Dell Latitude E5540 :: Intel Dual Band Wireless-Ac 7260 Not Working?
Dec 6, 2014
I have had the following computer for a few days after purchasing from the Dell online store, Latitude E5540. The WiFi was having trouble connecting anywhere except close to my router, but recently the laptop is saying that a driver or hardware problem is detected in the Intel Dual Band Wireless-Ac 7260, and that Windows has stopped the device due to a problem (Code 43). The drivers are up to date, and connecting using an ethernet cable and checking for new updates tell me the drivers are up to date.
I came across an intel 7260 card and installed it in my HP G72 with no problems. The notebook boots into Windows 7 64 bit with no errors. As soon as everything loads I try to connect to the internet and get "No Wireless networks found". I was using the intel wireless manual troubleshooter which stated the "radio is off" I checked the f12 key and have a blue light. Device Manager sees the adapter with no errors. The windows mobility center has the wifi network area greyed out. The Hp Wireless Assistant only shows bluetooth. I switched out that card for the old card and can access my network. if there is an fn key combo I need to press or a command I can enter in the command prompts or a regestry setting that needs to be changed.
I have bought a y510p 755m SLI with intel 4700MQ and it's performance is great, but after 20min it just drops the speed from 3.3mbps to like 2kbps, I tried ALL drivers and none solved the problem (even the windows one). I have to turn airplane mode on and off in order to reconnect. If i disable wireless N it does not disconnect but I lose too much speed (around 1.2mbps) and I really don't want that.
I am currently using a HP DV6-7014nr with Windows 8.1 installed and all of the stock parts out of the box. I have noticed that the stock internal wireless card does is not dual-band. This is a very huge issue with my current situation, in which I cannot take advantage of the possible bandwidth at my regular location nearly as well as if I had a dual-band card installed. The warranty is already up, so I'm not concerned with voiding the warranty, I just want to know if the card I'm looking at will operate correctly inside the laptop. I was going to purchase a Intel Centrino Advanced-N 6235 HMWWB wireless card for my laptop, and I need to know if this card will operate correctly with inside my laptop.
I am going to chronicle my experience with this issue. I have an Acer V7-482PG-9884 with an Intel 7260 AC wireless card running Windows 8.1 which was upgraded from Windows 8. Every 20-30 minutes, and sometimes more frequently, the internet connection drops while still connected to Wifi. Upon running the auto fix within internet explorer, Microsoft identifies the issue as a "The Defaul Gateway is Not Available." The internet connection is reset, and everything works fine for another 15-30 minutes whereby the issue repeats.
I've tried everything, switching to a different Intel Card 6205, using each and every driver available from Intel, nothing seems to properly remedy the issue. This includes playing with the power settings, turning off and on bluetooth, etc.
This is a known and widespread issue with Acer, Intel, and Microsoft.

I have a Dell E5540 laptop and the touchpad is working fine, except that it won't zoom or rotate. All other gestures work as they should - scrolling, three finger-gestures, ...: no problem. But no zooming or rotating.
Both options are of course enabled in the Dell Touchpad settings. I have removed the touchpad from the device manager and reinstalled it with the most recent drivers, but to no avail.
I think it's a software problem since scrolling with two fingers works without a problem?
I just picked up a Latitude E6500 from the outlet, and it only comes with B wireless. People on the forum have mentioned that the E6500 has 3 Mini PCIe slots. One is full length and has 3 antenna connections, one is half length with 2, and one is half length with 1 (for Bluetooth).
I'm planning on upgrading with an Intel 5300 wifi card, it's amazing how cheap they are on eBay. The 5300 comes in two configurations, full and half, but it's a 3x3 antenna, so it'll have to go in my full length slot.
However, most of the listings seem to be for half, and they cost the same. I figure I might as well get the cheaper half length card that also saves .5 ounces of weight if it'll fit in the slot, and the antenna wires will reach. Does anyone know if this would work, or do I need to find one of the full length cards?
I have a HP Pavilion dv6t-6000 CTO Quad Edition laptop and currently the WLAN network card does not support dual band connection via WiFi. I wish to upgrade the WLAN card so that it can connect to the Dual band WiFi at my house.
