Dell xps losing wifi connection
Hi !
One of my Dell laptops has problem with the wifi connection dropping several times every day.
Connection is reestablished easily by reconnecting to the SSSID manually , but it is annoying to be disonnected while surfing on the internet.
So , I want to know what causes the disconnections, and did some investigations & troubleshooting.
Until now, the troubleshooting has not fixed the problem:
- Installed different Wifi acces point and connected to this one. Problem returns on laptop.
- Changed IP settings on laptop to fixed IP address instead of DHCP client config.
- I installed latest driver for the wifi card.
- Installed the Intel wifi Proset configuration tool, which does not show any events about the disconnections.
- I installed Wireshark (http://www.wireshark.org/) on the laptop.
- Wired connection has no disconnections, only wifi connections is giving this trouble.
After being disconnected I did this troublshooting:
- On the laptop: run/cmd.exe / arp -a shows accesspoint (gateway) ip and mac address
- Pinging the gatway ip address from the laptop does not echo , no reponse
- In wireshark I can see ARP functioning between the laptop and the access point , exchanging MAC addresses.
- So there is a layer 2 connection between access point and laptop, but IP connection is not functioning (no ping reply).
- Window event log only show some DNS error after the disconnection, which can not be a cause but is a result of the problem.
What else can be done to fix these disconnections????
In picture you can see the wireshark log detail showing the laptop (intelCor) is receiving the gateway's MAC address (starting with 1C:3E) over the air.
At this point IP connection is lost, no ping response....

Removed Dell Stage Remote program from the laptop as it is broadcasting traffic on the network every second on UDP ports 10007 and 10019.
According to these remarks: http://www.shouldiremoveit.com/Dell-Stage-Remote-11386-program.aspx

JayJay,
Go to Drivers & Downloads enter your service tag number, then select your operating system. Under Network, download and install the latest drivers.
Try these tweaks....
Start, control panel, device manager. Click on Network and then right click on your wireless adapter, left click properties, power management. Uncheck the box, allow computer to turn off this device to save power.
Go to the power options, and changed the Wireless Adapter Setting, from Maximum Power Setting to Maximum Performance.

To avoid interference with other 2.4 Ghz networks in the neighborhood, I tried to configure the laptop to connect to a 5 ghz wifi network.
But the 5 Ghz (802.11-N) wifi network does not show on the laptop, although the Intel driver suggests it can support it.
See picture (Although text is in Dutch , English/US readers will be able to see that both frequencies are supported).
I upgraded the Intel driver to version to 15.8.0.0. (latest).
QUESTION:
Does the Intel Centrino Wireless 1000 N - card support 5 Ghz Wifi network connectivity?

Thanks Rick,
I applied both tweaks from your earlier post,
both the power save mode (uncheck) tweak as well as the maximum performance setting.

Which information from this network interface query could be related to the problem I posted?
