Dell :: E6400 Intermittent Wifi Connection

Apr 9, 2009

I tried a quick search but didn't come up with anything...

On my e6400, once in a while the wifi connection is intermittent and drops out for 10-15 seconds, comes back for a while, then drops out again. This doesn't happen all of the time, but is happening now as I type this out with it on my lap.

I'll admit I haven't really tried to diagnose. This has the following wifi card:
Dell Wireless 1510 802.11a/g/n Draft Mini Card

Dell :: E6400 Intel Wifi 5300 Dropping Connection

Aug 15, 2009

I reinstalled Vista 64-bit Business on my laptop. And I've installed all of the drivers which are working, but my wifi drops out every 20-30 minutes. I've done some research and found this isn't uncommon...

so I installed the lastest Intel drivers, disabled all of the power saving features on my wifi card/DCP.

But, it still disconnects! What the heck!? I might have had this same issue in Windows 7, but I can't really remember. All I know is that when I tried to back it up using WHS, it would always fail.

Dell Latitude E5440 :: Intermittent Power Connection To Docking Station

Dec 16, 2014

I was given a Dell Latitude E5440 and a docking station for my work.  I brought in a wireless mouse and keyboard that I use for input (the reason for mentioning this will become evident later).  The computer and dock were NIB and are ~ 2 months old.  I have a Dell external monitor plugged into the dock via a DVI cable, and use it as a secondary monitor.

One thing I noticed early on with this setup is that the interconnection between the computer and dock is 'flimsy', at best.  If I move the computer/dock on my desk by sliding it around, I lose connection and the external monitor image disappears.

My current issue is related but a bit different, I think.  On 3 separate occasions in the past couple of weeks, the notebook screen has gone black without warning and the system has shut down.  Once I was able to get the system back on, I was able to determine that the cause was that the battery had drained to 5%, and the system had shut down.

What I find odd is that this has happened while the unit is on the dock.  What is even more odd to me is that, apparently, while the notebook has lost power connection to the dock, the video connection to the external monitor remained in tact.   That is, in fact, the main reason I did not notice that the battery was draining.  That, and the fact that I was never shown a warning that the battery was getting low and I should find an outlet.  So, only the power connection pin or pins of the dock appear to be affected.  This happened last night when I left for home.  I had not touched the computer all day, since I have the wireless keyboard/mouse I mentioned above, but I did shut the lid to put the system into sleep mode.  However, during the night, it apparently shut off because, the next morning, when I went to turn it on, I was greeted with a black screen stating the system had shut down unexpectedly and did I want to boot into Safe Mode.  Upon booting, both PowerPoint and Word prompted me to 'recovery' my files that had been opened when the power was lost.

Questions: Why I would not receive a warning from the PC that the battery was getting low, so that I could either check the power connection or have time to gracefully shut down.  That is much more preferable than the system behaving the same way it would if I had simply removed the battery when it was on.

Dell Inspiron 3521 :: Windows 7 Pro - Limited Access / Intermittent WiFi Connectivity

Jan 11, 2013

I have got a new Dell Inspiron 3521 i5 with 4GB RAM - 64 bit OS - Windows 7 - Service Pack 1 Laptop, everything works good except, the problem with my Wi-Fi Connectivity.

The issue I'm experiencing is with the Internet connectivity, my Wi-Fi connectivity loses frequently and I get message saying "Limited Access", and gives me an option to reconnect it manually which is a bit disappointing. .

Rest all works pretty fine, I'm satisfied about it. Just this error, disappoints me.

The troubleshooting I have tried so far is -

1) Resetting router for 30 seconds and restarting it - did not fix my problem.

2) Checking firewall settings - did not fix my problem either.

3) Tried virus check as well, but no fix so far.

Dell XPS 12 :: Constantly Dropping WiFi Connection

Feb 16, 2014

I am getting intermittently dropped wifi connection.  It is a new/nearly new xps 12 convertible from the Dell outlet store a couple of months ago.  I have installed all windows updates including win 8.1.  My network adapter is an Intel Dual band wireless AC-7260 #2.  I searched on the intel site using the auto driver function and it cannot find any new drivers there for it.

I have also set the wifi adapter to "maximum performance" whether on battery or plugged in and it happens anyway (even when plugged into AC).Is there anything I can do for this or does a technician need to replace the wifi card (or do I need to RMA the notebook)?

Dell Latitude E7440 :: Intel Proset WiFi Connection Utility

Nov 13, 2014

I've been having issues with this with this utility either not connecting upon resuming my laptop or even from a fresh start. I visit many offices at I am the IT manger and all the connections are saved in profiles but despite them being saved they won't connect even when I try to connect manually. The only way to get the adapter to connect is to right click Proset running in the tray and click "reset proset". Even now while typing this I am connected via wifi but the proset icon shows "connecting"

I've tried updating the wifi adapter drivers from Dell and Intel directly and also completely removed the drivers and re-installed them but I am still having the same issue.

Dell Latitude E6430 :: Loses WiFi Connection When Dock In EPort

Dec 16, 2013

When I take it off the internet works fine.  

Running two Toshiba 32L2300U 32" tv's that have VGA connections.  Since the eport only has one VGA connection the other is connected with a DisplayPort to VGA adapter.

