Dell XPS L502X Wireless Adapter Problem

I recently bought a Dell XPS L502X system and have been using it for around 2 weeks, until this problem suddenly came up.

First of all, the network connection was lost during a MSN chat. I tried to restart the computer, but it takes a very long, stuck at 'Logging Off' screen for more than a few minutes. So I manually turned it off (POWER button), and since the next restart, I notice the Wifi indicator on my laptop was gone, and I was never able to connect via wireless.

1) From the Intel My Wifi Technology utility, it says 'No supported Intel wireless network adapter was found'.

2) Then I run the Manual Diagnostics Tool from Intel, and it straightaway fails the first test, Hardware Test. Error message being 'Driver version does not support Intel PROSet/Wireless WiFi Software version 14.0.1.0'

Here are some of my system info:

OS Name:                   Microsoft Windows 7 Home Premium
OS Version:                6.1.7601 Service Pack 1 Build 7601
OS Manufacturer:           Microsoft Corporation
System Manufacturer:       Dell Inc.         
System Model:              Dell System XPS L502X
System Type:               x64-based PC
Processor(s):              1 Processor(s) Installed.
BIOS Version:              Dell Inc.          A01, 15/02/2011

In the Device Manager -> Network adapters, these are the active devices

- Bluetooth Device (Personal Area Network)

- Bluetooth Device (RFCOMM Protocol TDI)

- Realtek PCIe GBE Family Controller

Does this look like a hardware problem (that I need to revert to Dell warranty), or some system settings that have been possibly corrupted?

Please advice and help.

Thank you.

eeehw,

 

Can you run the Finding System Information Tool and post everything back here.

Thank you so much for the quick response.

After posting the above problem, I was giving another try on system restoring to an early point of yesterday.

It starts nicely afterwards, with the Wifi fully functional as usual. The only thing weird was in the Intel My Wifi Technology window, it shows 'Disabled', though I am having a successful wireless connection to my ADSL router and the internet.

However, bad thing happens after a while. It simply drops out on its own. The Wifi indicator is gone (although pressing Fn+F2 still seems to toggle, but there is no actual Wifi function running) and all wireless connection is again dead. Same thing could happen after every reboot. Wifi being alive for a while, before drops out on its own (even if I disabled my router to have no actual internet connection).

I am now quite sure the hardware is fine (or at least it runs for a while).

eeehw,

 

Did you try pressing F2 to see if the wireless adapter is turned on?

 

I would try contacting Dell Tech Support. I do not see the wireless adapter listed in the log. You can look in these places to see if your Connection is enabled, but from what I'm seeing, even if it was turned off, it should show in the log.

Here is the system info I've got after reverting to a previous restore point.

Surprisingly, it now has the wireless adapter listed!

By the way, I don't see the status of wireless adapter status after pressing F2 during boot-up.

I had the same problem since I got my laptop, same specs XPS15Z L502X.

Based on my experience, wifi connection dropping is not the problem, as you noticed on your System Information or Device Manager, wireless adapter disappears. Which after it disappears, you can't reconnect to wifi even if you try using "Troubleshoot Problems". I thought it was also the windows update affecting it, did a system restore before updates, still not working. Updated wifi adapter drivers, still disappears. Did a full factory reset couple of times, thinking it was a virus or malware, but to no avail. Not caused by anti-virus or firewall too, tried changing different anti-virus programs.

Tried these options:

1.  FN+F2 = only turned on or off bluetooth ( wifi adapter disappeared in device manager)

2. enabled wifi adapter manually = can't find adapter

3.  disabled then enabled wifi adapter = won't enable or disable (adapter not showing )

Quick fix to this is a full restart for the laptop, but its an annoying thing to do over and over everytime it happens. Can't figure out what triggers the wifi adapter to not work.

What is this so called hardware problem?

I've trying to get sell to replace it for months. I'm under warranty and everything, but they keep trying to trouble shoot it instead of fixing it. What can I do to hold dell accountable. Make them have to fix it.
