    WIFI connection problem/Slow speed

    ChilinIntel

      Sometimes it connects to router  but  internet is like 20 kbps, speed test: http://www.speedtest.net/result/2746428758.png . More times it says that: windows was unable to connect Edimax(router).

      Troubleshooting says that problem is with WI-FI adapter or access point.

      I tried:

      Power saving options

      Windows repair and reinstalling

      Transmit power to High

      Newest WI-FI updates(Bios update included)

      __________

      Laptop Dell Xps 15 L502x

      adapter: Intel(R) Centrino(R) Wireless-N 1000

      __________

      WLAN works - Perfectly

      Windows Network diagnostics says - Your computer appears to be correctly configured, but the device or resource (DNS server) is not responding

       

      Recently I disassembled my laptop to clean from dust. Also changed termo pasta for cores. Can this effect wifi? p.s. while assembling pc all wires were connected  correctly.  Do I need re-assemble it again to check it out?

      So what solutions u can give me? Any Idea?

      Best Regards,

      Auris

          Hello Auris,

           

          It seems to be the issue is specifically related to your internet connection or configuration. It does not seem to be related to the wireless adapter or its local connection.

           

          Most of the times the DNS is set to automatic, unless your Internet Service Provider gives you a specific configuration; therefore you may check with them regarding your internet connection.

           

          You may verify your wireless adapter DNS settings from Control Panel, Network and Sharing Center (Network and Internet), double click the Wireless Network Connection in use and then click on properties, then double click Internet Protocol Version 4. It is also a good idea to check the router's configuration and update its firmware.

           

          You may also see your local network (not the internet connection) has a higher transfer rate by running the following command in CMD:

           

          netsh wlan show interfaces

           

           

          Even though the integration of other components does not necessarily affect the wireless adapter we strongly recommend checking about this with the computer manufacturer since Intel Wireless Adapters are meant to be professionally installed by Original Equipment Manufacturer (OEM) technicians.

           

          I hope this information helps.
