No internet access appears often on Realtech wifi pci card.

[IamLEGEND]

Hi all.
I m using wifi pci card on acer pc first time. its model is Realtek RTL8190 802.11n Wireless LAN (Mini-)PCI NIC.
after installing its dirver (which is located here REALTEK - Download driver for RTL8190 and Windows 7 64bit)
internet successfully connected. but I noticed most of the time in wifi signal bars a yellow cation mark appears. its says no internet access. although my broadband router (provided by isp) is continuously connected with internet (I checked this by connect internet on cell while No internet access appears on pc).
and then I right click on signal bars and troubleshoot problem. after some loading internet connected and problem fixed. why is that happening,? please help me.

That driver version is a bit outdated, try using the newer driver from the link below dated June 18 2012. If this driver doesn't work then consider updated the routers firmware to the latest version.

Download Realtek RTL8190 WLAN Adapter Driver 2000.4.201.2010 for Windows 7 64 bit, Windows 8 64 bit

Or maybe try different driver versions directly from Realtek

If you trying different driver versions and none of them seem to be working then it's very likely that the problem is with the ISP issued modem/router's which can be very problematic. Might be better off using a standard modem plugged into a router but sometimes it's fixable.

With default gateway problems it sometimes helps to type the gateway IP into the IPv4 properties, then just type the gateway IP into where it says 'default gateway. The one I'm using is just an example of a typical router gateway IP. If I can see ipconfig/all then you can find the gateway IP.

Try reconnecting on your phone right when the problem happens on the pc. My router for some odd reason, there will be times that new connections cannot be made and i have to restart it.

Well that's good, finally I fix something for you.

Adding the gateway IP statically is an old trick that works to fix compatibility issues between the adaptor and router or modem. I'm glad this trick worked for someone because it doesn't always work.

thanks.

wtf is that. internet runs normally without problem just for 2 or 3 days. now its happening again. adding default gateway either didn't solve the problem, instead adding the gateway disconnect the internet. and sometime. when I add gateway, it did not actually add. and the gateway box is empty. if its add then internet gone. any other solution will highly appreciated. waiting.

In this case the ISP issued router/modem is the most likely problem.

I believe you should try to start up in safe mode with Networking to see if the problem persists when in safe mode.

It may also help to try connecting to a different router and see if the problem persists.

You could also try using a static IP which may help with the handshake problem you seem to be having.
- Click Start Button
- Type: ncpa.cpl
- Right click the Wireless Adapter and choose PROPERTIES
- Click and highlight the Internet Protocol TCP/IP Version 4 option
- Click the Properties button
- Choose “Use the following IP address”
- Enter the following for the IP address: 192.168.1.xxx- the xxx should be an address that is outside the range of DHCP on your router.

Enter the following for the Subnet Mask: 255.255.255.0
- Enter the following for the Default Gateway: 192.168.1.1
- Choose “Use the following DNS servers”
- Enter the following for the Primary DNS server: 192.168.1.1
- Enter the following for the Secondary DNS server: 8.8.8.8
- Click OK
- Click OK
- Reconnect to the wireless signal
