Realtek rtl8187b wireless 802.11g keeps disconnecting and not detecting networks

My wireless adapter keeps disconnecting. It'll not register any networks for days and I have to then use the Ethernet cord to plug into it directly. After a couple days...it allows me to connect wirelessly as normal, while also being able to detect other networks. After about a day or 2 of wireless use, the whole thing starts up again and will not work. I' have tried everything that I found on the net for troubleshooting tips. This has happened out of the blue and not long after my USB ports simply stopped working.

    If the connection drops no matter which wireless network you are connected to, the problem is more likely with your laptop's wireless card or internal wireless device.

    I downloaded the program from your link, but I'm not quite sure what it did. I ended up with a few games that I removed and once download was finished, the folder for that software was empty

    which operating system ?? W 7 First, please disconnect all USB devices and then perform the following steps Click Start button, type devmgmt.msc in the Search bar and press Enter. Click Continue if necessary. In Device Manager, double click to expand Universal Serial Bus controllers, right click on the Host Controller, click Uninstall and click OK. Repeat the step 2 to uninstall all items under Universal Serial Bus controllers. Then restart your computer and Windows 7 will reinstall all USB controllers automatically for XP or earlier click start right click on computer select properties device manager scroll down universal serial bus controllers you could see a yellow question exclamation mark? ! or a red X you will need to update reinstall drivers right click to reinstall drivers if you can see your usb drive but its not working ports (com&lpt) right click update driver Rather doing a driver hunt which can take hours http://download.cnet.com/slimdrivers-fre... Windows XP/Vista/7/8 it might take some time being a freeware driver solution Note it will find all of your outdated drivers This will automatically search for and find the correct driver you will have to update every driver individually once you update you might be asked whether you want to restart or make a system restore point. Click no to both of these then continue updating each driver free then restart once all of the drivers have been updated.

    Ok... I uninstalled and then reinstalled the USB Controllers and restarted. There are not yellow nor red indicators of there being something wrong. In fact, everything in the device mgr claims that it is working properly. This is one of the things that threw me off and had me confused from thr start. I'll now go ahead and try the slim drivers freeware. I'll keep you posted

    Ok. It was doing well for a little while, however, it was behaving that way for about a day, where it would go consistently for about 9 hours or so then drop out. It dropped about 1:30am and then I managed to get it up again after restarting. It's done it again as of about 30 minutes ago. I'm happy with that Slim Driver things, as I am sure that it helped out quite a bit. I came out to the living room and connected through the ethernet cord in order to send you this message and try to maybe find something else. Can you maybe think of any other possible scenario?

  • Brian Sullivan
    Brian Sullivan Jan 06, 2013

    There might be something wrong with the wireless network card (if applicable) or the wireless modem if its just dropping out the driver might have become unstable and need to be updated although slim drivers would have found the latest driver for update or a virus or malware make sure your antivirus is up to date what sort of wireless modem or card do you have ? you might have open up your laptop remove then reseat the wireless card if its what you have

SOURCE: Wireless Network stopped detecting ALL local networks

Hi, Have you installed the driver for your wireless card since you re-formatted?

Right click on my computer and go to properties, select device manager. all of your hardware will be listed there. are there any yellow question marks? these are devices that need drivers.

Your wifi card will probably be called 'network adapter'. go to the sony vaio website and download the right driver for your wifi card

You may need to update your Wireless drivers:

Unlike the newer laptops, the T42 doesn't have it's own wireless switch. So in order to get the wireless working, you need to also make sure that the Power Management driver and the Hotkey driver are installed as well.

Load the drivers in this order:

1) Power Management driver - http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-4GXPEG
2) Hotkey driver - http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-68000
3) Wireless Driver - http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-70504
After downloading it, you must go into C>Drivers>Win>Wlanint and run the setup file from there.
4) Access Connections (Optional) - http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-4ZLNJB

Try checking your computer's driver. Right click on Computer. Go to Device Manager. The device drivers are listed in the device manager. Drivers are used to make your computer parts communicate with the operating system. If it has a problem, then the part won't work.

Check for your wireless driver - update it. If no go, then try turning off your wireless adapter in your computer and turn it on. Check = if no go. Try going to safe mode with networking.

To go to safe mode. Do the following:

1. Restart your computer. While it's starting or booting, keep tapping F8 until you see the options to go to safe mode with networking. Use the arrow keys to highlight safe mode with networking.

2. Let your computer start in safe mode. Check if wireless is working fine.

If you want to avoid this kind of problem in the future or if you want to make sure that your computer is running well, then install Radarsync.

My driver detects wireless networks then for no reason doesnt detect any then i restart my computer then it detects them again. wat could be the problem?


Make sure you get the Realtek Wireless Lan Utility; if you're not using it now you're lucky you can connect at all.

When you get that installed, or if you already have it, find the file in the REALTEK install folder called 8185.ini (or 8185x64.ini on a 64 bit OS), delete everything in it, and paste this into it. It'll give you more control over the card and open up new options in the wireless utility.

Realtek RTL8187B wireless NIC hangs after a few hours


The computer needs a new NIC. If you don't want hangs and lags. Buy a new one. You can still use that NIC but with the less load of course. The NIC maybe old and when electronics ages, the performance downgrade can be seen.