I need to work from home on two monitors, not the laptop in a dock with the lid open and one TV screen. (Internet is restored when I open the lid as it's in the dock but only one monitor works.

Apple :: MAC - Wifi Connection - Virus Scanner - Optimizations

Apr 25, 2010

Just got my new Macbook Pro 13 a few days ago, so far I love it but not used to the MAC OS so I have a few questions.

1. Is there a way to see the actual signal strength/transmission information for the Wifi connection other then the 4 little eclipses? Doesn't seem like I'm getting a full wireless-n signal but somewhere around wireless-g.

2. When I install a program or at least it has happened with AppCleaner and Firefox, it put an icon on the desktop, sort of like when I have a DVD in with the Eject, Get Info ... etc options, I managed to remove them by choosing the Eject option. Is this normal?

3. Do I really need a virus scanner, I've seen a 50/50 split on yes and no.

4. Any sort of optimizations I should do?

Acer Aspire E15 :: WiFi Connection Disables Router

Sep 21, 2014

I've seen quite a few issues with Windows 8.1 and WIFI on this forum, but this one is a bit different. 
 
I've got a brand new Aspire E 15 that came with windows 8.1.  When connected to the network by cable everything works fine. When I try to connect via wifi strange things start happening.
 
I can see my network.  I try to connect and it asks me for the security key.  Then it connects.  About 1 minute later it says it can't find the network.  Other devices that were happily working on that networks wifi suddenly loose connectivity as well (hard wired devices don't seem to be affected).  I end up having to reboot the router so wifi works for the other devices.
 
I made sure the Atheros AR956 adapter has the latest driver - v10.0.0.285 and all windows and acer updates are installed.

I recently clicked on the wifi icon in systray and right-clicked on my connection and selected "disconnect".  It did, but it immediately reconnected.  Where is the setting where I can control this?

HP Envy TS M6 SleekBook Networking :: Unable To Maintain WiFi Connection

Jul 7, 2013

I just got a brand new HP Envy. However, i have not been able to maintain a wifi connection. Usually it will not connect to my wifi or will only connect for a few minutes and then say 'limited' and then not connect at all. I did the full windows updates for the computer. I updated the drivers for the wifi adapter. I updated the firmware to my router. I also uninstalled norton. None of these have worked, still will not connect or will connect and drop within a few minutes. My system information is as follows:

Product Name: HP ENVY TS m6 Sleekbook
Product Number: EOK41UA#ABA
BIOS (configuration): F/.05-05/28/2013 (0883100022305B00000320100)
Keyboard REvision: 86.32
Total Memory: 8.00 GB
Processor name: Intel (R) Core (TM) i5-4200U CPY @ 1.60GHz

My wifi router information is:
Netgear N150 model WPN824N
Channel is set to auto
Mode: up to 150 MB per Second
Security: WPA2/PSK [AES]

I have two ipads, two iphones, an xbox, a windows phone, two toshiba laptops, and one hp pavillion DM3  that are able to connect and maintain wifi connection with no problem (not all connected at the some time necessarily-it is not an overloading problem). The network is running fine, i just cannot figure out what the problem is with this HP Envy.

Lenovo Yoga 13 Flex :: Wireless Connection Enabled In Win 8 But WiFi Is OFF Always

Nov 26, 2012

I have read about many issues regarding Wifi connection (connection drops often without any reason, poor signal strength, too long time to establich connection...). My problem could sound similar, but it's rather different:

Although my wireless connection appears like Enabled in Win8, I cannot switch it on / connect. It appears like Not Connected (Wifi = Off). In fact,  I cannot see any wifi network when the list of available networks used to be.

- I checked BIOS, and it's set as Enabled.
- I updated BIOS to the last version.
- I updated wireless wireless drivers to the last version
- I modified the wireless configuration as it's especified in the long forum thread for Wifi issues

But nothing has been successfull. For some strange reason, I cannot switch the wifi device on.

HP Envy 17-j053ea Networking :: Losing WiFi Connection With Windows 8.1

Apr 21, 2014

I have an HP Envy 17-j053ea Notebook running Windows 8.1 64bit.  It has an Intel Centrino Wireless-N 2230 network adapter. I am guessing from other posts that this adapter can't handle Windows 8.1 which is why I am continuously losing my wifi connection (other devices not running Windows 8.1 are fine). Is there an update or another driver? installing it and making it work on my notebook?

Acer Aspire One D225e :: Lost WiFi Connection - Can't Get Back On

Dec 25, 2014

I've been using my netbook at my local library for 3 years. Acouple weeks ago, all of a sudden it lost contact with the library's wifi connection. The librarian tried everything he knew, no results. I later borrowed a laptop from the library, looked up fixes, tried them, but they didn't work.

Here's what happened: Got a padlock with a window saying failed to connect to a Windows service. The dependency service/group failed to start. A troubleshoot resulted in a yellow triangle with an exclamation point in it, saying network proxy settings can't be detected, though it also says detected.

Trying the fix on Acer support--checking to see if TCP/IP is working right--resulted in an error message, TCP/IP improperly installed.
Trying rewriting the registry keys didn't work.
Ditto the remove/reinstall network driver adapter.
Finally it said if this doesn't work, there's likely a hardware problem.
