My usb wireless adapter keeps disconnecting

So, I just bought this TP-Link TL-WMN721N 150mbps wireless adapter, and it has this issue. It keeps disconnecting, all the time, i've downloaded the latest drivers and i'm pretty sure it's not a malware problem, also tried connecting to different usb ports.
Any guesses?

Hi，
You can also temporarily turn off your anti-virus software, since some anti-virus might not recognize the new component installed.
I noticed that you've had the latest driver, did you get the driver by manually viewing the device manufacture website to look for the latest version?
This issue can also be caused by incompatibility, Please make sure the usb wireless adapter is compatible with your Windows version.
Please also reinstall the usb controllers as a test
First, please disconnect all USB devices and then perform the following steps:
1)    In Device Manager, double click to expand "Universal Serial Bus controllers", right click on the Host Controller, click "Uninstall" and click "OK".
2)    Repeat the step 2 to uninstall all items under "Universal Serial Bus controllers".
Then, restart your computer and your windws will reinstall all USB controllers automatically.

  • Can I use a USB wireless adapter with my iMac G4 Flat Panel (it has no Airport card).

    I have just salvaged an iMac G4 15-inch Flat Panel from the skip and now have it running Mac OS X Tiger 10,4. It has a 700mhz cpu, 80Gb hard drive and 512mb of Ram. No airport card is fitted so I was wondering if a USB wireless adapter could be used instead. I have a Belkin F5D8055ea USB wireless adapter fitted and the system recognises the device, this is as far as I have got as I am a complete novice on Apple/Mac machines. Anyone any ideas please?

    If the device is recognised, see if you can located your wi-fi network using Airport Utility.

  • Issues with usb wireless adapter

    Hi
    Please excuse my ignorance.
    I have an imac (about 2 years old) with a built in airport card. I am trying to use a usb wireless adapter. It has a realtek rtl8187. we have a wifi network here that works with my pc using this adapter but i cant get it to work on the mac. You have to sling the adapter on the window sill but it picks it up fine.
    I have installed the supplied software (obviously the mac one!) and it installs the software and driver. After i have restarted, and plug the thing in, it tells me to turn on my wlan card on the supplied software?? It shows up in the listing on network settings as ethernet adapter ((null)). I cannot find any setting to turn on my wireless card, i thought that was airport?
    The airport picks up the network but the signal is too weak to connect, hence the adapter with a bit more guts....
    I have this beautiful mac, colecting dust and am having to use a pc!
    If i connect the usb adapter without installing the software, it constantly has a box popping up in network settings saying that an external device has changed settings! it doesnt stop doing it, until you delete the location...
    Can anyone help? I may be being thick and dont have a wlan card or something or airport will not allow me to use this thing. I only just started getting into macs when i moved to spain, where it has sat colecting dust for 3 months.
    I would appreciate any advice.
    Thanks

    TNHusker, welcome to the forum.
    Cisco makes a router that is good for two-story homes.  I have used it for several years.  My router / hotspot is on the second floor and my Blu-ray player and laptop are on the first floor.  Both work extremely well with the router.  They also make a USB, AM10, that works very nicely with a desktop without a wireless card.
    I have had a few problems with both, but have always been helped successfully by Cisco Customer Service.  They are very good.

  • Will airport work with a simple USB wireless adapter?

    I'm considering setting my folks up with one or maybe two airports for wireless audio through their house. They don't have any wireless gear at the moment. Will it be ok to buy a cheap USB wireless adapter for their PC to transmit to the airports?
    I'm considering this one: http://www.ebuyer.com/product/107691
    My worry is that it might not send a strong enough signal. What do you reckon?
    thanks!

    I don't have first-hand knowledge of this particular USB wireless adapter, but it should be compatible with the AirPort base stations, as it is 802.11b/g-compliant and supports both WEP & WPA encryption.