Any whitelist of WLAN card that I can use to upgrade my laptop? Is there a list of supported WLAN adapters?
I have been running in to an issue lately with a Latitude E5540 laptop.
The specs are:
Intel i5 cpu @ 1.9 ghz 4 gb RAM x32 Windows 7
In my device manager it says that I have an unknown device and there is the warning symbol next to it. When I go to update the drivers it says that it can't find any drivers (I am connected to the Internet). I looked at the hardware ID and noticed that it was APCISMO8810, I then proceeded to research the driver, which I found was the ST Microelectronics Free Fall Sensor Driver. I also know what it's primary function is.
The issue I keep running in to is that I have uninstalled the driver, and tried to re-install the driver from the Dell downloads. However halfway through the process the install wizard tells me that the most recently updated driver from dells site is older than the driver I currently have installed. (even though it says there is no driver installed)
I regularly find that, with a single keystroke, my brand new Dell Latitude e5540 laptop randommly produces 2 spaces (most often) and double letters (sommewhat less often than the doubled spaces, but consistently and predictably). The faster I type, the more oftenn the errors occur... I have found it to be an issue of how hard I strike the keys. The keys controlled by my dominant right hand are most often affected whereas those controlled by my pinkie fingers NEVER have been affected.
I amm only one of many employees at my place of work who all are experiencing the same problemm. I have asked repeatedly for Dell to let me know the extent of this problem and whether they have a recall of this model (which, as far as I can tell, is pervasive with this particular mmodel). My persistent questions have never been answered by Dell, despite numerous contacts with 3 different agents.
P.S. If you notice double letters where there should be single letters or extra spaces in this e-mail and this post scrippt, please read on for the reasonn: I am using the brand new Dell Latitude e5540 computer our school system recently purchased to write this e-mail. I have simmply givven up editing my typing... you're getting the spontaneous errors caused by this computer so you can see for yourself and hopefully to motivate Dell to fix the problemm soonner, rather than latter.
IMPORTANTLY, if you are having similar problems with YOUR BRAND NEW Dell Latitude e5540 laptop you specifically will NOT have tthese problems if you use an external keyboard... it only occurs with the laptop's built in keyboard) PLEASE send me your servvice tag (S/N) nummber from the bottom of your Delll LLatitude e5540 computer and I will include your commputer in my conntact with Delll about this problem. (It is a problemm of this particular model... I have never experiennced this before with any other computer).
Dell Latitude E5540 keyboard and touchpad freeze. Sometimes when pressing Enter the keyboard and touchpad freeze but the laptop keep processing, so I need to restart my notebook to have the keyboard back....
8GB DDR3 500GB HDD Windows 7 Pro x64, even with the preinstalled Ubonto have the same issue.
I opted for 2 7200 RPM drives for my configuration. I also selected the quad core processor, 1gb video and 8gb of ram. I was very close to purchasing with SSD drives, but my first experience with SSD wasn't very good. I purchased one of the first XPS 1330 with the 32gb SSD option. I really bought into all the hype and after about 60 days I swapped it out with a 7200 rpm drive. Anyway, looks like SSD drives have improved drastically.
I was just reading some reviews and performance tests on the Intel X-25 80gb SSD drives. I'm considering buying two for the M6400 and setting them up RAID 0. I really don't care about storage space.
i have been having an issue that has me perplexed, i recently did a clean install to windows 64 bit, and now i cannot seem to get the intel wirless client to work, it will only let me use the windows wireless client. I downloaded the latest drivers and utilities and software, both from the intel website and the dell site, installed both, but does not allow me to use the intel wireless client. what I am not doing correctly to activate the intel wireless client.
if the Intel Ultimate-N 5300 Wireless Wifi Link Card will work on my Dell XPS M1530 laptop?
I currently use the Intel 4965A AGN so i have the 3 antennas connected to it, But i can't find any confirmation that the 5300 will work with the M1530. I see that it says it's for the Centrino 2 but i don't know if it's for a certain motherboard or chipset.
