    I have the same problem, droping the signal less then 50 from the router. Using Microsoft Vista. Any ideas on how to fix this problem is appreciated.

    Having the same problem.

    When the PC and the wireless router is in the same room - it works intermittently, but when PC upstairs, the signal strength is good, but will not connect.

    This is my son's laptop. He was always frustrated because it would drop the signal. I thot it was a setting. Just got the thing back on warranty with new motherboard - restored the harddrive and can't get the realtek 8185 to work properly. It did for 2 downloads and now, nothing. Have tried all the config possibilities on the utility. It' won't even detect the wireless networks.

    What if the Rollback button is not available.. its there, but grayed out..cannot push it.

  • ampaino14 May 11, 2010

    I've had those updates since they came out and they haven't helped at
    all. I'm not far from my router and my internet mysteriously
    disconnects all the time. I can't even play online games anymore. I'm
    not positive but I'm pretty sure I didn't start having this problem
    until I updated to Service pack 1. The only difference is that I don't
    have to reboot, I can just reconnect.

Go to the Device manager and bring up the properties to the realtek 8185 device. There is a tab called Power Management. Click on this tab. There is a checked checkbox that says Allow the computer to turn off this device to save power. Uncheck this box. This should stop the random disconnects.

There are two optional updates through Microsoft for the realtek wireless card. I've had to reboot my computer 3 to 4 times a day, and I finally got sick enough of it that I went onto Microsoft's windows update site. Since my computer only downloads the "mandantory" updates, who kows how long the optional ones have been waiting. Since I downloaded the updates this morning I haven't had any problems. Keeping my fingers crossed! Good luck to you!

My Realtek 8185 wireless adapter on Vista and I also have the same constant problem with the adapter dropping the signal for no reason at random times all day long. This Realtek 8185 is a total POS.

anyway, the "solution" I came up with is to open device manager and disable then re-enable the 8185 network adapter. This works about 75% of the time. The other 25% of h time rebooting is necessary. Seems like the suggestion to get another wireless card is the best one. The Realtek 8185 SUCKS. ...and Realtek apparently doesnt care at all because they have not released a new driver and this has been a problem for a long time.

Posted on Dec 21, 2008

There is tremendous variation in the hardware between devices that contain the Realtek 8185 chipset. If there wasn't a vista driver in the box that came with your card, then the chances are you are using the generic one that comes via Microsoft update.
I am using this one too, and it is rubbish. The device randomly stops functioning and I have to disable and reenable it to get it working again. Basically, it is not 100% Vista compatable. Buy a new card that comes with a Vista Driver. Or solve all your problems and upgrade to Windows XP SP3.

If nothing else works and you are using a secured network i suggest downgrading from wpa2 to normal wpa, this greatly improved my signal stability and range. Remember as long as your using better than WEP it is your passphrase that is the weakest link so if thats strong WPA-WPA2 not much difference for home user

If you update the drivers from microsoft, your wireless adapter will stop functioning properly, use the default drivers or the drivers that came with the laptop. DO NOT USE THE WINDOWS UPDATE DRIVER.

Over all this Realtek 8185 Card is a POS, it's even a problem under Linux. very unstable card with horrble range. Thats why i like atheros chipset wireless cards, broadcom chipset would be my 2nd choice.

Keeps dropping signal to iPhone & computer


Hello!

I am not able to locate a model 67, so I presume that is short name for it.

Can you look at the label on the bottom and get the full model name? Examples of Netgear model names are WRN2000.

As for the signal dropping, it is possible that the router needs a firmware update. I would suggest searching for a firmware download for the modal have.

Good luck!

Win7 & vista keeps losing connection with WBR-2310 router


Signal strength drop or fluctuation are common causes of RF interference.

Try these basic troubleshooting steps:

• Change the channel on your access point or wireless router.
• Change the location of your wireless products. Subtle changes (2-3 feet) can make a big difference. Do not put the access point or wireless router in a cabinet or enclosure.
• 2.4GHz phones, X-10, and bluetooth devices will interfere with your wireless network. Change the location of the base for your phone, or downgrade to 900Mhz phones, or upgrade to 5.8GHz phones.
• The wireless signal will degrade (or die completely) when going through brick (fireplace), metal (file cabinet), steel, lead, mirrors, water (fish tank), large appliances, glass, etc.

If your wireless connection is only dropping during large file transfers or when a large number of wireless clients are connecting, change the preamble on all wireless devices to short.

Connect to network wirelessly with in 20 feet when go down to second floor network indicates no internet , but it can find router , run network trouble shooter but not much , dell has not helped ...


Hello
Signal is either too weak or something is causing it to drop out.You can try a reboot of the router.
If this doesnt work then you may need to get a wireless switch to pick up the signal from the first floor to the second.Which will need to be located in an open area like stairs.Metal decking and flouresent lights can cause the signal to drop.

Or you can buy a cable and hardwire it.Or a stronger router with a better signal.

Wireless-g router can only extend it's wireless signal up to 50 to 75 feet. You can use a wireless signal extender to be able to extend the signal further. And yes, you may have password on the wireless network.

It seems that the signal is strong next to the router, but drops to 1 bar within 30 feet away? What is the most likely solution.


Hi,
Routers generally have a strong signal for up to 10 meters. However no obstacles should be in the way. 30 feets is about 10 meters so the router is loosing its signal strength. If you would like to extend the strength of your router you can buy a range expander. This device acts as a repeater of the signal so from 10 meters you can go to 15 or 20 meters.

Signal strength keeps varying


if you arent in a clear line of sight, many things can affect the signal strength of your network including the thickness of the walls, the composition of them and anything else that may be in the way. if you use a 2.4 ghz router and you have a 2.4ghz cordless house phone, they can interfere and cause issues. A microwave oven that is located between the router and a device can cause interference as well.
