings".

3. In Control Panel, Device Manager, Network Adapters, right click on the Intel® Centrino® Ultimate-N 6300 and Uninstall it. Make sure you mark the option to "Delete the driver software for this device".

4. Reboot the PC or scan for hardware changes, check device manager and if an older driver is detected and installed, repeat the actions to uninstall and delete it as well. Repeat this process until the OS does not allow deleting the driver, or until the controller shows as Unknown Device.

5. Install the Intel® Wireless driver. During the first steps of PROSet/Wireless installation, make sure to customize the installation and install all the 3 driver components

Hi Aleki,

Thanks for your help!

My computer is a Lenovo Thinkpad T420. I called Lenovo/IBM but since I am out of warranty, they are unwilling to provide assistance without pre-payment. I downloaded the drivers from the Intel download center (the ones you referenced above).

I just applied the settings you mentioned but alas to no avail. I'll try re-installing the drivers one more time and see if it works. Any other ideas?

Otherwise, I am stuck and will probably try buying a new wireless card (assuming it is accessible on my laptop). Much Appreciated!

bobthejanitor7,

Let us know how the re-instalation went so we can move into the next step. Regarding a replacement, Intel does not support integration which is when the original wireless adapter is replaced by another one. Please check this link for further information: http://www.intel.com/support/wireless/wlan/sb/cs-011644.htm Intel® Wi-Fi Products — Regulatory Information Regarding Hardware Installation or Upgrade - We recommend that you contact your http://www.intel.com/support/oems.htm Computer Manufacturer Support in order to check with them what other Intel® Adapters are compatible with your system.