  • Wireless connection keeps disconnecting - Satellite C650 16U

    Hi
    My wireless connection keeps disconnecting frequently and I have to manually reconnect it. I don't think it is a router issue as this doesn't happen with other laptop that is used in my house. Any ideas why this is?
    Thanks

    Hi mate
    I recommend checking the power saving settings in Win 7 power management.
    There you can change (disable) the power saving for WLan card.
    This helped in my case.
    Please also check this thread:

    As I said; power management setting is the key you should also update the WLan driver!

  • Wireless keyboard keeps disconnecting and reconnecting

    My Wireless Keyboard keeps disconnecting and reconnecting and typing by it self!! any ideas?

    Hi,
    Yes believe it or not my problem was caused by the keyboard being too close to the iMac display, the bluetooth was infering with the other radio signals coming from the antenna, it needs to be at least 1ft away from the display (30cm) to prevent this (this won't help those of you with small computer tables/desks)
    Hope this works for you....

  • Wireless mouse keeps disconnecting

    My Apple wireless mouse keeps disconnecting about every third time when I put the computer to sleep and wake it up later.  I have to reboot to re-establish the bluetooth connection.  What can I do to fix this?

    There has been a lot of discussion about this.  This thread has many suggestions.  https://discussions.apple.com/message/13074761?messageID=13074761#13074761
    I have had this problem on an off (no pun intended) for a very long time.  Had my mouse replaced once at the Apple Store.  Contacted Apple Care about it also when it first occured.   Sometimes changing the batteries helps.  If I am using rechargeables, Energizers seem to fit best.  In one of the threads, someone showed a photo of how the battery contacts are actually different on different brands and suggested that is one reason this occurs.  I find that resetting the SMC is what eventually I have to do and that is what Apple Care suggested also.  I haven't found a permanent fix yet and I don't really expect to, but doing this does give me much longer periods of time without a recurrence.

    It is annoying.  I keep my old wired mouse close by so I can get to it quickly.

  • HT1338 my wireless keyboard keeps disconnecting for no reason, I press the side button and it connects again.  Frustrating.

    My wireless keyboard keeps disconnecting for no reason.  Frustrating especially when you are going full on and nothing there.  I press the button on the side and it connects again.  Happening more frequently.  Purchased in March. 
    Any ideas would be most appreciated.

    I just have to ask, Is the battery due to be replaced by any chance?
    Hope this helps

  • USB wireless adapter - interface name keeps changing

    I have used different usb wireless (G) adapters with my 12" Powerbook G4.
    Each was automatically assigned an interface name (BSD) such as en2, en4.
    I recently updated to a Wireless N dongle (D-Link DWA140) which works great with my new Belkin Wireless N router.
    I have had a few connection problems where the dongle was named as enNull.
    After rebooting and re-entering the ip address via DHCP, I noticed that the same dongle has been renamed each time e.g First as en5 then en6, 7 and 8. It's now called en10
    It works fine but is it possible to reset the name/number of this wireless adaptor using something like ifconfig in the shell Or some other way. I understand that en0 is built-in ethernet and en1 is Airport. I have 2 other dongles which are still identified as en 2 and en4. But my current dongle has an inflation problem and I would like to reset it if possible to a lower number.
    Is this possible or am I mad to even consider it?
    any help welcome.

    That is very strange that PCI cards would keep changing names between reboots. Maybe you should investigate that to figure out what's going on. Check the dmesg and journalctl after each reboot and see what the interface is named as. Maybe that will give you some clues as to what "external" program is responsible in naming the interfaces.

  • IPOD and USB Wireless Adapter Fighting!

    I've got a Motorola USB Wireless Ethernet Adapter hooked up to my Dell desktop running XP. When I put my iPod in it's cradle, it disconnects the wireless. I've tried moving the iPod onto the other USB bus, but I keep getting the same problem.
    Any suggestions?

