I have an Acer Aspire 4720z that keeps dropping the internet signal. I know it's not my router, because my wife's HP keeps on plugging.
While the connection is working, I show two wireless cards in my device manager:
1. Atheros AR5007EG
2. Broadcom NetLink Gigabit adapter
About once every 30 minutes to one hour, my connection will just die cold turkey, and checking the device manager shows that the Atheros card has just "disappeared".
I tried installing drivers for it again, but it just tells me that no such device exists.
The only thing that works is to reboot completely. Then it works for about another 10-30 minutes and the process starts again.
a problem im having with my Acer 6920G, basically the network card is an Atheros AR2181, and ive been having problems with it since day 1.
Basically the drivers it came with (1.0.0.28) would cause my internet connection to "suffer" limited connectivity every 5 minutes or so which would srop download speeds to around 1 kb/s. I thought i should upgrade drivers to the latest which are the 1.0.0.38/9 drivers, i thought i had fixed the problem as for the first 10 minutes or so it was working fine, and then suddenly my pc froze and the screen went funny with lines running across the whole thing, as if it was an overheating issue.
To solve this i bought a USB network card, which works fine but takes up a USB slot and gives me slow download speed of around 20 - 100 kb/s compared to over 10 Mb/s in some cases with the Atheros.
Recently bought a Acer Aspire Nitro v15 with windows 8.1 with a qualcomm atheros ar5bwb222 wireless network card. The connection is really unstable and often disconnects and have very few bars. This is not from the router since the connection on my phone and other computers are fine. The connection (when i have it) is also really slow compared to when i use my phone on the same network. I tried updating the drivers but it says my latest drivers are installed. Could this be a Windows 8.1 problem? this is my first time owning a windows 8.1 computer.
I have an Acer 5100 complete with the godforsaken Matshita UJ-850s DVD recorder drive, and a few months ago, it started not showing up in Windows at random times. It stopped showing up altogether a month or so ago. I've done the registry edit suggested for this drive, as well as opened up the computer to check the connection to the motherboard. The drive light comes on when a disc is inserted or when the eject button is pushed, but nothing registers in Windows. In addition, the drive doesn't show up in BIOS setup.
Well, as many of you may have seen on the news (in the US anyway), Louisville, Kentucky was hit by some massive storms on August 4th.
I was unlucky enough to be on the campus at the University of Louisville, where I live in a dorm. During the rain and thunder, I was surfing the web and watching a little TV to pass the time due to canceled classes.
All of a sudden there was a bright flash, and a loud crack and boom. I had later been informed that the building was hit by that particular bolt of lightning.
At the same time as the flash, my laptop completely froze, forcing me to hard reboot. Nothing else in the room was affected. Lights didn't flicker once, TV never skipped a beat. My electronics are all plugged into a quality surge protector; this and the fact that we still had power and cable, I knew there wasn't a power surge.
However, the internet was knocked out for the whole building. Come to find out today, my laptop no longer recognizes when an ethernet cable is plugged into the port, thus preventing me from connecting to any LAN; home, on campus or otherwise.
QUESTION
This leads me to the question: Is it possible for there to be an electrical surge carried over an ethernet cable that is strong enough to fry/disable an internal network card?
In case you're wondering, I'm currently connected via wireless. Specs are in my sig (Dell E4300).
I've been using my laptop daily with its ethernet port for my internet connection. A few times a week I'll use the wireless connection, which is easy enough to switch on and off.
Today when I got back to my desk and plugged in my ethernet cable, nothing happened. No orange/green flashing lights, nothing.
Wireless still works fine, but I can't get a byte of internet out of the wired LAN connection. The device manager says it's a Marvell Yukon 88e8040 PCI-E Fast Ethernet Controller.
Pinging loopback (127.0.0.1) works just fine and the device manager says that it's working properly
I was wondering if any of you knew if it was possible to change the stock dell 1515 wireless card with a real card like intel's 5300 ? (the same one you can find in the 1640)
I'm asking because i want to install linux on my lappy and besides having crappy performance, those dell cards are not really compatible with linux.
My dv2000t came with Vista installed but Vista is now broken and gone and I want to install WinXP instead. I installed XP but XP cant find any network adapter on the laptop. I have an ethernet cable plugged in to the laptop. Prior to this there was no problem connecting to the internet with this machine. Win XP can't find the network adapter therefore I can't use the internet at all. Since this dv2000t came with Vista installed maybe the network adapter requires something not available in XP therefore you can only use it with Vista loaded.
why XP can't find any network adapter on this dv2000t?
I buy from lenovo mini pci wan card gobi 2000 and I receive the Error 1802 : unauthorized network card is plugged in - Power off and remove the miniPCI network card.
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?
About 3 days ago my pages app disappeared from my iwork 08 folder. The next day my safari and msn messenger were gone then today my sons World of Warcraft is missing and a few documents have vanished also.
I just recently received a warranty exchange to an XPS M1330. It's been working great up until the past few days. When I swap discs out of the drive 4 times in a row, the drive disappears from the "Computer" folder. The drive is a Matshita DVD +- RW. Dell tech support ran me through all sorts of tests, none of which solved the problem . They are going to send out a techie to replace the drive.
Does anyone know are have had this problem? If so, what was the solution?
Does anyone know how to prevent the NVidia drivers from disappearing?
I just installed 32bit vista and installed the drivers. Shortly afterwards, they disappeared and only the standard vga adapter was listed. I tried uninstalling and then reinstalling the drivers again.
