i have a 64 bit windows 7 desktop that uses a D-link (DWA-140) wifi usb dongle. It worked fine at another house but at home where my whole family uses the wireless with no problems (d-link router) it will connect but says no internet access. I have tried:
-uninstalling AVG
-refreshing and renewing ip adress using ipconfig
-reseting router
-uninstalling and reinstalling wifi dongle drivers
-forcing plustnet's dns adress
-disabling TCP/IPv6
-turning firewall off

i can happily connect to the portable wifi hotspot on my phone ....
PLEASE HELP!!!!!!!

Might need to remove the connection, then re-add it as a new wireless connection,
let Windows rediscover the dongle and you WiFi.

by Wizard57M-TR

Have you got some sort of maximum number of connections allowed on
your WiFi? Does your dongle work with any other device? Last I can
think of off the top of my head is maybe a DHCP server on the dongle is
conflicting with your WiFi broadcast??

erm i dont think so , iv tried it when everyone else asleep so im assuming no. yh its worked fine in the past and it connects to the wifi hotspot on my phone. ok, so how do i fix that?

Try resetting the tcp/ip stack from an elevated command prompt.

type: netsh interface ip reset.

Restart the computer when it finishes.

by neoprime

Check your network connection setting to make sure it is set to automatically acquire ip and dns address. If it is set correctly you can try the following commands from an elevated commands prompt.

netsh int ip uninstall . Restart computer

netsh int ip install. Restart computer

Also, check your router to see if it is set to hand out enough ip address.

with regards to the router not giving out enough ip's, iv tried disconnecting my laptop before forcing my desktop to have the laptops old ip , still nothing

by james862

ok, so how to i check how many ip's my router is giving out. and how do i fix this?

by neoprime

Open command prompt
type ipconfig press enter
type the address for the default gateway into your web browser
if prompted for a username and password just type admin and leave the password blank

by james862

tried that, browser wouldnt load it , said it was "taking too long to respond"

Now getting "DHCP is not enabled for wireless network connection" after diagnosis...

by james862

windows says its fixed that problem and it no longer shows up but still no internet access

by Wizard57M-TR

and look at the properties for the dongle itself. Make sure it is set to obtain DNS, IP etc automatically. Also, make sure it is not trying to setup DHCP itself, but to use the WiFi broadcaster. It is possible that the network settings from the other house have became set in the dongle.

Ok, i did the ping test. It failed when pinging my routers default gateway ... what does this mean?

by adrian watts

It means I need to see the output of ipconfig/all for both your computer wlan and a working computer wlan as well as what ip you were pinging for your computers ip address and your gateway ip address. I forgot to mention but can you successfully ping your routers default gateway from another computer, post the result of performing the same ping tests here too. If there is no misconfiguration there then it is time to start looking at the dlink forum at the top of the post, but post the outputs first.

Run cmd. type cls->enter [clears the screen]
ipconfig/all
right-click and Select-All
right-click on the menu bar Edit->Copy
paste into notepad. Copy the section ""Ethernet adapter Wireless Network Connection"

If the default gateway is the same on both computers then the problem is that you are not making a successful wlan connection to the router, you are getting dhcp but not actually being allowed through to the router.

I found that Windows 7 and IPV6 have problems, especially on older routers, where there are more than one PC connecting to the local network. I documented the solution in this blog and this has worked well, especially with Windows 7 and Vista.

However, with Windows 8 (especially 8.1), this problem appears to have returned; system tray periodically shows "No internet access". I am still working on a solution -- but suspect IPV6 again...