    Hi Emily & welcome to the discussions:
    My first move would be to switch from usb to firewire connection. Much more stable. If your Dell does not have firewire, I would opt for the Adaptec Firewire 4300 card that is so highly recommended in various threads here.
    I have wireless usb devices working along side my firewire connection for the pod and have no problems.
    Good luck,

  • Having trouble setting up Ralink USB wireless adapter

    Hi all,
    I recently bought a usb adapter for my G3 which is running Tiger. Downloaded the most recent driver from the Ralink website and it appeared to install fine, however when I double click on the 'Wireless Utility' app to configure the adapter it won't launch.
    It doesn't bob in the system tray, it just does nothing. The adapter itself is recognised and shows up in the profiler but I can't use it as I can't put in the WEP password or anything.
    So far what I have done is repaired the disk permissions and tried reinstalling the driver several times.
    Does anyone have any suggestions?
    Are there any alternative programs I could use to configure the adapter with? When I open the network panel it shows up as 'en2', but then if I click 'assist me' the airport option is greyed out.

    Not sure what else you can try. The answer may lie out there on the internet somewhere if you could just happen upon it during a search. Hope something turns up for you.
    PS I vaguely remember that when I installed the software for my Macpower Newer Tech USB wireless device there were instructions that were very specific about the installation. They said it was very important to either install all the software first and then connect the USB device or vice versa. I can't remember which way it was. Maybe you could give it one more shot and uninstall everything, disconnect your USB device and start over from scratch. I'd try installing all the drivers before connecting the device.

  • Why does my wireless keyboard keeps disconnecting?

    I have a wireless track pad and keyboard (no number pad) that I use at school. I have to use a usb bluetooth adapter because the Mac Pro the school has does not have native bluetooth. My trackpad works flawlessly but my keyboard has problems. Most of the time it can not connect at all and the few times that it has connected it disconnects very soon, even while i am in the middle of typing something. This is very annoying. I have changed the batteries with a fresh pair and still the problem persists. Please help me, this is very aggrivating.

    HellO:
    My normal suggestion would be to make the KB a favorite, but I am not sure that would work at your school.

  • Usb wireless adapter for solaris 10 on sparc platform

    Hi,
    First and foremost, I hope that this stands in the right place.
    I need to configure my Sun Fire V240 to connect to my wireless network (wifi).
    Just wondering do we have the list of usb wifi adapter (and driver) that can work in Solaris 10 on Sparc platform?
    Or, can I have the list of Solaris supported PCI wifi adapter and driver? It would be great if instruction included.
    Thanks in advance.

    Hi guys, I also had this situation and since I was not able to convert the package to a datastream, I downloaded it from http: //www. sunfreeware. com/mozilla .html
    They also provide some readme files that can be of help.
    Once you have the datastream package you can install using pkgadd utility.

  • Wireless router keeps disconnecting...

    Hello there,
    I own a Linksys Wireless Router (BERW11S4). I recently updated it's firmware to the latest version (1.52.02) which supports WPA-PSK (TKIP).
    I have set the group renewal interval of 7200 seconds, which is the max the software will accept.
    My problem is after a certain period, it keeps disconnecting, which i believe is because of the group renewal interval, which can't be turned off. How do I eliminate this problem as it is really annoying to keep re-connecting half-way everytime?
    Thanks in advance.

    still disconnecting every hour and then...
    please help. im so frustrated.
    any other settings i should try?
    or solution?

  • Bluetooth wireless keyboard keeps disconnecting

    Hello,
    My wireless keyboard {small aluminum, no numeric pad}  keeps disconnecting after i changed the batteries yesterday - the keyboard is found and paired to my iMac, however whenever i press the Command key, it disconnects if i press the space bar it outputs a space followed by the letter 'n' {like so " n"} also i cannot use the delete key, very strange!
    I have tried resetting the PRAM, disconnecting the keyboard and starting over, but still getting the same problems, any ideas on how i can fix this?
    KR,
    Aaron

    Hello:
    Try a couple of things:
    1.  Reset the SMC (you already have reset the PRAM).
    2.  Trash a preference file (com.apple.bluetooth.plist) and then restart.
    3.  Make the KB a favorite.
    If none of that helps, try removing and then replacing the batteries.
    If none of that works, I would suspect a failing KB.