Again, the 160M was listed correctly. I then installed PowerDVD which wouldn't play. I went back to the adapter and it had reverted back to Standard VGA
Recently the WLAN on my Vaio Z27GN started acting up. The slightest touch on the laptop internally disconnects (or shorts) the WLAN hardware that totally disappears from the device manager. Usually a few gently tapings on the back and a reboot fix it.
The problem has gotten worse to the point that now its gone forever. It is clearly a short, a loose wire or something connecting/disconnecting the hardware. This has nothing to do with the front sliding switch to turn on/off the wireless.....
I have a Compaq Presario F572US, and for some odd reason, my wireless adapter keeps disappearing! I reinstall the wireless adapter software, then I make sure the wireless switch is turned on and after a number of reboots, the wireless adapter will show up, for me to connect to a wireless network. Once I reboot, then the adapter just completely disappears! I go to device manager and I don't even see it in the network adapter section.
I scanned for virus and spyware and my system appears to be clean.
Windows 8. I recently got an Inspiron 15z touchcreen ultrabook with windows 8.
Often I'll be on the net/playing a game/composing an email/pretty much anything and my mouse will disappear and I can't make it come back. I can still use the touchscreen; but no matter of swiping or clicking the touchpad makes the mouse come back.
My touchpad driver keeps disappearing and its the only way I can disable the touchpad - I much prefer to use the mouse and I am a touch typist so the touchpad is a nuisance. Unfortunately I don't seem to be able to find a win 8 touchpad driver or other way of disabling the touchpad - win 8 even on a standard laptop is magic and has improved my older laptop no end but its now annoying me due the limitation of drivers and the fact that the only way one can disable the pad is via the driver settings?
after some microsoft updates my Elitebook 8570W doesnt show me my brightness and volume bar anymore. sometimes when i restart my notebook he does show but after i plug in my BOSE portable via the headphone output he doesnt show it anymore (which he did before the updates).
i know you probably got this question alot and i searched a bit of the forum but couldnt quite get the right awnser. (and im not that familiar with HP but im quite confortable with).
My cursor is constantly disappearing, and I cannot get it back without restarting the computer. Everything else works fine. Is there a button I am pressing by mistake?
I've had my Dell L701X for over two years now and I've had some trouble with the wireless adapter before, particularly within the last 6 months.
Recently, the wireless adapter has been disappearing from the device manager and I have had to resort to a wired connection. The adapter has been disappearing completely from the device manager and I am not sure why. I have tried reinstalling the Intel drivers for the wireless card but that hasn't solved the problem.
The components list for my laptop on the Dell website under components says I have the Intel WiFi Link 6200 (802.11a/g/n) Half Mini-card. Also if I use the wireless hardware switch it seems to be turning the Bluetooth connection on and off in the network adapters.
Currently running Windows 8 but have also had the problem while running Windows 7.
I recently got this computer. When I got it, i tried the webcam and it worked ok. The second time I tried to use it, with the "Camera" Windows app, I get a message that says "To get started, connect a camera".
I googled for solutions and discovered that the "Imaging devices" category had disappeared from the Device Manager.
I downloaded several drivers, and the only one that worked was this one. After installing it, the camera worked ok, and the "Imaging devices" reappeared in the device manager. However, after rebooting the computer, the camera stopped working again and the "imaging devices" category disappeared as well.
This is a temporal solution because everytime I want to use the camera I have to install the drivers first, knowing that sooner or later the camera will stop working and the device will not be recognized by Windows anymore.
I've been having an annoying problem with my notebook's audio. Quite often, when I turn on my pc, my audio disappears after a couple of minutes. Sometimes there's no sound right from the start. The mute button stops working, because normally there's an orange light when you turn off the pc sound, well that doesn't happen anymore. Windows Media Player can only play such formats as mp4, avi etc with no sound in the background.
However, it can't open mp3 files at all (error message shows up). Videos on websites such as youtube stop playing after a few seconds (although the buffer is still running, and of course there is no sound). So basically, there's no type of audio coming from the speaker (like error sound, message sound, command sounds etc...) I tried connecting headphones and external speakers, but no luck. I updated my audio driver, but it didn't work.
Furthermore, when I launch audio test from Control Panel, an error message shows up which says "Device currently used by another application. Please close all the applications that are using the device, and retry."
My notebook is quite new. It's an "HP Pavilion 15 - e070sl"....
I have an HP Pavilion Sleekbook Touchsmart 14-B132TX. My sound disappeared while I was working using it about a month ago. I phoned HP Hotline and the Tech Support told me to just uninstall it from Device Manager and upon restart, the driver will install automatically. Which I did.
The sound did come back but again it disappeared after about 15 minutes of use, so I called tech support again and they gave me links to HP Support for drivers to download and install which I did and restarted the computer and the sound came back again. BUT AGAIN, the sound disappeared. I phoned tech support and they told me to just do a system restore which I did and the sound came back again. But it again disappeared after about just 7 minutes of use.
These are the drivers I installed from HP's website: sp60642, sp64082, sp60464 and sp64031. After so many reinstallation of drivers. I cleaned my notebook with CCleaner and went to HP Support Assistant in the hope of getting a solution, there was an instruction there to download the QUALCOMM Atheros driver, and I installed again the said driver..The sound reappeared after restarting. AND AGAIN, it disappeared after just using the laptop for just about 3 minutes. This laptop is quite new, just bought it 10 months ago. I'm using the Windows 8 OS.
I have a Envy Spectre 14" with Win 8.0. For the last month or so I have sound disappearing (totally) at random times. Rebooting has generally solved the problem...but that can be a pain if I'm in the middle of a lot of projects. It was working this morn....closed the lid...opened it 30 min later and NO sound.
